AFCO Racing Terminator SS Spindle-Mount Adjustable Struts

AFCO Racing Terminator SS spindle-mount adjustable struts are built with large 35mm twin tube pistons and deliver a range of adjustment that is un-matched to enhance tuning and performance. Each adjustment of these user-friendly struts is metered with a detent for precise adjustments, and they are available in two lengths to fit virtually every ride height. A perfect choice for a "no prep" style of racing, the "extra travel" models promote additional weight transfer to hook up on low-traction surfaces. For more conventional applications, the AFCO Terminator SS Series struts are available in common lengths to retro-fit to existing chassis in the field or new builds that need to fit an existing jig. Offered with aluminum or steel steering arms and either bushing or caster camber mounts, AFCO's Terminator SS spindle-mount adjustable struts allow for nearly infinite chassis tuning combinations, but more importantly, the broad range of adjustment offered will allow tuners to find the "sweet spot" for their required application setup quickly and efficiently. Features: * Two lengths are available to fit most Super Stock-style applications * 100 percent Dyno tested for accuracy and quality * Double-adjustable 35mm twin tube design provides broad range of adjustment * Fully independent compression and rebound adjustments for ultimate tuning and performance * AFCO Exclusive aluminum steering arm gives better tire clearance * Competitor-style steel steering arm allows you to upgrade to an AFCO strut without having to shorten the tie rod assembly * Pro-style coilover spring adjuster nut has positive clicks with each turn, locks in place with an Allen wrench, and has pronounced finger grips to aid setting ride height—a spanner wrench may also be used to set ride height * 2-piston or 4-piston caliper brackets available * 1967-69 Camaro pin design for common wheel/brake kit fitment * Best front-end control on the market

RideTech 1979-93 Mustang SLA Front Suspension Systems

RideTech 1979-93 Mustang bolt-in SLA (Short-Long-Arm) front suspension systems replace the stock McPherson strut design with a billet aluminum upper control arm, tubular lower arm and spindles with S550 Mustang hubs. The factory strut design offers very little camber gain and poor overall geometry. This design greatly improves negative camber gain, which positions the tire perpendicular to the pavement through the corners without the need for excessive static camber and overly stiff spring rates. Caster, roll center and Ackerman angles were also optimized. These suspension systems are compatible with either Ridetech coilovers or Shockwave air suspension (sold separately). SLA front suspension systems are available in two fitment styles: * To fit STOCK K-Members (except 84-86 SVO) * To fit many AFTERMARKET K-Members, including Maximum Motorsports, Team Z, AJE and UPR Additional product features: * Incorporates an upper control arm to induce much-needed negative camber gain * Caster, roll center, bump steer and Ackerman angles are optimized * Bolt-in frame surrounds create attachment points for the upper control arms and the shocks. This keeps the load on the frame rails for maximum strength and reduced NVH * Upper and lower arms feature Delrin© bushings infused with PTFE to minimize stiction and eliminate the need for lubrication * Spindles include Moog S550 Mustang rear hubs for maximum strength, consistent braking and reduced maintenance * Lower control arm design improves tire clearance and steering angle 30 degrees with up to a 275mm wide tire Fitment: * Uses S550 (15-23) or SN95 (94-04) Mustang brake systems (caliper brackets sold separately) * 17 in. minimum wheel diameter * Compatible with stock and most aftermarket sway bars Specifications: * Negative camber gain: 1.25 degrees/in. * Positive caster: 7-9 degrees * Bump steer: under .050 in. * Lowers ride height: 1-2 in. * 50 lbs. lighter than stock suspension * Stock track width

TeraFlex Pro LCG Long Arm Suspension Systems

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 DualSport XP Suspension Kits for Jeep

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.
