SLONG AIRSOFT | Metal Gear Spacer Shim Set | 0.10mm & 0.15mm (30-Pack)

When building high-speed or high-torque AEG setups, standard-sized shims often don't cut it. To achieve a flawless cycle, you need the micro-precision offered by the Slong Airsoft Metal Gear Spacer Shim Set. This 30-pack of ultra-thin washers is the ultimate tool for erasing the tiniest mechanical tolerances inside your gearbox shell.

Micro-Precision for High-End Tuning While thicker shims are great for shifting a gear away from the gearbox wall, these micro-shims (0.10mm and 0.15mm) are designed for the critical final stage of shimming. They allow you to close up the fractional, sub-millimeter gaps that cause gears to tilt under load. Removing this final bit of play ensures that the teeth mesh perfectly flat against each other. This results in maximum power transfer from your motor, a significantly quieter "snappy" acoustic signature, and an incredibly smooth cyclic rate.

Durable, Deflection-Resistant Build Slong Airsoft has manufactured these shims from high-tensile, stamped metal alloy. Unlike cheap washers that can warp, compress, or shred under the extreme rotational stress of a high-voltage LiPo setup, these shims maintain their structural thickness over millions of cycles. With 30 pieces total in the pack, you will have an ample supply on hand to outfit multiple customer builds or personal overhaul projects.

Key Technical Features:

• Ultra-Thin Micro Sizes: 0.10mm and 0.15mm thicknesses provide the precise control needed for master-level shimming.

• Bulk 30-Piece Pack: Generous quantity ensures you have plenty of matching spacers for multiple gear axles.

• High-Tensile Metal Alloy: Stamped to resist crushing, bending, or wearing thin under heavy structural loads.

• Maximizes Internal Longevity: Eliminates gear tilt to protect your gear teeth, piston rack, and motor pinion from premature stripping.

• Universal Internal Match: Perfectly sized to slide onto standard AEG gear axles across Version 2, 3, and alternative gearbox variants.

Field & Tech Recommendations Micro-shimming requires an incremental approach. Always tighten your gearbox shell screws completely when checking gear play, as loose shells create false tolerances. For a professional-tier build, shim your bevel gear directly to the motor pinion first, then utilize these Slong micro-shims to align the spur and sector gears accordingly. Ensure a light coating of premium synthetic grease is applied to the shims during final assembly.
