Will these fit my deep-dish wheels?

44mm length covers most deep-center and barrel-style wheels. If your wheel bore is extremely deep or you're running spacers, test-fit before final install. Lug nut exposure matters for safety and appearance.

Do I need to do anything to the aluminum before installation?

They ship ready to install. Wipe clean before use. If you want a high-polish look, mild soap and water or dedicated aluminum cleaner works. No primer or coating needed.

What's the torque spec for these?

Refer to your vehicle's service manual for the correct torque value — it's based on your specific wheel and hub, not the lug nut material. Over-torquing aluminum nuts can strip them, so follow factory specs exactly.
