"A Little Locker History
The Detroit Locker was initially called a “Thornton NoSPIN Differential.” Ray Thornton patented it in 1941 as device for use in six wheel (tandem drive) truck applications. The NoSPIN was manufactured by the Detroit Automotive Product Corporation and was used on American military vehicles during World War II.
After the war and into the 1960s, the Thornton NoSPIN was original equipment on light and medium duty trucks. That’s right about when it got the Detroit Locker nickname—and when racers and high performance enthusiasts started to take an interest in it. They used the Detroit Locker on everything from road racers to NASCAR roundy-rounders and land speed record cars. In the late 1960s, some Ford performance cars had the Detroit Locker as a factory option. And to no one’s surprise, the Detroit Locker was found in cars at virtually every drag strip in the nation."https://www.onallcylinders.com/.../detroit-locker.../
