It also fits the broader SLX family where the same clutch tensioner arrangement is installed.
Features

- Commonly used across SLX 100, 200, 300, 400 and Spectrum applications

Compliance and Safety
Isolate the unit before service, then inspect the belt, pulley alignment and mounting hardware at the same time. If the old tensioner shows side wear, noise or free play, replace related worn drive components as needed because a new tensioner will not correct a damaged belt path on its own.
