Gooseneck Hitches – RV Trader Accessories Store

A gooseneck hitch is a specific piece of equipment with a specific job: mounting a ball inside the truck bed, over the rear axle, to connect a gooseneck trailer or adapt a fifth wheel. It's not a standard bumper receiver setup, and buying the wrong hardware - wrong ball size, wrong coupler style, wrong configuration for your trailer - creates real problems before you ever leave the driveway.

Every gooseneck hitch component in this collection comes from Rigid Hitch, which sources from brands like B&W, Demco, Bulldog, Blaylock, Husky Towing, and Convert-A-Ball - names that towing professionals and heavy haulers actually rely on. These aren't budget import parts. They're built for trucks doing serious towing work.

What Is a Gooseneck Hitch?

A gooseneck hitch is a towing system that mounts a ball inside the truck bed rather than at the bumper. The trailer's coupler - a tube that extends forward from the trailer frame - drops down over the ball from above, placing the hitch point directly over the rear axle. That geometry gives gooseneck setups their signature stability at high weights and is why they're the standard for livestock trailers, flatbed equipment trailers, and heavy cargo haulers.

The core components are an underbed mounting system (typically vehicle-specific brackets that bolt to the truck frame) and a removable hitch ball that installs flush with the truck bed when not in use. Most quality setups - including B&W's popular Turnoverball system - allow the ball to fold down or remove completely so the bed stays functional.

Gooseneck towing is rated well above standard fifth wheel or receiver hitch setups. Trucks properly equipped for gooseneck towing typically see capacities in the 25,000-30,000+ lb GTW range, depending on the truck's own tow rating.

Gooseneck vs. Fifth Wheel: What's the Difference?

Both systems tow from inside the truck bed, but they use different connection hardware on the trailer side.

A gooseneck trailer has a coupler - a tube or neck that extends from the trailer and drops over a 2-5/16" ball inside the bed. The connection is simple and handles extreme weights well, which is why livestock and equipment trailers almost universally use gooseneck design.

A fifth wheel trailer uses a kingpin - a metal pin that locks into a fifth wheel hitch head (the horseshoe-shaped coupling device bolted in the bed). Fifth wheel setups are the standard for residential RV trailers: travel trailers with fifth wheel configurations, toy haulers, and luxury coaches.

If you have a gooseneck hitch and want to pull a fifth wheel trailer, you need an adapter - specifically a gooseneck-to-kingpin adapter. This collection carries several options, including cushioned adapters designed to reduce vibration transfer between the truck bed ball and the fifth wheel kingpin. If you have a fifth wheel hitch and want to pull a gooseneck trailer, the reverse adapter is a gooseneck coupler that connects to your fifth wheel kingpin.

Types of Gooseneck Hitch Components

Underbed Hitches and Mounting Systems

The underbed portion is the foundation of any gooseneck setup - vehicle-specific mounting brackets that bolt to the truck frame and accept the hitch ball from above. B&W's Turnoverball system is one of the most widely installed designs on diesel trucks, allowing the 2-5/16" ball to flip down into a flush position when not needed. This collection also carries Husky Towing fifth wheel rail mount base kits and B&W replacement installation brackets for Chevy/GMC 2500 and 3500 applications (model years 2011-2019).

If you're starting a new gooseneck installation, confirm that your underbed bracket system is rated to match both your truck's tow capacity and the trailer's GTW.

Gooseneck Couplers

The coupler is the trailer-side component - the tube or neck that drops over the ball. This collection carries:

• Round tube couplers - the most common configuration for standard gooseneck trailers, available in 30,000 lb GTW ratings from Rigid Hitch and Demco
• Square tube couplers - used on specific trailer designs; the Bulldog kingpin gooseneck coupler with round tube covers heavy-duty livestock and equipment applications
• Locking couplers - B&W's Defender series adds a locking mechanism to the coupler sleeve, preventing unauthorized connection or theft of the trailer. Available in inner-tube-only (GNC4250) and full sleeve configurations (GNC4251)
• Offset couplers - B&W's Extend-A-Goose (TEXA4200) adds a 10" offset, useful when the trailer's neck geometry requires clearance adjustment

Hitch Balls

Gooseneck applications use a 2-5/16" ball as the standard. This collection carries a 3-inch gooseneck hitch ball for specialty applications - confirm your coupler's ball pocket size before ordering. Standard 2-5/16" balls are included in several kit configurations.

Gooseneck-to-Fifth Wheel Adapters

For pulling fifth wheel RV trailers with a gooseneck hitch, cushioned coupler adapters are the right setup. Two configurations are available:

• Height-adjustable cushioned adapter - mounts between the gooseneck ball and the fifth wheel kingpin with built-in rubber cushioning to absorb road vibration. Adjustable height accommodates different trailer nose heights.
• 7-1/2" offset cushioned adapter - same cushioned design, adds horizontal offset for trailers requiring clearance adjustment

Gooseneck-to-Kingpin Adapters

The reverse scenario - pulling a gooseneck trailer with a fifth wheel hitch. These adapters replace the kingpin with a gooseneck coupler, converting the fifth wheel coupling point to accept a ball. Available in standard and 3-inch ball configurations.

Security and Locks

Blaylock makes three styles of gooseneck coupler locks in this collection: a standard coupler lock, an adjustable sleeve lock, and a RAM Security gooseneck-style lock. Each is designed to prevent the coupler from engaging with the ball, acting as both a theft deterrent and a secondary safety measure.

Hitch Pins

Latch pins for BX1 gooseneck couplers and hitch pin sets are available for replacement or spare hardware.

