2007 Chevrolet Silverado 1500 LT1 Extended Cab SB 4WD

Both the LT and LTZ trims with four-wheel drive come equipped with Chevy's Autotrac system, which automatically shifts into 4WD when traction loss is detected. Fuel economy for the 5.3-liter V8 with 4WD is estimated at 14/19 mpg. Silverado 4WDs are also eligible for the Z71 Off-Road Package, which adds skid plates, an off-road suspension, and a locking rear differential.

The extended cab is the only Silverado body style that offers buyers a choice between all three bed lengths. This model comes with the shorter bed, measuring 5 feet, 8 inches.

The LT1 trim comes standard with cruise control, cloth seating (versus the Work Truck's vinyl), a lumbar adjustment for the driver, full power accessories, keyless entry, an auto-dimming rearview mirror, and a leather-wrapped steering wheel. LT options include 18-inch aluminum wheels, a power-adjustable driver's seat, an in-dash CD changer, and Chevy's EZ-Lift tailgate.
