DS344 | DS404-(P) | DS405-(P)

Leaner. Meaner. Lighter. Lower. Tougher.

Here’s how the 404 translates to increased productivity for your operation.

• "Fast-fade" housing design for lower fifth wheel heights to increase payload capacity and improve vehicle stability.
• Standard Flow-Thru lube system, a Dana Spicer exclusive, supplies maximum lubrication to critical areas throughout the power divider unit.
• Broader range of hypoid primary gear ratios allow for optimum powertrain specification.
• Larger inter-axle differential assembly and lockout clutch designed to meet the demands of most applications.
• Stronger wheel differential assembly for increased performance and resistance to shock loading.
• Premium Microlip™XL seals provide the most effective sealing system available to keep lube in, dirt and grime out.
• Factory fill with approved synthetic lubricants that require no initial drain to save you time and money. Drain intervals extended to 500,000 miles with approved synthetic lubes and no maintenance "U" tube breather.
• Optional features provide the flexibility to spec your vehicle to match your operating needs:
  • Driver controlled wheel differential lock for improved traction over slippery or uneven surfaces.
  • Premium “gerotor’’ style lube pump system for added protection in severe service operations.
  • In-axle speed sensors (IASS) improved system reliability, eliminate sensor adjustment, and reduce maintenance cost over the life of the vehicle.
