Fox Harley-Davidson AM M8 Softail STD Spring [13.5/2.5] 2.0 IFP-QSR Hydro Preload Adjust Kit - Rear

Upgrade the rear suspension performance of your Harley-Davidson M8 Softail with the FOX Powersports 897-27-604 shock and hydraulic preload adjuster kit. Designed for riders seeking improved control, ride consistency, and adjustability, this rear shock assembly features FOX’s 2.0 Internal Floating Piston (IFP) technology and a remote hydraulic preload adjustment system. It is configured for the standard 13.5-inch shock application with a 2.5-inch spring.

The 2.0 IFP design helps separate shock oil from pressurized nitrogen, reducing aeration and maintaining consistent damping performance during demanding street and touring use. The hydraulic preload adjuster allows convenient adjustment for passenger weight, luggage, or changing riding conditions without requiring direct access to the spring collar. This makes it easier to maintain a balanced ride height and controlled suspension response when load conditions vary.

Built for the rear suspension of compatible Harley-Davidson M8 Softail models, the FOX 897-27-604 combines application-specific fitment with FOX Powersports engineering. The kit includes one rear shock assembly and is intended for installation as a replacement or performance upgrade. Verify the motorcycle model, year, suspension configuration, and required mounting hardware before ordering.
