MORryde RPB72-1621HD-05 Pin Box System – Up to 14,001 – 18,000 GVWR
For years, fifth wheel owners have grown accustomed to the harsh, jerky back-and-forth motion that comes with towing a fifth wheel. The strain it puts on the driver, the passenger, the truck and the fifth wheel have simply been accepted as part of the towing experience. That’s where MOR/ryde’s Pin Box System enters the picture. The unique rubber shear spring works in a horizontal planar motion (both longitudinally and laterally) to absorb towing shock and effectively diminish the transfer of forces from trailer to truck. Install one and forget about that harsh, jerky chucking action – not to mention the added strain on you!
