Extreme-Duty, Double-Bearing Design

2015-2019 C7 Z06

This 90mm billet idler pulley is designed to replace the factory idler pulley located directly to the right of the crank pulley.

This pulley offers a substantial improvement in durability and under-hood appearance.  

This pulley is approximately 3.5" in diameter and 1.75" wide at the belt surface.  It is compatible with the original 8-rib belt used in the GM LT4 application as well as custom applications using a 10-rib belt.
