Dana 80

The Dana/Spicer Model 80 is an automotive axle manufactured by Dana Holding Corporation and has been 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 into the housing.

Gross axle weight ratings are lowered by the vehicle manufacturer for safety and tire reasons.

Trac Loks were a US$350.00 option with Ford Super Duty trucks.

Ford has made use of the axle in class 4 trucks until 2005 when the Dana S 110 was phased in.
