CURT Combo Pintle Hook and 2-5/16" Trailer Ball — 20,000 lb Capacity, Forged Steel

The CURT 48012 is a receiver-mounted combination pintle hook and 2-5/16" trailer ball rated to tow up to 20,000 pounds at the ball, built for heavy-duty trucks and trailers.

If you need a versatile, robust towing solution for construction, farming, utility, or commercial work, this CURT combo hitch gives you both a pintle coupling and a conventional trailer ball in one compact receiver-mounted unit. It slides into a standard 2-1/2" x 2-1/2" hitch receiver and is engineered to handle rugged use while resisting rust and abrasion with a protective finish.

How does this combo hitch give me more towing flexibility?

The 48012 integrates a pintle hook and a 2-5/16" trailer ball so you can connect either lunette-ring trailers or standard coupler trailers without swapping hardware. That dual-function design eliminates the need to carry separate hitches for different trailer types.

• Accepts lunette rings with 2-1/2" or 3" inner diameters
• Works with standard 2-5/16" couplers at the trailer ball
• Instantly converts between pintle and ball towing modes
• Mounts into a 2-1/2" x 2-1/2" receiver tube for quick installation

How strong and durable is the 48012 under heavy use?

CURT built this unit from forged steel to withstand frequent heavy towing and shock loads common in off-road, farm, and commercial environments. The assembly includes a spring-loaded locking arm to keep the pintle engaged and a chrome-plated ball for corrosion resistance where it contacts the trailer coupler.

• Forged-steel construction for high tensile strength and toughness
• Spring-actuated locking arm for positive pintle retention
• Black powder coat finish to resist scratches and surface corrosion
• Chrome-plated ball surface for smooth coupling and rust protection

What are the capacity limits and safety considerations?

The trailer ball portion of this combo is rated to 20,000 pounds. Always verify the lowest-rated component in your towing system — vehicle, hitch receiver, ball mount, and trailer — before hauling to ensure safe operation. The pintle arrangement is intended for heavy-duty and off-road towing where higher strength and tolerance for movement are needed.

• Ball capacity: 20,000 lb (do not exceed the lowest-rated system component)
• Pintle fits lunette rings with 2-1/2" or 3" inside diameter
• Designed for installation in 2-1/2" x 2-1/2" receiver tubes
• Regular inspections and lubrication recommended for long life

How simple is installation and routine maintenance?

Installation is straightforward: slide the shank into a compatible receiver and secure with a standard 5/8" hitch pin and clip (not included). Maintenance consists of keeping mating surfaces clean, checking the locking mechanism for wear, and touching up the finish if heavy abrasion exposes bare metal.

• Installs into a standard 2-1/2" receiver tube with common hitch pin
• Inspect locking arm, latch, and ball before each tow
• Clean and lightly lubricate moving parts to prevent binding
• Reapply rust-inhibiting coatings if finish is compromised

Who is this for: The CURT 48012 is aimed at owners and operators who need dependable, heavy-capacity towing without carrying multiple hitch heads — contractors, farmers, municipal fleets, and off-road haulers who switch between lunette-eye trailers and conventional coupler trailers. If you run a Class 5 hitch setup and require a rugged combination that fits a 2-1/2" receiver, this model provides both the strength and the flexibility for demanding work-site towing. Remember to match the hitch to your vehicle and trailer ratings and never exceed the lowest-rated component in your towing chain.
