Is there a specific type of lugnut required for a 15x8 procomp rockcrawler wheel with 3.75 bs or can I reuse the stock lugs? Also, do I need to use center caps with these wheels? Sorry for the dumb questions, the last set of wheels I bought this was all included so I am just trying to make sure I have everything I need. Thanks for the help.

 

depends on the rim. obviously the threads didn't change, some rims have smaller deep holes and the stock lug nut won't fit. for the center cap, you don't need to it just makes it look better by covering up the hole.

 

A lot of the ProComp wheels need the Gorilla lugs. Best bet is to contact the place that you're looking to get them from and ask...

 

If i had done that it would not get my post count up! lol.

Called procomp they said 60degree conical seats are the ones to go with. Anyone know if this is what type is used on a stock rubi? Hope this can help others!

 

Yup, same same.

 

Had to use Gorillas on mine. But, I have the alloys, not steel. I think it depends wheel to wheel.
