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.
