Dana Corp's Commercial Vehicle Systems unit is offering the new Dana Spicer S110 drive axle, designed to meet the varying needs of the Class 4/5 truck market. The S110 series axle is built for all drivetrain configurations that require axle weight ratings from 10,000 to 14,500 pounds, GVW ratings up to 23,500 pounds, and GCW up to 35,000 pounds.

The High Power Density (HPD) design methods maximize component life and improve impact resistance at greater loads while minimizing weight and cost. The 300-M hypoid gearing and wheel differential optimize strength and lengthen axle life when used with high-horsepower engines. The bolted oval axle carrier assembly, welded housing cover, and flat-bottom axle housing increase ground clearance. Fabricated from high-strength, hot-formed, micro-alloy steel with a square-edge box section, the axle housing is designed for various vehicle suspension configurations. The high-capacity precision pinion bearing system lessens deflection under heavy load. A new one-piece steel-forged ring gear/differential case boosts stiffness.

The 345-lb axle assembly increases payload. Reduced pinion standout distance enhances vehicle installation flexibility and improves driveline angles. Axle ratios range from 3.07 to 6.50. An optional full-locking driver-controlled differential lock can be specified, as well as a limited-slip differential that provides an automated mechanical traction system.
