Quality Gear - Dana 80 Differential
The Dana/Spicer Model 80 is an automotive axle used in OEM heavy duty applications by Chevrolet, Dodge, and Ford. It can be identified by its straight axle tubes, 10 bolt asymmetrical cover, and a "80" cast in to the housing. Dana 80's are made as full floating, rear axles only and are step up in overall strength compared to the Dana 70.
Ford was the first company to use the Dana 80; it is used mostly in trucks with dual rear wheels with the exception being some Dodge 2500's and select Ford F-350's. The Dana 80 has a gross weight rating up to 11,000 lbs, however it is common practice among manufacturers to derate Dana 80's. Gross axle weight ratings are lowered by the vehicle manufacturer for safety and tire reasons.
