The QA1 MOD Series piggyback coil-over shock absorber (M511PR) provides elite-level tunability through revolutionary QuickTune Technology. Designed for right-hand installation with a bearing mount, this nitrogen-charged shock allows for rapid revalving using dry modular valve packs—changing the valving without opening the oil path or risking contamination. This design enables independent control over compression and rebound characteristics to suit specific track conditions or vehicle setups.

Engineered for versatility, the M511PR features a 11.5-inch compressed and 16.875-inch extended length. The indexable base eyelet can be unbolted and rotated to ensure optimal canister placement even in tight mounting configurations. Every unit is manufactured in QA1’s Lakeville, Minnesota facility and undergoes 100% dyno testing to ensure consistent, serialized performance.
