Will these fit my current wheels without modification?

These are M12 x 1.25 metric fasteners. Confirm your vehicle uses this thread size before ordering — cross-reference your owner's manual or existing lug nut specs. If you run a different thread pitch, these won't thread properly.

Do I need to torque these to a specific spec?

Always refer to your vehicle's service manual for the correct torque specification. Over- or under-torquing can cause wheel damage or loss of security. Aluminum lug nuts require the same attention as steel ones.

Can I use these with wheel spacers?

The extended length is designed to work with spacers and deeper-dish wheels. Verify the stud length still leaves enough thread engagement — you want at least three full threads gripping the nut for safety.
