Product Description

The FOX 897-27-309 rear shock set is a premium upgrade for 2018-2026 Harley-Davidson Softail motorcycles, delivering enhanced ride comfort, control, and stability. With a gas-charged mono-tube and Internal Floating Piston (IFP), the shock maintains consistent damping regardless of ride length or load - preventing fade and preserving smooth suspension action across miles. The 3-position Quick Switch Rebound (QSR) allows riders to fine-tune rebound behavior depending on conditions: softer for comfort on bumpy or urban roads, firmer for control under load or spirited riding, or balanced for everyday riding.

Constructed with a large-diameter anodized aluminum body and a low-friction hard-chrome shaft, the 897-27-309 keeps unsprung weight manageable while offering rugged durability for long-term use. The preload-adjustable coil spring with a 13.5" extended length raises the rear end - improving suspension travel, cornering stability, and ride comfort on rough roads or with extra load. Bolt-on installation using stock eyelet mounts makes it accessible for most Softail owners. Fully rebuildable and serviceable, this shock set is ideal for those wanting long-lasting performance, comfortable touring, and confident handling on a variety of road conditions.
