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. 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. Like all QA1 shocks, the MOD Series shock is 100% dyno tested and serialized and proudly made in QA1's Lakeville, Minnesota facility.

Don't be limited to adjustments! Completely re-valve in minutes with the QA1 MOD Series Pro coilover systems. 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 shocks 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 shocks remain on the car. An industry first, MOD Series shocks can easily be re-valved without interrupting the oil path or opening up the shock for debris and air contamination. Medium compression and rebound valve packs come standard; soft or firm compression and rebound valve packs are 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, MOD Series shocks achieve an expansive force curve capability and an unprecedented level of tunability. The shocks also feature 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 and reattach it at the angle you need for the best shock and canister placement. Like all QA1 shocks, MOD Series coilovers are 100 percent dyno-tested and serialized. Order the kit recommended for your vehicle.
