About this item

  • HEAVY-DUTY TOWING. This high-strength trailer hitch pin is tested and rated for a capacity of up to 21,000 lbs. gross trailer weight. This makes it well-suited for a variety of heavy-duty towing applications
  • ERGONOMIC ACCESS. Instead of a single hole, the grooved head of this trailer pin allows the hitch clip to be inserted at any perpendicular angle. It is easier to use and more ergonomic to install whenever needed
  • VERSATILE. The 5/8-inch diameter of this hitch pin is compatible with any heavy-duty ball mount or other hitch accessories with a 2-1/2-inch or 3-inch shank and 5/8-inch pin hole, making this hitch pin a perfect fit for the largest of class 5 hitches
  • EASY TO GRIP. The 105-degree bend in this trailer hitch pin creates a useful handle for easier use and allows the pin to stay securely engaged in the trailer hitch and ball mount
  • CORROSION-RESISTANT. Protected by a durable zinc-plated finish, this all-steel tow hitch pin offers superior strength and maintains excellent resistance to rust and corrosion for longevity and hassle-free use every time


Whatever type of load you are hauling, having towing equipment that can work as hard as you do is a must. For the most heavy-duty towing jobs, this CURT 5/8" hitch pin packs an extra punch. It is constructed with an extended length, from high-strength steel and is tested to 21,000 lbs. to be compatible with 3" x 3" trailer hitches. The thorough testing done on this hitch pin allows it to keep up with these heavy-duty hitches and tow the heaviest of trailers. This hitch pin is able to fit any 3" x 3" receiver with a 5/8" diameter pin hole. It also features a durable zinc-plated finish to outlast rust, and it has a grooved tip to make inserting the retainer clip easy, from any angle. This package includes both the hitch pin and clip.

I bought this to replace the OEM hitch pin on my 3/4 ton pickup. The OEM pin had its 21,000 lb rating stamped on the pin. This Curt pin fits well and was one of the few that I found that claim to be rated and tested for a 21,000 lb load, matching the original equipment. Amazon's product description says it is aluminum. It is not aluminum. It is zinc-plated high-strength steel.

This fits the new Ford Super Duty pickups with the 3" receiver hitch. Has the necessary 21,000lb rating that Ford says to use.
