Improve both on and off-road performance with the Zone Offroad 6" lift kit for your F250 or F350 Super Duty. The full length coil springs are designed specifically for the weight of the diesel engine. A set of radius arms that bolt in place of the factory arms are included to correct caster. These heavy duty arms are built using high strength 1/4" steel. They are boxed and fully welded with 2.5" greasable bushings designed to isolate road vibrations. A dropped pitman arm and track bar bracket keep the steering linkage angles in phase for predictable handling.Kit ComponentsEngine specific front coil springs Radius ArmsTrack Bar Relocation Bracket Pitman arm Rear add a leafsRear Block Kit Front sway bar brackets Brake line brackets Bump stop extensions Steering Stabilizer Four Nitro Shocks All Necessary Hardware Detailed Install InstructionsKit FeaturesLifetime WarrantyIncreased ground clearanceNo stacking blocksImproved ride qualityView kit installation instructions</strong
