1. MorRyde Rubber Pin Box: Best for Smooth Ride
The MorRyde Rubber Pin Box uses a rubber shear spring to isolate the trailer from the tow vehicle, dramatically reducing chucking and road shock. In our evaluation based on owner feedback and spec sheets, this is one of the most effective passive pin boxes for ride quality. It bolts directly to the trailer frame in minutes, and the rubber element is field-replaceable. However, it adds some weight and does not offer adjustable damping.
This pin box is ideal for those who want a proven, low-maintenance upgrade without air lines or electronics. Skip it if you need a lightweight solution or want active load leveling; consider an air-ride model instead.
- Rubber shear spring design absorbs road shock and reduces chucking significantly.
- Bolt-on installation using existing holes; no welding required.
- Durable construction with corrosion-resistant coating.
Pros: Noticeably smoother ride compared to standard pin boxes.; Easy to install with basic tools.
Cons: Heavier than some air-ride options.
2. Trailer Air Ride Pin Box: Best Air Ride
The Trailer Air Ride Pin Box uses an air bag to cushion the connection, offering superior vibration damping and load leveling. Based on owner feedback, it provides a noticeably smoother ride, especially on rough roads. However, installation is more involved than rubber models, and you must monitor air pressure. Some users reported air leaks over time.
This is a great choice for full-timers or those towing heavy loads who want maximum comfort. Skip it if you prefer a set-and-forget solution or are not comfortable with air systems.
- Air bag suspension absorbs vibrations and allows load leveling.
- Adjustable air pressure for fine-tuning ride quality.
- Includes inflation valve and mounting hardware.
Pros: Excellent ride quality with adjustable firmness.; Reduces wear on trailer and truck.
Cons: Requires periodic air pressure checks and potential leaks.
3. Reese Sidewinder Pin Box: Best for Tight Maneuvering
The Reese Sidewinder pin box is designed for those who need extra clearance when backing into tight spots. Its rotating mechanism shifts the pivot point, allowing sharper turns without the trailer contacting the cab. In our research, owners appreciate the improved maneuverability, but note that it does nothing to smooth the ride and can creak during rotation.
This is the pick for RVers who frequently navigate narrow roads or tight campsites. Skip it if your primary goal is ride comfort or chucking reduction.
- Rotating design provides up to 10 inches of offset for tight turns.
- Eliminates cab-to-trailer contact in sharp maneuvers.
- Easy to install; uses existing bolt holes.
Pros: Greatly improves turning radius in tight campgrounds.; Simple mechanical design with no air or electronics.
Cons: Does not reduce chucking; can be noisy when rotating.
4. Lippert Components Revolution Pin Box: Best Budget Upgrade
The Lippert Revolution is a basic solid pin box that serves as a direct replacement for worn or damaged OEM units. It is inexpensive and easy to install, but offers no ride improvement. Based on spec sheets, it meets standard safety requirements, but owner feedback indicates it does not reduce chucking.
This is a good choice if you just need a replacement on a budget and don’t prioritize ride quality. Skip it if you want to reduce noise and vibration in the cab.
- Standard solid design with grease zerk for maintenance.
- Direct replacement for most OEM pin boxes.
- Durable steel construction with black powder coat.
Pros: Very affordable compared to air or rubber models.; Simple and reliable; no moving parts.
Cons: No shock absorption; chucking remains similar to stock.
5. Demco Hijacker Autoslide Pin Box: Best for Autoslide Hitches
The Demco Hijacker Autoslide Pin Box is engineered to work with Demco’s autoslide hitches, automatically moving the pivot point forward during turns. This prevents trailer-to-cab contact without manual intervention. In our evaluation, it performs reliably with the matching hitch, but is not compatible with other brands.
This is the right choice if you already own or plan to buy a Demco Hijacker autoslide hitch. Skip it if you use a different hitch brand.
- Designed specifically for use with Demco Hijacker autoslide hitches.
- Allows the hitch to slide forward automatically in tight turns.
- Durable construction with replaceable wear parts.
Pros: Seamless integration with Demco autoslide systems.; Enhances safety by preventing cab contact.
Cons: Only works with Demco Hijacker hitches; limited compatibility.
6. Curt Manufacturing A16 Adjustable Pin Box: Best Adjustable Height
The Curt A16 pin box allows you to adjust the height of the trailer’s connection point, which is useful when switching between trucks with different bed heights. It is a solid steel unit with no moving parts for ride smoothing. Owner feedback notes that it does not reduce chucking and may creak under load.
This is a practical choice if you need height adjustability on a budget. Skip it if ride comfort is a priority.
- Four height adjustment settings to level trailer.
- No welding; bolts to existing frame holes.
- Includes all necessary hardware.
Pros: Helps level the trailer when truck bed height varies.; Simple adjustment with common tools.
Cons: No cushioning; can be noisy and transmit vibrations.
7. Fifth Wheel Air Ride Pin Box 20K: Best Heavy Duty Air Ride
This heavy-duty air ride pin box is built for large fifth wheels, using dual air bags to absorb road impacts. Based on aggregated owner feedback, it significantly reduces chucking and vibration even with heavy trailers. However, installation requires routing air lines and securing the air bags properly. Some users reported difficulty in achieving perfect alignment.
This is the top choice for owners of heavy fifth wheels who want the best ride quality. Skip it if you have a lighter trailer or are not comfortable with air systems.
- High capacity air bag for heavy fifth wheels up to 20,000 lbs.
- Dual air bag system for redundancy and better damping.
- Includes pressure gauge and inflation kit.
Pros: Handles heavy loads with excellent ride quality.; Dual bags add safety margin.
Cons: Higher cost and more complex installation.
Frequently Asked Questions
What does a fifth wheel pin box do?
The pin box connects the fifth wheel trailer to the hitch in the truck bed. It transfers the trailer’s weight and towing forces, and can also absorb road shocks to reduce chucking and improve ride comfort.
How do I know which pin box fits my fifth wheel?
Check your trailer’s kingpin size (usually 2-5/8 inches) and the bolt pattern on the trailer frame. Most pin boxes are universal fit, but verify the weight capacity matches or exceeds your trailer’s pin weight.
Can I install a pin box myself?
Yes, most pin boxes bolt directly to the trailer frame using existing holes. Basic tools like a torque wrench and socket set are needed. Always follow the manufacturer’s torque specifications.
Will a pin box stop chucking completely?
No pin box eliminates chucking entirely, but air ride and rubber shear spring models significantly reduce it. Solid pin boxes offer little to no improvement over stock.
Do I need a special pin box for an auto-slide hitch?
Some auto-slide hitches require a compatible pin box (e.g., Demco Hijacker). Always check the hitch manufacturer’s recommendations to ensure proper function and safety.
