A must-have for every pit box, the Exalt Machined Aluminum Rotor Shims are essential for proper motor tuning and chassis setup. These high-precision shims are designed to help perfectly center your rotor within the magnetic field—ensuring optimal performance, efficiency, and consistency during rebuilds.
