havoc 315:
You are in the moog spring rate topic.
None of the moog springs are "lift springs".
Some can be used as a lift spring though.
The part numbers 5662 and 5664 are the ones that will fit an s-10 (v-8 Camaro spring).
They lift the front in the 1 inch to 1-1/2 inch range, work, fit and perform well.
You are very limited with the stock a-arm on an s-10.
The most you can expect to reasonably spring lift stock a-arms is 2 inches.
You can squeeze more out of stock arms but it is not recommended, especially if offroaded.
Ok now to answer your questions.
1) Springs- aftermarket. CST, AIM, Fabtech to name a few. Will need at a minimum upper a-arms plus welding and cutting on the upper arm mount.
2) Spindles- Yes lift spindles do exactly that.....Lift. I would start here instead of with springs.
Start you a build/question thread instead of replying here in the sticky.
Everyone will jump in and help you out.
