Zone Offroad 4.5 Inch Lift Kit W/ Radius Arm Diesel I ZOND78F

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.
