Product Overview
When you're mating an LS engine to a TREMEC TKO or TKX transmission, this aluminum bellhousing delivers the direct connection you need without adapter plates or unnecessary complexity. Manufactured by McLeod Racing, it's engineered as a non-SFI rated option for builders who want lightweight performance on street-driven builds where a steel scatter shield isn't mandated -- perfect for cruisers and mild street machines under 500 horsepower.
The bellhousing uses the time-tested GM Muncie 4-speed bolt pattern that's been the standard for decades, ensuring seamless compatibility with TREMEC's TKO and TKX 5-speed transmissions. This means your LS swap bolts up clean, maintaining proper clutch geometry and bellhousing alignment that's critical for smooth engagement and component longevity. The aluminum construction shaves weight compared to steel alternatives while delivering the precision fit McLeod Racing is known for.
This bellhousing accommodates both mechanical fork and hydraulic clutch release systems, giving you flexibility in how you configure your clutch linkage. Note that the fork pivot is sold separately -- see item MD-401-6026 for the correct pivot stud. The included cover plates and serrated flange hardware ensure a secure, rattle-free installation. For builds exceeding 500 horsepower or any racing application, consider stepping up to an SFI-rated steel bellhousing for added safety. Made in the USA.
