• No-Maintenance Design: Unlike some upgraded pin boxes that use airbags, the rubber spring in the MORryde unit requires no maintenance.
• Weight Optimization: The rubber spring is designed for trailers with a GVWR between 11,500 lbs - 14,000 lbs, ensuring proper support and shock absorption within this range.
• Reduces Chucking: Built-in glide pads allow the skid plate to move up to 3" forward/backward and 1.5" side-to-side, reducing the jerking motion (chucking) during starts, stops, and turns.
• Better Ride Quality: By absorbing movement at the hitch connection, the pin box minimizes stress and impact on both the tow vehicle and trailer for improved ride comfort.
• Direct Replacement: It is a direct replacement for the Rhino pin box, simplifying the upgrade process.
• Easy Installation: Installation is straightforward, using the existing bolt holes and hardware from the factory pin box.
• Heavy-Duty Construction: Due to its solid build, multiple people are recommended to assist with the installation for safety and ease.
• Ideal for Uneven Terrain: Especially beneficial for towing on unpaved roads or rough pavement, where vibration and road shock are more pronounced.
• Prevents Transfer of Force: The MORryde design prevents impact from transferring between the trailer and tow vehicle, protecting both from wear and potential damage.

Most standard pin boxes are constructed of steel and are built with the sole purpose of connecting your fifth-wheel trailer to your tow vehicle. There is no cushioning built in, so a factory pin box doesn't do anything to provide a comfortable ride when you're hauling your fifth-wheel trailer.

This MORryde pin box, however, is built with an internal rubber spring that absorbs road shock and vibration at the connection point. So if you're driving on unpaved roads or uneven pavement, this pin box will prevent any road shock and vibration you encounter from transferring from your tow vehicle to your fifth-wheel trailer and vice versa. In other words, the rubber spring takes the brunt of the impact so you and your towing setup don't have to. And because this unit uses a rubber spring instead of an internal air bag like some other upgraded pin boxes, there's no maintenance required.

Although this pin box can tow up to 24,000 lbs, the internal rubber shear spring is optimized for trailers that range from 11,001 to 14,000 lbs. A rubber spring built for 24,000-lb trailers would be too stiff to provide any cushion for an 14,000-lb trailer, while a rubber spring built for 14,000-lb trailers would be too flexible for a 24,000-lb trailer. To get the best results from this cushioned pin box, the sweet spot is a trailer in the 11,001-lb to 14,000-lb range.

Less Chucking for a Better Ride

Chucking, the back-and-forth jerking movement you feel in your cab when towing, occurs most frequently during starts and stops and while making turns. A typical, factory pin box creates a rigid connection without much give. So when a harsh stop occurs, all of the trailer's forward momentum gets forced through that stiff connection, slamming the king pin in the hitch and jerking your truck around.

To combat this, glide pads are built into the MORryde pin box that allow the skid plate to shift up to 3" forward and backward and 1-1/2" side to side to compensate for some of that violent motion so that you don't have to feel it in your cab.
