TeraFlex LCG (Low Center-of-Gravity) Long Arm Suspension Systems are engineered for hardcore Jeepers who don’t want to give up on-road comfort and control in their TJ Wrangler/Unlimited. These complete systems include all necessary components including LCG Long Arm Brackets. For ultimate rock crawling, trail riding, and high-speed road stability, look no further than the TeraFlex Pro LCG Long Arm Suspension System. These kits are engineered for the aggressive off-road enthusiast who wants the best suspension performance on and off road. Up front, the Pro LCG expands the performance of the stock 5-link suspension configuration with our adjustable LCG Long Control Arms & Brackets. Our Front Upper LCG Long Control Arms are more than 9in longer than stock! Around back, the stock 5-link rear suspension and track bar are replaced by our adjustable Pro LCG Triangulated 4-Link Long Control Arm Suspension w/ Rear Axle Truss & Brackets. The rear upper brackets feature adjustable anti-squat tunability to fine tune the suspension. Our adjustable LCG Long Control Arms balance front caster angle and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 3-5in lifts. On higher lifts, LCG Long Arm Brackets and 4-Link Rear Axle Truss reposition the frame-end control arm mounting points to relax suspension link angles. This reduces bushing stress during extreme droop as well as shock load transferred through the LCG Long Control Arms.
