/ WHY THIS PIN

Built the right way.

DESIGN

Anti-theft Zero-Gap.

We didn't leave room for a thief to wedge in a tool. The lock seats flush against the coupler, no gap, no leverage point.

MATERIAL

17-4 stainless + alloy.

Heat-treated 17-4 stainless steel and 6061 aircraft-grade aluminum. Sealed against weather, ready after years in salt and road grime.

KEY

Bidirectional. One-key.

The bidirectional key works either way you insert it. Order keyed-alike to your PinUltimate Hitch Pin and one key operates both.
