Muteki 32901B SR48 Locking Lug Nut Product Review

The Muteki 32901B SR48 Locking Lug nuts have become a popular choice for professional drivers in the sport compact community due to their slim profile that works well with many aftermarket style wheels.

You won’t want any drives to be weighed down by the additional weight of bulky locks. That’s why at 2 ounces, these ultra-light wheel locks are a lot lighter compared to its competitors.

If you purchase this product, you will receive four locking lug nuts that use a specific lug key for removal to secure each wheel to your vehicle. Not just this, the kit also comes with a spare key, which a lot of its competitors fail to provide consumers.

For optimal security, these wheel locks are crafted from cold-forged and heat-treated vanadium metal, which will bring ease to your purchase, knowing they are built tough.

The wheels are cold-forged into the desired shape, and then the heat-treatment strengthens the piece. The wheels are then oversized in a 60-degree cone seat for better contact on your wheels.

The cold-forge and heat-treatment is known as tempering. This process has grown in popularity because of its market reaction because of its attractive exterior, which remains rugged for much longer.

The Muteki SR48 range of wheel locks offers consumers a variety of colors to choose from, which will entertain different cars and wheels, to make them as noticeable as possible to deter any potential thieves. The colors include black, purple, chrome titanium, and neon chrome.

Some might say that color doesn’t matter, but we all have a preference, and having a choice is always great!
Although pricier than some featured on both the market and our list, you will find this locking lug nut on the market at a reasonable price without stretching your budget.

If you want racing driver star feels to your wheels, then this would be an excellent choice for you!


After checking out the Muteki 32901B SR48 Locking Lug Nut, there is definitely a theme of quality wheel locks that are crafted from Mackin Industries, Inc., and we believe these wheel locks would be an excellent addition to your vehicle.

Although these wheels are a bit expensive, there is no denying the Japanese engineered nuts look a lot better and will be a worthy long-term investment.

The steel used to craft wheel locks is the foundation of successful wheel locks for the security of your wheels. That’s why these cold-forged vanadium metal wheel locks will be rugged enough to be a one-and-only purchase.
