Shock 9in IMCA Dry Kit 3 Port Linear / Digressive

The Shock 9in IMCA Dry Kit 3 Port Linear / Digressive (model 84-9-6P-D) is a specialized monotube shock absorber designed for IMCA-sanctioned short-track racing and dirt oval competition. This 9-inch stroke shock is engineered for racers who demand precise damping control across variable track conditions, ensuring optimal performance whether on dry slick or rough surfaces.

Featuring a three-port linear/digressive valve design, this shock provides predictable resistance that transitions smoothly from a softer initial response to firmer mid-stroke and high-speed compression. The digressive curve is particularly beneficial in dirt racing, as it absorbs initial bump impacts without bottoming out, while ramping up resistance to control chassis roll and pitch during hard cornering and acceleration. Constructed from durable steel with a blue paint finish, the shock measures 3.25 inches in outer diameter.

This shock is best suited for drivers competing in IMCA-approved racing series, including modified, street stock, and hobby stock classes, where suspension geometry and damping tuning are crucial for achieving consistent lap times and enhancing driver confidence.
