6 lug 4x4 wheels - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi I have a set of weld scorpins with 305-70-16 goodyear wranglers.They were on my 99 z71,I sold that truck.

My question is would the bolt pattern be the same as the 71-72 4x4's?

I have been trying to sell these, I've been looking for a 71-72 4X4 and' if I dont sell them I would like to use them if they will fit.

Lug pattern is the same but I think the IFS trucks run a different offset. The factory 15x8 rallys used from 70-91 on the solid axle trucks run a 3 5/8's back space. on a steel wheel they can run a 4 inch and it just clears the tierod ends...I mean just clears. The weights have wore a groove in the rubber boot on my tierods

On a aloy wheel the bead area may be thinker and might not clear the tie rod ends.
The way to measure the back space is take something lay it accross the the tire. measure down the bead are of the rim (where the weights go) then measure down to the mounting surface. subtract the 1st measument and that will give you a rough idea on your offset. Less than 4 inches and it should fit the older trucks.
