PROX Lower Shock Bearing Kit for KTM EXC, EXCF, XCW 125, 150, 250, 300, 350, 450, 500 2017-2025

The PROX 26.450077 shock bearing kit is designed for KTM EXC 150, EXC 250, EXC 300, EXCF 250, EXCF 350, EXCF 450, EXCF 500, XCW 125, XCW 150 from 2017 to 2025. The shock is mounted at both ends on bearings or spherical bearings. Seized or worn, they create play and hold the shock back: the rear end becomes harsh and the suspension loses its sensitivity.

Specifications

• Brand: PROX
• Manufacturer part number: 26.450077

When to replace it?

• Play at the rear when you lift the wheel.
• Spherical bearing or bearing that binds, clunking noise at the rear.
• Rusty bearing or marked sleeve at disassembly.

Check these bearings every time you remove the shock and at the same time as the linkage. Check whether it is the upper or the lower mount (given in the name).

Fitting tips

1. Remove the shock as per the manual.
2. Press out the old bearing or spherical bearing and clean the mounting eye.
3. Press in the new bearing, with the seals and sleeves packed with waterproof grease.
4. Refit the shock and tighten the pivot bolts to the manual's torque.
