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. TeraFlex Enduro LCG Long Arm Suspension Systems are designed for the off-road enthusiast who wants to increase both trail and on-road performance with moderate modifications to the vehicle frame. The Enduro LCG uses the same lower adjustable LCG Long Control Arms & Brackets as the Pro LCG, while our adjustable Rear Upper Short Control Arms bolt to the factory upper control arm mounting points. The Enduro LCG provides more suspension and steering adjustability than a standard short arm kit. Our long and short adjustable Control Arms balance front caster angle and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position. On 3-5in lifts, LCG Long Arm Brackets and/or 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. The HD Adjustable Front Track Bar, Drop Pitman Arm (4in+), and Rear Track Bar Bracket improve steering response, center the axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling. This results in improved suspension geometry and relaxed control arm angles for a superior ride quality and performance regardless of terrain. These systems restore front and rear roll axis angles to minimize brake dive and acceleration squat. TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH). These are the only shock absorbers engineered to work with TeraFlex lift coil springs to improve both compression and rebound for optimal vehicle stability. Falcon Series 3.0 Piggyback Shocks are available separately for 3-4in lift heights.
