Innovators West 8-Rib Conversion Kit for Trailblazer SS

Innovators West drive pulley conversion kits upgrade your vehicle to an 8-rib drive with standard balancer—or you can switch to a 10 percent overdrive balancer. Each Innovators West conversion kit delivers not only the pulleys, but also an SFI 18.1 stickered and stamped harmonic balancer.

Kit includes:

• 8-Rib Drive – Standard Diameter Damper
• 8-Rib GM Alternator Pulley or Underdrive 8-Rib Alternator Pulley
• 8-Rib P/S Pulley
• 8-Rib LS Truck Large Smooth Idler Pulley
• 8-Rib Ribbed Tensioner Pulley

Options:
The Super Duty Hub option is a thicker hub that provides greater resistance to hub cracking under high power supercharged applications (750 RWHP and greater). This option includes a new custom made timing cover seal to adapt the oversized hub to a stock timing cover.

The Underdrive alternator pulley option is a larger diameter pulley designed to slow the alternator down when using an Overdrive diameter damper along with an engine with extended RPM range. This can help combat the overspeed failures in OEM alternators.
