Demco Autoslide 18K 5th Wheel Replacement Head and Base Assembly
Precision-engineered automatic sliding technology for safe, smooth, and rattle-free short-bed truck towing.
Overview
The 6077-DEMCO is a heavy-duty replacement head and base assembly specifically designed for Demco Autoslide 5th-wheel hitches. Built for short-bed truck owners, this system utilizes automatic sliding technology to provide maximum cab clearance during tight maneuvers without requiring the driver to exit the vehicle. Its wraparound jaw ensures a high-security connection for a premium towing experience.
R&P Service Insight
We recommend this assembly for short-bed drivers who want to eliminate the stress of tight turns and "chucking."
- Maneuverability: Automatic 90-degree rotation prevents cab interference.
- Ride Quality: Double-pivot head design absorbs road shock on uneven terrain.
- Durability: 3/4" solid steel locking bar provides a robust, rattle-free connection.
R&P Knowledge Hub
Compatibility: Specifically engineered to fit Demco Autoslide models DM8550022, DM8550024, and DM8550034. It works with standard pin boxes 12" to 14" wide.
Vehicle / System Fit: Ideal for short-bed trucks utilizing an Autoslide system where automatic rotation is required to prevent trailer-to-cab contact.
Installation Notes: Standard pin boxes are supported natively; however, specialized pin boxes (Glide Ride, Mor Ryde, Trailair, etc.) require additional locking plates for safe operation.
Performance Insight: The double-pivot design allows the head to tilt in four directions, significantly reducing stress on the truck's frame and improving towing stability.
R&P Repair Insight
Maintenance and fitment verification are key to the longevity of your Autoslide system.
- Pin Box Check: Verify your pin box width is between 12" and 14" before ordering.
- Locking Bar: Periodically inspect the 3/4" solid steel locking bar and jaw for debris to ensure smooth engagement.
- Hardware: Always use the included safety pin and verify torque on base connection hardware during installation.
