Additional benefits and features of QA1 MOD Series shocks:
* All new design delivers force, control, and unmatched tenability
* Hard anodized aluminum bodies with PTFE—durable, non-galling surface
* Double-adjustable shocks with low-speed bleed adjustments
* 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
* 24 clicks/settings—wider range of adjustment than comparable shocks
* Indexable base eyelet—multiple mounting position to optimize knob access and provide more mounting flexibility
* 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
* Piggyback or remote canister options
* Unique spring adjuster nut and tool
* Thrust bearings included
* Superior thermal performance, as oil is in constant contact with outer body
* One base shock can be upgraded over time to keep up with increased performance levels of your vehicle
