Yes. I installed a front sway bar and left the stock suspensión intact. Works great! Still compliant, mostly.

So @Shooter920 and @RB Suibian

You're both running factory suspension with the sways? RB are you running an upgraded rear bar as well?

This is great news! It would be awesome to be able to keep the compliance when the car is 'set' so to speak and gain a bit better steering feel in turns.

Woo!

 

Yes just front anti sway. Huge improvement but once you drive it a week you will feel the rear one is necessary. Wifey say “hell no!” I only have front!

#2 Megan Racing MRS-TY-1291 25.4mm hollow bar - VERIFIED fitment (~$176 USD)

Megan racing rear bar above says it's only for FWD cars. Is this actually true or is the install just more involved for the awd vehicles?

 

I can’t answer that unfortunately because I have front wheel drive.


2010 RAV4 V6

 

Ordered F/R MR sways and the 3rd row seat rear springs (moog from rock auto).
I should probably order new f/r endlinks too right? Guessing these haven't ever been changed out because why would they be.

Eh... whatever. Ordered moog F/R endlinks as well.

 

Might as well. I had to do the right rear sway link last year when I did my springs because it broke when I removed it. Six months later the bushings of the remaining original are shot, so guess what I’m doing on Sunday? With mine being a 2012 from the last month of production, it would have been the very last one to show age-related failures... but it’s paid for!

Has anyone tried out OEM NX sway bars? Part number 48818-78030 indicates a 24mm bushing for the rear sway bar (presumably solid) on certain 2017+ models. That's getting close to the 25mm bar for a fraction of the price if us RAV owners can grab one used on eBay. That is what I was able to do when I put a 26mm (vs stock 23mm) 2nd gen Highlander front sway bar on my 1st gen for next to nothing.

Our V6 AWD measured 21mm in the rear and 25mm in the front, but I know even 3mm would be a nice improvement. This car understeers heavily compared to my Highlander where oversteer can be induced if you want. It does have larger sway bars (26mm solid front, 22.2mm solid rear w/ heavy-duty brackets) but I feel like the rear RAV4 shocks are extremely soft, which isn't going to help that understeer. 2020 NX300 F-Sport shock absorbers are going on soon so I'll report back on how that goes. The end goal however, is going to be us running Bilstein B6s on the car.

Alright, some good news! I have compiled a list of all of the compatible factory sway bars our cars came with as well as the NX ones if you want to upscale the thickness of your front or rear sway bar. We recently got 3rd row springs and the 2018+ NX300 rear sway bar as it is 24mm and the largest rear sway bar available for us for the price. A lot cheaper than the 25mm solid version out there and my friend is on a budget. It came with new end links which he needs as well for his car! Should stiffen up the rear nicely and hopefully allow us to induce some oversteer like my Highlander.

The sway bar and bushing MFR region has no effect on fitment, it's just where the part itself is made (NA vs JPN). The NX bar I got fit our NA-made RAV with no issue,

VERY interesting. Did you already install this?

The "48812-78030" bought doesn't appear to be the same shape as my RSB. Have you installed this yet? Is your Rav4 4WD? If it does fit, that is a nice cheaper "factory upgrade" option for sure!

My Rav is FWD/4WD.
Are all the part #s above interchangeable?
I don’t want to buy something from an AWD and it not be a direct fit. Sorry if this was already explained. Just figured to ask.

 

Just to update this thread, I did the front and rear Megan racing F/R sways, moog endlinks, and 3rd row springs. I'm very pleased with how the car feels for a daily driver at this point.

Likely not going to do anything with the suspension unless I want to lower it in the future which I don't really see happening anyway.

 

I’ve found some time to install the bar and springs this weekend. It is indeed an AWD (incl the donor Lexus NX). This sway bar is MASSIVE, makes even my aftermarket Addco on my Highlander look kinda skinny. Should be 42% stiffer than the stock 22mm bar according to the sway bar stiffness formula. Might try to get a matching set of Lexus NX front struts as well to compliment the rear shocks.

Wait, the lexus NX struts are a direct swap? Different damping etc?

