Recommendations and Warnings
Cane Creek recommends only trained suspension technicians perform service on all suspension, using all required tools and following all proper procedures. Anyone without access to the proper equipment or with any concerns on the procedures should defer to an authorized Cane Creek service center for service. Improper service can result in loss of performance or suspension failure. All Cane Creek shocks have pressurized nitrogen and oil, even coil shocks. Follow the service procedures exactly as written to avoid possible injury or harm to the suspension. Always wear eye protection while performing suspension service.
Please dispose of all waste products and materials through proper channels to avoid contamination of the environment.
Any damage or issues resulting from improper service will not be covered by warranty. If you have a shock still in its original warranty period and do not wish to void your warranty, please contact an authorized Cane Creek service center.
These service instructions cover the basic service procedures using standard service kits. If your suspension requires parts beyond standard replacement parts – shaft, damper tubes, end eyes – please consult your authorized Cane Creek service center or contact us at our Cane Creek Support Center.
Service Notes
The Air IL and Coil IL as well as the Standard and Trunnion variants of both share many service steps. Some images in these instructions may not be identical to the valve body or outer damper tube on the Air IL Standard, but that is only when the process is the same for the shock in the image and the shock on your bench.
