Ultimate BOOST Gear Set /16.5:1

Designed to offer enhanced performance to any custom airsoft build, the Ultimate BOOST range of gears provide smooth and reliable power transfer in your AEG. Each gear set is precision engineered to safely deliver the precise rate of fire you demand from your airsoft gun.

Our latest addition to the Ultimate upgrade parts series consists of a selection of airsoft gears specially engineered for peak performance and using state-of-the-art technology for ULTIMATE durability. What’s more, our new range of gear sets offers you more gear ratio options than ever before, allowing greater freedom for custom gearbox builds.

Our new BOOST Gear set range is available in 13.5:1, 16.5:1 and 19.5:1 gear ratios. So, whether you’re building the ULTIMATE DMR or a specialist high-speed CQB AEG, we’ve got the perfect solution at a competitive price point.

Every metal injection-moulded gear set is differentially heat-treated to provide the optimum hardness for each point of contact and crafted with precision engineering. This results in resilient and perfectly formed components that are as smooth as they are tough.

Now with Ultimate BOOST gear sets, channelling power from an ASG motor through to our Ultimate mil-spec springs, a second-to-none power transition can be achieved in any custom airsoft build.
