Summit Racing™ Drag Shocks and Struts

Summit Racing™ offers drag race shocks and struts for countless vehicles from the 1950s and up. They're available in a variety of styles for front and rear applications—including 90/10, 70/30, and 50/50. A 70/30 strut extends faster than it contracts, meaning faster front-end lift but longer to settle back down. 90/10's will lift your front-end very fast and settle it back down slowly, keeping the weight transferred to the rear tires much longer than the 50/50 models. Order the drag shocks and struts recommended for your racer.

Steeda S197 Ford Mustang Stage 2 Drag Packs

Steeda's Stage 2 Drag Pack for the Ford S197 Mustang puts even more control into the rear axle assembly with some added durability and tuning capabilities. The spherical upper axle control arm bearing adds the final piece to the puzzle for the ultimate in axle control. A stainless steel, custom spec'd, PTFE lined bearing is what you'll find in the billet steel bearing housing machined in-house. Weld-in lower control relocation brackets are included to let you adjust how hard you hit the back tires. Unlike competitors' brackets, which have failed countless times, Steeda's are weld-in only to provide the most strength possible. When used in combination with the Stage 1 (not included), you'll have the ability to adjust mounting locations for the upper and lower control arm adding tune-ability to your rear suspension. The added sidewall allows tires to absorb the shock of the launch much better, resulting in quicker 60 fts. and ET's. Steeda's sway bar relocation bracket enables you to run 15 in. wheels and tires on the back of your S197. Lastly, with all the added traction and compliance in the rear suspension, you want to limit chassis deflection. This is where Steeda's exclusive chromoly 3-point lower torque box and frame rail brace come into play, tying together the inner and the outer frame rails, along with the lower torque boxes. Kit Includes: * Steeda upper axle spherical bearing * Steeda control arm relocation brackets * Steeda frame rail and torque box brace * Steeda rear sway bar relocation brackets and installation hardware Note: Not for use on 2011 and newer V6 Mustang, due to lighter front end.

Koni SPA1 Drag Race Shocks

Koni SPA1 drag race shocks work differently than the 90/10 shocks you're probably used to seeing. Rather than letting the front rise quickly and stay up during launch, Koni's front shocks allow the front-end to rise quickly and then settle down faster to reduce front-end drag and improve your ETs. These shocks have five settings to help you tune your chassis. Koni's rear shocks help keep your rear-end planted by stiffening up as you run over surface irregularities, minimizing rebound and keeping the tires on the track. These shocks are for drag racing only; they are not designed for highway use.

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.

TeraFlex Jeep JK Wrangler 1.5 in. Spring Leveling Kits

These TeraFlex leveling kits are ideal for mild trails due to the increased ground clearance and the ability to fit larger diameter tires. They improve approach, breakover, and departure angles.

BMR Suspension Caster Camber Plates

BMR caster camber plates add caster and camber adjustability and fix alignment issues. Manufactured from CNC laser-cut steel plate, BMR caster camber plates also replace weak factory strut mount bushings with high-quality, PTFE-lined spherical bearings. Their design increases camber adjustability and adds caster adjustability that isn't available from the factory. These adjustments also help reduce unwanted tire wear from too much negative camber. BMR Suspension designed these kits for street performance, drag race, and handling applications. They are 100 percent bolt-in, and most are available in black hammertone or red powdercoat. The kits use existing bolt holes and include the hardware required for easy installation. Once installed, the caster camber plates allow you to add aggressive alignment settings for both the street and track. This helps to keep the largest possible tire contact patch for autocross and road race applications.
