AEG Pistons & Piston Heads

AEG pistons and piston heads sit right in the middle of durability and compression performance inside the gearbox. They help determine how well the build holds up under repeated use, how consistently the air system functions and how much confidence the user can have in the internals once the tune becomes more demanding.

This section is built for builders replacing worn parts, improving reliability or trying to create a stronger overall gearbox foundation. These are not decorative upgrades. They are the parts that matter when the internal build has to survive real use and stay consistent over time.
