Frequently Asked Questions
Do these work with my factory wheels or do I need aftermarket wheels?
M12 x 1.25 is a common standard thread pitch, so these fit most bolt patterns — factory or aftermarket. Verify your lug nut thread pitch before ordering to confirm compatibility.
Are the lock rings keyed, or do they work on any lug nut?
Each lock ring requires a unique key to remove. You get one key per set. Keep it safe — losing the key means the lock rings stay on until they're drilled out.
Will these extend beyond my wheel face, or do they sit flush?
L40 length is designed for spacers and deeper offsets. Test-fit one lug nut on your wheel before installing all twenty — depending on your wheel design, they may protrude slightly beyond the face.
