2007 Chevy Silverado - San Diego Silverado

After removing the waxy undercoating with a rag and brake cleaner, Frankie measured the crossmember stub 3 inches back from the inside edge and cut it out. Then, he gave the bare metal a coat of black paint. We kept the scrap piece, in case we ever decide to return the truck to stock.

With the rear crossmember cut for clearance, and the front drop crossmember loosely hung, the differential was installed with its drop brackets. The three brackets on the differential adjust for the proper pinion angle and new driveshaft.

Speaking of the new driveshaft, here it is. It's fitted with a universal joint on the transfer-case side to eliminate vibration.

Using the lift again, Frankie positioned the new hub and spindle assembly and the lower A-arm.

An aluminum driveshaft spacer was added to each side to compensate for increased track width and suspension travel. You can also see the rear crossmember drop bracket in this photo. Like most of the Pro Comp kit, it's made from 3/16-inch steel.

Sway bar drop brackets and brake line mounting tabs finished the front, but the crown jewel of the Pro Comp suspension was the MX2.75c coilover. They look good and improve handling, especially with the 35-inch rubber that it was bolted onto.

This gratuitous spark photo actually shows the rear add-a-leaf and lift block that level the truck's stance in the rear.

MX6 adjustable shocks tame the rear of the truck and can be tuned for different terrain. Like the front, a new mounting tab was necessary. However, the factory brake lines were long enough, even at full droop.

These steel clips keep the spring pack from splaying apart. The clamp made sure that there will be no rattles here.
