Koso Cam Timing Chain Tensioner Upgrade
DHM uses this piece on all of our modified engines! It prevents the failure of the stock rubber wheel that falls apart after extended high RPM use.
"Made from resistant high quality material, our Koso chain tensioner could save your engine from expensive damage. We came up with this long lasting solution to replace the OEM chain tensioner which has a tendency to wear prematurely."
Flywheel removal is required to install this product.
Great when paired with the Decha Performance manual chain tensioner, found HERE
