The Ohlins HD751 STX 36 Blackline shock pair is a rear twin-shock setup developed for Harley-Davidson Sportster XL models. It combines a classic black finish with modern damping control to improve chassis stability and ride quality. Built as a matched pair, it is intended for riders who want more support and adjustability without changing the bike’s character.

Ohlins | Made to race, perfected to ride

Ohlins suspension is engineered with consistent damping behaviour and long-term serviceability in mind. The STX 36 Blackline family is designed to suit custom and Harley applications where appearance matters as much as control.

Who this shock is for

  • Sportster XL riders chasing a more controlled rear end for everyday road use
  • Owners updating suspension on a custom or vintage-inspired build with a black finish
  • Riders who want a tunable rear setup to suit load, roads, and personal preference

Shock design & features

  • STX 36 Blackline rear shock pair for twin-shock applications
  • Emulsion-type design (oil and gas in the same chamber)
  • Matched left/right units for rear fitment

Tuning controls

  • Spring preload adjustment
  • Rebound damping adjustment
  • Compression damping adjustment

Before you install

  • Confirm fitment for Harley-Davidson Sportster XL and rear twin-shock mounting
  • Set sag with preload first, then balance rebound and compression to suit your roads
  • Re-check all fasteners and clearances after the first ride

Serviceability/lifecycle

Like other Ohlins units, these shocks are designed to be maintained and reconditioned over time. Periodic servicing helps keep damping consistent and protects internal components as the oil and seals age.
