Why Choose the MORryde RPB707-005S Pin Box Replacement Spring?
Not all pin box springs are created equal. Using the wrong spring number — or an off-brand substitute — can compromise your trailer's handling, accelerate wear on your pin box, and create dangerous towing conditions. The MORryde RPB707-005S is engineered specifically for the 14,001 – 18,000 lb GVWR range, ensuring your pin box operates within its designed parameters.
MORryde's rubber spring technology provides progressive resistance — absorbing small bumps smoothly while handling larger impacts without bottoming out. The result is a noticeably quieter, more stable tow that protects both your trailer and your tow vehicle.
When you need a pin box replacement spring you can trust, the genuine MORryde RPB707-005S is the only choice that guarantees factory-correct performance.
