RETRUE Trailer Hitch Lock Set — Keyed Alike 3-Piece Kit, Black, Adjustable Coupler & Receiver Pins

RETRUE Keyed Alike Trailer Hitch Lock Set is a three-piece anti-theft kit that secures your trailer coupler, hitch receiver and latch‑type tongue with one matching key for fast, dependable protection.

When leaving a trailer, boat, or cargo carrier unattended, a compact, durable locking solution removes worry and speeds hitching. The RETRUE kit combines an adjustable coupler lock, two receiver pins for different pin diameters and a tongue lock pin that fits latch‑style couplers, all keyed alike so you only carry one keyset. Built from corrosion-resistant aluminum and high-strength A36 steel and designed with upgraded cylinders and thicker keys, it balances corrosion protection with cut-and-shear resistance for everyday use.

How does this kit fit different trailer couplers and receivers?

The RETRUE set has adjustable and multiple-diameter components to match common trailer hardware. The coupler lock offers 11 locking positions to accommodate 1-7/8", 2" and 2-5/16" ball couplers, while the receiver pins come in two sizes to fit common hitch receivers. The tongue lock pin is slim enough for latch-style couplers with small spans.

• Coupler lock: 11 adjustable positions for 1-7/8", 2", 2-5/16" balls
• Receiver pins: 5/8" pin (effective 2.8"), 1/2" pin (effective 2.2")
• Tongue lock pin: 1/4" diameter fits latch couplers up to 3/4" span

How secure and weatherproof is the RETRUE hitch lock set?

Security combines material strength and a reinforced cylinder to resist cutting and tampering. The body uses rustproof aluminum with A36 steel internal parts for shear and cut resistance, while upgraded lock cylinders and thicker keys make forced entry more difficult. Each piece is built to withstand outdoor conditions and routine wear.

• Aluminum exterior to resist corrosion and reduce weight
• A36 steel components for improved shear and cut resistance
• More complex cylinders and thicker keys to deter forced entry

What convenience features speed daily use?

All three locks are keyed alike and shipped with four matching keys so you can secure multiple trailers or hand a spare to a partner. The adjustable coupler lock requires only one tool-free setup across its 11 positions, and the included receiver pins cover common hitch sizes for quick swap-in protection. The compact design stores easily when not in use.

• Four identical keys for all three locks—no juggling key rings
• Tool-free adjustment for the coupler lock across 11 positions
• Compact components that tuck into console storage or a trailer toolbox
