Upgrade Chain Tensioner Roller with Spring: Adopting upgraded metal roller with a shock-absorbing spring, allowing the chain to freely adjust tension during operation, avoiding abnormal wear and breakage caused by excessive tension on the chain and sprockets and extending chain lifespan.
No Assembly Required: Our chain tensioner has been pre assembled. Easily installed using the included tools and two screws. If using this chain tensioner on a CT100U or CC100X mini bike, upgrading to a larger sprocket is required.
Strong and Durable: Made of heavy-duty metal, sturdy and wear-resistant, the smooth surface reduce chain wear, and adjust the chain tightness, and keep the chain running smoothly.
Note: This chain tensioner cannot be used simultaneously with the jackshaft kit or torque converter kit. If the chain is close to the wheel, the clutch must be mounted in reverse to keep the chain aligned straight.
