Hawks Motorsports offers our clients this 988-KIT LS1 GTO 8-Rib Drive Conversion Kit, Innovators West. This kit is designed to convert compatible LS1-powered Pontiac GTO accessory drives from the factory 6-rib setup to an 8-rib serpentine belt drive. It brings the crank, power steering, alternator, tensioner, and idler pulleys together around a common 8-rib belt system.

Once you start leaning on an LS1 with boost, RPM, or both, the belt drive deserves some attention. An 8-rib setup gives the belt more contact with the pulleys and is a much better match for a serious supercharged combination than trying to make the stock 6-rib arrangement handle everything. The 988-KIT gives you the pieces to build the front of the GTO around a dedicated 8-rib drive while retaining the standard-diameter damper configuration.

INSTALLATION NOTES:

• This listing is for one 988-KIT 8-rib drive conversion kit.
• Verify all kit components before installation.
• Serpentine belt is not included unless specifically stated.
• Verify crank, alternator, power steering, tensioner, and idler pulley alignment before final installation.
• Confirm belt length and routing after completing the conversion.
• Inspect the crankshaft snout, keyway, and damper mounting surface before installation.
• Use the proper harmonic damper installation procedure.
• Follow manufacturer torque specifications.
• Verify fitment before ordering on modified or swapped GTOs.

Super Duty Blower Hub Option:

• The Super Duty Blower Hub is a thicker hub designed to provide greater resistance to hub cracking under high-power supercharged applications producing 750 rwhp and greater.
• This option includes a new custom-made timing cover seal to adapt the oversized hub to a stock timing cover.

Underdrive Alternator Option:

• The Underdrive Alternator option uses a larger-diameter 2.800-inch alternator pulley designed to slow alternator speed on high-RPM race engines operating at 7,500 RPM or higher.
• Slowing the alternator can cause charging issues at idle, particularly on street-driven vehicles.
• This option is intended primarily for high-RPM race applications.
