Customer Reviews
Dave M.
“Swapped out my standard factory pin for this 6000 kg-rated Nyloc setup after noticing my old one starting to show wear marks. The 4140 structural steel is night and day compared to cheap chrome pins. I towed a heavy boat trailer across unsealed roads, and the pin held perfectly with zero signs of elongation or bending. Absolutely essential piece of mind for heavy loads.”
Verified Buyer
“Using this on a 2.5-inch heavy-duty commercial truck receiver to pull equipment trailers. The double-shear load distribution is solid, and the lynch pin backup plus Nyloc nut ensure it can’t vibrate loose on long highway hauls. Fits tightly in the housing, which stops a lot of the obnoxious clunking.”
Verified Buyer
“Incredibly tough pin. I put my hitch setups through a lot of punishment towing large agricultural machinery. This pin hasn’t flinched under massive dynamic pulls. Only dropping one star because the high-tensile material makes it slightly heavier and tighter to line up than standard loose pins, but that’s exactly why it doesn’t break.”
Verified Buyer
“Perfect upgrade for peace of mind. Standard bolts are too brittle for dynamic trailer push-and-pull forces, but this high-tensile pin handles the shifting loads cleanly. Zero rust scaling observed after continuous exposure to salt water at boat ramps. If you are towing anything near or over 3.5 tonnes, don’t risk a cheap pin.”
Frequently Asked Questions
- Which hitch class is this pin compatible with? This pin is engineered for heavy-duty Class 4 and Class 5 receivers with standard 5/8-inch (16mm) pin holes.
- Can this pin handle a 6000kg ATM trailer? Yes, it is rated for an Aggregate Trailer Mass (ATM) up to 6,000 kg and uses high-tensile steel to withstand extreme shear forces.
- Is the hitch pin rust-resistant for marine towing? Yes, it features a heavy-duty chrome- or zinc-plated finish to protect against corrosion, saltwater, and harsh weather conditions.
- Does it include a locking mechanism? This model comes with a heavy-duty spring cotter pin (R-clip), but it can be replaced with a standard 5/8″ hitch lock if security is required.
Usage Guidelines: Do’s & Don’ts
✔️ Do’s
- Verify fitment: Ensure your receiver hitch hole is exactly 5/8 inches (16mm) before installation.
- Check the clip: Always insert the safety R-clip fully into the retaining hole until it clicks into place.
- Inspect regularly: Look for hairline cracks, bending, or excessive wear before every long-distance tow.
- Match your ratings: Ensure your ball mount, hitch receiver, and tow vehicle are all rated to handle the load.
❌ Don’ts
- Do not exceed limits: Never exceed the maximum 6000kg rating, as overloading risks catastrophic shear failure.
- Do not substitute clips: Never use makeshift wires, nails, or worn-out clips instead of the supplied safety pin.
- Do not modify: Avoid grinding, welding, or drilling into the high-tensile steel, which compromises its structural integrity.
- Do not ignore rattle: Never use a loose or mismatched pin that allows excessive shifting inside the receiver.
