FAQs
Is the coil spring included with this shock?
No, the coil spring must be purchased separately based on your weight and riding style.
Can I use this shock on any mountain bike?
It is compatible with frames designed for the specific eye-to-eye and stroke length of the model you purchased. Always verify your frame's shock requirements.
How do I adjust the low-speed compression?
Use the tool-free dial on the reservoir to select one of the 12 positions for your desired damping support.
What is the purpose of the 2-position lever?
The lever allows you to switch between 'Open' for descending and 'Firm' for climbing efficiency.
How often should I service this shock?
Service intervals depend on riding intensity, but a standard full-service is recommended annually or every 125 hours of use.
Troubleshooting
Shock feels too harsh at the end of the stroke
Ensure you are using the correct spring rate; if the spring is correct, the MCU bumper is working as intended to prevent harsh bottom-outs.
Excessive pedal bob while climbing
Engage the 2-position firm mode lever and ensure the low-speed compression adjuster is set to a higher damping value.
Noisy rebound performance
Check that the rebound adjuster is fully seated and the shock is free of trapped air bubbles; consult a suspension technician if noise persists.

Setup, Compatibility & Care
Spring Selection: Ensure you purchase a compatible spring (sold separately) based on your weight and frame leverage ratio.
Installation: Secure the shock using the correct mounting hardware for your specific frame model.
Sag Setting: Use the preload collar to set sag. Do not exceed the maximum number of turns recommended in your frame's manual.
Compression Tuning: Start in the middle position (6 clicks) and adjust based on trail feel.
Maintenance: Keep the shock body clean of grit. Inspect the damper regularly for oil leaks and ensure the preload collar detents are clean and debris-free.
