/ From the comments

They looked it up.

YouTube comments on Dirt Monkey’s video, September 2026

  • I was bashing the price but I just looked it up. It is the highest quality titanium, it's not the cheap stuff. He's using the best product.

    @Drewdayz2419
  • We all get mad at companies cheaping out on us, but the guy is literally using the best quality titanium made, and everybody on here is clowning him for being too expensive.

    @Drewdayz2419
  • It is titanium, which work hardens quickly and tends to gunk up grinding and flap discs pretty good. It's gonna take more than you think.

    @Jester_The_Jynxster
  • That thing is sick. I'm going to get one for the truck!

/ WHY THIS PIN

Built the right way.

MECHANISM

Push the button. No R-clip.

A patented push-button mechanism that goes in-line with the pin — open it with one hand, close it with one hand. Replaces the wobbly R-clip with a single click. Goodbye scraped knuckles.

MATERIAL

6AL4V Titanium.

Aerospace-grade Ti-64 titanium that won't rust through a season of road salt. Lighter than steel, stronger than chrome — built once, lasts a lifetime.

FIT

Class III, IV, V receivers.

5/8" pin diameter with a 3.6" grip length. Drops into any standard 2, 2½, or 3" receiver across pickups, SUVs, and tow rigs.

WARRANTY

90 days. Lifetime. No fight.

A 90-day Knuckle-Saver Guarantee — return it for a full refund if it doesn't change your day. Backed by a lifetime warranty against defects.

/ Salt proof

1,000

A full season of road salt. Compressed into six weeks.

ASTM B117 salt spray. 1,000 hours of continuous saltwater mist. PinUltimate came out pristine. Same as day one. The pin is 6AL4V titanium and so are the three positive locking balls, so there is nothing on it to rust.

Covered for life against premature corrosion and mechanism failure.

Titanium Salt Bath Test
★★★★★
Replaced my R-clip after one too many parking-lot fumbles. This thing just works. Three winters hauling a horse trailer through Montana road salt and it still looks new.

/ Questions

Straight answers.

Why titanium?

Because it never rusts. The pin is heat-treated 6AL4V titanium. There is nothing on it for salt to eat. The handle is aircraft-grade anodized aluminum, machined on a CNC.

Will it seize up in road salt?

No. We ran it through 1,000 hours of ASTM B117 salt spray, continuous saltwater mist, and it came out the same as day one. The pin is titanium and so are the three positive locking balls that hold it in. Salt has nothing to grab.

Is it greaseable? Does it need maintenance?

No grease. Nothing to grease. Wash it when you wash the truck and dry it off. Every so often, give the lock cylinder a shot of WD-40. That is the whole list.

Why does it cost $170?

Titanium costs more than steel. So does machining in Manhattan, Montana instead of importing. You are buying once. The pin never rusts, the lock is built in, and it is covered for life. If it does not earn its keep in 90 days, send it back for a full refund.

Can someone just steal my hitch?

The lock is built into the pin and takes a bidirectional key. No padlock hanging off the back to snap. Nothing is theft-proof. This makes your hitch the hard target.

What does it fit?

Class III, IV and V receivers: 2-inch, 2.5-inch and 3-inch. It is a 5/8-inch pin with a 3.6-inch grip.

What is the warranty?

Lifetime. That covers material defects, failure of the push-button mechanism, and premature corrosion of the titanium or stainless parts. No charge, and we cover the return shipping. On top of that is the 90-day Knuckle-Saver guarantee: if you do not love it, send it back within 90 days for a full refund.
