Lift kit question

[Me89'Jimmy]

I bought a quote unquote 4 inch suspension lift about a week ago, its from a 74 k5, the guy put it on his 77 k10, his wife didnt like it so he sold it to me for 100 dollars. First of all will it fit my truck (89 Jimmy) and second 4 inch blocks are supposed to be 4 inches from top to bottom right

4" blocks not nessecarily. Should be 4" at some point, depends how they are tapered. How big are they?

i got "4 inch" springs for the front and "4 inch" blocks for the rear. I measured from the top of the high end to the bottom (on the blocks) and it was only 2 and a half inches /forums/images/graemlins/angryfire.gif

that would sound like a 2" lift.

If you're set on 4", compare your springs arch to some you KNOW are 4. Maybe an off-road or tire shop would have some in stock you could compare. You got a good enough deal (assuming it includes everything), I would just install it all and see how it looks and rides for a while. You could always sell it again for a $100 bucks. Measure your height gain after install and let us know. /forums/images/graemlins/thumb.gif

comparing springs may not help that much, spring rates play a good part inthe lift, could be less arch but higher spring rate and that would give same height. It is a good idea though.
