The Ohlins HD004 STX 36 Twin shock kit is a rear suspension solution for Harley-Davidson Sportster models using a twin-shock layout. Built around Ohlins’ STX architecture, it focuses on controlled damping and consistent response for road use. It is designed to provide a stable platform you can tune to suit load, tyres and riding conditions.

Ohlins | Made to race, perfected to ride

Ohlins twin shocks are engineered to deliver predictable behaviour through the stroke, helping the bike stay composed over bumps and during weight transfer. The STX design targets repeatable damping performance for day-to-day riding and spirited use.

Who this shock is for

Suited to Sportster riders who want more support and control from the rear end than standard twin shocks typically provide. A good match if you ride on mixed road surfaces, carry varying loads, or want adjustability to fine-tune feel and comfort.

Shock design & features

This model uses a gas-pressurised, oil/gas separated damping layout to maintain consistent damping behaviour as conditions change. The design is intended to reduce foaming and keep damping response stable during longer or harder rides.

Tuning controls

Adjustment is provided for rebound damping and compression damping, allowing you to balance chassis control with bump compliance. Spring preload adjustment is included to set ride height and support for rider weight and luggage.

Before you install

  • Confirm fitment for your exact Harley-Davidson Sportster variant and year before installation.
  • Set sag and preload first, then refine rebound and compression to suit your roads and tyre choice.
  • If your bike has been modified (wheels, tyres, guards, exhaust routing), check clearance through full suspension travel.
