Product Overview
soft or firm compression and rebound valve packs also available. Once the desired valving is in place, the unique double adjustable design, with adjustable low-speed bleed, allows for fully independent control over the compression and rebound characteristics.

The shock also features mounting adjustability to accommodate a variety of vehicles and mounting configurations. The nitrogen-charged canister is available in a piggyback or remote configuration for ease of installation in tight areas, and the base eyelet is indexable, so you can unbolt it and reattach it at the angle you need for the best shock and canister placement. Like all QA1 shocks, the MOD Series shock is 100% dyno tested and serialized and proudly made in QA1's Lakeville, Minnesota facility.

Coilover Shock, MOD Series, Double-Adjustable, Aluminum Body, Black Anodized, Twin-Tube, 15 in. Extended, 10.630 in. Collapsed, Each
QA1 MOD Series coilover shocks 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.
Additional benefits and features of QA1 MOD Series shocks:
• 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

Designed specifically to meet the demands required by today's high performance drag race and handling/pro-touring cars, QA1's multi-patent-pending MOD Series shock will transform the way racers respond to changing track conditions and configurations. The key element to this tunability is QuickTune Technology: dry modular valve packs that can easily be swapped out, all while the shock remains on the car. An industry first, the MOD Series shock can quickly and easily be revalved without interrupting the oil path or opening the shock up for debris and air contamination. Medium compression and rebound valve packs come standard soft or firm compression and rebound valve packs also available. Once the desired valving is in place, the unique double adjustable design, with adjustable low-speed bleed, allows for fully independent control over the compression and rebound characteristics. With all these adjustability options, the MOD Series shock achieves an expansive force curve capability and an unprecedented level of tunability. The shock also features mounting adjustability to accommodate a variety of vehicles and mounting configurations. The nitrogen-charged canister is available in a piggyback or remote configuration for ease of installation in tight areas, and the base eyelet is indexable, so you can unbolt it and reattach it at the angle you need for the best shock and canister placement.
