The Ohlins HD817 STX 36 Twin rear shock set is built for Harley-Davidson Dyna FXD models that use twin rear dampers. It uses a gas-pressurised damping system to maintain consistent control as conditions change. Designed as a rear twin-shock solution, it supports accurate tuning for ride quality and stability.
Ohlins suspension is engineered around controlled damping and clear feedback to the rider. The HD817 follows that approach with an STX 36 Twin architecture suited to Harley-Davidson twin-shock rear ends.
Ideal for Dyna FXD riders who want more disciplined damping control than standard suspension and the ability to tune the rear end to their riding style. It suits road riding where stability, traction and consistency matter.
This is a gas-pressurised twin rear shock arrangement for the rear of the bike. The pressurised design helps reduce fade and supports stable damping behaviour across varying loads and road conditions.
The HD817 provides rebound adjustment, allowing you to tailor how quickly the rear suspension returns after a bump or weight transfer. This helps balance comfort, grip and chassis control depending on your setup.
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.
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.
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, 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.
