Orion Motor Tech Locking Hitch Pin Set — 2-Pack 5/8" Keyed-Alike, Hardened Steel & Vibration-Damping

Orion Motor Tech's 2-pack locking hitch pins are keyed-alike, 5/8" hardened-steel pins designed to secure 2", 2.5" and 3" trailer receivers quickly and quietly.

Whether you're towing a trailer, storing a hitch-mounted accessory, or swapping ball mounts, these locking hitch pins give a simple, reliable way to lock your receiver. The two included locks use the same key for convenience, and the construction combines a hardened-steel core with vibration-damping features to cut noise and resist tampering. Installation and removal are fast — slide the pin through, twist the protective cap, and you're locked down.

How do these hitch pins prevent theft and tampering?

The locks use a hardened 40Cr steel pin and a drop-proof lock design that resists cutting and prying. Multiple locking points and a drilled hole for the R-clip create redundancy, making casual theft attempts much harder. The keyed-alike pair keeps things simple when you need to lock two points at once.

• Hardened 40Cr steel pin for high shear strength
• Drop-proof locking core reduces vulnerability to forced entry
• Drilled hole plus R-clip and internal locking mechanism for triple security
• Two locks keyed alike for single-key convenience

Will this fit my receiver and how stable is it while towing?

The pin measures 5/8" in diameter with a 7.8" overall length and a 4.2" effective length, engineered to suit 2", 2.5" and 3" receivers and most adjustable ball mounts. Its fit minimizes lateral movement so the hitch doesn't rattle during travel. Twelve O-rings help absorb vibration and significantly reduce noise for a quieter ride.

• 5/8" diameter fits standard receiver hitch holes
• 7.8" total length and 4.2" effective length for common receiver depths
• 12 O-rings dampen vibration and cut road noise
• Compatible with adjustable ball mounts and many accessories

How quickly can I install or remove the locking pin?

Installation is tool-free and takes seconds: slide the pin through the receiver and accessory, then twist the aluminum cap to engage the lock. Unlocking is equally fast — insert the key and twist to release. The simple action makes swapping mounts or removing the hitch straightforward even in the field.

• Tool-free slide-and-twist installation
• Quick key rotation for fast removal
• Protective aluminum cap shields the lock from dirt and weather
• Keyed-alike design saves time when locking multiple points

What materials and design features improve longevity and ride comfort?

The pin's 40Cr steel construction resists breakage while O-rings and a snug fit lower noise and wear between components. The aluminum cap is corrosion-resistant, helping the lock perform through seasons. Thoughtful engineering like drilled holes for secure clips prolongs both security and service life.

• 40Cr steel pin reduces risk of bending or breakage
• Aluminum cap resists corrosion and environmental wear
• Multiple O-rings reduce friction and rattle over time
• Drilled hole and R-clip offer additional mechanical backup

This Orion Motor Tech 2-pack locking hitch pin set is ideal for truck and SUV owners who tow, store trailers, or use hitch-mounted gear and want a fast, reliable way to secure their setup. It's especially useful if you need to lock both your receiver and an adjustable ball mount without juggling multiple keys. The set balances theft resistance, quiet operation, and quick usability for everyday towing and storage needs.
