If you need a 3-inch gooseneck ball rated near 40,000 pounds, the listed options top out at 38,000 pounds, so none is rated for 40,000 pounds. The CURT OEM puck-system ball is best for select factory puck setups, while the raised FlexHitch ball is for compatible square-base underbed receivers. The other options offer lower ratings or a different ball diameter. Confirm your truck system, coupler size, and required ratings before choosing.

CURT OEM Puck System 3-Inch Ball
This CURT ball is rated for 38,000 pounds of gross trailer weight and 9,500 pounds of vertical load. Its 3-inch ball and quarter-turn latch are intended for compatible factory puck systems. The listed fitment names select systems and the Nissan Titan XD, but the supplied fitment details are incomplete; verify the exact vehicle and puck configuration before ordering.
Best for: Owners with a compatible OEM puck system who need a 3-inch ball close to, but below, a 40,000-pound target. The quarter-turn latch supports straightforward installation and removal. Limitation: Its 38,000-pound rating is not a 40,000-pound rating, and it will not fit every truck or hitch system.
CURT 40089 3-Inch Trailer Hitch Ball
The CURT 40089 is a 3-inch tow ball designed for 3-inch couplers. It accepts up to 30,000 pounds of gross trailer weight and has a 2-inch-by-3-1/4-inch shank. The ball is made from high-strength raw steel and heat-treated for wear resistance.
Best for: Buyers who need a standalone 3-inch ball for a compatible 3-inch coupler and whose required rating is no more than 30,000 pounds. Its listed coupler fit and shank dimensions help identify the intended application. Limitation: It is rated lower than the 38,000-pound options and is not described as an OEM puck-system kit. Check the hitch mounting requirements separately.
FlexHitch Raised 3-Inch Gooseneck Ball
This raised 3-inch gooseneck ball is listed at 38,000 pounds and is made for an underbed gooseneck hitch with a square-base receiver. Its features include a reinforcing rib structure, pre-drilled safety-chain holes, and four anti-tilt polyurethane washers. The listing says washers can be selected according to need and describes their role in limiting movement between parts.
Best for: Buyers whose underbed hitch uses the specified square-base receiver and who want a raised 3-inch ball with anti-tilt washer features. Limitation: The listing explicitly says it is not for a puck system. Confirm the receiver style before purchase; its 38,000-pound rating is also below 40,000 pounds.
60692 30K OEM Puck System Kit
This kit has a 2-5/16-inch ball rated for up to 30,000 pounds GTW and 7,500 pounds vertical load. The listed applications include select 2013–2027 Ford Super Duty trucks and select 2016–2026 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD models equipped with a factory puck system. The product details emphasize that the factory prep package is required.
Best for: Drivers with a listed compatible truck who need a 2-5/16-inch ball and a rating within the kit’s limits. Limitation: This is not a 3-inch ball and is rated at 30,000 pounds, so it does not match a 3-inch, 40,000-pound requirement.
60639 38K OEM Puck System Kit
The 60639 kit is listed at 38,000 pounds GTW and 9,500 pounds vertical load. It uses a 2-5/16-inch ball and is designed for factory-installed OEM puck systems. Listed fitment includes select 2013–2026 Ford F-250, F-350, and F-450 Super Duty; 2016–2026 Chevy Silverado and GMC Sierra 2500HD and 3500HD; and 2016–2026 Nissan Titan XD models. Its quarter-turn latch is described as tool-free.
Best for: A buyer with a listed truck and puck system who wants a higher-rated alternative to the 30K kit and does not need a 3-inch ball. Limitation: Its 2-5/16-inch diameter does not meet a 3-inch ball requirement, and its rating remains below 40,000 pounds.
Buying Guide: How to Choose a Gooseneck Ball
Does the ball need to be exactly 3 inches?
Match the ball diameter to the trailer coupler specification. A 3-inch ball and a 2-5/16-inch ball are different sizes and should not be treated as interchangeable. The 60692 and 60639 kits have 2-5/16-inch balls, while the CURT 40089, CURT puck-system ball, and FlexHitch product are listed as 3-inch options.
How much towing capacity do you need?
Compare the product’s gross trailer weight rating with the trailer’s loaded weight, and check the vertical-load rating where provided. The products listed here are rated at 30,000 or 38,000 pounds—not 40,000 pounds. Do not assume a component is suitable for a 40,000-pound load because it is described as heavy-duty.
Which mounting system does your truck use?
OEM puck-system kits require a compatible factory puck or fifth-wheel prep package. The FlexHitch ball is specifically for an underbed hitch with a square-base receiver and is not for puck systems. The CURT 40089 is described as a ball for 3-inch couplers, so review the hitch’s mounting arrangement before selecting it.
What should you verify before ordering?
Confirm the truck year, make, model, factory hitch preparation, receiver or puck style, ball diameter, and load requirements. Product fitment descriptions can apply only to select configurations. If the trailer, hitch, or truck has a lower rating than the ball, the lower-rated component remains an important limit.
