Dana 50
The Dana/Spicer Model 50 was an automotive axle manufactured by the Dana Holding Corporation for 25 years and was used solely in OEM Ford applications. Dana 50's were made as front axles only until it was revived in rear solid axle configuration in the 2022 Ford Bronco Raptor. The Dana 50 has a "50" cast into the housing and is regarded to have more strength than a Dana 44, but not as much as a Dana 60. It was only produced in a reverse cut gear set aka a high pinion. The Dana 50 was made as a solid axle and as a Twin Traction Beam (TTB) which pivots in the center allowing the wheels to move independently of each other.
