Competition Engineering Adjustable Drag Shocks

These Competition Engineering adjustable drag shocks offer a 3-way valving system to dial-in the extension/compression ratio needed for any track condition. The front shocks have three adjustable ratios of 90/10, 80/20, and 60/40. The ratios for the rear shocks are 70/30, 60/40, and 50/50. These numbers represent the percentage of force required to extend (first number) and compress (second number) the shock. By changing the settings on the front and rear shocks, you can dial-in the car to raise the front on initial launch for weight transfer, and then settle smoothly for a final charge to the finish line.

SPL Suspension Camber Arms

SPL Suspension camber arms increase stability and response by eliminating bushing deflection and offer a wide range of camber adjustment. They're designed for use in high performance street and race vehicles. Without factory camber adjustment, many lowered cars require an adjustable control arm to achieve your desired alignment settings to maximize tire wear and handling. Three-position mounting holes for sway bar end links and shock mounting allow you to alter geometry to prevent end link binding, quickly adjust motion ratios, and resulting spring and sway bar effectiveness. Simply put, it's like having adjustable spring rates without a spring replacement. Using FEA (Finite Element Analysis), SPC's CNC-milled 6061-T6 billet aluminum camber arms are designed to exceed factory strength and durability. The exclusive Hybrid Adjuster is comprised of electroless nickel plated 4130 chromoly. SPL blue anodized titanium hardware and 6061-T6 aluminum clamps help reduce weight and prohibit corrosion while offering quick and easy adjustment. Order the pair recommended for your vehicle.

Elite Series springs are made from chrome silicon high-tensile steel and are lightweight. They deliver the most travel with no loss in spring height or rate. As always, Landrum Performance Springs provide the tightest tolerances in the industry—and you always get a dyno sheet to prove it! Don't settle for the anything less but the best when it comes to suspension performance. Elite Series springs are available in a variety of heights, diameters, and dozens of spring rate options (from 50 lbs./in. through 1,000 lbs./in.). Elite Series front coil spring features: * Available in front or rear coil spring applications (specify when ordering) * All front springs are closed and ground on one end to provide proper contact with the jack plate, not forged * All rear springs are closed and ground on both ends, which ensures proper contact with the jack plate and spring seat * The opposite end is either open or closed tangential to fit properly into the lower control arm * Cold wound, not hot wound, so each coilover spring is properly heat-treated and stress-relieved to ensure sides of the spring remain parallel during installation * Powdercoated, not plated, to protect the spring from hydrogen embrittlement, a corrosive breakdown of the spring's surface which decreases the spring's life * Each spring is designed with the correct pitch and height ratio to ensure consistent rate throughout the entire cycle

Fox Racing Shox Factory Race Series Float 3 Evol QS Shocks

Fox Racing Shox offers Factory Race Series Float 3 Evol QS shocks for a variety of applications, including many Polaris, Lynx, and Ski-Doo snowmobiles from 2015 and up. They are the lightest mountain sled suspension packages available. Ride harder in the backcountry with less fatigue without a compromise of durability. Experience a new sense of control on the snow due to less outboard weight. Fox designed the air-sprung mountain shocks with two primary objectives: weight reduction and ride performance. The shocks are optimized through material reduction without a sacrifice of ride quality or structural integrity. Engineers shaved weight from the reservoir walls and mounting hardware to save weight where it counts. The result is an air shock package in a league of its own. Fox's position-sensitive damping technology, with origins in desert truck racing, is now applied to the Factory Race Series coil-sprung shocks. Spiral grooves inside the shock allow the oil to flow around the main piston, reducing damping force in the ride zone for a plush feel. The bypass grooves terminate through the final 30 percent of the travel, forcing oil to only flow through the main piston—and providing a significant increase of bottom-out resistance to cushion any hard hits. Fox's QS technology allows you to adjust the compression and rebound damping with ease to suit the snow conditions. Three positions keep the adjustment simple, so you focus on the ride instead of counting clicks. The Float air spring and Evol air chamber have an infinite range of spring adjustment. The air spring enables you to tailor the suspension specifically to your ride style or terrain. When the shock compresses through the travel, the spring force ramps up due to the progressive nature of air springs. If you ride aggressively and want a bottomless feel, the Float 3 Evol QS shock package is for you. Maximize the power-to-weight ratio of your sled by bolting on Fox's new mountain shocks.

Fox Racing Shox Factory Race Series 1.5 Zero QS Shocks

Fox Racing Shox offers Factory Race Series 1.5 Zero QS shocks for a variety of applications, including many Polaris, Lynx, and Ski-Doo snowmobiles from 2011 and up. These Quick Switch (QS) coil shocks are the next generation of lightweight mountain sled suspension technology. Ride harder in the backcountry with less fatigue without a compromise of durability—and experience a new sense of control on top of the snow due to less outboard weight. Fox's QS technology allows you to adjust the compression and rebound damping with ease to suit the conditions. Three positions keep the adjustment simple, so you focus on the ride instead of counting clicks. The rear track is also equipped with a lockout mode to prevent trenching the next time you get in the deep snow or climbing steep faces. Fox designed the coil-sprung mountain shocks with two primary objectives: weight reduction and ride performance. They optimize the 1.5 Zero coil-sprung shocks through material reduction without a sacrifice of ride quality or structural integrity. Additionally, the coil springs were redesigned to retain the same spring rate but with fewer coils and built from a lighter steel alloy. The shocks maintain a linear feel regardless of temperature fluctuation, which keeps your sled setup quick and simple. The new coils result in a spring with the same performance at half the weight. Fox's position-sensitive damping technology, with origins in desert truck racing, is now applied to the Factory Race Series coil-sprung shocks.
