ADS offers direct-fit race coilover shocks for a variety of applications. They're available in non-adjustable or single-adjustable (with 20 valving selections) models. These coilovers were born from years of desert racing experience. Performance, reliability and longevity were the primary concerns when they were in development. Each part has a purpose, from the screw- in end cap reservoirs to the captive lower spring perch. Extended threaded bodies allow for larger range of adjustment on dual rate spring setups. Heavy-duty adjustment collars prevent thread skipping when adjusting preload or crossover engagement. Truncated threads prevent dirt and debris from jamming into hardware.

The Factory Race Series 3.0 Internal Bypass shocks from Fox Racing Shox use the same race-proven, position-sensitive damping technology as their external bypass shocks raced on trophy trucks, in a compact and hassle-free package. This level of technology takes your utility vehicle from capable to incredible, especially if you plan to race, ride dunes, or blast across the desert. While Fox 3.0 shocks are larger than stock, they're lighter because of their aluminum bodies and reservoirs vs. the heavier steel bodies and reservoirs of stock shocks. Fox's patented Internal Bypass Technology (IBP) allows damping control to vary based on where the piston is traveling inside the shock. The position-sensitive damping of IBP combined with the velocity sensitive damping on the main piston means that these shocks have been fine-tuned to adapt to the harshest terrain, no matter the size of whoops or the speed that you want to hit them. Available in front or rear applications. Select the Fox Factory Race Series 3.0 internal bypass shocks in application you need. Key features: * Race-level shocks—ruggedly built with hard-anodized aluminum bodies and reservoirs that resist corrosion * Independent high- and low-speed compression adjusters, wide-range rebound adjusters, and a true dual-rate spring package with adjustable crossover rings provides the control to fine tune the shocks to your exact needs * Position-sensitive internal bypass damping tubes * Velocity-sensitive valved, high-flow damping piston * 7/8-inch hard-chromed shafts for smooth operation and longer seal life * PTFE-lined spherical bearings for smooth, durable movement * Carbon black dual-rate race springs with crossover * Bolt-on installation * Custom spring packages for Race or Desert and Dune conditions

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

ADS Race MBR coilovers feature Multi-Stage Bypass Ring technology--a genuine multi-stage bypass system where each zone is independently adjustable via a positive stop helix system. This ensures ample flow, like 7-tube external bypasses on 16 in. stroke variations, and internal free bleed ports enable tuners to optimize the damping curve for specific vehicle needs. A true top-out zone provides both mechanical and hydraulic damping, guarding against shock damage during full extension in harsh conditions, although the use of limit straps is recommended for racing and severe use. Additionally, the 4-way adjustable reservoir allows independent high and low-speed adjustments for compression and rebound events. A dual hose system establishes a genuine recirculating fluid path to the reservoir, maximizing fluid cooling with internal diverters, ensuring fluid flow across the entire shock body for enhanced cooling efficiency. Each unit undergoes vacuum bleeding and features full synthetic fluid to reduce fade and extend product life. Select the stroke needed for your vehicle. Features: * Large 2.5 in. reservoirs increase fluid capacity to aid in cooling * High-temperature seals prevent blow-by, ensuring consistent performance across a wide temperature range * Threaded end caps prevent contamination from external sources * 3-stage urethane seal package delivers unmatched sealing performance, suitable for extreme cold snow-ridden trails and scorching deserts alike

Spidertrax Off-Road Ultimate steering knuckles set the standard for rock crawling and rock racing performance. They now include 7/8 in. spherical bearings and 4340 Spider shoulder bolts across the line. In addition, they feature internal gussets on both upper outer knuckle and lower inner knuckle, adding crucial strength from extreme steering forces and those high impacts from jumps. Ultimate knuckles are designed for Ultimate unit bearings, Ultimate U-joints, and 4140 bolt-on high steer arms (sold separately). They install on any Spider 9 housing with 3 1/2 in. O.D. tubes. * CNC-machined: Tight tolerances are necessary for proper fitment. Post welding, all inner knuckles are CNC-machined. This provides not only a perfect 7/8 in. spherical bearing fit but a precise tolerance between upper and lower spherical bearings. No guesswork, no compromise. * 7/8 in. bolts and bearings: The spherical bearing assembly consists of a 4340 Spider shoulder bolt, shim washer, spherical bearing, shoulder washer, and Type C nut. Combined, each knuckle can withstand over 21,500 lbs. of axial loading and over 130,000 lbs. of radial loading. No grease, no weak links, no hassle. * 50 degrees of steering: An OEM-style 60 knuckle can turn only 38 degrees. Ultimate knuckles can turn all the way to 50 degrees, tighter than any steering knuckle on the market. Plus, the use of a 6-bolt interlocking chromoly steering arm makes them one of the strongest, as well (steering arms sold separately). * Internal gussets: Ultimate knuckles take performance to an all-new level with the addition of internal gussets. Upper outer knuckle gussets add critical strength for steering, while lower inner knuckle gussets add extra strength for those high sailing jumps. They're simply Spidertrax's strongest Ultimate knuckle yet.
