I have been running the KP Saltwater Auto Tensioner for almost 2 years now without any issues. Having this part has reduced my maintenance down-time exponentially as I no longer need to grease my pivot bushing or spring bushings! I ride about 150 hrs a year in mostly salt water conditions and am thankful that KP produces parts and components to support ocean riders!
