Performance Black Engine Mounted Chain Tensioner with Spring

Using an engine-mounted spring tensioner helps keep your chain running smoothly with less jumping and less chance of derailment and it can cut down on vibration. This kit mounts directly onto the engine and is easily installed.

• Engine mount assembly
• Pulley
• Tension spring
• Mounting hardware

Note: 415 engine drive chain length may need to be shortened to achieve proper tension, our 415 Chain Breaker (Item # ENGJL-415CB) is recommended. Due to a conflict with the seat post tube engine mounting hardware, it is not recommended to use the innermost adjustment hole for the tensioner sprocket.
