They offer a convenient way to order the wheel locks and the lug nuts that come with all the hardware that one needs to install the 4 road wheels or tires and one for the spare tire for the Jeep Wrangler. Mcgard in the U.S.A. is known to manufacture wheel locks and lug nuts that are known to meet and even exceed the O.E.M standards on safety and durability. At the moment McGard is known to supply original equipment for more than 30 car lines all over the world. The wheel locks come in one piece and are very easy to use but they need one special key tool for both the installation and removal. The key designs are computer generated and this allows for infinite number of designs. You are guaranteed that the nuts will nit rust, peel, or chip over their life time. They can handle harsh elements, corrosive wheel cleaners and lead foot drivers that ordinary lug nuts cannot. They are designed to take the punishment but at the same time make the wheel look great. Each lug nut and lock has been machined from steel and hardened so that it offers higher levels of security and safety. The Bulge Style Cone Seat lug nuts have been designed to have an extended seating surface so as to match the wider seating surface that is used on the aluminium wheels. They can be used with wheels that have exposed decorative lug nuts that are tapered at the bottom.
