The Ohlins HD142 STX 36 Twin rear shock set is built for Harley-Davidson Sportster XL models needing controlled damping and consistent feel from the rear suspension. This unit uses a gas-charged design to stabilise damping behaviour during extended riding. It’s intended to provide predictable support through braking, cornering and acceleration without relying on vague, over-soft movement.

Ohlins | Made to race, perfected to ride

Ohlins suspension focuses on controlled damping and repeatable performance. The STX 36 Twin format is a proven approach for twin-shock Harley applications where chassis balance and traction matter.

Who this shock is for

Suited to Sportster XL riders who want a more composed rear end than standard, especially when pushing on through bends or carrying extra load. It’s also a solid option when you want tuning capability rather than a fixed, one-setting shock.

Shock design & features

This is a twin rear shock arrangement from the Ohlins STX 36 family. It is a gas-charged shock design to help maintain damping consistency. The architecture is aimed at delivering stable chassis behaviour and clearer feedback from the rear tyre.

Tuning controls

The HD142 provides damping adjustment for both compression and rebound, allowing you to tune how the rear reacts to bumps and how it returns after compression. It also supports spring preload adjustment to set ride height and sag to suit the bike and rider.

Before you install

  • Confirm compatibility with your Harley-Davidson Sportster XL and existing rear mounting hardware.
  • Set spring preload for correct sag before fine-tuning damping.
  • If replacing worn components, inspect rear mounts and bushes during installation.

Serviceability/lifecycle

As an Ohlins unit, this rear shock set is designed to be maintained with periodic servicing to keep damping performance consistent over time. Regular inspection for leaks and worn mounting components helps preserve ride quality.
