The TooHighPsi REAPER is a 12-rib supercharger belt-drive conversion for high-output C7 Corvette LT1 and LT4 applications. Compared with a 10-rib system, the wider belt provides approximately 20% more belt-to-pulley contact.

The redesigned billet tensioner bracket supports higher drive loads and provides two LT5 tensioner mounting positions for up to one inch of belt-length adjustment. The system uses a +3/-1 rib arrangement relative to the factory LT4 eight-rib layout.

Package includes: billet 6061 adjustable tensioner bracket, GM LT5 tensioner with smooth 12-rib billet idler, two ribbed 12-rib billet idlers, one smooth billet idler and mounting hardware.

Not included: crank pulley, supercharger pulley and belt.

Fitment notes: The 12-rib crank pulley requires ATI damper #917315 and a small C7 subframe modification described in the installation instructions.
