Frequently Asked Questions
Do these work with my wheel studs?
These are M12x1.5 thread. Confirm your vehicle's lug specification before ordering — wrong thread pitch won't seat correctly and won't hold. Check your owner's manual or existing lug nuts if you're unsure.
What's the adapter for?
The adapter lets you adjust fitment across different wheel hub configurations. How you use it depends on your specific wheel and hub setup — test-fit before final installation.
Can I use these as-is, or do they need preparation?
They ship ready to install. Hand-wash before use to remove any shipping residue, then thread them onto your studs hand-tight first to verify alignment before fully tightening with a wrench.
