Street Race Truck More... The Toolbox

The famous two-speed automatic transmission designed by General Motors, known as the Powerglide, is an all-time favorite among rodders and racers of all types. Known for its simplicity and durability, the GM Powerglide can be found at the drag strip or in monster trucks and at mud racing events. Two types of Powerglides came in a cast or aluminum form, coupled behind inline 6 and 4 cylinder, and small block V8 engines. Here at Speedway Motors, we know Powerglides and we can help you get the most out of your two-speed automatic with a wide selection of replacement and aftermarket upgrade components. Whether you’re building a classic street rod or restoring that old Chevy, turn to Speedway Motors, your one stop shop for everything Powerglide!
