If your chain is making a popping / clicking noise or sounds like it is binding when it runs, not running as quiet as it once did , the chain is worn/stretched beyond it's service limit and ready to fail. Order replacements now to have on hand for the inevitable.

  Please measure and verify the actual # of links or the overall length of your drive chain before ordering. 
  If the chain you need is longer or shorter, contact us, we will make one especially for you.
