Could This Have Saved the ’60s Muscle Car? The Dana Two-Speed Rear Axle

As you would expect, the magazines on the muscle car beat were all over the story. Hot Rod featured the Cougar Eliminator on its January, ’69 cover (below) and then tested it in June, where the axle was paired with a 428 Cobra Jet V8 and a three-speed automatic transmision. The axle provided two final drive ratios, 2.88:1 for cruising and 4.27:1 for acceleration, and the improvement at the drag strip was dramatic: 13.90 seconds through the quarter-mile beams with the tall gear versus 14.43 seconds for the cruiser. Hot Rod issued its thumbs up, and other magazines reported that the feature would be offered on Ford and Mercury models in 1970 as a $200 option.
