CST Performance SuspensionCST Performance Suspension's '97-'03 F-150 long-travel kit gives you 13 inches of working suspension travel, and because this kit uses 1-inch heavy-duty uniballs and Delrin upper control arm bushings, you receive the optimum amount of travel with great durability. Installing the long-travel arm kit, 3.5-inch lift spindles, and 8-inch travel coilover shocks will boost your truck as much as 7 inches, extending your track width 3 inches per side.

Kelderman ManufacturingKelderman Air Ride has recently developed an air ride lift kit for '03 4x4 Dodge 2500 and 3500 trucks. The kit replaces the factory coils with a heavy-duty four-link system. The four-link system is very durable and eliminates the wheel hop that is found with the factory leaf springs. This is a bolt-on kit that requires no cutting or drilling. A large 12-volt air compressor is included with the kit, as well as a pressure switch and an air tank. The front portion replaces the factory coils with a large long-travel, high-capacity airbag. Longer trailing arms replace the factory units to keep the axle in the correct location. Because it's on air, the kits allow the truck to ride at different heights.
