The BBM to TH400 Ultra-Bell is a premium aluminum bellhousing specifically designed for Mopar B and RB-series engines paired with TH400 transmissions. This SFI 30.1-certified bellhousing is ideal for high-performance applications, bridging the gap between big-block Chrysler engine families and one of the most durable automatic transmissions available.
Constructed from lightweight aluminum, the Ultra-Bell combines structural integrity with reduced rotating mass, which is crucial for improving acceleration and handling balance in drag racing and street performance. The SFI 30.1 certification ensures that this bellhousing meets safety standards for high-performance engine combinations, providing proper containment during catastrophic failures.
This bellhousing is particularly beneficial for builders and restorers performing modern TH400 conversions on classic Mopar B and RB-powered vehicles, as well as those constructing high-output engines for competition. The Ultra-Bell's natural aluminum finish not only provides a clean appearance but also allows for custom finishing if desired, making it a versatile choice for enthusiasts.
