Show original supplier description
The Gorilla 91188 is a set of acorn-style bulge lug nuts crafted to ensure your vehicle remains in excellent working order. These lug nuts feature a durable chrome finish, providing superior corrosion resistance and a stylish appearance that complements both stock and aftermarket wheels. Each lug nut is precisely manufactured with a 1/2"-20 thread pitch and a 13/16" hex size, ensuring a secure fit. This product is offered as a set of 100, providing ample supply for multiple wheels or vehicles. Gorilla has been a leader in the auto accessories industry for over 35 years, renowned for the quality, functionality, and innovation of their products. The 91188 lug nuts exemplify this commitment to excellence, designed for pinpoint accuracy and long-lasting performance. The acorn-style bulge design includes a tapered base, which allows the lug nut to properly seat against the wheel, ensuring stability and proper load distribution. These lug nuts are intended for vehicles with stock-length wheel studs and are a recommended upgrade when installing American Racing Wheels or other aluminum aftermarket wheels, particularly on early model Mustangs. While these lug nuts are described as universal, specific fitment details highlight compatibility with a wide range of vehicles, including all 1965-1973 and 1979-2014 Ford Mustangs. For these Mustang models, four sets of this product would be required to equip the entire vehicle. It is important to confirm that the 1/2"-20 thread pitch and 13/16" hex size are appropriate for your specific wheel and vehicle application.
