Rear Block Kit for GM HD with Trailering Package

About this part

Rear Block Kit, fitment-checked

Specified for trucks with the trailering package, and the year split runs differently for each size: the 2500 HDs end early, the 3500 HDs start where they stop.

Two things to match before ordering. The first is equipment. This is listed for trucks with the trailering package, which changes what is under the back of the truck. The second is the year split, which is not the same for both sizes: the Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD are covered 2011 to 2015, while the Silverado 3500 HD and Sierra 3500 HD pick up at 2016 and run to 2019. Contents are solid cast iron blocks with an integrated locating pin, E-coated U-bolts, nuts and washers.
