How many times have you heard. “The timing chain has jumped a tooth" We have found that at high revs, the Oem timing chain tensioner’s small ratchet can fail as it was never designed for this type of application. Dyno-mite Performance mechanical timing chain tensioners eliminate this. For a small price you could save thousands in head repair or even catastrophic failure.
