Fox Factory Race 2.5 X 18 External Bypass (3-Tube) Piggyback Shock (Custom)

The 2.5-inch diameter body of this FOX Factory Race shock, combined with its 18-inch stroke length, is built for serious off-road travel. This isn't your average bolt-on upgrade; it's a custom-tuned piece of equipment designed to handle extreme conditions and provide consistent damping performance when you need it most, whether you're hitting desert whoops or navigating rocky climbs.

At its core, this shock features a 3-tube external bypass design. This advanced system allows for a much wider range of damping adjustments compared to standard shocks. The external tubes let you fine-tune compression and rebound characteristics independently, giving you precise control over how the suspension reacts to terrain. The piggyback reservoir is also a key feature, holding extra oil to help manage heat buildup during prolonged, hard use, which is crucial for maintaining consistent performance and preventing shock fade. All the machined aluminum components are black anodized, offering a tough finish that resists corrosion and looks sharp.

Because this is a custom-tuned shock, it's intended for specific applications where precise damping and travel are paramount. While the exact tuning will depend on your vehicle and intended use, the core design is race-proven, meaning it's built to withstand incredible punishment and deliver reliable control. If you're building a high-performance off-road vehicle and need suspension that can keep up with demanding driving, this FOX shock is a well-built option.
