TooHighPsi's 10-rib crank pulley, billet idlers and upgraded tensioner bracket provide improved belt control for supercharged C7 Corvette LT1 and LT4 applications.

The upgraded drive system provides 30% more peak belt tension, 15% more belt-length take-up and a 48% larger tensioner shaft and bearing assembly.

Select: +15% or +22% crankshaft pulley.

Package includes: TooHighPsi 10-rib lower pulley, billet tensioner bracket, GM LT5 belt tensioner with smooth idler, two ribbed 70 mm billet idlers, one smooth billet idler, pulley spacers and mounting hardware.

TooHighPsi 10-rib systems use a +2 arrangement, placing the additional two ribs forward of the factory eight-rib position.

Required: ATI damper #917315. The lower pulley does not mount directly to the factory crank pulley.
