TeraFlex TJ: LCG Long Control Arms and LCG Long Arm Brackets (NOT INCLUDED) provide complete alignment adjustability for maximum performance on TJ Wrangler/Unlimited models with 3-5in lifts. Can be added to an existing suspension lift. Must be used with LCG Long Arm Frame Brackets and/or Rear Axle Truss – NOT INCLUDED. On higher lifts, TeraFlex TJ: Lower LCG Frame Brackets reposition the frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during droop and shock load transferred through the control arms. CAD-engineered LCG Long Arm Frame Brackets and Triangulated 4-Link Rear Axle Truss are designed for maximum strength. The 1/4in-thick steel brackets are CNC laser cut and precision bent for accurate fitment. Frame brackets locate using the factory belly pan skid plate bolt holes then stitch welded. These are the same components found in our high-end Pro LCG and/or Enduro LCG Long Arm Suspension Systems.
