Our AWD B-Series Billet Bellhousing is the go-to product for top teams and shops. Expertly machined from solid 6061-T6 aluminum billet, it offers superior quality and exceptional performance. It also has a 9lb heavier weight than OEM to ensure extreme strength and durability for street and racing use. With updated features, our bellhousing provides precision fitment with no grinding needed, and is designed to clear oversized PPG crown wheel and transfer drive gear, as well as retain OEM oil control options. It also comes with a built-in axle seal stop for simple installation. Compatible with all known aftermarket gearsets, transfer drive gears, and differentials, our bellhousing requires assembly and shimming to OEM specs. It is prepped for use after 2022 but may need minor clearancing for stock clutch forks before 2021. Professional installation by a transmission specialist is recommended for optimal performance.
