Progressive Suspension 444 Series Shock - 13.5 Inch Heavy-Duty Black (Part Number 444-4073B)

444 Series Shock - 13.5" - Heavy-Duty - Black

Experience enhanced ride quality with the Progressive Suspension 444 Series Shock, designed specifically for demanding motorcycle applications. This shock absorber features innovative Frequency Sensing Technology (FST) that detects the frequency of bumps and automatically adjusts damping for a smoother, more controlled ride. The inclusion of deflective disc valving ensures precise damping characteristics, providing stability and comfort across various terrains. The shock's pre-load spring can be easily adjusted by hand without special tools, allowing for quick customization to suit rider weight and riding style. Each shock is equipped with a progressive-rate spring and is high-pressure gas charged, ensuring consistent performance and durability under heavy loads.
Constructed in the USA, these shocks are slightly longer than stock units, which may alter the head angle and result in quicker steering response. Conversely, shorter shocks can modify the steering to be slower, offering flexibility for different handling preferences. Before installation, verify that wheel travel can be safely adjusted without clearance issues such as contact with exhaust components, swingarm, or chain/belt guards. These shocks are recommended for heavy-duty applications, especially for bikes frequently operating at or near maximum load capacity over half the time, providing the strength and reliability needed for rigorous use.
