QA1 Rear MOD Coilover Conversion Systems

QA1 MOD Series coilover conversion systems put the ability to re-valve your shocks—on your car—into the palm of your hand. These innovative shocks feature QuickTune Technology, an industry-first that provides the ability to adapt to any track, any conditions, any time. The technology consists of interchangeable, dry modular valve pack assemblies, that can be thought of as dozens of finely tuned shocks you can hold in the palm of your hand. They define the valving curve of the shocks, and can be changed without interrupting the oil pathways. Simply unscrew from the shock, bolt-in another one with a new pre-determined valving range—and you're ready to go. There's no mess, no contamination, no air intrusion, and no downtime waiting on someone to re-valve your shocks. Ideal for Circle Track and Street/Strip applications, the shocks are available in a variety of extended and collapsed length models to best fit your vehicle. You get everything you need with these QA1 Rear MOD systems, from shocks to nuts and bolts, complete installation instructions, and even decals! Additional benefits and features of QA1 MOD Series shocks: * All new design delivers force, control, and unmatched tenability * Hard anodized aluminum bodies with PTFE—durable, non-galling surface * Double-adjustable shocks with low-speed bleed adjustments * Large solid piston (with blow-off valve)—improved driver feel and control with up to 1,600 lb. force * High-speed valving adjustment (coarse adjustment)—relates to shock operation during impact events, like hitting a pothole or curb * 24 clicks/settings—wider range of adjustment than comparable shocks * Indexable base eyelet—multiple mounting position to optimize knob access and provide more mounting flexibility * Low-speed valving (fine-tune adjustments)—adjusts ride quality and weight transfer on corner entry/exit; more bleed for softer feel and less bleed for stiffer feel * Piggyback or remote canister options * Unique spring adjuster nut and tool * Thrust bearings included * Superior thermal performance, as oil is in constant contact with outer body * One base shock can be upgraded over time to keep up with increased performance levels of your vehicle

ST Suspensions XTA Plus 3 Coilover Kits

ST Suspensions XTA Plus 3 coilover kits give your car maximum performance for the road and the tools you need for any challenge. From the factory, these kits are equipped with KW dampers that are adjustable in high- and low-speed compression, as well as adjustable rebound damping. With 24 clicks of adjustment for each, high-speed and low-speed compression damping and 18 clicks of rebound adjustment, your suspension knows no limits. It doesn't matter if you bolt in an aftermarket roll cage, weld in a cage, modification to PU bushings upgrade to spherical bushing or changed wheel loads—XTA Plus 3 coilovers have what it takes to keep your car dialed! Of course, the XTA Plus 3 also includes a parts approval certificate, race springs, and aluminum unibal top mounts. Order the model recommended for your vehicle. * Easy lowering adjustment: Like all ST coilovers, the lowering adjustment is made via a continuous thread on the galvanized strut. This allows the lowering to be made even when the kit is installed by turning the spring plate higher or lower. NOTE: The lowering of each vehicle differs greatly with ST XTA Plus 3 coilovers due to the type of construction. * KW Engineering, exclusive for ST suspension: The high-quality ST XTA Plus 3 coilover is based on the twin-tube damping principle of low friction combined with pressure-resistant damper housings. Manufactured directly at KW, a mono block guide and seal package reduces the friction of the damper, as well as protecting it against corrosion and dirt. Each galvanized strut is sealed multiple times to ensure maximum longevity in ALL weather conditions. Features: * Latest damping technology for maximum longevity * Reduced system friction for effective damping adjustment * Individual lowering within the tested adjustment range * Front and rear axle (when possible) with thread adjustment * Galvanized coilover struts with additional coating for an optimized corrosion protection * Complete solution with adjustable spring plate, race spring system and bumpers with dust protection * Aluminum adjustable uniball top mounts (when possible) * Scaled camber adjustment (optionally also caster), when possible * 3-way adjustable dampers: - 18 clicks low speed rebound damping - 24 clicks low speed compression damping - 24 clicks high speed compression damping

Icon Vehicle Dynamics 3.0 Zeta RR Secondary Shocks

For high performance Ford Raptor suspension components, ICON Vehicle Dynamics is an industry leader. With their 3.0 coilovers and bypasses, billet aluminum upper control arms, and bolt-on rear bump stop system, drivers of ICON-equipped Ford Raptors are able to push their vehicles to a whole new level. It's this level of off-road abuse that prompted ICON to develop a 3.0 Secondary Bypass shock engineered to work perfectly with the Camburg Performance Dual Shock Lower Control Arm kit. The addition of this 3.0 Secondary Bypass means rougher terrain and larger off-road obstacles can be overcome with speed and confidence. With the turn of a knob, the compression and rebound damping of these shocks can be tuned to perfectly complement the rest of ICON's Raptor suspension products for an unparalleled level of on and off-road performance. The ICON Ford SVT Raptor Secondary front shocks are a 3-tube external bypass shock with remote reservoir. These are far from the norm when compared to a traditional bypass shock you see on trophy trucks and other off-road race vehicles. Each bypass valve has a specific port design and is individually equipped with a different spring rate to ensure proper performance at each zone of shock travel. These same bypass valves feature damped valve seats for quiet and precise operation. That means no clicking noises as you hit bumps or road chatter driving down the road. The biggest difference in these shocks versus an industry standard bypass shock is the "Easy-to-Adjust" knobs and the replaceable bypass tubes. The "Easy to Adjust" hi-resolution clicker knobs do not require any tools for adjustment, and can be adjusted in seconds for the demand of the terrain you'll be facing. Another unique feature of this shock is the replaceable bypass tubes that can be swapped out during a standard rebuild if any damage were to occur, where a normal bypass shock body would need to be completely replaced, saving you hundreds of dollars. Features and benefits of Icon Vehicle Dynamics 3.0 Zeta RR Secondary Shocks: * Further increases front damping ability of the Raptor in off-road conditions * East-to-adjust bypass knobs allow for quick changes to shock without the use of tools * Hydraulically damped bypass valve seats are engineered to attenuate the loud bypass clicking noise transferred to the cab that is common with other brands * High resolution bypass valves designed for noticeable fine-tuning of rebound and compression damping * Digressive rebound on main piston in conjunction with calibrated external rebound valve preload facilitates good low-speed characteristics. This is in contrast to most bypass shocks that are designed primarily for high-speed use only * Compact bypass tube design allows ICON to fit 3 bypass tubes where others could only fit 2, allowing for more adjustability of the shock * Compact tube block design keeps bypass tubes close to the body, providing maximum clearance from tires and other suspension components * Replaceable bypass tubes can easily slide into position in case of damage * Multi-stage cad plated finish with polished and anodized top cap / rod ends
