📘 Overview
The Kingpin Lock covers the 2 in kingpin on a parked trailer so no tractor can couple to it, which stops the fastest form of trailer theft — someone backing under a dropped trailer and driving away. Installation is a slide and a turn of the key, which matters because a lock that takes two minutes in the rain is a lock that stops being used. At 6.46 x 6.3 x 4.8 in it is compact enough to live in the tractor rather than the yard office. Choose Keyed Differently for a unique key or Keyed Alike to match the five-digit key code already running across your trailers, which is the usual choice for a fleet where any driver may need to release any trailer.
⚙ Key Features of the Kingpin Lock
- Covers the kingpin completely — with the pin enclosed there is no surface for a fifth wheel to grip, so coupling is physically impossible rather than merely difficult.
- Sized for a 2 in kingpin — the standard trailer kingpin dimension, so fitment across a conventional fleet is a known quantity.
- Slide-on installation — it goes on and locks with the supplied key in seconds, which is what makes it get used on every drop.
- Compact 6.46 x 6.3 x 4.8 in body — small enough to carry in the cab and not be forgotten in the yard.
- Barrel-style key cylinder — resists picking, Freon attack and corrosion, and the body is built to take thousands of pounds of force rather than shear off under a pry bar.
- Powder-coated steel throughout — the finish survives being thrown in a truck bed daily and does not rust through a season parked outside.
🔑 Why a Kingpin Lock Stops the Fastest Theft
- Defeats the drive-away — a dropped trailer is stolen by backing a tractor under it, and a covered kingpin makes that impossible without cutting.
- Protects the load and the trailer together — a door lock protects the freight but leaves the trailer itself takeable; the kingpin lock addresses the asset.
- Fast enough for a drop-and-hook operation — the seconds it takes are the reason it survives contact with a real yard schedule.
- One key for the fleet — Keyed Alike means any driver with the fleet key can release any trailer without a key handover.

🚜 Which Trailers Take the Kingpin Lock?
Fitment is decided by the kingpin. The Kingpin Lock covers a 2 in kingpin, the standard dimension on conventional semi-trailers and fifth wheel trailers.
Semi-trailersDrop trailersFifth wheel trailersRV fifth wheelsFlatbedsDry vans
Trailers coupled by a ball or ring hitch rather than a kingpin are secured by the Ball and Ring Hitch Lock instead.
Confirm your trailer uses a 2 in kingpin before ordering. A trailer that couples to a ball, a pintle ring or a receiver hitch needs a different product.
Everything needed to confirm fitment is on this page — add it to your cart to see delivered pricing for your address.
Inspect the shipment before you sign. If the carton or crate arrives damaged, note it on the bill of lading at the time of delivery — that note is what supports a carrier claim, and it cannot be added afterwards.
❓ Kingpin Lock Questions, Answered
What size kingpin does the Kingpin Lock fit?
The Kingpin Lock is made for a 2 in trailer kingpin, which is the standard dimension on conventional semi-trailers and fifth wheel trailers.
How does a king pin lock prevent trailer theft?
The Kingpin Lock covers the kingpin so a tractor fifth wheel has nothing to couple to. Without a coupling the trailer cannot be towed, however quickly someone backs under it.
How long does the Kingpin Lock take to fit?
It slides onto the kingpin and is secured with the included key, so fitting takes seconds — which is deliberate, because a slow lock stops being used on a drop-and-hook operation.
Can the Kingpin Lock be used on an RV?
Yes, on a fifth wheel RV with a standard 2 in kingpin. Equipment Lock lists trailer and RV theft together as the problem this lock addresses.
What if my trailer uses a ball or pintle hitch instead of a kingpin?
Then the Ball and Ring Hitch Lock is the product that applies — it covers ball and ring hitches, which have no kingpin for this lock to enclose.
How do I choose between Keyed Alike and Keyed Differently on the Kingpin Lock?
Keyed Alike keeps your five-digit key code on file, so every Equipment Lock you buy afterwards can be cut to the same key — one key for the whole yard. Keyed Differently keeps no code on file and each lock is unique, which is the tighter choice when you want access limited to one machine. If you already have a code, select Keyed Alike and enter it at checkout.
What does the Kingpin Lock warranty cover?
Equipment Lock covers manufacturer defects for one year from purchase. Damage from a theft attempt, user error or modification falls outside that cover. Email support@eskidsteer.com with your order number to start a claim.
How is shipping calculated on the Kingpin Lock?
Shipping is calculated at checkout. Add the Kingpin Lock to your cart, enter your delivery address, and the shipping charge is shown before you complete the order.
