SplineDrive Tuner Lug Nut & Lock Kit – M12x1.5 Black - McGard 65557BK

Secure your wheels in style with the McGard SplineDrive Tuner 5-Lug Install Kit (Part #65557BK). Designed for performance-focused enthusiasts and track-day racers, this complete kit includes 20 spline-drive lug nuts, 4 wheel locks, and a matching installation tool—everything you need to properly mount four wheels and tires.

Unlike ordinary lug nuts, McGard’s SplineDrive design is engineered to fit small-diameter tuner-style wheels while offering maximum gripping power, increased stud engagement, and a greater seating surface for superior strength. The closed-end design adds durability while protecting studs from dirt and corrosion.

Each piece is 30% lighter than standard socket-style lug nuts, making them ideal for drivers who care about reducing unsprung weight without compromising safety. Finished in a sleek black PVD coating, these lugs won’t chip, peel, or rust—backed by McGard’s lifetime guarantee.

Security comes standard with the included wheel locks. The computer-generated key pattern system ensures an almost infinite number of unique combinations, making your setup both stylish and theft-resistant. The single-piece wheel locks function just like a lug nut, but require the included key tool for installation and removal.

Proudly manufactured in the USA from through-hardened, restricted-chemistry steel, McGard lug nuts and locks meet or exceed OEM standards for strength and durability. Built for aluminum cone-seat wheels only, this kit is a perfect fit for Mazda Miata owners running aftermarket wheels and racers looking for peace of mind on track.

Upgrade to McGard and enjoy race-ready security, lighter weight, and long-lasting style in one convenient package.
