2006 Chevrolet Silverado 3500 LT1 4dr Extended Cab 4WD LB Trim Overview

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. While the lighter duty Silverado 1500 and 2500 extended cab models offer buyers a choice between all three bed lengths, the 3500s are long bed-only, regardless of trim, cab size, engine or drive train and wheel configurations. This bed measures 97.6 inches, and aids the one-ton truck's impressive 5000-pound payload.

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.
