Featuring a lightweight design, an EVOL air spring, and a dual piston damper with a versatile 3-position switch, this shock is designed to enhance pedaling efficiency, absorb impacts effectively, and ensure efficient power transfer to the ground. Its advanced features, including the Genuine Kashima Coat on Factory Series models, contribute to its durability and responsiveness.

Ensure proper orientation and secure mounting of the shock to your bicycle frame. Refer to your bicycle manufacturer's specifications for torque settings and compatibility. Use appropriate mounting hardware for your frame type (e.g., metric or trunnion-style options).
The EVOL air spring requires precise air pressure for optimal performance. Use a high-pressure shock pump to inflate the main air chamber. Consult the FOX Factory website or your bike manufacturer's guide for recommended air pressure settings based on rider weight and riding style.
Sag is the amount the suspension compresses under the rider's weight. Proper sag is crucial for suspension performance. Aim for 25-30% sag for trail riding, or as recommended by your bike manufacturer.

The DPS (Dual Piston System) damper features a 3-position switch to quickly adapt the shock's performance to different riding conditions:
The rebound dial controls the speed at which the shock extends after compression. Proper rebound setting prevents the shock from "packing up" on successive bumps or "bucking" the rider. The dial typically has a range from "Fast" to "Slow".

Regular cleaning and inspection are vital for the longevity and performance of your shock.
To maintain optimal performance and prevent premature wear, regular professional servicing is recommended. Refer to the official FOX Factory service schedule for detailed intervals, typically involving:
Note: Riding in harsh conditions (e.g., wet, muddy, dusty) may require more frequent service.
