The first on-the-car revalveable shock, QA1’s revolutionary MOD™ Series shock debuted at SEMA and was recognized with multiple awards due to its use of patent-pending dry modular valve packs. These valve packs are now available, giving racers the ability to tune their cars in ways previously not possible.
The MOD™ Series modular valve packs are part of the compression and rebound knobs and determine the actual valving of the shock. By simply unscrewing the knobs you’re able to remove and replace them with new knobs, effectively changing the force curves in just minutes. Utilizing QuickTune™ Technology, the shocks can remain on the car during this swap, remaining free from contamination with no interruption to the oil pathways. Never before could you change the valving characteristics this much without completely disassembling the shock.
All MOD™ Series shocks come equipped with standard (100-650 lbs.) valving that’s well-suited for a variety of racing and driving styles. Racers looking for a higher level of tunability can purchase softer (50-350 lbs.) or firmer (375-1100 lbs.) valve packs depending on the vehicle or current track conditions. Available in rebound or compression, these valve packs are sold in pairs.
