Product Description

The FOX 981-20-043 Factory Race 2.0 bump stop is a high-performance suspension accessory designed to enhance bottom-out control and extend usable suspension travel on off-road vehicles. With a 2.0" body and 4.0" travel, this hydraulic bump stop uses race-proven technology - including an Internal Floating Piston (IFP) and tunable velocity-sensitive valving - to deliver smooth damping and predictable engagement in the final inches of travel.

Constructed with a hard chrome plated chromoly shaft and CNC-machined aluminum components, this bump stop offers durability and serviceability in demanding conditions. The pinch-mount design allows installers to fine-tune bump stop engagement height using a compatible bracket or custom mount, making it suitable for off-road builds and custom suspension applications where maximizing travel and controlling harsh bottom-outs are priorities.
