Description

The FOX Factory Series 2-inch bump stop, model 981-20-040, is engineered for high-performance off-road and racing applications. Designed with a robust 2.5-inch aluminum body, this bump stop offers exceptional durability and shock absorption in extreme conditions. Featuring FOX’s patented internal bypass technology, it delivers a smooth and controlled damping experience, whether you’re navigating rocky climbs or high-speed desert crossings. The incorporation of FOX’s ride zone technology, which combines a race-developed piston, internal bypass, and dual speed compression adjustability, allows precise tuning to match terrain, vehicle weight, and driving style. This ensures optimal suspension performance in demanding environments, giving drivers confidence and control over challenging terrains.

Constructed with high-quality materials such as CNC-machined aluminum components with a black anodized finish and a hard chrome plated 4130 chromoly steel shaft, this bump stop is built to withstand the harshest conditions. The proprietary Cerakote® ceramic coating adds an extra layer of protection over the zinc-plated basecoat, enhancing corrosion resistance and longevity. The JM92 MIL-SPEC oil, formulated specifically for off-road racing, ensures reliable damping performance under extreme temperatures and vibration.

This product is owner serviceable and rebuildable, allowing for easy maintenance and customization. It features redundant seals on the 7/8-inch shaft to prevent dirt ingress and maintain consistent performance. Whether upgrading an existing suspension or building a custom off-road setup, the FOX Factory Series bump stop delivers the strength, adjustability, and reliability needed to dominate any terrain. Its versatile design and premium construction make it suitable for a wide range of off-road vehicles and racing applications, ensuring consistent performance mile after mile.
