MIKKUPPA M14x1.5 spline wheel lug nuts are a 32-piece black set described for selected Chevy, GMC, Ford and Ram applications. The listing specifies closed-end nuts and includes a spline socket key, but fit depends on thread, seat shape, wheel clearance and vehicle configuration.

What to know before buying

Listing details to confirm

The listing contains inconsistencies that need confirmation: it calls the finish Zinc in one detail and Painted elsewhere, gives dimensions of 0.91 inches and 0.9 inches, and describes a 3/4-inch hex plus a 7-spline key with 3/4-inch and 7/8-inch hex sizing. Its compatibility claims span multiple Chevy, GMC, Ford and Ram models, while a separate warranty field mentions only Chevy Silverado 1500, 2500 and 3500 HD. Verify thread, seat shape, lug count, wheel clearance and the selected vehicle before ordering. It also cautions that impact wrenches may damage the coating and that some wheel-cap clips may not match the nut shape.

Who is it for?

A good fit for

Drivers checking replacement nuts for listed M14 x 1.5 Chevy, GMC, Ford or Ram applications who can verify the exact seat and wheel fit.
Buyers wanting a black, closed-end style with a spline socket key and a 32-piece quantity.

Less suited to

Anyone who cannot confirm the wheel's required seat type, thread and clearance against the listed specifications.
Buyers who need paint-coating durability or long-term loosening performance established by independent testing.

Customer feedback includes positive reports about appearance, quality, value and functionality, with some noting easy installation and a snug-fitting key. However, the supplied feedback also raises concerns about paint chipping and breakage, and reports mixed installation experiences, including nuts becoming loose over time. For buyers, those reports make coating durability and correct installation worth considering. They do not establish how the set will perform on a particular vehicle.

Frequently asked questions

What thread size does this lug nut set use?

The listing specifies M14 x 1.5 threads. Confirm that this matches the vehicle and wheel hardware.

What is included in the set?

The product highlight describes 32 black closed-end nuts with a socket key. The specification says the key uses a 7-spline design and lists 3/4-inch and 7/8-inch hex sizing, so confirm the selected listing's kit details.

Will these fit my vehicle?

The listing names selected Chevy, GMC, Ford and Ram models, but model year alone is not enough to establish fit. Verify thread, seat shape, lug count and wheel clearance against your specific setup.

Can I use an impact wrench to install them?

The listing warns that an electric impact wrench may damage the surface coating and recommends a hand wrench. It also gives torque figures for several thread sizes, so follow vehicle-specific requirements.
