Features & Benefits

  • Heavy duty 1/4" steel, laser cut, internally gusseted radius arms improve strength, offer more ground clearance and correct caster.
  • High strength progressive rate front coil springs for a great ride on any terrain.
  • Front and Rear HD track bar relocation brackets to correctly position both axles under the truck.
  • Forged drop pitman arm to correct steering angles.
  • HD transmission crossmember and t-case indexing ring to correct front driveline angles.
  • Nitro series gas or FOX adventure series IFP gas shocks to improved ride and offroad performance.
  • Allows clearance for up to 37" tires

Up front, a pair of progressive rate, diesel-specific, 4.5" coil springs provides the extra height and smooth handling in the harshest of terrains. A forged drop pitman arm is supplied to correct steering angles. Polyurethane bump stops limit up-travel, while brake line relocation brackets will allow your suspension to easily reach "full droop". To correct the front suspension geometry at the new height, a pair of heavy-duty replacement radius arms is provided that bolt directly into the factory location. These new arms are massive upgrade to the factory stamped units, built from 1/4" American made steel, and internally gusseted with a lower cam adjustment to dial in front end caster. A heavy-duty replacement transmission crossmember as well as a transfer case indexing ring repositions the front driveline output to allow use of the factory drivelines by correcting angles and allowing you to maintain use of 4WD. In the rear, 2.5" heavy-duty coil spacers are supplied to level out the stance and allow you to retain factory ride quality without effecting tow capacity. Extended rear sway bar end links and new bump stops are included to compensate for the lift, and a track bar bracket re-centers the rear axle.
