5/8 Trailer Hitch Lock for Class III IV Hitches

The extra-long 5/8" diameter locking hitch pin with a maximum active length of 3-1/4" is designed to fit Class III/IV hitches with 2" and 2-1/2" receivers. This solid, hardened steel tow hitch lock pin features a black e-coated finish on a zinc-plated surface. Before making a purchase, please verify all the dimensions of your hitch to ensure a proper fit for the hitch lock pin.

A separate spring clip (cotter pin) provides additional safety, allowing you to use the locking pin with or without the lock mechanism. Caution: The spring clip (cotter pin) MUST be inserted into the pin hole when using this lock.

Rubber O-rings prevent any rattling and hold the hitch pin firmly in place. Please note that different brand hitches may have slightly varying hitch tube sizes, so it may be necessary to adjust the O-ring quantity or remove the O-ring to achieve the perfect fit for the receivers.

The push-lock design with 2 tubular keys makes it easier to lock and unlock the system. The 1/4 turn lock and push-lock mechanism are easy to operate, and the watertight dust rubber cap helps prevent internal corrosion of the locking mechanism.
