Will these fit my wheels with a spacer kit?

Extended lug nuts are designed for exactly this scenario — wheels pushed out via spacers, wide-body kits, or deep offset rims. Stock nuts won't reach the stud far enough. Verify your thread size matches M12 x 1.25 before ordering.

Do the four locking nuts work the same way as the standard ones?

Yes. The locking nuts use the same M12 x 1.25 thread and extended length as the standard nuts. Mix and match them around your wheel for theft resistance — common practice is one locking nut per wheel, though you can use multiple.

Can I reuse these if I swap wheels later?

Absolutely. As long as your next wheels also run M12 x 1.25 studs and need the extended reach, these nuts stay in rotation. They're not vehicle-specific, just thread-specific.
