- Full-Floating Design: High-strength axle shafts with removable hubs for easy maintenance and serviceability.
- Differential Options:
- Open differential (standard).
- Limited-slip differential (LSD) for enhanced traction.
- Locking differential (manual or automatic) for off-road/low-traction conditions.
- Electronic Traction Control (ETC) for adaptive power distribution.
- Brake System Compatibility:
- Drum Brakes: Up to 457 mm (18 inches) diameter with S-cam or wedge actuators.
- Disc Brakes: Vented rotors with multi-piston calipers for superior heat dissipation.
- ABS/ESC Integration: Standard anti-lock braking and electronic stability control compatibility.
- Material & Construction:
- Axle Housing: Forged alloy steel or nodular iron with reinforced ribbing for torsional stiffness.
- Axle Tubes: 140–160 mm diameter, 14–16 mm wall thickness for maximum load support.
- Gears: Case-carburized and ground spiral bevel gears for quiet, efficient power transmission.
- Dimensions & Weight:
- Overall Width: 1,800–2,200 mm (71–87 inches) (adjustable based on vehicle frame and track width).
- Weight: Approximately 340–380 kg (750–840 lbs) (configuration-dependent).
Technical Features
- Extreme Durability:
- Corrosion-resistant coatings (e-coat, zinc-nickel plating) for longevity in harsh environments.
- Heat-treated gears and shafts resist wear under high-load, high-cycle conditions.
- High Torque & Efficiency:
- Optimized gear tooth profiles and high-contact ratios reduce friction and energy loss.
- Low-friction seals and bearings extend service intervals.
- Modular & Scalable Design:
- Compatible with Dana’s Spicer® Pro-40™ and AdvanTEK® technologies for seamless integration with multi-axle systems.
- Plug-and-play wheel end and brake components simplify retrofits and upgrades.
- Serviceability & Maintenance:
- Easy access to differential service ports, lubrication points, and replaceable wear components.
- Extended service intervals (up to 200,000 km with synthetic gear oil).
- NVH Optimization:
- Precision-machined gears and vibration-damping mounts minimize noise and harshness.
