Frequently Asked Questions
Will these work with my factory wheels?
L40 extended nuts are designed for aftermarket wheels with recessed seats. Test-fit them on your specific wheel before committing — some factory wheels require standard-height nuts. Measure the wheel's lug seat depth if unsure.
Do I need a special socket or wrench to install these?
Standard lug nut sockets and wrenches work with M12 x 1.25 nuts. Tighten to your vehicle's manufacturer torque specification — check your service manual for the exact value.
Will aluminum lug nuts corrode in winter or wet climates?
Aluminum resists rust better than steel, but salt and moisture can still cause oxidation over time. Inspect them periodically and clean off road salt if you live in harsh winter conditions.
