MORryde Rubber Pin Box
Better Handling & Smoother Towing
What is the MORryde Rubber Pin Box?
The MORryde Rubber Pin Box is a revolutionary upgrade for fifth wheel RV owners who want to eliminate the jarring ride and chucking motion that comes with traditional rigid pin boxes. By incorporating a unique rubber spring suspension system, the Rubber Pin Box absorbs road shock and vibration before it transfers to your trailer, resulting in a smoother, quieter, and more comfortable towing experience.
Key Benefits
- Smoother Towing: Rubber spring technology absorbs road shock and reduces chucking
- Reduced Wear: Less stress on your truck, hitch, and trailer frame
- Quieter Ride: Minimizes noise from road vibrations
- Easy Maintenance: Replaceable components mean long-term value
- Weight-Rated Options: Available for trailers from under 11,500 lbs to over 18,000 lbs GVWR
How It Works
The Rubber Pin Box uses a series of specially engineered rubber springs (shear springs) that compress and flex as you tow. These springs are positioned between the upper mounting assembly and lower skid pad assembly, creating a cushioning effect that absorbs bumps, potholes, and road irregularities. The result? Your fifth wheel glides smoothly behind your truck instead of jerking and bouncing.

Choosing the Right Replacement Spring
The most critical component of your Rubber Pin Box is the shear spring, and it must be matched to your trailer's Gross Vehicle Weight Rating (GVWR). Here's how to choose:
- RPB707-003S (#03 Spring): For trailers under 11,500 lbs GVWR
- RPB707-004S (#04 Spring): For trailers 11,501 - 14,000 lbs GVWR
- RPB707-005S (#05 Spring): For trailers 14,001 - 18,000 lbs GVWR
- RPB707-006S (#06 Spring): For trailers over 18,000 lbs GVWR
Important: Using the wrong spring rating can result in poor performance, excessive wear, or even damage to your pin box. Always verify your trailer's GVWR (found on the VIN sticker) before ordering.
Maintenance Tips
To keep your MORryde Rubber Pin Box performing at its best:
- Regular Inspection: Check the rubber springs for cracks, tears, or excessive wear every 6 months
- Hardware Check: Ensure all bolts and nuts are properly torqued according to MORryde specifications
- Lubrication: Keep moving parts properly lubricated
- Stability Disc: Consider the Stability Disc Replacement Kit (RPB77-009) if you experience excessive side-to-side movement
- Access Plugs: Replace damaged Access Plugs (UO196-181) to keep debris out of the assembly
