Description

Add more strength, capacity, cooling, and style to your rear axle. Constructed from thick A356.0-T6 aluminum for faster heat dissipation, keeping fluid temperatures lower. Features a reinforced center bar for extra strength and load bolts to prevent bearing cap deflection. The internal shape promotes proper fluid flow over the ring gear for lubrication. Includes a magnetic drain plug, MIL-Spec (MIL-A-8625) black anodized finish, machined B&M logo, and all necessary hardware. Gasket not included.
