The 2008 Chevrolet Silverado 1500 LT1 with the Extended Cab and Short Box (SB) features a four-door design, seats up to six, and offers 53 cubic feet of cargo space in its rear bed.

The LT1's cab includes driver- and passenger-side recliners, plus a fold-down center armrest with storage space. Drivers can store additional cargo in the lockable underseat storage area that includes a power outlet. The 60/40-split rear bench seat can be flipped up when not in use to provide additional cargo space. Select Cloth seats come standard with the Silverado LT1, but drivers can upgrade to optional Custom Leather seats, as well as an optional six-way power-adjustable driver's seat.

A 295-horsepower, 4.8-liter Vortec V8 engine powers the Chevy Silverado 1500 LT1 Extended Cab SB. The engine links to a four-speed Hydra-Matic automatic transmission designed for smooth, quiet shifting. The transmission includes a Tow/Haul mode, which enhances performance when pulling a trailer or hauling heavy loads.

Standard features for the Silverado LT1 include power windows and door locks, remote keyless entry, a tire pressure monitor, OnStar, cruise control, and an AM/FM audio system with an MP3 input jack.
