2008 GMC Sierra 1500 SL 4dr Crew Cab 5.8 ft. SB (4.8L 8cyl 4A)


This truck replaced my 2001 GMC Sierra 4wd with the 5.3 motor. The throttle response on the 4.8 motor is pathetic. The traction control is overly sensitive, and the truck jumps out of passing gear too soon. The truck is comfortable, quiet, and handles well. The brakes are a major improvement over my previous 2001 Sierra. I love the lighter weight of the tail-gate.

Best Features

Comfortable ride.

Worst Features

A more responsive throttle. GM needs to go back to a throttle cable. The brake pedal is too high in relation to the gas pedal.
