Shims are one of the most essential parts of any gearbox, ensuring proper spacing between gears to protect against wear. This high quality, high-precision JBU shim set is a must have for any serious airsoft technician, allowing you to get the perfect angle of engagement for each gear in any type of gearbox. Properly shimming a gearbox can result in a longer life of the AEG's gearbox, and improved consistency and performance. Re-shimming is recommended to be done only by experienced Airsoft technicians.

Shim Set Includes: 6 x 0.20mm shims, 6 x 0.35mm shims, 6 x 0.55mm shims (18 total)

Disclaimer: Any and all airsoft upgrade parts purchased from Airsoft Megastore will be used/installed at owner's discretion. Actual performance results depend on quality of installation, airsoft AEG barrel length, tightness of the air nozzle seal, and other possible performance-affecting factors. We are not responsible for any damage that may occur with improper installation. For best results, please do all upgrades at a certified professional airsoft technician/shop.

XTREME Returns

As a small business, we face a choice: we can either raise all of our prices to cover the cost of returns, or we can keep our prices low and offer an optional Return Guarantee. We chose the second option because it's fairer to you. That $5 goes directly toward the logistics of a pre-paid return, meaning you get a "no-questions-asked" experience without us having to inflate the cost of every item in our shop. It keeps us independent and keeps your wallet happy. When you shop with us, your order isn’t just a number—it’s handled by a small team that cares about the gear we sell. Because we don't have the massive overhead of a giant company, we use this $5 guarantee to bridge the gap. It provides you with a pre-paid, priority return path, ensuring that if you need to send something back, we can process it immediately and get your refund or exchange moving. Thank you so much for understanding.
