Shim sets

Shim Sets for AEGs - for quiet operation, perfect alignment and maximum efficiency

Shim Sets form the basis for a smoothly running and quiet AEG gearbox. The right shims ensure optimal alignment of gears, less resistance and a longer service life for your internal parts. In this category, you will find high-quality shim sets in precise thicknesses, made for players who want their gearbox to function efficiently, quietly and durably. Whether you are optimising a standard build, building a high-torque system or carrying out a DSG project, shims make all the difference.

Why choose shim sets?

Shims determine the perfect distance between the gears in your gearbox, allowing them to run more smoothly and quietly. By reducing wear and preventing unwanted friction, you extend the life of your gears and motor. With precise thicknesses, you can fine-tune the bevel, spur and sector gears, which directly affects noise, efficiency and performance. A well-shimmed gearbox is quieter, stronger and more reliable.

What can you find in this category?

• Complete shim sets in thicknesses from 0.1 mm to 0.3 mm
• Compatible sets for V2, V3 and other popular AEG gearbox types
• Precise shims made of hardened steel for maximum durability
• Sets that are ideal for DSG builds, high-speed and high-torque configurations
• Models from brands such as Element, Epes, G&G, Guarder and more

Who is it suitable for?

Shim sets are ideal for airsoft technicians who want to refine their gearbox, players who want a quiet or efficient replica, and tuners who want to get the most out of their internal upgrades. Also suitable for anyone who wants to reduce wear and tear and achieve better performance.

Frequently asked questions

What exactly does a shim set do?

A shim set ensures precise alignment of gears, resulting in smoother operation, less wear and less noise.

Are all shim sets universally applicable?

Most sets fit standard gearbox types such as V2 and V3, but check that the thicknesses match your build.

When should I replace my shims?

If your replica sounds noisy, shows friction or has uneven gear wear, replacement is necessary.

Can I shim myself or does a technician have to do it?

Shimming requires precision work down to hundredths of a millimetre. With experience, you can do this yourself, but many players have a technician do it.

Buying guide

• Check which gearbox type you are using
• Combine different thicknesses for optimal alignment
• Use hardened steel shims for durability
• Match your shims to the desired build, such as high-speed or high-torque
• Check gear play carefully during assembly

Top tip: Use high-quality gear grease and combine your shim set with a matching gear set for quiet, efficient and long-lasting operation.

For a complete internal upgrade, AEG Gear Sets, Motors & Pinion Gears, Pistons & Piston Heads, Cylinder & Cylinder Heads, Nozzles, Springs & Spring Guides and Hop-Up parts are a perfect fit for this category.
