TeraFlex Pro LCG long arm suspension systems are an advanced high performance upgrade kit for applications such as the Jeep TJ Wrangler, designed to provide a low center of gravity (LCG) for enhanced off-road articulation and on-road handling. They feature longer, adjustable control arms to optimize suspension angles, replace the stock rear suspension with a 4-link system, and are intended for use with a coilover setup (sold separately). Additional details: * The system uses adjustable, long control arms made of durable DOM steel tubing that mount further back on the frame. This design relaxes the suspension link angles, restoring near-factory geometry, which results in a smoother ride, improved stability, and less stress on components, especially during extreme suspension droop. * Low center-of-gravity design provides excellent ground clearance without raising the vehicle's center of gravity excessively, which enhances stability on varied terrain. * The stock rear suspension and track bar are replaced with a triangulated 4-link system, which eliminates the need for a rear track bar and allows for adjustable anti-squat tunability to fine-tune performance. * Adjustable control arms allow for precise tuning of front caster and pinion angles, as well as optimizing rear pinion angles and anti-squat geometry. * Superior performance: Kit is engineered for aggressive off-road enthusiasts and is ideal for rock crawling and challenging trails, while maintaining on-road capability. * Durable construction: Components are made from CNC laser-cut, precision-bent 1/4 in. thick steel and feature a black powdercoat finish for strength and corrosion resistance.

AEV Conversions first introduced OE-level suspension engineering to the aftermarket over a decade ago. They continue to build on that legacy today, while also broadening their spectrum of suspension performance with the introduction of DualSport XP Suspension System for a variety of Jeep and RAM applications. The factory suspension on many vehicles is soft, lightly damped and with a low suspension frequency. This "soft tuning" can make the handling feel a bit loose and uncontrolled—not the ideal suspension formula for overland enthusiasts who also need to manage lots of cargo and gear when traveling off the grid. As with all AEV expedition-ready suspension systems, coil spring and shock tuning was essential to provide the optimal balance of load-carrying capacity and ride quality that customers have come to expect from AEV. The DualSport XP Suspension System includes a set of frequency-tuned, triple-rate coil springs to provide 2.5-3 in. of additional front and rear ride height. Customers can now fine tune their DualSport XP Suspension System even further by choosing one of two available coil spring options: * 2.5 in. Standard Load Coil Springs are optimized for a vehicle with typical gear/cargo inside. This means the ideal ride height, handling and overall performance will be achieved on a vehicle with steel bumpers, winch, full-size spare and recovery gear (+0-400 lbs. over factory weight). * 3 in. High-Capacity Coil Springs are specifically designed for overland enthusiasts who have a fully outfitted vehicle that is also consistently loaded with heavier gear (+400-700 lbs. over the standard load spring), such as modular cargo systems or roof rack/rooftop tent combinations. These coil springs are then paired with a set of AEV-tuned, Bilstein 8100 Series reservoir shocks for improved performance and consistency over rough terrain at higher speeds. The AEV/Bilstein coil spring and shock combination used in this suspension increases both up travel and down travel, while also providing better articulation and improved off-road speed potential and bottoming control. Even when towing, the suspension feels stable, planted, and confidence inspiring. AEV optimizes front and rear suspension geometry throughout the entire range of motion, tightening up the handling and road feel, resulting in a great ride and performance without introducing harshness or driver fatigue. In the front, a pair of AEV's heavy-duty, stamped control arm geometry correction brackets are included for improved ride quality and reduced nose-dive under hard braking. A rear track bar tower extension is included to raise the rear roll center, reduce body-roll and generate a better turn-in response. Extended-length front and rear sway bar end links compensate for the additional lift height, while new front and rear bump stop spacers improve bumper/axle contact under full articulation and jounce. Due to this suspension system's lower lift height, there is no need to swap out any of the OE track bars, control arms or steering components. Order the AEV Conversions DualSport XP suspension kit recommended for your vehicle!

Rock Jock High Steer Knuckle Kits for all Jeep JL and JT models is a game changer, packed with features that improve the off-road capabilities, as well as the on-road drivability of your vehicle! Intended for use on factory axles, these kits replace the inferior factory aluminum knuckles with cast iron high steer knuckles that exceed OEM quality and strength. They raise the tie rod 2 3/4 in. and the drag link 2 1/2 in., moving the rods out of the way of rocks and helping to restore factory steering geometry for improved drivability and overall road comfort on a lifted Jeep. The new knuckles also feature two adjustable steering stop locations for full lock-to-lock adjustability which helps ease the strain on steering components at full lock. Stock ball joints, unit bearings, axles, brakes and dust shields are all retained. Rock Jock's Currectlync steering included in these kits features revolutionary high articulation forged chromoly drag link that incorporates a unique organic shape with many compound curves—which can only be achieved via forging, resulting in maximum up-travel capabilities. The tie rod is a 42mm (1 5/8 in.) diameter chromoly tube. All Currectlync steering ends are forged steel and comparable in size to those found on modern 1-ton trucks. Given the dramatic geometry changes vehicle lifts impose, the kits include a trac bar geometry relocation bracket with a fully integrated: a) steering stabilizer shock mount, OR b) ram assist steering mount (depending on the kit you order). The trac bar mounting point is raised 2 1/2 in., to correct geometry, preventing any bump steer. * a) The steering stabilizer shock mounting point portion of the bracket moves the shock up and behind the new tie rod location, far from its vulnerable stock location.
