The Ohlins HD144 STX 36 Twin shock kit is built for Harley-Davidson Sportster XL models that need more controlled rear suspension response. Based on Ohlins STX architecture, it focuses on stability, traction and consistent damping across varied road conditions. Supplied as a rear twin-shock setup, it is designed to give clearer chassis feedback and tunability than a basic replacement unit.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed from competition experience and refined for real-world use. The HD144 carries that approach into a twin-shock layout suited to the Sportster platform, with an emphasis on predictable behaviour and repeatable setup.

Who this shock is for

  • Sportster XL riders wanting improved composure under braking and through corners
  • Riders who value adjustability to suit load, road conditions and riding style
  • Owners upgrading worn or inconsistent rear suspension with a matched twin-shock package

Shock design & features

This is a gas-pressurised, oil/gas separated design intended to maintain damping consistency. The STX 36 Twin format suits twin rear shock applications and is aimed at providing stable chassis support with improved traction feel.

Tuning controls

The HD144 provides external rebound damping adjustment and external compression damping adjustment, along with spring preload adjustment. These controls let you balance comfort, grip and chassis support to match your riding and typical load.

Before you install

  • Confirm fitment for your exact Harley-Davidson Sportster XL model and year
  • Set sag and preload correctly before making damping changes
  • Make one change at a time and record your settings so you can return to a known baseline
