Show original supplier description
The SuperLift K638B-SUP suspension lift kit provides a 6-inch lift for 1999-2004 Ford F250 and F350 pickup trucks. The rear lift is achieved using 5-inch blocks, and the kit includes both front and rear Bilstein shocks. This kit features military-wrapped spring eyes and anti-friction pads between the leafs for enhanced durability. It is proudly assembled in Louisiana and backed by a limited lifetime warranty against defects in materials or workmanship. NOTE: This lift kit includes rear blocks and U-bolts configured for F-250/F-350 pickups with factory 1 7/8" blocks and without top mount overloads. If your vehicle is equipped with the factory 3.71" block or top mounted overloads, a longer rear U-bolt will be required and is available separately. The recommended tire and wheel fitment for this kit is a 37 x 12.5" tire on a 17 x 9" wheel with 4.5" backspacing. However, due to variations in tire dimensions and wheel offset/backspacing measurements between manufacturers, it is important to fit-check your tire/wheel selection prior to purchasing, as backspacing significantly impacts tire-to-fender clearance when turning.
