RockShox Lower Leg

Compatibility is determined by matching the stanchion diameter, wheel size, and axle type. This specific part is designed for forks with 35mm stanchions, 27.5-inch wheels, and a 15mm axle. Always verify your current fork's model year and specific part number against the manufacturer's spare parts catalog to ensure a perfect match.

Replacing lower legs is a standard maintenance procedure, but it does require specific tools like a mallet, socket set, and fresh suspension fluid. If you are comfortable performing a basic lower leg service, you can likely handle this installation. However, if you are unsure about the process or lack the necessary tools, a professional mechanic is recommended to ensure the seals are seated correctly and the fork functions safely.

This assembly typically includes the lower legs with the bushings pre-installed. It is standard practice to install new wiper seals and foam rings whenever you replace the lower legs to ensure the best performance and longevity for your suspension.

You should consider replacing the lower legs if the bushings have developed excessive play that cannot be fixed, or if the magnesium casting has sustained structural damage like cracks or stripped axle threads. If your fork is simply feeling sluggish, a standard service with new oil and seals is usually sufficient, but physical damage to the lowers requires a full replacement.

Yes, this is a direct factory replacement designed to house your existing internal components. As long as your fork model matches the specifications for this part number, your damper and air spring assembly will fit directly into these new lower legs.