Yeesh, all these newer posts with folks finding oem parts to fit makes me feel silly for having spent a bunch on the megan bars. Atleast mine are prettier! 😂

 

Yes they do! So do the NX sway bars! (Stock was 22mm, NX was 24mm solid as expected). 3rd row springs were a nice compliment as well. They have an extra coil on them, but are the same thickness. Transfer over your old coil spring isolators and sleeves.

The rear has been stiffened up nicely! The 2018+ NX (non-hybrid) sway bar is the best bang for buck for sure! OE bushings fit perfectly in the original brackets and the sway bar end links were identical as well. Will post updates after more driving.

Excellent find and great contribution to the group with the part numbers! [emoji122]

 

Thanks! This was definitely a worth-while upgrade. All-in-all it only set us back around 250. My friend wanted to retain comfort so we decided to pass on the lowering springs for this application. We’re very impresed with how it drives now! Super smooth still and it corners a lot more flat in the back. I may have to take the end links off again soon and clean the rust off, as the shaft seems to have expanded, so the bushing isn’t fully seated it seems.

$70 - Lexus NX F-Sport rear shocks from a 2020
$125 - 2018+ Lexus NX300 24mm RSB w/ hardware
$62 - MOOG 3rd row seating springs
$7 - MOOG end link bushing kit (Not designed for RAV4 but fit perfectly)

A universal set of Moog bushings replace the original 225k cracking and rotted ones. The bushings will fit as long as they’re designed for M10 sway bar links. Nut size is M10 x 1.25. I used some sway bar end link nuts from a newer Highlander and they fit perfectly. Moog bushings were made by Ramcoa and are US-made. Nice and stiff compared to stock!

 

Nice man!

I swapped the megan front sway bar first with the moog endlinks and 3rd row rear springs and it made a huge difference. A few weeks later I installed the megan rear sway bar and it drives exactly how I'd hope this car would drive. I know I've mentioned this before on this thread but everything feels so much more planted during turns and the OE comfort/cushy ride is completely preserved. I was so sketched out by this car on my first hard drive! My last daily was an 06 acura TL and I also keep a miata around, so I have some basis for comparison about stable and firm cars (TL) vs stable and playful with heaps of body roll (miata).

Pretty good comparison in terms of feeling. The stock miata is great and has a ton of body roll for chassis feedback. The rav4 just has a ton of body roll. Sway bars, bushings, better endlinks, and 3rd row springs really make the cars handling worthy of the V6 power. Just like better suspension makes the miata into the momentum car it really should be.

 

At the time of posting this, there appears to be an Ultra Racing 23mm solid rear sway bar advertised as available for the 3rd gen Rav4. Ultra Racing brand is pretty well known for supplying upgraded suspension parts across many vehicle platforms. The only front option is from HardRace, a 28mm hollow option. HardRace appears to be MeganRacing's Australian division who's shipping prices make the products unrealistic.

After finding out that another Australian company called MAKO wouldn't ship their cheaper custom made sway bars to the States, I was pretty frustrated. See the following thread: Custom front and rear upgraded sway bars for V6

I brought this up on several FB Rav4 groups and even got several Australians to offer to re-ship the MAKO for me. But not wanting to have to inconvenience anyone, I kept looking for an option stateside.

Apparently, the front sway bar amongst other suspension parts on the 3rd gen Rav4 is shared with at least 6 other Lexus/Toyota/Scion vehicles on the New Toyota MC platform ..Cars and SUV's on the same platform sharing the same suspension. Found this out by talking with 84hachi, a buddy I met through instagram and FB rav4 groups and Paul Sexton @toyotechwv on PriusChat.com who had swapped a 2011 Rav4 sway bar into his SCCA autocrossing prius. Long story short, the cross platform use by Toyota/Lexus/Scion is coming in handy.

UPDATED!

Scion xB E150 2008-2015

Here are the FRONT sway bar options we've discovered so far - most of which are not advertised as working for the 2006-2012 Rav4. I rated these in order based off price:stiffness ratio. Keep in mind the XA30 Rav4 oem size is 25mm:

#1 Hotchkis 22429F 32mm hollow bar ( ~$143 USD) - VERIFIED fitment .
#2 Megan Racing MRS-LX-1290 32mm adjustable hollow bar (~$180 USD) - VERIFIED fitment
#3 Cusco 925-311-A30 30mm hollow bar (~$300 USD) - VERIFIED fitment
#4 Hardrace 7996 28mm hollow bar (~$280 USD) - UNVERIFIED fitment

Lucky for us the 3rd gen Rav4 also shares rear suspension parts with several other Lexus/Toyota platforms also.

