Overview

What Can the RockShox 300psi Shock Pump Do for Your Ride?

The RockShox High-Pressure Fork/Shock Pump rated to 300psi maximum is built for setting air spring pressure in suspension forks and rear shocks. Setting air pressure precisely is the single biggest factor in getting your suspension to feel right, and this pump delivers an accurate, easy-to-read gauge so you can hit your target without guesswork or over-pressurizing. Built for the standard Schrader valve found on virtually all modern air suspension components.

With a 300psi capacity, this pump covers air spring setup on forks and rear shocks that run up to 300psi. Check the recommended pressure for your fork or shock first. It is a clean, reliable tool for weekly sag checks, post-service spring setup, or dialing your spring rate between rides. Riders whose service needs include IFP pressures above 300psi should step up to RockShox's 600psi pump.

Is the 300psi pump sufficient for setting sag on my RockShox fork?

It is, as long as your fork's recommended air pressure is 300psi or less. Always check your fork specifications to confirm the correct pressure range.

What is the difference between this pump and the RockShox 600psi version?

The 300psi pump handles standard air spring setup for forks and shocks. The 600psi version is required for IFP (Internal Floating Piston) service on rear shocks and specific high-pressure fork applications like the BoXXer World Cup. If you are only doing routine spring setup, the 300psi pump is all you need.

How do I check sag with a shock pump?

Attach the pump to your fork or shock air valve, note the current pressure, then set your sag by adjusting pressure up or down. Consult your suspension manufacturer's setup guide for recommended sag percentages for your specific model.
