TooHighPsi 12-rib overdrive crank pulleys are designed for dry-sump C7 Corvette LT1 and 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: 9.88-inch (+23%) and 10.45-inch (+30%).

Required: ATI Super Damper #917315. These pulleys do not mount to the factory crankshaft pulley.

Chassis note: Installation requires a small modification to the C7 chassis crossmember as described in the THP instructions.

Package includes: one selected 12-rib crank pulley and mounting hardware.
