Innovative and state-of-the-art engineering gives these axles market-leading performance and value. Consider the features and benefits listed below.

Features & Benefits

• The above-center-pinion position of the rear-rear axle results in improved driveline angle and a significant reduction of driveline vibrations
• A larger power divider results in improved stability and reliability
• Precision ground gear sets provide for a quieter and smoother operation, while allowing higher torque applications
• Elimination of pinion head bearing allows the use of a larger differential, for added stability and durability
• Robust design and ease of maintenance reduce life cycle costs
• Accepts all brakes offered in the Western Star Data Book
• Warranty is based on truck application up to 5 years, 750,000 miles*
