Description
Upgrade Your LS Drive to this Heavy-Duty 8-Rib Belt Drive System and eliminate belt slip and maximize the performance of your supercharged setup with this premium 8-Rib Belt Drive Upgrade. Designed for enthusiasts who have pushed the limits of the factory 6-rib system, this kit provides the structural rigidity and increased surface contact required to maintain consistent boost under high load.

Why Upgrade from OEM?
The factory accessory drive is often the "weak link" when adding power. As you increase boost or move to a larger crank pulley, the standard belt often stretches or slides, leading to a loss of power and premature belt wear.
This kit solves those issues through:
Superior Belt Wrap: This upgrade is a precision-machined Billet Aluminum Brackets that are engineered to wrap the belt further around the pulleys, significantly increasing the contact patch and preventing "chatter" or slipping.
Heavy-Duty Tensioning: Unlike the standard plastic or light-duty OEM units, our upgraded 8-rib tensioner and 110mm oversized idler maintain rock-solid alignment and constant pressure.
Custom Adjustability: The tensioner bracket features a clocking design, allowing you to fine-tune the tensioner's position to accommodate various belt lengths and pulley combinations perfectly.
Compatibility & Requirements
This system is designed for Chevy SS Sedan, Pontiac G8 and CTS-V accessory spacing. To ensure a perfect fit, please note the following:
Water Pump: Requires an LS3/LSA style pump (Part #19180610) with tapped bosses for the idler bracket.
Tensioner: Must be paired with a CTS-V Drive Belt Tensioner (ACDelco #12628025).
Recommended Belt: When running a stock upper and 9.25" lower pulley, use part number K080683HD.
