Fox Racing IFP Threaded Style Air Bump Stops 2" Body 2.55" Stroke 1-1/4" Shaft Without Canister
883-02-129 Overview
Inspired by it's off-road racing predecessors, the new Factory Series bump stop combines race proven technology with new, cutting-edge features to provide increased damping performance and bottom out control in the last few inches of suspension travel.
The threaded body allows you to adjust the mounting height to fine-tune when the bump stop engages during up travel, preventing harsh bottom outs. An Internal Floating Piston (IFP) in the shaft separates the oil and nitrogen to prevent cavitation and bucking while the negative coil spring softens initial impacts and harsh top outs. The integrated FOX AIR VALVE (FAV) is located at the bottom of the shaft for easy access and is protected by the replaceable strike pad.
Factory Series bump stops allow you to use every inch of suspension travel without harsh bottoming.
