Front shocks and coils are great. I purchased the set up with heavy duty springs all around. My issue has always been with the rear springs. 3rd gen 4runners are known for the rear end sagging and I bought this kit with the heavy duty coils and it still sags. I’ve never had weight in the back, trunk is completely empty, no spare tire, nothing but a full tank and it still sags. Obviously not nearly as bad as the oem springs but the rear end still noticeably drops. Now I’ve been adding mods, I got a rack and tent up top, the front looks great but the rear is sagging even more with the added weight. I want a rear bumper with spare tire carrier but clearly my springs won’t be able to handle that direct weight in the back end. With a metal bumper in the back, my front end will be pointed upwards. Others who have these springs don’t seem to have this issue so maybe I got an unlucky set? It’s unfortunate.
