Drive Strength
The larger differential is just the first reason why our proprietary single proprietary rear axles are
more durable. Add increased ground clearance, precision cut gear sets and a
solid warranty, and it is obvious why these axles are a clear advantage.
- Up to 23,000 Lbs Capacity
- Up to 1100 lb-ft Torque
- From 2.92 to 6.85 Available Ratios
- Up to 128 Lbs Weight Advantage
Performance
Lightweight—Single rear axles are significantly lighter than other brands: up
to 128 lbs less,* which results in added fuel efficiency and maximum payload.
* (depending on model)
Precision Ground Gears - The ring gear and pinion tooth profiles are precision ground, using a state-of-the-art manufacturing process to ensure a consistent gear mesh, resulting in quieter and more efficient operation with longer gear life.
Innovation
Larger Differential – The elimination of the pinion head bearing provides
additional space and allows the use of a larger differential.
Brake Compatibility—Proprietary single rear axles are compatible with
all brakes offered by Freightliner, Sterling, and Western Star Trucks.
Reliability
Lower Life Cycle Cost—Easy maintenance and less oil capacity reduce the life
cycle cost of the axle, while the pinion and carrier flange deliver top-notch
oil seal performance.
Warranty
2 years / unlimited miles. Call you dealership for more detailed information.
