Description

Converting your 1948-1951 Ford Flathead truck from its original heavy-duty spur gear 4-speed to a modern 5-speed overdrive transmission requires the right adapter system. This customizable package is specifically engineered for trucks equipped with the Hogs Head clutch housing (#01T-7505) - the stand-alone bellhousing Ford used to mount their 4-speed crash box transmissions. MDL's Hogs Head adapter bolts directly to your existing clutch housing and accepts the TREMEC T5, eliminating expensive bellhousing modifications while maintaining proper clutch geometry and pedal feel.

The heart of this package is TREMEC's proven T5 5-speed with its 300 lb-ft torque rating - more than adequate for period-correct Flathead builds. At just 75 lbs dry, it's the lightest transmission in TREMEC's lineup, making it ideal for tight engine bay clearances and original floor pans. The 2.95:1 first gear provides strong takeoff performance that matches the Flathead's torque characteristics, while the deep 0.63:1 overdrive drops highway RPM significantly - reducing engine temperatures, improving fuel economy, and making long drives genuinely enjoyable.

MDL's front-shift T5 configuration moves the shifter forward to match your original transmission's position, maintaining correct ergonomics inside the cab. The package includes a custom clutch fork and throwout bearing designed for 10-inch long pattern clutches, and if your OEM flywheel supports this pattern and remains serviceable, you can reuse it with an MDL clutch kit. This guided package system walks you through every component selection - transmission, shifter, clutch set, flywheel, hardware, speedometer components, and drivetrain accessories - ensuring everything works together as a complete system.

TREMEC recommends 2.75 quarts of Dexron III ATF for the T5. Every package includes access to MDL's lifetime technical support to help you through installation and setup. Made in the USA.
