The front axle experiences tremendous amounts of lateral force while turning and those effects increase exponentially during off-road driving. The TeraFlex TJ: Front HD Adjustable Track Bar withstands 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. This Front HD Adjustable Track Bar is engineered for TJ Wrangler/Unlimited models with 3.5in or more lift. This is the same Front Track Bar used in our Pro LCG Long Arm Suspension Systems (without High Steer System). This Front Track Bar uses a joint in place of the factory tie rod end and MUST be used with our TJ: High Steer Track Bar Bracket Kit (Front Frame: # 1743031) – NOT INCLUDED. NOT compatible with our High Steer Systems. A must for anyone who takes their rig off road!
