Gorilla Automotive 71637NBC Original Gorilla Lock System Acorn Bulge Wheel Locks 12x1.50 Black 27-Piece Set

The Gorilla Automotive 71637NBC Original Gorilla Lock System is a comprehensive wheel security solution engineered for 5-lug vehicles. This 27-piece set replaces every standard lug nut on all five wheels with a uniquely keyed locking lug nut, turning your entire wheel fastening system into a theft deterrent — not just one lock per wheel.

Key Features:

• 27-Piece Complete System: Includes 27 acorn bulge wheel locks and one matching lock key — enough to secure all lug positions across a 5-lug vehicle
• Thread Size: M12 x 1.50 thread pitch for a precise, factory-correct fit
• Hex Size: 3/4" (19mm) hex drive for easy installation and removal with standard tools and the included key
• Acorn Bulge Seat: Tapered acorn/conical seat design engineered specifically for original equipment factory aluminum wheels
• Black Chrome Finish: Heat-treated black chrome finish enhances corrosion resistance and provides a sleek, aggressive appearance that complements most wheel styles
• Unique External Security Pattern: Each lock features Gorilla's proprietary external security pattern, making removal virtually impossible without the matching key
• Heat-Treated Construction: Case-hardened steel construction improves overall durability and long-term finish retention
• Wheel Lock Key Included: One lock key is included in the set for installation and authorized removal

Important Note: This wheel lock system is designed for use with original equipment (OE) factory aluminum wheels. Compatibility with aftermarket wheels or factory steel wheels is not guaranteed — verify seat type before installation.
