4x4 rear diff width - The 1947 - Present Chevrolet & GMC Truck Message Board Network

my rear diff is 2 1/2" overall narrower than the front diff, the front looks good with the 33's, but the back looks like the tires are too tucked in, I was thinking of 1 1/4" wheel adaptors, anyone have this problem, any thoughts on this

I have the same look on my truck with 31's front tires mount flush to wheel opening and the back tires are set in aboot an Inch to 2 Inches...I guess I've learned to live with it but It will change when I get the time...any tips?

if your game for wheel adaptors, a friend of mine is a ex machinest, I'm going to run the wheel adaptor thing by him and see if he can make some for me, if they turn out right I'll see how cheap he can produce some, and I'll let you know, if your interested

When I originally bought my truck the rear rims had a different backspacing to make them stick out. The fronts were 4" the back was like 2.5" looked good but meant the tire did not get rotated. Supposedly GM vans came with wider rear axles than the trucks. You could swap one in.
