Frequently Asked Questions
Will these work with my factory wheels?
Extended shank nuts are designed primarily for deeper-offset aftermarket wheels and spacer applications. Test-fit before installing on stock wheels to ensure proper seating and clearance.
Do I need a special socket to install these?
Use a standard M12 lug nut socket. The grooved shank does not require modified tooling — hand-tighten and torque to your vehicle's specification using a torque wrench.
Can aluminum lug nuts handle daily driving and track use?
Aluminum is lighter but softer than steel. Monitor threads regularly for wear and inspect seating after 100 miles. Re-torque once before normal use if this is your first install.
