QA1 Rear MOD Series HD Pro Coilover Conversion Systems

The MOD Series shocks included with QA1 rear MOD Series HD Pro coilover conversion systems are designed specifically to meet the demands of today's high-performance drag race, pro-touring, and track cars, which require higher force curves as their performance levels increase. They feature a unique, double-adjustable design with variable low-speed bleed. This allows for fully independent control over the compression and rebound characteristics, making these among the most capable shocks currently available. The key elements to this range of adjustment are the QuickTune valve packs--modular valve packs available in multiple force curves that can easily be swapped out without completely disassembling the shock, an industry first. Get low and high-speed compression with adjustable rebound when your order the QA1 rear MOD Series HD Pro coilover conversion systems best suited for your application.

Product features and items include:

* Impressive force curve capability and high level of precise tunability while still on the vehicle
* Patented QuickTune™ valve packs in MOD Series shocks allow re-valving to be completed in minutes without interrupting the oil path and opening the shock
* Valve packs also eliminate the chance of debris and air contamination that can happen during traditional re-valving
* Indexable base eyelets easily unbolt and reattach for mounting flexibility to achieve the best shock and canister placement
* External canister (60 psi nitrogen-charged) mounting flexibility (piggyback or remote)
* MOD Series shocks are designed for the highest performing autocross, road race, track day, and drag race competition vehicles
