Description

Transform your 1940-1947 Ford truck flathead into a highway-capable cruiser with this comprehensive TREMEC T5 transmission package designed specifically for Hogs Head bellhousing applications. The Hogs Head clutch housing adapter was Ford's solution for mounting heavy-duty spur gear transmissions behind the 3-inch intermediate ring — now MDL has engineered the perfect modern transmission upgrade for these unique truck setups.

The TREMEC T5 Super Duty delivers 330 ft-lb of torque capacity with a 2.95:1 first gear for strong launches and a deep 0.63:1 overdrive for relaxed highway cruising. At just 75 lbs dry weight, this is TREMEC's most compact transmission, making it ideal for the space constraints of vintage truck installations. The single overdrive drops RPMs significantly, improving drivability, reducing engine temperatures, and delivering a quieter in-cab experience on modern roads.

Modern Driveline developed a specialized Hogs Head adapter that mounts to the back of your existing clutch housing adapter and accepts the T5 transmission. This package includes a new MDL replacement fork and throwout bearing for use with a 10-inch long pattern clutch. If your OEM flywheel supports the 10-inch long pattern clutch and remains serviceable, it can be reused with a Modern Driveline clutch kit — saving cost while maintaining originality where possible.

This customizable package system allows you to build the exact drivetrain solution for your project. Choose from multiple shifter configurations, clutch options, flywheel weights, and supporting components. Every part is selected for compatibility with your Hogs Head-equipped truck, backed by MDL's decades of flathead conversion expertise and lifetime technical support.
