Last year early summer I changed out my Slee 6" to ~3" Dobinson coils. I chose the c97-144vt 3-3.5" in front and the c59-615v 4" flexi for the rear with plans to put spacers in the front to level it out once the springs settled to ride height. After some testing and measuring I realized I hadn't lost nearly any down travel in front or rear and I enjoyed how much better the truck drove on and off road. I like the very planted and understeery feel with the lowered height in front and decided I don't want to make it taller after all.
I measured my "actual lift height" according to the diagram posted in this thread from Toyota by measuring the coil spring bumper heights. By that scale it appears I have about ~2.75" lift in the front and ~3.7" in the rear according to the 1991-1992 years numbers. I would have guessed more like 3" front and 5" rear by the amount of stink it still has.
With all the spring options listed from multiple manufactures I don't see why there is such a big gap in free heights and not really many variances in options for ~2.5" rear coils. If I want a 1" lower spring than the 3" Flexi the free height of the coil drops by 3.6" in total.
Essentially I'm looking for a true 2.5-3" spring thats free height is as least as tall as my Slee 6". Like a 2" flexi, which would theoretically have a free height of 20.5" but there is nothing even remotely close from any company I can find.
Rear spring specs:
Slee 6" med/heavy- 20.25"/20.7" free height
Dob 4" Flexi- 22.6" free height (these only lowered my height by ~.5" from the Slee 6")
Dob 3" Flexi- 21.5" free height (these only lowered my height by ~.25-.5" from the 4" Flexi)
Dob 2" VT- 21.25" free height (have been told these will be around same height as a 3" Flexi on a light truck)
Dob c59-223v 1.75-2.5"- 17.7" free height (next closest in free height)
No intentions on adding a rear bumper swing out, roof rack, drawers, or fridge. Input appreciated.
The day I put the 3" front and 4" rear in it seemed pretty level.
Dropped down to 3" rear springs after the front settled down.
How it sits now. Kind of a bad angle, but it's pretty much sitting flat and not flexed or stuffed on any corner.
