Siegetek Concepts – Uncompromising engineering for your gearbox
When you reach the point where stock gears and ordinary upgrades are no longer enough, Siegetek Concepts comes into the picture. Siegetek makes gears that are not just strong – they are practically indestructible. They are designed and manufactured in the USA to precision tolerances normally found only in the aerospace industry. We recommend Siegetek if you are building a rifle with an extreme rate of fire or a very powerful spring, and never want to worry about stripped teeth again.
Cyclone and Revolution: gears for the wildest builds
Siegetek is especially known for its gear configurations, which push the limits of what an AEG can do:
Cyclone Dual Sector Gear (DSG): The original DSG system, which lets your piston cycle twice for every rotation of the sector gear. It is the key to the fast 50+ RPS builds you see on the field.
Revolution Series: Their classic gear sets, available in different ratios (e.g. 10.44:1 or 14.09:1). They are made to handle even the most powerful motors and Nuprol LiPo batteries without giving way.
Hardened chromoly steel: Every gear is CNC-machined from a single piece of steel and then hardened, which makes them resistant to wear for years.
Technical edge
Why is Siegetek worth the price?
Precise geometry: The tooth profile is optimised to minimise friction and noise, giving your gearbox a more efficient and crisper cycle.
Reinforced axles: The axles are designed to withstand the torsion that occurs in high-torque setups, protecting your bearings and your Retro Arms gearbox shell.
An investment for life: In most cases, a Siegetek gear set will outlive the rifle itself. It is the last upgrade you will ever need to make to your drivetrain.
Looking after your Siegetek gearbox
Working with components of this calibre takes technical skill:
Precise shimming: Because Siegetek gears are made from very hard steel, perfect shimming is essential. Mistakes here can lead to unnecessary wear on other, softer parts.
Quality lubrication: Only use the best grease on your gears to keep friction low. You will find everything you need in our airsoft cleaning and maintenance collection.
Match with top parts: A Siegetek setup should always be paired with a steel-toothed piston from SHS and quality BBs from Hank Tactical.
