Starlite Diesel Duramax Belt Tensioner Assembly 01-16

The StarLite Diesel tensioner replaces the factory belt tension that *ALL* known dual cp3 kits still use, with not 1 piece but 2 separate pieces, that effectively take all the slack and slop out of the belt and let you tighten to the belt to your specs. When properly installed, this system eliminates the need and worry about anything besides maintenance on the belt tension as it stretches over time and takes makes losing a belt on your way down the track the least of your worries from now on!
