Robust TH400 Conversion for LS Engines

The TH400 is legendary for its durability, and when paired with a modern GM LS engine, it creates a formidable drivetrain combination. The JW Performance Transmissions Ultra-Bell for the TH400 is designed to bridge the gap between these two platforms with unmatched strength. This SFI 30.1 certified bellhousing is a mandatory upgrade for any serious racer looking to ensure their transmission setup meets modern safety standards.

Technical Advantages

• SFI 30.1 Certification: Meets the highest safety requirements for competitive drag racing.
• Heavy-Duty Aluminum: Engineered to handle the high torque of LS-series engines.
• Direct Fitment: Designed specifically for LS-to-TH400 applications for a perfect alignment.
• Enhanced Durability: Prevents case deflection and improves overall transmission longevity.

Upgrading to an Ultra-Bell is the best way to protect your investment. The TH400 is known for its ability to handle immense power, but the bellhousing area is often a weak point when adapting to different engine platforms. This JW Performance unit eliminates that vulnerability, providing a solid foundation for your transmission. Whether you are building a street-legal powerhouse or a dedicated track monster, this component ensures your drivetrain stays intact under extreme load.
