With several patented design elements that combine the best in durability, reliability, and efficiency, our Torsionally Tuned 40 Single Reduction Tandem Drive Axle is proven to deliver maximum performance with air-ride suspensions. This axle is specially "tuned" and designed to significantly reduce damaging driveline torsionals that can destroy many drivetrain components. 

• Innovative combination of hypoid and spiral bevel gearing significantly reduces excessive inter-axle driveline angles
• Eliminates need for "broken-back" axle set-up in air-ride suspensions
• Keeps driveline torsional accelerations well below acceptable limits at the full range of ride heights

Lube Pump

• Industry-proven design improves vehicle reliability
• Protects against spin-out while preventing added heat
• Keeps gears lubricated

LMS™/LMSi™

• Industry-leading hub system technology
• Reduced maintenance and improved reliability
• Increased efficiency and lower life cycle costs

Gen Tech™ Gearing

• Axle gearing manufactured for the ultimate quiet ride significantly reducing noise, vibration, and harshness (NVH)

Electromagnetic Retarder

• Designed for the most effective braking action
• Reduced complexity

Wheel Differential Lock

• For maximum traction on slippery surfaces
• Increased stability improves operator safety
• Can be retrofitted on certain models

Central Tire Inflation System

• Maximum mobility on a variety of terrains
• Enhanced efficiency extends tread life
• Reliable performance for better ride and reduced maintenance
