SUP- K840 Superlift Suspension 2005 - 2007 Ford F250/F350 GAS 8" Lift Kit w/ Shocks

The 8" lift for the coil sprung Super Duty is achieved via engine specific coil springs to ensure proper lift height and maintain factory ride quality. In order to obtain the amount of caster correction required for 8" of lift, both Caster Brackets and radius arm lowering brackets (4" drop) are utilized. Lowering the radius arms 8" - the amount required if Caster Brackets were not used - would create unwanted leverage and overly stress the frame rails. Other components included with the 8" system are: front compression travel-stop relocation brackets, track bar relocation bracket, dropped pitman arm, front anti-sway bar extensions, brake line extension brackets, and a steering stabilizer bracket. The kit is packaged complete with Superlift Superide shocks.

Options include multiple steering stabilizer choices including dual Superide SS series stabilizers by Bilstein and a Radius arm to 4-link conversion kit. Note that when using the optional Radius arm to 4-Link conversion kit, the Caster Brackets are not required.

NOTE: If equipped with a two-piece driveshaft, also order carrier bearing drop bracket part number 9695.
