The Ohlins HD502 STX 46 Custom & Heritage rear shock absorber is built for Harley-Davidson Softail models that need improved control without losing classic styling. It uses an oil/gas separated design to maintain consistent damping over varying road conditions. With external adjustments for rebound, compression and spring preload, it can be tuned to suit rider preference and load.

Ohlins | Made to race, perfected to ride

Ohlins suspension focuses on predictable damping behaviour and clear adjustment response. The Custom & Heritage range is intended to complement cruiser and custom builds while delivering modern suspension performance.

Who this shock is for

Suited to riders of Harley-Davidson Softail Deluxe, Softail Low Rider, Softail Low Rider S, Softail Slim and Softail models who want a more controlled ride and the ability to tailor suspension feel. It also suits custom builds where appearance matters alongside function.

Shock design & features

This is an STX 46 Custom & Heritage rear shock with a separated oil/gas layout. The architecture is designed to support stable damping performance and improved ride control compared with basic, non-adjustable units, while keeping finishes appropriate for heritage-style motorcycles.

Tuning controls

  • Rebound damping adjustment to manage how quickly the shock extends after a bump.
  • Compression damping adjustment to control resistance as the shock compresses under load.
  • Spring preload adjustment to set ride height and support for rider weight, accessories and luggage.

Before you install

Confirm fitment for your exact Softail variant and any modified chassis or exhaust components. This model is noted as replaced by HD 504, which may matter for availability and parts support planning.

Serviceability/lifecycle

Like other Ohlins units, the HD502 is intended to be maintained rather than treated as disposable. Periodic servicing helps keep damping performance consistent over the long term and supports reliability for regular road use.
