Product Details

The HAZET 40005 is a heavy-duty 2-5/16-inch chrome trailer hitch ball engineered for demanding towing applications. Constructed from high-strength hot-forged steel and finished with a durable nickel-chrome plating, this tow ball is built to withstand the rigors of regular, heavy-load hauling.

With a 7,500 lb. gross trailer weight capacity, this trailer ball is well-suited for towing heavy receiver-style trailers including dump trailers, toy haulers, farm equipment trailers, dual-axle utility trailers, and large RVs. The 2-5/16-inch ball diameter fits standard 2-5/16-inch couplers commonly used on larger Class III, IV, and V trailer setups.

Key Features:

  • Ball Diameter: 2-5/16 inches — fits standard 2-5/16" couplers
  • Gross Trailer Weight (GTW) Capacity: 7,500 lbs.
  • Shank Diameter: 1 inch
  • Shank Length: 2-1/8 inches
  • Hot-forged, high-strength steel construction
  • Durable nickel-chrome finish for corrosion resistance
  • Fine threads on shank for superior holding strength (250 lb.-ft. torque required)
  • Includes zinc-plated hex nut and helical lock washer for secure mounting
  • Tested to meet U.S. VESC V-5 safety specifications

Installation Note: The mounting platform must be at least 3/8" thick, and the mounting hole must not exceed 1/16" larger in diameter than the threaded shank. Always ensure all towing components are rated at or above the intended load — never exceed the lowest weight rating of any component in the towing system.
