QA1 M911PR Mod Series Shock, Piggyback Canister, 14 Inch Spring

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 transform the way racers respond to changing track conditions and configurations. Instead of limiting racers to basic adjustments, MOD™ Series shocks can be completely revalved in minutes while remaining on the car, saving racers time and money.

Features QuickTune™ technology – modular valve packs that allow for completely revalving the shock without even having to remove it from the car!
Medium compression and rebound valve packs standard
Soft or firm compression and rebound valve packs also available
24 click independent compression and rebound adjustment with low-speed bleed
Large solid piston (with blow-off valve)—improved driver feel and control with up to 1,600 lb. force
High-speed valving adjustment (coarse adjustment)—relates to shock operation during impact events, like hitting a pothole or curb
Low-speed valving (fine-tune adjustments)—adjusts ride quality and weight transfer on corner entry/exit; more bleed for softer feel and less bleed for stiffer feel
Indexable base eyelet—multiple mounting position to optimize knob access and provide more mounting flexibility
Piggyback or remote canister options
Thrust bearings included
American made
