MORryde Rubber Pin Box RPB72-1621SHD-TA-06 - Revolutionary Fifth Wheel Towing System
Experience the smoothest fifth wheel towing you've ever had with the MORryde Rubber Pin Box RPB72-1621SHD-TA-06. This revolutionary pin box system is specifically designed to replace the Lippert 1621SHD pin box (plus 2 inches) on the heaviest fifth wheels with a GVWR over 18,000 lbs, delivering a jerk-free, chuck-free ride that transforms your towing experience even with the largest residential and luxury fifth wheels.
If you're tired of the uncomfortable jerking and chucking that comes with traditional rigid pin boxes, especially on heavy-duty fifth wheels, the MORryde Rubber Pin Box changes everything. Its patented rubber shear spring technology absorbs road shock and eliminates the troublesome aspects of towing, making every trip smoother and more enjoyable regardless of your trailer's weight.
Why Choose the MORryde Rubber Pin Box RPB72-1621SHD-TA-06?
The MORryde Pin Box creates a smoother ride and eliminates the troublesome aspects of towing fifth wheels by greatly reducing chucking and jerking on all types of road conditions. The rubber shear springs act as cushions, effectively reducing road shock while maintaining full horizontal planar motion. This means you'll experience significantly less wear and tear on both your fifth wheel and tow vehicle, while enjoying a more comfortable ride that makes towing actually enjoyable.
Unlike air-lifted springs that can leak or shock absorbers that need replacement, the MORryde rubber pin box has a long component life with continuous performance. Installation is simple and takes about an hour on most fifth wheels, with no maintenance required after installation. For the heaviest fifth wheels over 18,000 lbs GVWR, this is the ultimate upgrade that delivers premium ride quality.

How It Works
The MORryde Rubber Pin Box uses patented rubber shear spring technology that fundamentally changes how forces transfer between your fifth wheel and tow vehicle. When you hit bumps, potholes, or uneven road surfaces, the rubber shear springs compress and absorb the shock instead of transmitting it directly to your truck. This cushioning effect eliminates the jarring chucking sensation while still allowing the pin box to maintain proper horizontal movement for safe turning and maneuvering. For the heaviest fifth wheels over 18,000 lbs, this technology makes a dramatic difference in ride quality and reduces stress on both your trailer and truck.

Frequently Asked Questions
How does the MORryde Rubber Pin Box reduce chucking?
The patented rubber shear spring technology absorbs up to 3 inches of fore/aft movement and 1.5 inches of lateral movement, cushioning the transfer of forces between your fifth wheel and truck. This eliminates the jarring back-and-forth motion that causes chucking, especially important on the heaviest fifth wheels.
Will this fit my fifth wheel with a Lippert 1621SHD pin box over 18,000 lbs?
Yes, the RPB72-1621SHD-TA-06 is specifically designed as a direct replacement for Lippert 1621SHD pin boxes (plus 2 inches) on fifth wheels with a GVWR over 18,000 lbs. It's engineered to bolt right in place of your existing pin box.
What does the +2 inches mean?
The +2 inches refers to the additional length this pin box provides compared to the standard Lippert 1621SHD. This extra length can help with truck clearance and turning radius on certain fifth wheel and truck combinations, especially important on heavy trailers.
What's the difference between the TA-06 and TA-05?
The RPB72-1621SHD-TA-06 is designed for the heaviest fifth wheels over 18,000 lbs GVWR, while the TA-05 is for trailers between 14,001-18,000 lbs. Both replace Lippert 1621SHD pin boxes with the +2 inch design, but the TA-06 is engineered for maximum weight capacity.
How long does installation take?
Installation typically takes about one hour on most fifth wheels. The process is straightforward and can be completed by most RV owners with basic tools, though professional installation is recommended for heavy-duty applications.
Does the rubber pin box require maintenance?
No, that's one of the major advantages of the MORryde system. Unlike air-lifted springs that can leak or shock absorbers that wear out, the rubber pin box requires no maintenance and delivers continuous performance throughout its long service life.
What's the difference between this and an air ride pin box?
The MORryde Rubber Pin Box uses solid rubber shear springs that never need adjustment or maintenance, while air ride systems use air bags that require monitoring and can develop leaks. The rubber system provides consistent, reliable performance without the complexity of air suspension.
Will this work with my truck's fifth wheel hitch?
Yes, the MORryde Rubber Pin Box works with all standard fifth wheel hitches. It replaces the pin box on your trailer side, not your truck's hitch, so it's compatible with any fifth wheel hitch system.
Is this suitable for toy haulers?
Absolutely! The RPB72-1621SHD-TA-06 is perfect for heavy-duty toy haulers over 18,000 lbs GVWR. The rubber shear spring technology handles the weight and provides a smoother ride even with heavy cargo loaded in the rear.
Is professional installation recommended?
While many RV owners can install this themselves, professional installation is recommended for the heaviest fifth wheels to ensure proper torque specifications and alignment. This ensures optimal performance and safety.
