The rear axle experiences tremendous amounts of lateral force while driving and those effects increase exponentially during off-road driving. The TeraFlex JK: 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 rear right spring clearance. Our Rear HD Forged Adjustable Track Bar is recommended for 4-6in lifts. Bolts into factory locations or one of our Rear Track Bar Brackets – no cutting or welding required. This is the same Rear Track Bar used in our 4-6in Alpine RT and Alpine CT Long Arm Suspension Systems. A must for anyone who takes their rig off road!