Toyota Rav4 XA30 2006-2012
Toyota Rav4 XA40 2013-2018
Toyota Harrier XU60 2013-2018
Lexus NX 2014-present

Here are the REAR sway bar options so far - keep in mind the XA30 Rav4 oem size is 22mm:

#1 Cusco 978 311 B25 25mm solid bar - VERIFIED fitment (~$303 USD)
#2 Megan Racing MRS-TY-1291 25.4mm hollow bar - VERIFIED fitment (~$176 USD)
#3 Ultra Racing UR-AR23-171 23mm solid bar - VERIFIED fitment (~$348 USD)
#4 HardRace 7997 25.4mm hollow bar - UNVERIFIED fitment (~$287 USD)

My rule of thumb was that the solid bars were going to be stiffer but heavier than the hollow and lighter options and hollow would need to be 2mm bigger than its solid counterpart to be comparable. Meaning the hollow Megan Racing rear sway bar at 25.4mm is relatively the same stiffness as the Ultra Racing solid 23mm rear sway bar.

Knowing this cross breeding on platforms may open up other XA30 Rav4 suspension options... !!

Fantastic post. Thank you! Exactly what I needed.

 

Oops. Saw the part in post above.

 

Hi, friends! I have been lurking this thread for quite some time now and I thought I might share my next big upgrade (Tuesday can’t come soon enough!).

After hyper analyzing the options for front and rear sways, I decided to go with Hotchkins FSB/Megan Racing RSB & MOOG endlinks. I picked up the MR rear brace as a combo with the RSB (eBay special) for $165 shipped. The Hotchkins FSB is impossible to find ANYWHERE (seriously looked/called/etc) and was able to find the full set on eBay for $339 shipped. Anyone with a 2008-2012 xB want a RSB for a good price? lol.

Anyways, I’m a fan of suspension mods. I have Bilstein b6’s and Northwood performance springs on all 4 corners…I can’t wait until the upgraded sways are installed. Also have the ultra racing front strut brace, which was very difficult to install due to the cramped engine bay. I picked that up from Alek’s Racing for $210 shipped (from Malaysia!) It actually made a significant difference in stiffening up the RAV in case anyone is wondering.

I’m attaching some pics for reference. I’ll post an update when everything is installed!!! Also, massive shoutout to TEKSMRT for all his help and for starting this post. Have a great weekend, friends!

Did I read that correctly that yours is a 4th gen?

 

Yessir, 4th gen 2018

 

Nice to see the research for the 3rd Gen suspension is being utilized for the 4th Gen as well. Keep us posted on how it improves handling! [emoji1417]

 

Hello, friends! UPDATE

I had the sways, endlinks, & rear brace installed on Tuesday and wanted to drive it for a day before posting. My RAV is literally stuck to the ground with minimal body roll in the twisties. I live in an area that has many hairpin turns on my daily route…RAV is much much flatter on my commute and is so much more enjoyable to drive.

If you are looking to improve the stock shopping cart-like handling, I highly recommend the suspension mods I have made.

Here are some details about my car:
2018 (4th gen) LE FWD, 42k miles

Suspension mods (in order of install):

• Bilstein b6’s on all 4 corner
• Northwoods performance springs (stock ride height, no lift)
• Ultra racing front strut brace
• Megan racing rear brace
• Hotchkins front sway bar
• Megan racing rear sway bar
• MOOG endlinks
• Also picked up some Goodyear assurance maxlife tires @40k, took off my hubcaps for that blacked out look

Attached are some pics from the install, enjoy!

Nice! Ain’t it fun 🤩. Just waiting for the Hotchkis front SB. They’re impossible to find right now.

 

I know it's late but I've got a new hotchkis front sway bar and a cusco rear bar I'm looking to get rid of if anyone is interested. Local pickup would be preferred if you live near southern Missouri. Bought them a few months ago and ultimately decided not to install them.

