2005 Chevy Silverado Crew Cab Buildup - Leveling The Playing Field

Raul mounted the Nitto Durra Grappler Highway Terrain 275/60R20 tires onto the new Mamba M2-8 allow 20x10-inch wheels.

Oh what a difference! You can see a major style and size increase in the Mamba wheel and Nitto tire combo.

After mounting all four wheels/tires, Raul used a recently calibrated torque wrench to set the proper 100lb-ft torque settings on each lug nut.

After the wheels and tires were mounted onto the Silverado, it was then lowered to the floor and taken for a test drive to settle the suspension. Chuy used a tape measure to dial in the ride height. Raul was underneath rotating the front torsion bars making final ride height adjustments while Chuy confirmed both the driver and passenger side ride heights.

After setting the new Pro Comp Leveling ride height, the Silverado was driven up onto the alignment rack and hooked up with the wheel laser sensors. Chuy worked his magic of aligning the front end with the rear end so the Silverado would travel straight down the road.

We then took a ride to CGS Motorsports in Pomona, California, where Casey and Ron Scranton would install a new CGS cat-back exhaust system. The CGS Motorsports after-cat exhaust system features an all stainless steel two-into-one 21/2-inch exhaust tubes that enter a polished stainless steel 20-inch baffled muffler. A polished stainless steel outer exhaust tip shield houses the exhaust tube.

A Sawzall was used to cut through the factory exhaust tubes behind the factory catalytic converters. The factory cat-back tubes were then discarded.

The CGS exhaust tubes were inserted into the factory exhaust tubes. The CGS 20-inch polished stainless steel baffled muffler was then connected.

The pre-bent rear exhaust section was routed up and over the rear end housing then welded in place. A CGS polished stainless steel exhaust tip was positioned and welded in place.
