The Progressive Suspension 990 Series Shocks with Remote Reservoir, part number 990-2004, are designed to enhance your motorcycle's ride quality and handling. Featuring a high-pressure gas monotube design, these shocks provide consistent damping performance and improved stability on the road or trail. The aluminum body construction ensures durability and lightweight performance, ideal for heavy-duty applications where reliability is critical.
Equipped with easily accessible adjustment knobs for high- and low-speed compression damping, riders can fine-tune the suspension to match riding conditions and personal preferences. The 0.4-inch adjustable height eyelet allows for precise ride height adjustments, helping to optimize handling and clearance. These shocks incorporate a captured jounce bumper for smooth and controlled bottoming, reducing impact harshness and increasing comfort during aggressive riding.
The linear rate coil spring ensures predictable suspension behavior, while the deflective disc damping provides refined control over shock movement. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility and proper fitment. Sold in pairs, these shocks are suitable for heavy-duty applications, especially on bikes that frequently operate near maximum load ratings.
Made in the U.S.A., the 990 Series shocks are designed to slightly alter the stock length, which can result in a marginal change in head angle and quicker steering response. Before installation, verify that your wheel travel can accommodate a longer shock without clearance issues such as swingarm, axle, exhaust contact, or interference with the chain or belt guard. These shocks are an excellent upgrade for riders seeking improved handling, ride comfort, and durability in challenging riding conditions.
