Upgrade your rear upper short control arm suspension to an adjustable Pro LCG Triangulated 4-Link Long Arm Suspension System with this Rear Upper Pro LCG Triangulated 4-Link Long Control Arm & Bracket Upgrade Kit. Provides complete alignment adjustability and dependability for maximum performance on TJ Wrangler models with 3-5in lifts. Can be added to an existing suspension lift. On higher lifts, the Rear Upper Pro LCG Triangulated 4-Link Long Control Arms, Frame Brackets, and Rear Axle Truss (INCLUDED) convert the stock 5-link rear suspension to a triangulated 4-link suspension for increased flex while eliminating interference w/ other components. Repositioning the frame-end and axle end control arm mounting points relaxes the suspension link angles, which reduces bushing stress during extreme droop as well as shock load transferred through the LCG Long 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. Requires Lower LCG Long Control Arm & Bracket Upgrade Kit (# 1447700). Combine this kit with the Front Upper Pro LCG Long Control Arm & Bracket Upgrade Kit (# 1443470) to step up to our full Pro LCG Long Arm Suspension System.
