Gorilla Automotive Wheel Lug Nut Washer

Gorilla Automotive Wheel Lug Nut Washers: The Right Companion for Classic and Specialty Wheels

When it comes to properly securing mag-style and specialty wheels, the lug nut washer is one of the most overlooked yet critical components in the assembly. Gorilla Automotive — a name synonymous with wheel fastener quality since 1976 — brings the same precision and durability that defines their lug nut lineup to their dedicated line of wheel lug nut washers.

Gorilla Automotive has been at the forefront of wheel fastener innovation for decades, and their washer products reflect that deep engineering expertise. As the brand puts it, these washers are designed to be "a perfect fit for your classic wheels with mag lug nuts" — a nod to their specific purpose of distributing clamping load evenly across the wheel surface to protect both the fastener seat and the wheel itself.

Purpose-Built Washer Varieties

Gorilla's lug nut washer lineup is purpose-built rather than one-size-fits-all. The range includes several distinct varieties engineered to match specific lug nut styles and wheel applications:

• Standard Mag Washers (e.g., 79900): Sized to pair with traditional mag-style lug nuts, these washers provide the broad seating surface that open-face mag wheels require for a flush, secure fit.
• Short Shank Washers (e.g., 79903): Featuring a 0.695" inner diameter and approximately 1.224" outer diameter at 0.12" thickness, these are matched for use with Gorilla short shank lug nuts on classic and custom wheels.
• Keystone Offset Washers (e.g., 79905B): With an oval profile (approximately 1.312" x 1.065"), these address offset lug seat geometries common on vintage and specialty aftermarket wheels.
• Cragar Center & Offset Washers (e.g., 79912, 79913): Chrome-finished steel washers with a 0.695" inner diameter and 1.25" outer diameter at 0.157" thickness, purpose-designed for Cragar-style center and offset lug applications.

Materials and Finish

Gorilla lug nut washers are constructed from steel and are available in two primary finish options depending on the application: a protective zinc oxide (zinc plated) finish for corrosion resistance in everyday use, or a polished chrome finish for custom and show-quality wheel builds. Some kits — like the Standard Mag Closed End lug nut sets — bundle matching washers directly with the lug nuts, ensuring finish consistency and a guaranteed dimensional fit right out of the box.

Why Choose Gorilla for Washers?

Because Gorilla designs their washers in tandem with their lug nut product lines, there is no guesswork about compatibility. The washers are engineered to work as a system — matched inner diameters, corresponding seating geometry, and complementary finishes — so that the torque applied to the lug nut transfers uniformly to the wheel. Gorilla also backs their products with a one-year warranty against defects in materials or workmanship, underscoring their confidence in long-term quality.

For enthusiasts building out a classic restomod, custom street machine, or any vehicle running mag-style wheels, Gorilla's lug nut washers are a small but essential detail that keeps the entire wheel assembly safe and looking sharp.
