2009 Chevrolet Silverado 1500 LT1 Ext. Cab 4WD

The addition of a four-wheel-drive system to the 2009 Chevrolet Silverado 1500 LT1 Ext. Cab 4WD not only improves the vehicle’s performance in poor conditions, but it also modifies some of its specs. The 4WD's maximum payload is 1,773 pounds, down from 1,847 for the LT1 Ext. Cab with rear-wheel drive; maximum towing capacity is 5,473 pounds, up from 4,700; and mileage is 14 city/18 highway mpg, nearly identical to the LT1 Ext. Cab's 14/19. Front tow hooks come standard on all Silverado 1500 trims with four-wheel drive.
