GM Van to Truck Hub Conversion Kit


Silverado knuckles and Chevy Express knuckles are similar but they do not directly interchange. The K series knuckle is too short for the vans to keep your ride height correct and your camber within spec. If you bolt a K series hub up to the G series knuckle, the brake caliper bracket and pads also do not align correctly with the rotor.

This simple CNC cut powder-coated mild steel spacer gives you just the right adjustment to run a K series hub on your G series van knuckles, you don't have to swap your brakes, knuckles or upper control arms. Just drop these right in with your new hubs and you've got a safe and affordable drive-ready system to transfer power from your front CVs to the wheels.
