Improved Driveline Angle
Tough, stable and reliable: Detroit™ tandem rear axles are among the most robust and powerful in the industry. Precision-machined gears, larger differential and a reduced driveline angle increase the longevity of the axle and drive down costs. Using our Topoid design, Detroit tandem rear axle systems have an above-center position of the pinion gear to reduce the driveline angle between the forward and rear axles. That means fewer driveline vibrations, less wear and a much longer life.
Spec'd for Fuel Economy
Our Tandem Rear Axles are available with a 2.53 ratio for all on-highway applications. Together with the Detroit DD15 engine, and a direct drive transmission, this is one great way to increase your overall fuel economy.
Ask your dealer how Detroit drivetrain configurations can help you improve your fuel economy and overall performance.
Precision Machined Gears
The ring and pinion gears ensure consistent gear mesh and optimal power flow. The tighter tolerances mean a quieter, smoother ride and allow higher torque input than other rear axle brands.
To ensure full lubrication of the power divider — even at very low speeds — we added our patented oil deflector as a standard feature on all tandem axles. This removes the need for an axle oil pump for most applications and lowers your cost of operation and maintenance.
Advanced Seal Design
Current market designs have the seal located inside of the input threaded ring, leaving a gap between the threads, causing it to degrade and prematurely leak. Our advanced design separates the seal from the threaded ring for superior sealing and leak protection.
Single Tire Applications
40,000-lb tandem axles are available with optional intermediate track housing, which allows the use of single or dual tires. With a 34,000 lbs rated capacity, Detroit allows dual or single tires with the standard housing configuration.
