1. B&W Trailer Hitches Companion RVK3300: Best Overall
The B&W Companion RVK3300 is a top-tier king pin hitch that excels in durability and ease of use. Based on owner feedback and the spec sheets, its turnover ball design is a standout feature, allowing the truck bed to remain flat when the hitch is not in use. The patented latching mechanism provides a secure connection, and the powder-coated finish resists rust. In our evaluation, this hitch is ideal for heavy-duty towing with a 30,000 lb GTW rating.
However, the premium construction comes at a higher price point, which may not suit budget-conscious buyers. Additionally, the installation requires drilling into the truck bed, which might be a drawback for those who prefer no-drill options. If you tow infrequently or have a lighter trailer, a simpler, less expensive hitch may suffice.
- Turnover ball design allows full truck bed use when not towing
- Patented latching system ensures secure connection
- Includes installation kit with clear instructions
Pros: Very high build quality and corrosion resistance; Easy to remove and install without tools
Cons: High initial investment compared to basic models
2. Curt Manufacturing Q20 20K Gooseneck Hitch: Best Value
The Curt Q20 offers a great balance of performance and affordability. We compared its specifications against industry standards and found it to be a reliable choice for mid-duty towing. The no-drill installation is a major plus for DIYers, and the adjustable height helps achieve a level trailer. Owner feedback highlights its sturdy construction and ease of use.
That said, its 20,000 lb GTW rating is lower than some heavy-duty options, so it may not be suitable for the largest trailers. Some users reported that the paint finish can chip over time. If you need to tow more than 20,000 lbs regularly, consider a higher-capacity model.
- No-drill installation with pre-assembled base rails
- Adjustable ball height for level towing
- Safety chain attachment points included
Pros: Excellent value for the capacity and features; Quick and straightforward installation process
Cons: Lower weight capacity than some competitors
3. PullRite SuperGlide 18K: Best for Maneuverability
The PullRite SuperGlide is designed for those who frequently navigate tight turns or have short-bed trucks. Based on owner feedback, the automatic sliding feature is highly valued for preventing cab contact. We evaluated its performance against safety standards and found it to be a reliable system. The construction is robust, though the added mechanism increases weight.
However, the complexity can lead to higher maintenance and potential issues over time. Some users noted that the sliding mechanism can be noisy. If you have a long-bed truck or rarely make sharp turns, a simpler fixed hitch might be more practical.
- Automatic sliding mechanism prevents cab contact during tight turns
- No need to manually adjust hitch position
- Compatible with most gooseneck trailers
Pros: Enhances maneuverability in tight spaces; Reduces risk of trailer-cab collision
Cons: Heavier and more complex than fixed hitches
4. Demco Hijacker Autoslide 20K: Runner Up
The Demco Hijacker Autoslide is a strong competitor to the PullRite, offering similar automatic sliding capabilities. In our evaluation, its locking pins provide a secure connection, and the 20,000 lb capacity covers a wide range of trailers. Owner feedback praises its smooth operation and the clean installation with under-bed rails.
However, some users reported that the installation instructions were not very clear, leading to a longer setup time. The sliding mechanism also adds weight. If you prefer a simpler setup, a fixed hitch might be better.
- Automatic sliding mechanism with locking pins
- Fits under-bed rails for a clean look
- Includes safety chain anchors
Pros: Smooth sliding action and secure lock; Good weight capacity for most heavy trailers
Cons: Installation can be challenging for some users
5. Reese Goosebox 20K: Best for Fifth Wheel Conversion
The Reese Goosebox is a specialized product that converts a fifth wheel trailer to a gooseneck hitch. We researched its specifications and found the air ride dampening to be a unique feature that enhances comfort. Owner feedback indicates it works well for those who already own a fifth wheel and want to use a gooseneck setup.
However, it is not a standalone king pin hitch for standard gooseneck trailers. The conversion adds weight and complexity. If you don’t have a fifth wheel, this product is not suitable. Also, some users reported that the air bag system requires occasional maintenance.
- Converts fifth wheel trailer to gooseneck
- Built-in air ride dampening for smoother towing
- Includes all necessary hardware
Pros: Air ride reduces shock and vibration; Simplifies switching between hitch types
Cons: Not for use with standard gooseneck trailers
6. Bullet Proof Hitches BPHD20K: Heavy Duty Choice
The Bullet Proof Hitches BPHD20K is built for maximum durability. Based on the spec sheet and owner feedback, its all-steel construction and powder coat finish make it resistant to rust and wear. It is a fixed hitch, which means no moving parts to fail, and it can handle heavy loads reliably.
However, the lack of adjustability means you cannot change ball height or use a sliding mechanism. This limits its versatility, especially for short-bed trucks. It is also heavier, making installation more labor-intensive. If you need a hitch that can adapt to different trailers, consider a more adjustable model.
- All-steel construction with heavy-duty powder coat
- Fixed design with no moving parts
- Includes installation kit and instructions
Pros: Extremely durable and long-lasting; Simple, reliable design
Cons: No adjustability or sliding feature; Heavier than some competitors
7. PopUp G2 16K Gooseneck Hitch: Budget Pick
The PopUp G2 is a budget-friendly option for those with lighter trailers. We compared its specifications to industry standards and found it adequate for occasional towing up to 16,000 lbs. Owner feedback highlights its low price and ease of installation, but also notes that the finish is not as durable as premium models.
However, its lower capacity and potential for rust make it less suitable for heavy or frequent use. The lack of advanced features like automatic sliding or height adjustment may be a drawback. If you tow heavy loads regularly, we recommend investing in a higher-quality hitch.
- Affordable price point for light to medium duty
- Removable ball for bed clearance
- Basic installation with included hardware
Pros: Low cost makes it accessible; Lightweight and easy to handle
Cons: Lower weight capacity and durability; Some users report rust after extended use
Frequently Asked Questions
What is a king pin hitch for gooseneck trailers?
A king pin hitch is the coupling device that connects a gooseneck trailer to a tow vehicle. It typically consists of a ball and socket mechanism that allows articulation. The king pin is the vertical pin on the trailer that fits into the hitch.
How do I choose the right weight capacity for my king pin hitch?
You should select a hitch with a Gross Trailer Weight (GTW) rating that exceeds the loaded weight of your trailer. Also consider the vertical load rating (pin weight). It’s recommended to have a safety margin of at least 10-20% above your trailer’s weight.
Can I install a king pin hitch myself?
Many hitches come with installation kits and instructions, but the difficulty varies. No-drill models are easier for DIYers. However, some hitches require drilling into the truck bed or frame. If you are not comfortable with mechanical work, professional installation is advised.
What is the difference between a fixed and sliding gooseneck hitch?
A fixed hitch has a stationary ball, while a sliding hitch can move forward and backward to prevent the trailer from contacting the cab during sharp turns. Sliding hitches are beneficial for short-bed trucks but are more complex and heavier.
Do I need a king pin hitch with built-in shock absorption?
Built-in shock absorption (like air ride) can reduce road vibrations and improve towing comfort, but it is not necessary for all users. It adds cost and maintenance. If you tow on rough roads or want a smoother ride, it may be worth it.

After our research and comparison, the B&W Trailer Hitches Companion RVK3300 stands out as the top pick for its exceptional build quality, ease of use, and high weight capacity. For those seeking a balance of price and performance, the Curt Manufacturing Q20 is an excellent runner-up.
