    Great product

    I ordered these because my stock lug nuts weren't compatible with the wheels I bought. I was very impressed with the quality of the chrome finish and the fit and function was exactly as described, not to mention that the price is right! They also double as locking lug nuts because you need the special 6 spline socket to remove them.

    Just What I needed

    Ive been needing a new set of lug nuts for about 6 weeks now and every time I needed to order these they were out of stock so I jumped on them as soon as they came available. The shipping was fast as always from AM. The lug nuts and key are a needed security for my after marked rims. Thanks AM!!!!

    Socket/key split but AM was excellent as always

    I can't speak to whether these splined lug nuts will corrode or not as I just had them installed. However, while pulling the torque wrench on the 3rd wheel, the socket split down the side. I called American Muscle and spoke to Ryan. Ryan was super friendly and is shipping me a new key/socket or whatever you want to call it. The tire shop lent me a Gorilla 1921SD socket that is a perfect fit in case I have a flat until the new AM key arrives. The Gorilla socket has a black oxide finish that looks like it is maybe made like an impact socket whereas the AM socket is chrome plated. I haven't read in feedback about this happening very often so I doubt it's of much concern. The main thing is, AM was quick to fix it and super friendly. They converted a minor failure into an A+ experience. Thank you, Ryan! Micke

    This product replaced the old one.

    I was looking for a socket to fit my old lug nuts and found it was discontinued. The new socket actually fit my old lug nuts. My lucky day!

    Added Security

    I bought these to go with my new wheels. I wanted the continued security of my wheel locks but also wanted uniformity, these fit the bill! They are also smaller in diameter so it's easier to keep the wheels clean and I don't have to worry about the lug wrench scarring my wheels.

    Nice part

    The lug nuts are great and I like the extra security with the specific wrench. They turned out to be smaller than OEM since I have the Ford optional 18" wheels, however.

    Highly Recommended

    These lugs are an absolute MUST HAVE for EVERY SINGLE SET OF NEW WHEELS YOU BUY. The 6 spline lugs and the tool to install them are much thinner than the factory lugs and sockets to install them, which means you will NEVER hack the insides of your lug holes when changing wheels or removing them for cleaning!! Best investment EVER!!

    Quality hardware, but with a frustrating flaw.

    While I was impressed with the quality of the lug nuts, the adapter I received will not fit the S197 stock lug wrench. Because the adapter is designed to fit both 3/4" and 13/16" wrenches, the stock lug wrench is far too shallow to engage the 13/16" casting on the adapter. An easily correctable oversight, if this kit was marketed separately to the S197 with a 13/16" adapter.

    They look great with my gunmetal Forgestar rims. And no worries about missing wheels when returning to car while visiting my favorite sketchy area of town!
