The Ohlins HD143 is an STX 36 twin rear shock kit designed for Harley-Davidson Sportster XL models. Built around a pressurised damping layout, it delivers consistent control as conditions and loads change. This set is aimed at riders wanting more support and clearer feedback than a basic twin-shock setup.

Ohlins | Made to race, perfected to ride

Ohlins road and custom applications draw on proven damping architecture and careful valving control. The focus is predictable response, repeatability and a broad tuning range for real-world riding.

Who this shock is for

  • Sportster XL riders upgrading the rear end for improved chassis control and stability
  • Riders who want tuning capability to suit different roads, pace and load
  • Owners seeking a matched twin-shock solution from the Ohlins STX 36 family

Shock design & features

This is an oil/gas separated, pressurised twin-shock arrangement rather than an emulsion design. The pressurised layout helps maintain damping consistency and reduces the tendency for fade during extended riding.

Tuning controls

The HD143 provides rebound damping adjustment and compression damping adjustment, allowing you to balance support, comfort and grip for your riding conditions. Adjustability also helps when changing tyres, load, or overall ride feel.

Before you install

  • Confirm fitment to your specific Harley-Davidson Sportster XL model and any accessories that may affect clearance.
  • Set sag and verify both shocks are adjusted evenly side-to-side before fine-tuning.
  • If your motorcycle has been modified (ride height, exhaust, guards), check for interference through full suspension travel.

Serviceability/lifecycle

As an Ohlins unit, the shocks are designed to be maintained with periodic servicing to keep damping performance consistent over time. Routine inspection for leaks, bushing wear and spring condition helps protect long-term ride quality.
