M12 x 1.25 L40 Style Extended Lug Nuts with Locks - Aluminum
Lightweight aluminum lug nuts with integrated lock design in M12 x 1.25 L40 fitment. Extended length accommodates thicker wheel spacers and aftermarket wheels without compromising thread engagement. Aluminum construction reduces unsprung weight while maintaining secure clamping force.
Do these lock nuts need to be torqued to a specific value?
Refer to your vehicle's service manual for the correct torque specification for M12 fasteners. The lock design engages during normal tightening — no special procedure required.
Will these work with my aftermarket wheels and spacers?
L40 length is designed for extended applications like thick spacers and deep-dish wheels. Measure your hub surface to the wheel mounting face to confirm clearance before installation.
Can I use these as a direct replacement for my stock lug nuts?
Thread size and pitch are M12 x 1.25 — verify your vehicle uses this specification before purchase. If your factory nuts are a different size, these will not fit.
