CNC Springer Chain Tensioner with Chain Guide - Billet Aluminum

Keep your chain running smoothly with this Spring Loaded Chain Idler Pulley, designed to maintain consistent chain tension for improved performance and reliability. The spring-loaded design automatically adjusts as the chain moves, reducing slack, minimizing chain stress, and helping prevent chain derailment during acceleration and rough riding conditions.

Featuring a durable 10-tooth sprocket with a sealed bearing, this idler pulley delivers smooth, low-friction operation while requiring minimal maintenance. The complete kit includes all necessary mounting hardware for a quick and easy installation.

CNC Springer Chain Tensioner with Chain Guide:

• Engine Mount Spring Tensioner Assembly
• 10-tooth Sprocket
• Tension Spring
• Tensioner 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 tensioner sprocket.
