MOR/Ryde RPB77-FD-06 No Supplier Warranty
The MORryde pin box system utilizes a unique rubber shear spring to positively deal with rough towing and road shock. The rubber spring works in a horizontal planar motion (in a longitudinal and lateral motion) to absorb the towing shock. This allows the MORryde pin box system to effectively diminish the transfer of forces from the trailer to the truck. Fifth wheel owners know about that harsh, jerky, chucking action that comes from towing a fifth wheel. They also recognize that some roads will just wear you out from that jerking/chucking action. They have just come to accept it as a normal part of towing. These uncomfortable aspects of towing are the result of longitudinal and lateral forces being transmitted from the trailer to the truck. They cause that troublesome chucking action you feel, especially on Interstate highways with expansion joints. They also contribute to the harshness and jerking you feel when going over railroad tracks or roads with that washboard effect. And, these forces cause that "clunking feeling" when you come to a stop and start up again.
