For Coyote swap customers utilizing the PBH Coyote Swap accessory bracket kit with 11-up GT/Boss alternator you must run a clutchless pulley. All manual transmission cars and FRPP Boss alternator kits come with a clutch style pulley. Trying to use this setup with PBH brackets will result in an alternator that spins but does not charge.
These pulleys are machined out of aluminum and also are much lighter than stock. All pulleys are anodized black.
