Progressive 990 Shocks - Harley Sportster
About Progressive
Progressive Suspension has focused exclusively on American V-twin suspension since 1982, and its Monotube fork cartridges and 400/970/970G shock series are among the most common upgrades on baggers and Softails. For most riders the stock rear shock is the single worst part on the bike — this is the fix.
Unleash the full potential of your Harley-Davidson Sportster with Progressive 990 shocks. These fully adjustable monotube rear suspension units feature high and low-speed compression damping, rebound adjustment, and tool-free preload tuning. The high-pressure design with deflective disc damping ensures consistent performance through the full stroke, providing improved stability and cornering for an exhilarating ride.
