McLeod aluminum bellhousings are the gold standard when it comes to accuracy and compact performance. They're constructed of CNC-machined spun aluminum?with a narrow body design for lightness, and a titainium inner liner for added strength and protection. These bellhousing come with a removeable inspection cover to help aide in clutch adjustment between rounds. They come in two different configuations, SFI rated with a steel block plate that gives the bellhousing its SFI 6.1 rating. We also offer a Non- SFI rated version for those customers looking for a light weight bellhousing, but not concerned with a SFI rating so these units do not come with a steel block plate.
