The Ohlins HD538 STX 36 Twin shock package is a rear suspension solution for Harley-Davidson FL Touring models including Road King, Street Glide and Electra Glide. Built around Ohlins twin-shock architecture, it focuses on consistent damping control and a planted feel over varying road surfaces. This unit is suited to riders who want more composure and tunability from the rear of the bike.

Ohlins | Made to race, perfected to ride

Ohlins suspension is designed to provide controlled movement through the stroke, helping the tyre stay in contact with the road and keeping the chassis settled. The HD538 is part of the STX 36 Twin family, developed for Harley-Davidson touring applications where stability and comfort both matter.

Who this shock is for

Designed for Harley-Davidson FL Touring motorcycles using a rear twin-shock layout. It suits riders who carry varying loads, ride longer distances, or want more control and feel from the rear suspension without changing the bike’s character.

Shock design & features

This is an emulsion-type shock design, where oil and gas share the same working volume. The STX 36 Twin format supports predictable damping behaviour and a durable, serviceable construction intended for real-world road use on heavier touring platforms.

Tuning controls

This model provides rebound damping adjustment. Rebound control lets you manage how quickly the rear suspension extends after bumps and load changes, helping maintain stability and traction across different road conditions.

Before you install

Confirm fitment for your exact FL Touring model and any accessories that may affect clearance or load. After installation, set rider sag and then fine-tune rebound to match your typical riding conditions and payload.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced to maintain performance over time. Periodic oil and seal maintenance helps keep damping consistent, especially on bikes that see frequent kilometres or heavier loading.

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.
