Default Re: Lowering a gmc 4000

To get smaller wheels to fit, you'll have to know what kind of space you'll need for the brake drum, I heard some one of 19.5" to fit but they used a custom adaptor.

I got rid of the 20" wheels on my truck, replaced them with 22.5" one piece wheel off a 1960 Chevy L60.

My Truck is a 3500, the smallest of the big trucks, but they all used that same 5-10 bolt pattern, 5 on front, 10 on the rear. all the wheels should have 10 holes.
