Enhance Performance - Replacing the twin cam chain tensioner with a new one can keep the chain at proper tension during operation, avoiding over-loosening or over-tightening of the chain, ensuring good meshing between the chain and sprocket, and enhancing engine performance
Reinforced Connection - Our upgraded Dyna chain tensioner features reinforced connection points, so you don't have to worry about parts falling apart during installation
Stainless Steel - Our Street Glide tensioners are made of high-quality stainless steel and thickened rubber pad to ensure that they can withstand the high temperature and high pressure environment when the engine is running, and have good wear resistance and durability
Reduce Noise - Our Road glide chian tensioner can reduce the vibration and noise generated when the chain is running, making the engine run smoother and quieter, and improving the driving experience
Installation - Professional tools are required for installation. Once it is in place, it is recommended to use tools to reinforce it to avoid the spring from slipping. Please check the video for detailed installation steps
Tips - We recommend replacing the chain tensioner with a new one when there is an unusual noise, lack of power, increased fuel consumption, and 20,000 - 30,000 miles traveled
