The modular valve packs for MOD Series shocks are part of the compression and rebound knobs of the shock and determine the actual valving of the shock. By simply unscrewing the knobs to remove the existing ones and then screwing in new ones, the valve packs can be swapped out in just minutes, with the shocks remaining on the car, to achieve different force curves. The shock remains free from contamination with no interruption to the oil pathways thanks to QuickTune Technology. Never before could you change the valving characteristics this much without completely disassembling the shock.
