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.

Öhlins Motorcycle Suspension Warranty

New Öhlins motorcycle shock absorbers, front forks and cartridge kits supplied by Teknik Motorsport are covered by the applicable Öhlins manufacturer’s warranty against defects in materials and workmanship.

Teknik Motorsport is an authorised Öhlins Service Centre and administers warranty claims in accordance with the Öhlins warranty conditions. The service intervals below form part of the maintenance requirements for Öhlins products supplied and supported by Teknik Motorsport.

This warranty is in addition to the consumer guarantees that apply under the Australian Consumer Law.

  • Registered motorcycles — non-competition road use Five years, subject to correct application, installation, setup and servicing every: 20,000 km or two years, whichever occurs first.
  • Registered motorcycles — adventure and light off-road use Five years, subject to correct application, spring rate, setup and servicing every: 10,000 km or annually, whichever occurs first.
  • Unregistered or competition motorcycles Two years for eligible Öhlins MX and Enduro products, subject to inspection every ten hours and servicing every: 30 operating hours or annually, whichever occurs first.

Compliance with the applicable service interval is a condition of the Öhlins manufacturer’s warranty. Evidence of servicing may be required when a warranty claim is assessed.

A seal leak, loss of damping performance or internal wear arising after the prescribed service interval has been exceeded will be treated as a service or maintenance issue rather than a manufacturing defect.

Warranty repairs

Öhlins suspension products are designed to be serviced and repaired. Where a warranty claim is approved, the normal remedy is repair of the customer’s original suspension unit using genuine Öhlins replacement parts.

Replacement of a complete shock absorber, fork or cartridge kit is not automatic and would normally occur only where the product has suffered a manufacturing failure that cannot reasonably be repaired. This is at Ohlins discretion. 

Öhlins spare parts and service kits

Öhlins spare parts, seals, bushes, service kits, springs, fluids and individual components are covered only against defects present when supplied.

No fixed age-based warranty applies to wear items, service parts or consumable components. Wear, deterioration, contamination, incorrect installation and damage caused by another component are not manufacturing defects.

Öhlins gives the customer a meaningful five-year warranty on products (Units), provided the suspension is maintained as suspension should be maintained. Teknik supports that warranty locally, can inspect the product properly, and can repair it with genuine parts rather than discarding it.
