TooHighPsi 12-rib overdrive crank pulleys are designed for Camaro, CTS-V and CT5-V LT1/LT4 applications using the REAPER 12-rib supercharger drive. The hard-coat anodized pulleys use a +3/-1 rib arrangement relative to the factory LT4 eight-rib drive.

Available sizes: 10.00-inch (+25%), 10.35-inch (+28%) and 10.45-inch (+30%).

Required: ATI Super Damper #918856. These pulleys do not mount to the factory crankshaft pulley. THP recommends using all six damper mounting locations.

Clearance notes: Vehicles retaining the factory sway bar require the separately available THP sway-bar fit kit. Pulleys larger than +25% require the separately available REAPER alternator-clearance bracket.

Package includes: one selected 12-rib crank pulley.
