Orion Motor Tech locking hitch pin set 2-pack — 5/8" pins for 2", 2.5" & 3" receivers, keyed alike, anti-rattle

Orion Motor Tech's 2-pack locking hitch pins are keyed alike, heavy-duty 5/8" pins designed to secure 2", 2.5" and 3" trailer receivers with a noise-damping, anti-theft design.

Built to keep trailers, bike racks, and adjustable ball mounts locked in place, this pair of hitch pins combines a hardened 40Cr steel pin with an aluminum locking cap, multiple O-rings to eliminate rattle, and a drilled hole plus R-clip for layered security. Each set arrives keyed alike so both locks open with the same two included keys, letting you protect two receivers or a receiver and a ball mount without juggling extra keys.

How does this hitch pin prevent theft and tampering?

The OMT locking hitch pin uses a hardened steel core and a drop-proof locking cap that resists pry attempts and cutting. The drilled pin hole accepts an R-clip for secondary mechanical retention while the lock housing covers the keyway to reduce direct access.

• 40Cr hardened steel pin resists bending and cutting
• Drop-proof aluminum cap protects the lock cylinder
• Drilled hole with R-clip adds a mechanical backup
• Keyed alike set simplifies key management across two locks

Will these pins fit my receiver and how secure is the fit?

Designed for universal fit across common receiver sizes, the pins have a 5/8" diameter and a 7.8" overall length, with 4.2" effective length to clear the receiver wall and secure most accessories. The snug diameter and multiple O-rings minimize movement and keep the hitch assembly stable while towing.

• Fits 2", 2.5", and 3" receivers
• 5/8" pin diameter provides a precise, strong fit
• 4.2" effective length secures accessories with minimal play
• 12 O-rings reduce vibration and prevent rattle

How easy is installation and daily use?

Installation is fast: slide the pin through the receiver and accessory, then twist the aluminum cap to engage the lock. Removing the pin is just as quick—insert the key, turn, and pull—so routine hitching and unhitching remains convenient.

• Push-and-twist locking cap for one-handed use
• Two keys included per set, keyed alike
• R-clip and drilled hole for additional manual locking
• Low-profile design keeps access simple and quick

How durable is the pin for frequent towing and weather exposure?

The core construction and corrosion-resistant components are chosen for repeated use in harsh conditions. The steel pin resists breakage while the aluminum cap and O-rings maintain performance in rain, road salt, and repeated installation cycles.

• 40Cr steel core for impact and shear resistance
• Aluminum cap balances strength and lightweight handling
• Multiple O-rings protect finish and cut down on moisture ingress
• Robust mechanical design tolerates frequent use and road conditions

Who is this for? The Orion Motor Tech 2-pack locking hitch pin set is intended for truck and SUV owners, frequent haulers, and anyone who uses trailer accessories like bike racks or cargo carriers and wants a simple, reliable anti-theft solution. It’s also a good choice for fleet managers who need identical keys across multiple vehicles, or for owners who prefer a quiet tow thanks to vibration-damping O-rings. If you want a durable, easy-to-use, keyed-alike lock designed to fit multiple receiver sizes and keep accessories secure on the road or in storage, this set provides a practical, low-friction option.
