Our custom Roots Style Blower Tensioner has a stiffer bracket and stiffer spring. It holds more tension on the belt effectively preventing slip that is more likely to occur with original tensioner. For GTO 8-rib belt drive, new 8-Rib pulley included.
This works with Magnacharger, Kenne Belle Superchargers ONLY. Does NOT work with Lysholm OR Whipple supercharger kits.
