DNM Replacement Blue Rubber Bumper for Shock Shaft SDNM0009

Replacement blue rubber bumper designed for DNM shock shafts. This spare part fits compatible DNM rear or front shocks and functions as an impact absorber and end stop for the suspension shaft. It helps reduce metal‑on‑metal contact at the end of travel, cushions impacts, and contributes to restoring correct damping limits after wear or damage.

Advantages

The bumper is molded from durable rubber formulated for shock applications, providing elastic compression to absorb impact forces and limit shaft travel. Its blue color allows quick visual identification during maintenance. As a direct replacement part for compatible DNM shafts, it enables straightforward restoration of suspension behavior without replacing the entire shock assembly.

Suitable for

• Repairing compatible DNM front or rear shocks
• Replacing worn or damaged end stops on suspension shafts
• Servicing bikes to reduce shaft-to-body contact and protect internal components

Key specifications

• Material: rubber elastomer designed for impact absorption
• Color: blue for easy identification
• Function: bump stop / end cap to limit shaft travel and absorb impacts
• Compatibility: intended for DNM shock shafts designed to accept this style of bumper

How to use

Remove the shock from the bicycle if required by the service procedure, then disassemble according to the shock manufacturer’s instructions to access the shaft end. Slide the replacement rubber bumper onto the shaft or seat it into the designated recess, ensuring it sits flush and is oriented correctly. Reassemble the shock and test travel and damping in a controlled environment to confirm the bumper limits travel as intended and there are no abnormal noises or rubbing.

Usage recommendations

Inspect the bumper periodically for signs of cracking, hardening, or extrusion. Replace the part if any deformation or deterioration is observed. Use only compatible replacement parts and follow DNM service guidance for disassembly, reassembly, and torque settings. Dispose of the old rubber part according to local waste regulations.
