Katech Inc. has been involved with the C5-R race program since 1997. There seemed to be a bad spot in the rpm range where the serpentine accessory belt would want to jump off of the pulley - this is the origin of the solid adjustable belt tensioner! After installing this tensioner on the race engine, the belt problem disappeared. Even though this problem was found on the race engines, it is also the same case with the standard LSx engines.
These belt tensioners are a must for anyone doing any sort of performance driving with a Gen 3 / 4 powered car or truck. Without it, the belt can be thrown by the stock tensioner. This is not something you want to happen when you are going down the strip or racing around the road course!
*Not recommend for use on supercharged engines unless the supercharger has a dedicated drive.

Exactly what i needed.
I had bought a cheap Ict billet tensioner but still kept throwing belts. There was no way to actually tighten it. This tensioner has provisions for a 3/8th ratchet unlike the Ict billet. Also The pulley seems to have a higher ridge then a factory one which helps out a lot. Overall Great looking billet piece that does exactly what It needs to! Will keep doing business with this company.
