Add a locking wheel nut to each corner of your car to replace one of your MMX nuts for extra security.

Each kit comes with a removal tool with a security pattern that precisely matches the head pattern of each of the X4 locking bolts in your kit.

Install really couldn’t be easier! Simply remove one of your MMX nuts from each wheel, and replace it with the locking version.

Each aluminium locking nut is finished in exactly the same gloss black anodised as your MMX nuts to match in perfectly.
