Gorilla 9/16 in Black Duplex Acorn Wheel Lock Set - Secure Wheels

In this review the Gorilla 9/16 in Black Duplex Acorn Wheel Lock set earns a recommendation for drivers who want a straightforward, durable way to protect aftermarket wheels. The bottom line is simple: these locks combine hardened steel construction and a unique external security pattern to make theft far less likely while still being easy to install. The set ships with four locks and a dual hex key that fits common lug tools, so it is a practical, no-nonsense upgrade for anyone fitting new rims or replacing worn lug locks.

Key Features

• Hardened steel construction: The locks are made from hardened steel to resist stripping and provide long term durability under road conditions.
• Triple chrome plated finish: Triple chrome plating gives a clean, corrosion resistant surface that maintains appearance on black lug sets and chrome accents.
• Unique external security pattern: The external pattern lets the included key engage reliably while deterring casual thieves who lack the matching key.
• Chrome vanadium dual hex key: The included key has 13/16 in and 7/8 in hex sizes so it works with common wrench sizes and makes installation quick.
• Complete kit: The package includes four locks, one key and a registration sticker so owners can document the lock pattern for future reference.

Who It's For

This wheel lock set is aimed at motorists who own aftermarket wheels or higher value rims and want a clear step up in security without complicated installation. It is a good match for owners of SUVs, trucks, and passenger cars fitting larger wheels where standard lug nuts would be an easy target for theft.

Drivers who need keyed systems with exact OEM fitment charts should verify thread size and seat type before buying, and those who prefer electronic wheel security systems or wheel sensors should look elsewhere. For most people upgrading to stronger, visible wheel locks the Gorilla set is a practical, cost effective choice.
