C3500 CCSRW 4.5/2 Lift. Wheel Fitment.

I’m in need of the backspacing specs of the factory 16” steel wheels to get the right spacers for my 4.5” front lift spindles.

Did you find any info?

I am interested in the same spec. I am using the Superior SF1 16” aluminum wheels. They have a back spacing of 4.85” based on some minor web searching. I found that the maximum back spacing for the 4.5” lift spindles recommend no greater than 4.625”.

That leaves about .225” too great of clearance. Quarter inch spacer or 7mm is needed.

I don't have the specs but I assume the warning is because the stock wheels will hit the banjo bolt and compress the brake caliper when making full lock turns. A remedy to this is cutting the steering stop off the lower control arms. I ran stock wheels with 245/75/16s on my c3500 with no problems after removing the steering stops.

Ran into the same thing. Freaked me out at first when loosing brakes after a full turn
