Im looking for opions. I have a 1989 Chevy 1500, that is going to be my dezert toy with 5 on 5 bolt pattern. Is it beneficial to switch to 4x4 bolt pattern, 6 on 6.5? Thanks for the help.

Actually the Chevy 1/2 ton 4x4 is 6 on 5.5, while 3/4 and 1 ton are 8 on 6.5. You will want to replace the stock rear axle in that truck for prerunning or hard playing anyway, plus wheels for 6 on 5.5 are common, so the answer is probably yes.

Very good info, thanks. How hard is it to do the front? Is it the same as putting new rotors on?

Its not an easy swap. The 5 on 5 trucks are 2wd, so the 4wd parts will not fit. You may be able to redrill the hubs you have now, or step up to a kit with new uprights/spindles and arms, but that will be expensive. Check with BMS and others who make LT kits for chevys.

Actually i had a 93 silverado 1500 2wd and installed a 6 lug rear end, so to match the rear i converted the front to the 6 lug,
hub/rotor off of a 93 2500 witch was 6 lug. the spindle and bearings are the same. and it was that easy you should ook into that before anything else.