How to Choose the Right Gooseneck Hitch Setup

Match to your truck's tow rating first. The lowest-rated component in your towing system limits the whole setup. A 30,000 lb rated coupler does nothing if your truck is rated for 18,500 lbs. Check your truck's actual gooseneck tow rating - not just the receiver or fifth wheel rating, but the specific gooseneck or bed-hitch capacity listed in your owner's manual. On most heavy-duty trucks (F-250/350, Ram 2500/3500, Silverado/Sierra 2500/3500), this is where you'll find the highest capacity numbers.

Know your trailer's coupler style and GTW. Gooseneck trailers typically use either a round tube or square tube coupler over a 2-5/16" ball. Confirm the coupler tube shape, the ball pocket size, and the trailer's fully loaded GTW before selecting hardware.

Decide on the ball setup. If you want bed access when not towing, a removable or fold-down ball is worth it. If the truck is a dedicated tow rig, a fixed setup simplifies things.

Adapters for fifth wheel trailers. If your goal is pulling a residential RV fifth wheel, a cushioned gooseneck-to-kingpin adapter is the right connection point. Look for an adapter with adequate GTW rating for your trailer and height adjustability to keep the trailer level.

Gooseneck Hitch Installation

Installing a gooseneck underbed system is a significant job - it typically involves drilling through the truck bed, running cross-tubes under the bed, and bolting the bracket system to the truck frame. Most installations are done by shops or experienced DIYers with access to a lift or floor jack and proper torque specs for the specific bracket kit.

A few things that matter across any gooseneck install:

• Use vehicle-specific brackets. Universal kits require drilling and fitting that introduces more variables. Truck-specific kits from B&W or comparable brands use factory frame holes on many applications, reducing modification.
• Torque hardware to spec. The mounting hardware anchoring the underbed assembly to the frame is critical. Follow the manufacturer's torque sequence and values from the install sheet.
• Confirm ball height after installation. The ball should sit at the correct height for your coupler. Most gooseneck couplers operate in a relatively forgiving range, but an extreme height mismatch puts stress on the coupler and the neck of the trailer.
• Test before loading. Hitch the trailer unloaded, verify the coupler is fully seated and locked, drive a short distance, then re-check before putting on a full load.

If you're not confident in a DIY install, a truck upfitter or hitch shop can handle it. Installation typically runs $200-$500 in labor depending on the truck and how much bed modification is involved.

FAQ

What is a gooseneck hitch? A gooseneck hitch is a towing system that mounts a 2-5/16" ball inside the truck bed, over the rear axle. The gooseneck trailer's coupler - a forward-extending tube or neck - drops over the ball from above. This design places the tow point over the axle for stability and handles much higher weight ratings than standard bumper receiver hitches.

What is a gooseneck trailer hitch? A gooseneck trailer hitch refers to the complete system: the underbed mounting brackets, the ball, and the coupler on the trailer side. The term is sometimes used interchangeably with "gooseneck hitch" but technically includes the trailer coupler as part of the connection.

How does a gooseneck hitch work? The underbed assembly anchors to the truck frame and holds a 2-5/16" ball that sits in or slightly above the truck bed surface. The trailer's gooseneck coupler - a tube extending forward from the trailer frame - lowers onto the ball and locks in place. Safety chains attach separately. The over-axle connection point distributes tongue weight more effectively than a rear receiver hitch, enabling the high GTW ratings gooseneck systems are rated for.

Can you pull a fifth wheel with a gooseneck hitch? Yes - with an adapter. A gooseneck-to-fifth wheel cushioned coupler adapter connects the truck's gooseneck ball to the fifth wheel trailer's kingpin. This collection carries height-adjustable and offset cushioned adapter options rated for RV fifth wheel applications. The cushioning in quality adapters reduces vibration compared to a rigid metal-to-metal connection.

Are gooseneck hitches universal? No. Underbed mounting systems are vehicle-specific - B&W, CURT, and other manufacturers produce bracket kits matched to individual truck years and models. The coupler on the trailer side is also specific to the trailer's tube size and configuration. The 2-5/16" ball is the universal connection point, but everything around it is application-specific.

Can you install a gooseneck hitch yourself? It depends on your mechanical experience and available tools. Vehicle-specific kits that use factory frame holes are more DIY-accessible. Kits requiring bed drilling or extensive frame access are better done by a shop. Either way, precise torque values and correct bracket positioning are non-negotiable for safety.

How much does it cost to install a gooseneck hitch? Hardware varies widely by configuration - couplers and balls run from around $80 to $800+ depending on style and rating; underbed systems from complete B&W kits typically run $400-$900. Installation labor at a hitch shop or truck upfitter typically adds $200-$500 depending on the vehicle and complexity. Budget $600-$1,400 total for a complete new installation on a standard heavy-duty truck.

How much does a gooseneck hitch weigh? A typical underbed assembly (cross-tube, brackets, and ball) runs 40-80 lbs depending on design. Couplers are 15-60 lbs depending on style and rating. This is a relevant consideration for keeping overall tongue weight within rated limits on lighter trucks.

Can you put a gooseneck hitch in a short bed truck? In most cases, yes - short bed (6.5') and standard bed trucks both support gooseneck hitches using vehicle-specific underbed kits. The concern with short beds is trailer turn clearance: the trailer neck needs enough room to swing without hitting the cab during tight turns. This is more of a factor with certain fifth wheel adapter setups than with purpose-built gooseneck trailers, which are typically designed with enough neck length for short-bed clearance.

Can you remove a gooseneck hitch? The ball can be removed or flipped flush with B&W Turnoverball-style systems, keeping the truck bed functional. The underbed bracket and cross-tube assembly is typically semi-permanent - it can be unbolted but it's not designed for daily removal. Most gooseneck tow truck owners leave the underbed hardware in place and simply remove the ball when not in use.
