The Ohlins HD516 STX 46 Custom & Heritage rear shock absorber is built for Harley-Davidson Softail models where comfort, stability and consistent damping matter. It combines classic-looking finishes with modern internal design to sharpen control without losing the character of a cruiser. Adjustment range is provided so the suspension can be matched to rider load and typical road conditions.

Ohlins | Made to race, perfected to ride

Ohlins suspension focuses on controlled damping and repeatable setup, giving riders a clear path to improving ride quality through correct adjustment rather than guesswork. The HD516 is part of the STX 46 Custom & Heritage family and is designed to suit custom and heritage-focused Harley-Davidson applications.

Who this shock is for

  • Softail riders wanting a more settled ride over rough roads and varying surfaces
  • Owners carrying a passenger or luggage who need to reset preload and damping for the extra load
  • Custom and heritage builds where appearance matters as much as function

Shock design & features

  • Rear mono shock design for Harley-Davidson Softail fitment
  • STX 46 Custom & Heritage architecture aimed at improved damping control and ride comfort
  • Oil and gas separated design for more consistent damping during use

Tuning controls

  • Rebound damping adjustment to control how quickly the shock extends after a bump
  • Compression damping adjustment to manage how the shock absorbs impacts and weight transfer
  • Spring preload adjustment to set ride height and support for rider/passenger load

Before you install

  • Confirm model compatibility for Harley-Davidson Softail Heritage Classic and Softail Low Rider ST
  • This unit replaces HD 505 (as noted for this part)
  • After installation, set sag and then fine-tune rebound and compression to suit your typical riding

Serviceability/lifecycle

Ohlins shocks are designed to be serviced, allowing oil and wear components to be refreshed to keep damping consistent over time. Routine servicing is recommended as part of long-term ownership, particularly if the bike is used regularly or loaded.
