RockShox emphatically suggests using the specified fluid in your RockShox product. RockShox and SRAM specified fluid and lubricants are tested to ensure they have the correct compatibility with our parts. Non-SRAM/RockShox fluids and lubricants can cause shrinking or swelling of parts resulting in leaks or excessive premature wear. SRAM cannot ensure the quality and compatibility of any fluids or lubricants that are not designed in partnership with the product itself, forcing us to ask that customers only use our specified products.
Enter your serial number at the RockShox Trailhead App for links to relevant service documents, or consult our Oil, Air, Coil, Tokens and Specifications for oil weights and volumes found on the SRAM Service Site.
