Overview

It features an 8-rib heavy-duty tensioner with oversized idler pulleys and billet brackets for enhanced belt wrap.
Show original supplier description
It is specifically built for Corvette, CTS-V, Chevy SS, and Pontiac G8 accessory spacing, ensuring improved belt control and overall reliability. Key features of this upgraded system include a heavy-duty 8-rib belt tensioner, which provides robust performance under demanding conditions. It is complemented by oversized idler pulleys and billet brackets that significantly improve belt wrap, reducing the likelihood of belt slip. The tensioner is adjustable, allowing for flexibility with different belt sizes. To ensure proper operation, this system requires an LS3/LSA water pump and a CTS-V tensioner.
