The rear axle experiences tremendous amounts of lateral force while driving and those effects increase exponentially during off-road driving. The TeraFlex JL: Rear HD Forged Adjustable Track Bar withstands these abusive side loads to dramatically improve handling. Track Bars also allow lateral adjustment of the axle for proper axle alignment as well as cycling through full suspension travel without interfering with other components. Our rear track bar also maximizes exhaust and differential cover clearances. Our Rear HD Forged Adjustable Track Bar is recommended for 2.5-6in lifts. Bolts into factory locations or our Rear Track Bar Axle Bracket (recommended for 2.5in+ lifts) – no cutting or welding required. A must for anyone who takes their rig off road!
