Progressive Suspension 990 Series Piggyback Shocks - 13.5 Inch, Black | Part 990-1011

The Progressive Suspension 990 Series Piggyback Shocks are engineered for high-performance motorcycle handling and ride comfort. Featuring a high-pressure gas monotube design, these shocks provide consistent damping and durability for demanding riding conditions. The adjustable compression damping knobs allow riders to fine-tune the high-speed and low-speed compression for optimized control and comfort. The 0.4-inch adjustable height eyelet offers flexibility for customizing the ride height, which can influence steering response and overall handling. The aluminum body ensures lightweight strength and corrosion resistance, while the deflective disc damping technology contributes to smooth suspension movement. A captured jounce bumper provides controlled bottoming, enhancing rider confidence during aggressive riding or harsh terrain. The piggyback reservoir improves heat dissipation during extended use, maintaining consistent performance over time. Each shock features a linear rate coil spring that offers predictable ride characteristics, and the overall design is manufactured in the USA to meet high-quality standards. These shocks are measured center-of-eyelet to center-of-eyelet, ensuring precise fitment for compatible motorcycle models. It’s important to verify that the overall length aligns with OEM specifications to avoid issues with wheel clearance, swingarm, or exhaust contact. Slight adjustments in shock length can slightly alter steering geometry, affecting handling dynamics. Proper installation and compatibility checks are recommended to ensure optimal performance and safety. Whether replacing worn shocks or upgrading for better handling, the Progressive Suspension 990 Series offers a reliable, high-quality solution for serious riders seeking improved ride quality and control.
