Will these fit my current wheels without modification?

The M12X1.25 thread pattern is common on many vehicles, but confirm your hub's thread specification before purchase. Test-fit one lug nut on a wheel to verify compatibility — forcing an incorrect size can damage both the nut and hub.

Do I need to prep or paint these before installing?

They arrive in black anodized finish and are ready to install. If you prefer a different look, sand lightly with fine-grit paper before applying your own coating, but the factory finish is durable as-is.

What torque spec should I use when installing?

Refer to your vehicle's service manual for the correct torque value — it varies by manufacturer and hub design. Over-tightening aluminum nuts can strip threads; under-tightening creates safety risk. Use a calibrated torque wrench every time.
