Fitment and specs

• Spline drive tuner lug key, 6 spline pattern
• Fits spline tuner lug nuts with a 6 point head
• Guaranteed to fit the spline tuner lug nuts we sell; fit with other brands is not guaranteed
• Not for duplex lug nuts

Seat the key fully into the lug nut opening before applying any force, and keep it square to the nut so the splines engage evenly. A half-seated key is the quickest way to round out a spline nut. When tightening lug nuts through the key, torque to the spec in our torque reference chart and re-torque after 50 to 100 miles.

Common questions

How do I confirm I need the 6 spline version?
Look straight down at the head of one of your spline lug nuts and count the rounded grooves around the opening. Six grooves means this key. If you count seven, you need the 7 spline key instead.

Will it open spline lug nuts I bought somewhere else?
We only guarantee fit with the spline tuner lug nuts sold here, since spline profiles vary between manufacturers. It also does not fit duplex lug nuts, which take a different key entirely.
