I am in the process of installing pro comp 4" rear springs (pn# 33311) in 85 toyota, and I am wondering if anyone has ran these and what to expect in the way of ride, settling and flex off road.

 

Id like to know too.Mine are sitting on the floor in front of my rig waiting to go on.

 

i have those springs on my runner all the way around and they are STIFF. i should have just spent a little more and gotten a good lift, the ride is harsh at best on road, ive never really wheeled it since i put these springs on tho, so i cant tell ya on the flex part. if your puting them on a pickup expect an even harsher ride since your trucks rear end is lighter.

 

I have rancho springs, not sure what lift size they are, but they shoud be pretty similar to the pro comp springs. as the previous poster mentioned, they are really stiff. my front springs are 3 thick leaves, what are yours? my springs manage off road but articulation could be better and is pretty uncomfortable driving on anything but smooth road. I would consider removing a leaf from the spring packs as long as they arent really low leaf packs like my front ones are.

 

well I didn't get them installed yet either, ran in to a problem with the bolts coming out of the old ones. so i got out the cutting wheel and now have to find some new pearch bolts and steel bushings Also ran the cutting wheel into the top of my knuckle on my index finger and screwed my back up at the same time. As to the front spring I have allpro 4" stock length and bilstiens. Ruff riding but i have not had the chance to pound them off road yet, also haven't mounted the winch and heavy bumper yet.
