RockShox Monarch/Deluxe IFP Height Tool

The Internal Floating Piston (IFP) depth must be set to an exact measurement to separate the oil and air chambers correctly. Without this tool, it is nearly impossible to achieve the factory-specified depth, which can lead to inconsistent damping and poor shock performance.

No, this tool is specifically engineered for Monarch and Deluxe rear shock models. It will not work with other RockShox suspension units like the Super Deluxe or older coil shocks, so verify your shock model before purchasing.

Yes, while this tool is critical for the IFP depth, a full rebuild typically requires a shock pump, seal kits, suspension fluid, and potentially a vice block to hold the shock body securely without damaging it. This tool is just one piece of the puzzle for a complete service.

While you might be tempted to use a caliper, the IFP depth tool is designed to seat perfectly within the shock body and provide a repeatable, accurate measurement that is difficult to replicate with standard measuring tools. Using the correct tool eliminates guesswork and prevents potential damage to the internal components.

If you are comfortable performing basic suspension maintenance, this tool makes the process much more manageable. However, rebuilding a rear shock is an intermediate-to-advanced task; ensure you have the correct service manual for your specific shock model before beginning.
