SKU: HD 503

Sale price$1,494.95 CAD


A well-proven monotube design, the Öhlins STX 46 shock absorber sets the standard for performance, quality, and durability for your 18+ Softails. It is a major suspension upgrade from stock suspension. It features a large 46mm main piston, an internal gas reservoir within the main body of the shock, length adjustability, and a hydraulic preload adjuster.

With adjustable damping, you can change the behavior of the shock to suit your taste. This shock features a length adjuster that allows for a ride height change without compromising suspension travel. The hydraulic preload is the highlighted feature of this shock – allowing you to make preload changes without a tool to accommodate weight variations.
