17x 8's fit our trucks. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a nice set of 17x8 Torq thrust knock-offs here i am thinking about for the 75. they have a 4.5" backset. with the 1" thick adapter i will need to make them work that makes it 5.5" backset. With the coil spring only lowering in the front I am sure they will not hit the A-arms and I also want to do only the Shackle drop in the back. I want facts/opinions or ideas. I want full sidewall tires not rubber bands so what do you recommend for tire sizes. Front & rear. thanx, crossy

with the the spacer the back spacing will be 3.5 and for tire a 275/50

I would be concerned with them hitting the fender when you go over bumps if you use the spacer.

You won't need a front spacer...4.5" BS is factory, and because they are 17" wheels...they won't hit/rub anyhow.

I would run the spacer in the rear however, as the rear track with is about 1.5" narrower per side...3" overall./ It'll push out the wheels and make things look sooo much better.

EDIT: You said adaptor...is the bolt pattern NOT 5 on 5 for the wheels or something?

I agree with Jeff. I don't think you would need spacer for the front. Just like he said to make the rear look better.

I think the route you are taking will look sweet on the truck. Something a little more modern, but not too much. Can't wait to see them on there.

yeah, thanx for he math correction factor.duh. lol
the ADAPTER is for the bolt pattern difference not just a spacer. If i dont like the look i may just buy the right bolt pattern for the front in only 7's (if avail) to keep them in.

**crossy** · 12-17-2009, 06:22 PM

found out they make 17x7 in 5on5 pattern but only make 16x8's in 5 on5. so if I buy TWO new ones ??? Ill decide when i compare tire sizes most likely. i know they make EVERY imaginable size in 16" for not much $. 17's get pricey quick. thanx , crossy
