Oil Deflector

Oil deflector for full lubrication at very low speeds.

Seal Design

New seal design for optimal leak protection.

Brake Compatibility

Compatible with all brake systems offered by Freightliner Trucks and Western Star Trucks.

Topoid Design

Reduced driveline angle for less driveline vibrations results in less noise and less wear.

Larger Differential

Larger differential adds stiffness, stability and durability.

Power Divider

Larger Power Divider with helical gears and needle bearings for increased durability.

 

Hypoid and Topoid Gearing

The inter-axle driveline on Detroit tandem-rear axles features a Topoid off-set, in which the centerline of the pinion is above the centerline of the ring gear on the second rear axle. This creates a near 0° driveline angle between each axle, reducing vibration, increasing durability and enhancing driver comfort.

Full lubrication at low speeds with oil deflector.

Thorough Lubrication

The inter-axle differential gears are completely lubricated—even at low speeds—using an oil deflector connected to the upper helical gear that redirects the oil toward the roller bearings into the carrier that feeds the input bearing. Standard on all Detroit tandem axles, the oil deflector eliminates the need for an oil pump in most applications to extend gear life, reducing lifecycle costs and improving durability.

Intermediate Track Housing

Our innovative designs help maximize fuel economy. That’s why our 40,000-lbs tandem axles are available with optional 11mm intermediate-track housing which allows the use of super-single or dual tires. Up to 34,000-lbs rated capacity, Detroit allows dual or single tires with the standard housing configuration. Super-single tires deliver the lightest axle/wheel combination compared to dual tires.

Tandem Steer Axle Specifications

Advanced Input Seal

Unlike our competitors, Detroit axles feature an innovative design for the input seal, which is inside the bearing cage and separated from the threaded ring to improve sealing. This significantly reduces seal degradation and input oil leaks common to other designs and eliminates the need for sealant on the threaded ring, providing better reliability and less downtime.

Higher Fuel Efficiency

Our tandem axles are available with a 2.53 ratio for all on-highway applications. Combine our tandem axle with our DD15^® engine and a direct drive transmission to get the most fuel-efficient powertain in its class and application.

Warranty

We back your investment with our standard, comprehensive warranty to cover your tandem truck axle over the long haul—up to 5 years / 750,000 miles.

Optional Equipment

• Driver Controlled Differential Lock (DCDL)
• NoSpin - for automatic differential locking
