AccuAir Suspension Jeep Dynamic Lift Kit Systems

Find adventure with AccuAir Suspension's advanced and proven dynamic lift kit systems for Jeeps--complete kits that allow for total versatility when it comes to on and off-road fun. And, while air springs and air lift kits are not common on Jeep suspensions, these kits give you capabilities no other Jeep has. More than a lift to ride higher and more comfortably than factory spring and shock kits; with AccuAir dynamic lift kits you will have the option to raise and lower your Jeep at the push of a button. AccuAir dynamic lift kit systems lower to stock level for garage entry then automatically adjusts to 3.5 in. of lift. While off-roading under 25 mph the Jeep can be adjusted to 5.5 in. of lift. The underbody mounted air tank is regulated onboard air for inflating tires and tools. The system automatically adjusts to optimal ride height at speeds above 25 mph. These dynamic lift kits will auto level your vehicle, a must when towing, and overlanding enthusiasts can easily level their Jeep for overnight stops. The fully bolt-on system includes new lower control arms, sway bar links, and front track bar for increased strength and FMVSS 126 compliant handling.

AEV Conversions DualSport XP Suspension Kits for RAM

AEV Conversions 3 in. DualSport XP suspension systems are available for various RAM trucks and are focused on optimizing suspension/steering geometry and application-specific shock tuning to deliver the best possible on-road comfort and handling—while also providing an ever broader spectrum of off-road performance, thanks to the AEV/Bilstein XP8100 reservoir shocks included in this system! HD Ram trucks are built with literally dozens of different spring rates based on the powertrain, wheelbase, options and more, so offering a generic "gas" or "diesel" spring would have been a huge compromise in ride quality and/or load carrying capacity. AEV retains the factory front coil springs and pair them with 3 in. cast aluminum coil spring relocation spacers to achieve the additional lift height. This allows AEV to take advantage of the full range of factory spring rates and frequencies while still providing the necessary front end lift. The AEV/Bilstein XP8100 reservoir shocks included with the DualSport XP suspension system are constructed from aerospace-quality billet components and tuned by AEV to work in perfect harmony with your outfitted HD Ram. The AEV tunes shocks use the same target weight as their Prospector/Prospector XL turn-key conversions to ensure that you get the absolute best possible ride quality and handling, without the degradation in performance, commonly associated with the added weight of bumpers, winch, full size spare, tent, etc. Steering geometry is corrected by way of AEV's high steer kit, which includes a custom, no-drill forged drag link, AEV track bar and raised track bar tower. This system provides significant improvements to steering precision and handling by correcting the roll center height of the front suspension and bringing the steering geometry back into factory alignment. This results in reduced body roll and bump steer, which are major contributors to the loose or sloppy steering and driver fatigue commonly associated with many lift kits. For many of the same reasons that AEV chose to retain the factory front coil springs, 2 in. rear coil spring spacers are included with Ram 2500 suspension systems to provide the necessary lift height without sacrificing ride quality or load carrying capacity. AEV also includes a set of bump stop spacers, rear track bar relocation bracket, sway bar end links and a new power hop bracket (if applicable). The OE leaf springs are retained, and new cast iron blocks are installed to provide 2 in. of lift in the rear on Ram 3500 trucks. Ram 2500 Air Ride and 3500 Air Assist systems are also available. Front Axle Relocation Kit: The factory radius arms are repositioned for optimal geometry, moving the axle forward 1.0 in., which was engineered to use a 37 in. tire. This provides a more neutral impact response, while also allowing more clearance for larger tires. A billet aluminum front driveshaft spacer is included to accommodate the new front axle positioning. AEV also offers a 1.6 in. axle forward kit, which was engineered to use a 40 in. tire. For additional peace of mind, the DualSport XP suspension system is backed by AEV's Lifetime Warranty. Order the kit recommended for fitment on your vehicle.

RideTech 1973-74 Nova Air Suspension Systems

RideTech 1973-74 air suspension systems fit a variety of vehicles—including Chevy Nova, Pontiac Ventura, Buick Apollo, and Oldsmobile Omega models. These packages allow you to achieve that ultra-low show stance and feature several components that will dramatically improve the suspension geometry to give your classic muscle car modern drivability. Each system includes front and rear HQ or TQ Series ShockWaves, upper and lower StrongArms, tall spindles, bolt-on 4-Link and front MuscleBar. Order the model recommended for your application. Additional product details: * Tall spindles will induce more negative camber gain to maximize tire contact patch during cornering. They also offer a 2 in. pin drop which allows for the use of longer shocks, creating more suspension travel * Upper StrongArms feature corrected ball joint angles for the tall spindles. The upper ball joints have been moved back to allow for additional caster setting to improve high-speed stability and steering feel. Offset slugs are also available for additional caster. Injection-molded Delrin® bushings with 13 percent PTFE are used to reduce deflection and stiction * Lower StrongArms feature a double sheer lower mount for increased strength. RideTech also dropped the lower shock mount to increase suspension travel and moved the lower ball joint forward to increase caster settings while keeping the wheel centered in the wheel opening. Injection-molded Delrin® bushings with 13 percent PTFE are used to reduce deflection and stiction * Shockwaves utilize an impact-forged aluminum body and monotube design to deliver excellent ride quality and handling. They allow fine-tuning of the ride quality and handling; the rebound knob is located at the top of the shock for under-hood access * Front sway bar reduces body roll and creates room for wider front tires. Includes billet aluminum frame straps (anodized black) and low friction bushings * Bolt-on 4-Link greatly improves traction, handling, and ride quality. Installation does not require any major modifications to the floor pan and requires only minimal welding to the axle tube. Works with mini-tubs. The R-Joint rod ends combine the best qualities of low friction movement, lateral stability, full range articulation, and quiet operation into one special bearing that is as home on the street as it is on the race track (Noe: Some 1973-1974 cars have a different shape frame rail and require kit number 11260297. See instruction manual for identification details.)

ADS Race Bypass Shocks

ADS external race bypass shock options are designed around racing first and foremost. Performance, reliability, and longevity are primary concerns when determining flow rates and zone placement. Multiple zones allow end users to dial in the damping curve to driver and chassis type. Enhanced flow in critical areas reduces heat buildup and harshness; these reductions in restriction amplify traction potential and driver control. Large capacity reservoirs aid in cooling as well as reducing pressure gain in the system. Large diameter shafts increase strength for extreme applications and stand up to the abuse of racing time and time again. All these features together deliver a bulletproof bypass shock that is guaranteed to perform on your race car or weekend warrior. Options include: * 3, 4, or 5 tubes * Style 1 or 2 * Remote or piggyback reservoir * Dozens of extended/collapsed length options * 8 in. to 18 in. stroke options
