New standard steer axles for Peterbilt heavy-duty, over-the-road vehicles offer reduced maintenance requirements and improved tire wear, and maneuverability.

The new Dana Spicer axles are the E1202I (base model axle) and the E1202W, both rated at 12,000 pounds, and the E1322W Series, rated at 13,200 pounds.The “I” designates the standard axle width, and the “W” designates the wide-track version of the axle.

All the axles feature an enhanced Low Maintenance System that extends lube intervals to one year or 100,000 miles.

The Dana Spicer axles feature lightweight, forged integral steering arms with a power rib beam.Two in-line drawkeys with spring washers, a common large-diameter kingpin, and compressible kingpin inserts help improve axle alignment and durability, as well as improve tire wear by reducing toe change (tire bowing) under load.

Wheel cut with the new axles is up to 55°. The axles also have a 1.25" center drop in the axle beam for greater clearance with the engine oil plan.

The new axles are standard for Peterbilt Models 379, 387, 385, 378, and 362. They are also provided for Peterbilt's vocational Model 357 and medium-duty Model 330.
