10 Rib Belt Drive & Crank Pulley - Camaro / CTS-V / CT5-V - LT1 / LT4

TooHighPsi's 10-rib crank pulley, billet idlers and upgraded tensioner bracket provide improved belt control for supercharged Camaro, CTS-V and CT5-V LT1/LT4 applications.

The upgraded drive system provides 30% more peak belt tension, 12% more belt-length take-up and a 48% larger tensioner shaft and bearing assembly.

Select: +15%, +23% or +28% 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.

Fitment notes: The +23% and +28% pulleys require the separately available TooHighPsi sway-bar fit kit to retain the factory front sway bar. ATI damper #918856 is required; the lower pulley does not mount directly to the factory crank pulley.
