Rear Block Kit for Silverado & Sierra 1500

About this part

Rear Block Kit, fitment-checked

Contents are spelled out on this part where most are not: solid cast iron blocks, a locating pin, E-coated U-bolts, and the nuts and washers to go with them.

Knowing exactly what is in the box is rare in this data, so it is worth stating plainly — solid cast iron blocks, a locating pin, E-coated U-bolts, nuts and washers. Coverage runs the Chevrolet Silverado 1500 and GMC Sierra 1500 from 1999 to 2018, taking in the SS on the Chevrolet side and the XFE on the GMC side, plus the 2007 Classic bodies and the GMC Yukon XL 1500 Denali for 2007 to 2009. The shock extension bracket kit PN 67-3809 is recommended alongside it.
