Rubber Shear Spring Absorbs and Dampens Road Shock

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 11,501 lbs or less. A rubber spring built for 18,000-lb trailers would be too stiff to provide any cushion for an 11,500-lb trailer, while a rubber spring built for 11,500-lb trailers would be too flexible for a 18,000-lb trailer. To get the best results from this cushioned pin box, the sweet spot is a trailer in the 11,501-lb or less 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.

Bolt-On Installation

This MORryde pin box is a direct replacement for your existing Lippert Rhino pin box, so the installation is very straightforward. After removing your old Lippert pin box, the MORryde can be mounted into place using the same hardware and bolt holes used by the factory pin box.

Because of the weight of the unit, you'll want a couple of friends to help you lift it into place during installation. Once the hardware is securely bolted down, you'll be ready to go.
