Actually two axles in one! Single reduction gearing for highway speeds, and planetary double reduction gearing for high torque, deep-hole pulling power off-highway. Dual range feature eliminates the need for auxiliary transmissions, extreme overdrives and deep reduction transmissions.
Reasons to spec a Dana Spicer Dual Range over a single reduction axle:
- Greater operational flexibility with low and high ratios. Smooth truck operation…on or off-highway.
- Easy to operate. A hand-operated toggle valve sets an air shift system into action to change ranges.
- Increases truck resale value.
- High resistance to spin-out and shock loading.
- Involute splines on drive pinions and shafts for greater torque capacity.
- Precision Flow forged differential gears for greater strength and impact resistance.
- Standard power divider lube pump on models rated at 45,000 lbs. and greater provides optimum power divider lubrication for long life and dependable performance.
- Patented lube flow system for superior spin-out protection.
- Premium performance Viton™ Microlip™ oil seals standard on models rated at 40,000 lbs. to 45,000 lbs.
- High performance Viton triple lip oil seals virtually eliminate oil leakage problems on models rated at 46,000 lbs. and above.
- Full range of available ratios cover a wide variety of applications.
- High-entry or standard tandems available in "extra" heavy-duty axles.
