The front axle experiences tremendous amounts of lateral force while turning and those effects increase exponentially during off-road driving. The TeraFlex JK: Front HD Adjustable Track Bars withstand these abusive side loads to dramatically improve steering response and 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 Front HD Adjustable Track Bar is recommended for 2.5-6in lifts. Bolts into factory locations – no cutting or welding required. This is the same Front Track Bar used in our 2.5-6in Suspension Systems (Alpine RT, Alpine CT, Sport ST, and w/ 8 Alpine Short Control Arms). A must for anyone who takes their rig off road!