 

I'm not local, but I am interested in the Hotchkis front sway bar if you are willing to ship. Is it the 22429F? Let me know what you're asking and if you can ship to 18036. Thanks.

 

I know this is an old thread but it seems like the right place to ask for instructions on rear sway bar removal. Folks that have replaced theirs, what did you need to disconnect, besides the sway bar end links and the sway-bar to frame mount bolts, to remove yours? I don't see a place where I could pull the rear sway bar out once it's disconnected. I'd appreciate instructions/pictures if someone can help with that.

 

You need to pull at least one rear spring out. Pretty easy on our cars thankfully, one bolt on the lower control arm / cradle and it’ll pop out.

 

I disagree I was able to remove it without spring removal. Obviously have the rear lifted and supported. Both rear links and the mount to frame.

Haven't tried the front. Yet...

 

I never tried it without removing the springs as I was doing those anyway. Good to see it can be done without removal of them.

 

So I got both of the Cusco sway bars that are mentioned in here front and rear. I have only installed the front bar so far. it seems like it's actually worse taking hard corners in the front. It feels like I'm skating more. I have decent tires with good tread. My question is would putting the rear bar in as well solve the skating in the front or would it add to the problem?

Yes, you’re probably experiencing excessive understeer because the front bar by itself is stiffening / taking away too much traction from the front. The bigger rear bar will make the car a lot more neutral and competent around corners. While keeping it flat overall.

I had the opposite effect on my Highlander as I did the rear bar first. The rear was way too tail-happy and was robbing the overall potential grip that it was truly capable of. This went away with a slightly larger front sway bar. I kept the overall bias more rearward to cut out the factory understeer that Toyota designed it to have. Ideally (in my case) the car should be pretty neutral with a small trace lift-off oversteer should you demand it. This was achieved on the Highlander with a 26mm front (stock was 23) and 22mm rear bar (stock was 16) (w/ custom stiffened brackets I made).

My friend’s V6 2011 RAV came with a 26mm front (stock) and a 22mm rear, but the 24mm NX300 bar made the car a lot more neutral, a bit less than the Highlander. These cars will have a larger rear sway bar than rear strut cars like the older Highlander as multi-link suspension setups usually have the bar mounted on the control arm rather than the more rigid strut, demanding the need for a larger bar to achieve the same affect.

 

I am thinking my fsb on my 2010 Rav v6 sport is around 26mm.. is there a point to upgrading the front bar to the NX 27mm? I want to do the rear and would like to do them as a set to keep everything neutral. But not sure if I’ll see any benefit…

 

Thanks, I appreciate the input. It gives me some piece of mind. Guess I'll try and change the rear this weekend which should be fun trying to take out the rear spring to get access. The stock front is 26mm and the rear is 22mm. The new front is 30mm hollow bar and the rear is gonna be a 25mm solid bar. Hoping both will pair well enough together.

 

Sounds like you already did the hard part, although I’ve never looked at the front sway bar / removal on the RAV4. On my 2002 Highlander and 2008 RX350 platform of cars on the Camry chassis need to have the steering rack, front struts and rear engine mount removed for easier access to remove the front sway bar, really not fun to do unfortunately.

The pairing of a hollow 30 front and solid 1” / 25mm rear sounds like a good combo, should really cut down on the body roll and put a little more bias to the rearend. Seems as if Toyota resorted to stiffer sway bars to try and control lean in corners rather than stiffer springs on this platform. Unfortunately, that made our ‘11 V6 AWD have a lot of nose dive and slop, but the Lexus NX springs got rid of the majority of it.

 

The front was a bit of a pain, took me about 4 hours due to clearance issues and some stuck bolts. It was pretty simple though. Disconnect the sway bar links on both sides, unbolt the 2 brackets underneath the frame, you need to jack up the transmission to get clearance to fully remove the front lower control arm bolt. Tried jacking from the engine first, but the engine mounts held it and lifted the entire car. Swing out the control arm, remove sway bar.

I looked at the rear before and damn that's gonna suck with the differential in the way. Even more so if I have to remove the rear shock that I have to use a crescent wrench on since I don't have enough clearance to get a socket on it.

Also could i get some more information of the nx springs and where to get? A few years ago I switched out the front to kyb quick struts to get rid of the nose dip, but after a couple years it came back.
