Although the Supercharged LS9 engine on the C6ZR1 has an 11 rib belt driving the supercharger, in many cases it is not enough to prevent belt slip. Smaller than stock pulleys, combined with inadequate belt wrap from the factory is a recipe for belt slip on the ZR1 that we have seen and been dealing with for many years. The best solution up to this point was fighting to install the tightest belt possible while frequently changing belts to keep belt slip to a minimum.

Aside from belt slip, the OEM tensioners have been known to fail for a variety of reasons.

We took all of these issues into consideration and decided a new tensioner was necessary with a complete design overhaul. Performance, durability, and appearance were all taken into account during the design process to come up with the best possible alternative solution for a belt tensioner. See comparison which shows an additional 55 degrees of belt wrap in the middle of the belt travel. This massive increase in wrap will slow down belt wear, and allow for use of pulleys all the way down to 2.175"
