This genuine OEM exhaust rubber sleeve is designed to provide a secure, leak-proof seal between the expansion chamber and the silencer. It plays a critical role in maintaining exhaust pressure and reducing vibration-induced wear on your 2-stroke exhaust system.

Compatible with a wide range of 250cc and 300cc models from 2017 to 2026. This includes KTM SX, XC, EXC, and XC-W models; Husqvarna TC, TE, and TX models; and GasGas EC, EX, and MC models. It is a direct replacement for part number 55405057000.

Manufactured from high-quality, heat-resistant rubber, this coupling is built to withstand the extreme temperatures and pressures of off-road riding. Replacing a worn or cracked sleeve helps prevent power loss and keeps your engine running efficiently.
