This Spring Auto Spring Bearing Idler Chain Tensioner needs no adjustments. It features a heavy duty spring to keep constant chain tension. No longer do you have to keep adjusting your idler to compensate for your chain stretching out.
With a heavy duty spring, your chain is locked in place offering better alignment and constant tension. The bracket is thicker steel and a more sturdy design so that your chain is less stressed and can drastically extend the life of your chain.
It can reduce stress on the chain, maintain consistent pressure, and maximize performance.
