Description

Stock Harley shocks compromise handling and comfort, especially once you start pushing harder or carrying a passenger regularly. The Progressive 412 Series delivers a tunable suspension upgrade that adapts to your specific weight and riding style without requiring custom fabrication. With a straightforward five-position preload adjuster and proven durability, you'll feel the difference in control and comfort on every ride.

Key Specifications:

  • Length: 12.5"
  • Fitment: H-D Harley-Davidson models
  • Material: Chrome finish
  • Preload adjustment: Five-position cam
  • Installation: Bolt-on
  • Measurement standard: Center-of-eyelet to center-of-eyelet
  • TüV approved (refer to certificate)
  • Chain/belt guard clearance: May require spacing on 1986-2015 XL models
  • Handling impact: Slightly longer than stock—quicker steering response
  • Design philosophy: Simple, durable, cost-effective

Installation Notes: Confirm wheel travel clearance with your frame before installation. Monitor swingarm-to-exhaust and tire-to-guard contact points. Shock length variation affects head angle and steering geometry—plan accordingly for your setup.
