Product Details
Fabtech is known for building robust suspension systems designed for off-road capability. This 8-inch Radius Arm Lift System is engineered for your 2008-2016 Ford F-250 or F-350 Super Duty 4WD, giving you the clearance and damping needed for challenging terrain.
At the heart of this system are the Dirt Logic 4.0 Stainless Steel Coilover Conversion units for the front. These replace your factory coil spring mounts with upper mounts made from 1.75-inch diameter DOM tubing, distributing impact loads across a wider frame section. The lower mounts are a solid 1/4-inch steel, securely attaching to the axle for the Dirt Logic 4.0 shocks. These shocks feature piggyback reservoirs and are constructed from stainless steel. The system also includes billet sway bar end links with heim ends and quad-layer limiting straps to control suspension travel. For the rear, you get 2.25-inch Dirt Logic Stainless Steel shocks.
The patented Radius Arms are built with a full tubular structure reinforced by dimple die side plates. An adjustable alignment cam at the axle allows for precise caster adjustment, which is crucial after a lift. This kit includes front replacement coil springs for a 6-inch lift, a Trac Bar relocation bracket, a Pitman arm, sway bar drops, and a rear block and U-bolt kit to achieve the full 8-inch lift. This comprehensive system aims to provide maximum front suspension damping and improved off-road performance.
