so i got a hold of some pretty banged up black iroc-z rims and im painting my 91 sierra black so will the iroc-z rims fit the truck???

 

how many lugs does your truck have . if it's 5 like the iroc then that will fit the backspacing may be way off though.

 

ya its got five lugs....... so you think theyll fit, probably need some spacers tho you think.

 

Just because theres five lugs doesnt mean the bolt spacing is the same. Im pretty sure they're different but I dont know.

 

ya now that i look at it they might look pretty goofy anyways but it would be nice to know if they fit so i don't have to lift the damn thing up just to find out they dont fit....... im guessing they don't fit cuz i haven't seen anybody do it and couldn't find anything about it on these message boards and the ppl on this site have tried everything imaginable when it comes to thirdgens or thirdgen parts

 

Iroc 5x4.75 BC

Sierra 5x5 BC

 

sorry about that didn't realize they had a different size bolt pattern i thought all gm 5 lugs were the 5x4.75 sorry about that one.

 

But the older full sized Chevy cars (Caprice/Impala) use the same 5x5 lug pattern. So you could grab a set of 17" Impala SS wheels to throw on your truck.

5" drop up front/5" drop out back But I had to do some front a-arm trimming because of the drop, otherwise they are a direct fit.
