Our patented Radius Arms feature a full tubular structure strengthened by dimple die side plates, with an adjustable alignment cam at the axle to allow caster adjustment. This system also includes replacement front coil springs, and the choice of Fabtech’s Performance, Stealth, or Dirt Logic Shocks. You can also choose to upgrade the front end with our coilover conversion and massive Dirt Logic 4.0 shocks.
