ELEMENT Gear Shim Set | 6mm & 7mm Outer Diameter | 0.4mm & 0.6mm Thickness Washers

When it comes to building a reliable, high-performance Airsoft Electric Gun (AEG), proper gearbox shimming is arguably the most critical step. The ELEMENT Gear Shim Set provides the exact precision hardware required to perfectly align your spur, bevel, and sector gears, ensuring maximum mechanical efficiency.

Achieve Perfect Mechanical Efficiency Out of the box, many factory airsoft gearboxes have slight tolerances that allow the gears to shift slightly on their axles. This lateral movement causes inefficient power transfer from the motor, excessive noise, and uneven wear that can lead to stripped gears. By placing these precision-stamped ELEMENT washers onto the gear axles, you can systematically remove that extra play. This ensures the gears mesh perfectly with maximum surface contact, resulting in a significantly quieter gearbox cycle and a snappier trigger response.

Versatile Sizing for Varied Builds This comprehensive pack features a smart selection of sizes to accommodate standard AEG gear axels. With both 6mm and 7mm outer diameter options, you have the flexibility to shim across a wide range of standard bushings and bearings. The inclusion of 0.4mm and 0.6mm thickness washers allows you to make substantial spacing adjustments quickly without stack-loading a dozen micro-thin shims, saving you valuable time on the tech bench.

Key Technical Features:

• Dual Outer Diameters: Includes 6mm and 7mm washers to properly clear different sizes of gearbox bushings and bearings.

• Thicker Spacing Options: 0.4mm and 0.6mm thicknesses provide a solid foundation for major gear spacing adjustments.

• Premium Stamped Metal: Built from rigid metal alloys that resist crushing or warping under the high rotational pressure of upgraded motors.

• Reduces Gearbox Wear: Minimizes friction and prevents uneven stress on gear teeth, extending the lifespan of your internal components.

• Essential Tech Component: A must-have item for routine gearbox shimming, sector clip installations, or complete internal overhauls.

Field & Tech Recommendations Shimming a gearbox requires patience and precision. Always test your gear rotation with the gearbox shell screwed fully together to ensure the gears spin freely without binding. For optimal performance, we recommend cleaning away old factory grease before shimming and applying a high-quality lithium or Teflon-based gear grease once your spacing is perfectly set.
