Dana 35

The Dana/Spicer Model 35 is an automotive axle. It has been manufactured by Dana Holding Corporation since 1985 when American Motors (AMC) sold its axle tooling equipment to Dana.[1] The axle was named AMC-15 when it was first made in 1962.[1] Dana upgraded the axle, and added IFS and Twin Traction Beam front axle variations.

Specifications

The Dana 35 (as well as the AMC-15) is used in many vehicles. The most common applications are as a rear axle in the Jeep Cherokee, Jeep Wrangler, and Jeep Comanche and as a front axle in the Ford Explorer and Ford Ranger. It is "reliable in day-to-day street use, but notoriously the opposite when worked hard."[2]

As the AMC-15 it was used in many AMC cars, most commonly with four and six cylinder engines.
