Leaf springs
On the front of the truck, there is a bumpstop right above the front axle. Measure from the top of the axle tube (not the spring or spring plate, but the axle tube) to the bottom of the metal bumpstop bracket. A stock truck is about 8-1/2”- 89GMCJimmy

Axle guy told me it didn't add much benefit, so I removed it. since I'm keeping the little 10 bolt for now I'll drive it till it breaks. It seemed for likely to get caught up on rocks etc...- 89GMCJimmy

modern size wheels that fit squarebody chevies
This is My 1989 Jimmy 4x4 with 15"x8" wheels they have 3.75" backspacing with 1/4 of space between rim and tie rod ends. I believe you can have more backspacing with larger diameter rim? I have also seen and read about some K5's with more backspacing. It may depend on witch tie rods you use. HD...- 89GMCJimmy

Backspace 15" vs 17"
Rory Do you know what is the MAXIMUM backspacing that will fit? My 15" with BS 3.75" is pretty much it, I think slightly more with a 17" rim but not sure how much If a 17" with 4.5" backspace works that would open up many options- 89GMCJimmy

Backspace 15" vs 17"
i'm hoping to reduce some steering play/slop. With the push pull steering it will never feel super tight but it will feel a litter tighter i wanna reduce sidewall height keep 33" over all- 89GMCJimmy

Backspace 15" vs 17"
1989 GMC Jimmy 15"x8" with 3.75" backspace and 1/4-3/8 space between rim and Tie rods If I move up to a 17" rim will a 4.5" back space work? Not too many options for 17" or 18" (simple style) rims with less than 4" back space If this has been answered already sorry I haven't found yet Thanks- 89GMCJimmy
