What is the benefit of the Internal Bypass design?

The internal bypass design allows for more sophisticated damping control. It routes oil flow internally, providing position-sensitive damping that can offer a softer feel in the initial travel and firmer damping as the shock compresses, improving control over rough terrain.

How does the DSC adjuster work?

The DSC (Dual Speed Compression) adjuster allows you to independently tune the high-speed and low-speed compression damping. This lets you dial in the shock's response for different conditions, like softening it for washboard roads or firming it up for large impacts.

Can I rebuild this shock myself?

Yes, this FOX Factory Series shock is designed to be owner serviceable and rebuildable. This means you can perform maintenance and rebuilds yourself, helping to ensure consistent performance over the life of the shock.

Product Details

When you're pushing your vehicle to its limits off-road, whether it's hitting jumps in the desert or navigating challenging rock climbs, having suspension that can keep up is crucial. This FOX Factory Series 2.5 x 16 Internal Bypass Piggyback Shock is built to handle that kind of punishment and deliver consistent, reliable performance when you need it most.

This shock absorber is designed with race-winning technology, featuring an internal bypass system that allows for more precise damping control. The 2.5-inch diameter body houses a 16-inch stroke, providing ample travel for aggressive off-road use. The piggyback reservoir holds extra oil and helps keep temperatures down during extended runs, while the DSC (Dual Speed Compression) adjuster lets you fine-tune your compression damping for different terrain and driving styles. It's built with a tough 17-4 H900 stainless steel shaft and CNC-machined aluminum components, all protected by a new proprietary Cerakote ceramic coating over a zinc-plated basecoat for excellent corrosion resistance. The JM92 MIL-SPEC oil is specifically formulated for the demands of off-road racing.

This shock is also owner serviceable and rebuildable, meaning you can maintain its performance over the long haul. Custom valving options are available if you need to tailor the damping even further to your specific vehicle and driving needs. This is a serious piece of suspension hardware designed for those who demand the best performance from their off-road vehicle.
