Another backspacing question..... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

laplander · 09-14-2011, 10:53 PM

I see all these build threads with different backspacing on their trucks, both front and rear. I have a set of 17x8 wheels with 4" backspacing. Am I going to run into any problems with a 3.5/6 drop? I thought 4" was a safe number when I bought them, but now after reading what everyone else has, I'm begining to wonder.
Thanks.

You should be fine with a 17" rim.
I ran some 17x8's with a 5" BS with no issues.
(BUT,... all wheels are different)

Check fitment with the wheels turned and straight.
