The Ohlins STX 46 Custom & Heritage rear shock for Harley-Davidson Softail models is built to improve control and ride quality while respecting the feel of a cruiser chassis. It uses a modern internal damping design paired with finishes that suit classic and custom builds. Adjustment is provided so you can tailor comfort and stability to your load and riding conditions.

Ohlins | Made to race, perfected to ride

Developed from Ohlins suspension know-how, the Custom & Heritage range is aimed at riders who want refined damping without losing the character of their bike. This unit is intended for Harley-Davidson Softail fitments listed in the product name.

Shock design & features

This is a mono rear shock from the Ohlins STX 46 Custom & Heritage family. The damping architecture is based around a separated oil and gas design to keep damping behaviour consistent over a ride.

Tuning controls

Adjustability includes rebound damping, compression damping, and spring preload. These controls let you balance comfort and support, fine-tune chassis stability, and accommodate changes in rider weight or luggage.

Before you install

Confirm correct fitment for your exact Softail model and any existing modifications. If this unit is being fitted in place of an earlier shock (noted as replacing HD 503), check mounting hardware and clearances during installation.

Serviceability/lifecycle

Ohlins shocks are designed to be maintained over time. Regular servicing helps keep damping performance consistent and supports long-term reliability.
