Sorry if this is redundant but I'm not seeing how to search the 25,000 posts on the 4.1 forum for this specific topic. Anyway, I'm thinking i'm due for rear springs. The 1998 RAV has always had a slight list to the right which is odd considering the driver is on the left. Lately I've noticed it doesn't take much weight for it to bottom out or sag in the back..... a trip to Costco or a couple passengers in back. So, my question is, what are some good springs for this rig? I'm not trying to make a "monster truck" or mimic the ride of a "hard-tail" Harley but I do occasionally tow a small trailer or small boat. I've been known to come somewhat close to the tow weight limits, somewhere between 1,000 and 1,500lbs but it's always within the tow limits and tongue weight. I'm reading that Bilstein shocks are also the way to go with this. Any thoughts?
