## Long description

Replacement red coil spring DNM USD 180 SDNM0045 is designed for inverted (USD) front suspension forks. This spring provides preload and spring rate support for tuning fork travel and adjusting ride height. It is intended for maintenance, repair or upgrade of compatible USD forks specified to use a 180-rated spring, and helps restore correct suspension performance when the original spring is worn or when different preload characteristics are required.
Advantages
The coil spring offers consistent elastic properties and a uniform red finish for easy identification during service. It supports precise preload adjustment and contributes to predictable fork behavior under varying loads. Manufactured to match the dimensional and mechanical requirements typical of inverted fork spring systems, it simplifies replacement tasks and reduces the need for custom modifications.
Suitable for
Maintenance and replacement of worn or damaged USD front fork springs
Upgrading suspension preload or spring rate to alter ride height and feel
Workshop repairs where the fork manufacturer specifies a 180-rated spring
Home mechanics tuning fork performance for specific rider weight or riding style
Key specifications
Spring type: coil spring for inverted (USD) front forks
Rating: 180 (spring rate category used for preload and travel control)
Color: red (for visual identification)
Application: front suspension forks with compatible internal diameter and mounting for coil springs
Function: provides preload and contributes to overall spring rate of the fork
How to use
Install the spring according to the fork manufacturer’s service instructions. Typical installation involves removing the fork lower leg or top cap as required, inserting the spring into the appropriate fork leg with the correct orientation, and setting initial preload using the recommended spacer or cap adjustments. After installation, perform sag and rebound checks and fine-tune preload or spacer configuration to achieve the desired ride height and travel response. Ensure all fasteners and seals are reassembled to specified torque values and check for proper function before riding.
Usage recommendations
Use this spring only in forks intended for a 180-rated coil and where internal dimensions match the spring. Verify compatibility with your fork model and follow manufacturer service manuals for disassembly, installation, and torque settings. If unsure about fit or setup, consult a qualified mechanic to ensure safe and correct suspension performance.
