Platinum Racing Products offers oil pump driven pulleys utilizing a taper grip locking mechanism.  These hub adaptors allow the fitment of the Dailey range of pulleys to most harmonic balancers. Their taper lock pulleys eliminate the need for set screws, so the oil pump drive shafts remain undamaged when adjusted or removed.  Please Note: These hubs suit the Platinum Racing Products "Dry Sump Kits" ONLY!
