2006 Chevrolet Silverado 1500 HD LT1 Crew Cab 4WD

Chevy's 4x4 system may also be equipped with an optional off-road package, including a heavier-duty suspension and skid plates. A separate Limited Edition package includes a performance suspension, 20-inch wheels, a locking differential and towing preparation kit.

The well-appointed LT1 trim comes standard with cruise control, dual-zone climate control, a CD audio system, keyless entry and full power accessories. The LT1 is differentiated from the lower level trims by the addition of an auto-dimming rearview mirror. This truck's 5.3-liter V8 produces 310 horsepower and is mated to a four-speed automatic transmission.

The crew body is only available with the shortest of the three Silverado bed options, which measures 69.2 inches.
