Progressive 412 Series Shocks - Harley-Davidson
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.
The Progressive 412 Series Shocks deliver reliable and consistent damping performance for your Harley-Davidson, all within an accessible budget. Their robust double-wall steel construction ensures durability for the long haul.

Common questions
Can I adjust the preload myself?
Yes, the 5-position cam-style adjuster requires no special tools. You can easily turn it to dial in your preferred ride height and stiffness to match your riding style and load.
What's the difference between standard and heavy-duty springs?
Standard springs are suitable for most riders and typical riding conditions. Heavy-duty springs are recommended for riders who frequently carry a passenger, heavy luggage, or prefer a firmer, more aggressive feel in their suspension.
Will these shocks fit my specific Harley-Davidson model?
Progressive 412 Series shocks are available for many Harley-Davidson motorcycles. Please verify your specific model and year using our Shop by Bike tool before ordering to ensure correct fitment and optimal performance.
