The Ohlins STX 46 Custom & Heritage rear shock is designed to improve control and ride quality on Harley-Davidson cruiser and custom platforms while maintaining a classic look. It uses a modern damping layout suited to real-world road riding where stability and comfort matter. Adjustment options let you tailor the feel to your load, roads and riding preference.

Ohlins | Made to race, perfected to ride

Built around Ohlins road suspension know-how, this unit targets predictable damping and consistent response over varying surfaces. It suits riders who want a functional handling upgrade without changing the character of a heritage-style build.

Who this shock is for

  • Harley-Davidson riders upgrading a custom or heritage build who want improved stability and comfort
  • Owners who carry a passenger or luggage and need setup flexibility
  • Riders chasing a controlled, settled feel on mixed road surfaces

Shock design & features

This is a monotube design with oil and gas separated for stable damping behaviour during longer rides and repeated hits. The layout is intended to reduce fade and keep response consistent as conditions change.

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment
  • Spring preload adjustment

Before you install

  • Confirm fitment for your exact model and any chassis or exhaust modifications
  • Set static and rider sag before fine-tuning damping
  • Record your baseline settings so changes are easy to track
