Counteracts Wheel Centering Sleeve work in conjunction with your OEM two-piece flange nuts. Designed to take up the gap between the stud and the wheel opening, re-aligning the wheel to the TRUE CENTER of the Hub Bearing.

Tested and validated to not interfere with torque or clamping force ensuring proper wheel security. Tested to withstand the heat of 450-degrees Fahrenheit, well beyond the melting point of the wheel itself. Available in 20mm and 22mm. Comes in 6, 100 & 1000 quantities!
