They have gone through SFI’s explosion-proof testing procedures and have come out the other side with a SFI 30.1 rating! Manufactured from one-piece A356-T6 cast aluminium, they are roughly 5 times stronger than standard replacement bellhousings and can withstand the harshest tyre shake, while still being able to fit under most floorpans.
