Mopar Street Rod & Dodge Truck TREMEC TKX, Magnum, & A41 Overdrive Kits

Bring modern Mopar muscle to your custom build with our Dodge Street Rod and Classic Truck Transmission Kits. Whether you are powering a 1930s Dodge Coupe, a custom street rod with a 392 Hemi, or a D100/D200 Sweptline with a modern 5.7L Hemi, we offer the industry’s most refined overdrive solutions. Choose from the compact TKX 5-Speed, the massive torque capacity of the Magnum 6-Speed, or our precision-shifting A41 4L60E Electronic Automatic.
 

Engineered to solve the unique packaging challenges of Mopar-powered projects, our kits provide a seamless fit into classic cabs and tight custom chassis. By significantly reducing highway RPMs, our systems transform your Dodge truck or street rod into a reliable, long-distance cruiser. Each kit arrives as a total solution, featuring all the high-quality components necessary to pair modern overdrive with your Small Block, Big Block, or Gen III Hemi, while maintaining the correct shifter location for your bench seat or custom interior.
