Axial's Yeti Transmission 2-Speed Hi/Lo Component Kit includes a full set (3) of heat treated hardened steel machined gears, plus an additional optional high speed gear (Hi Gear Option), full set of cartridge bearings, two different servo mounting options (micro or standard), servo saver system and all necessary hardware to complete the installation.

When you examine the gear ratios, first gear ends up a being a 2:1 reduction intended for slow technical crawls while the Hi Gear (28T) gear is based off the stock 1.08:1 ratio and Hi Gear Option (26T) increases top speed with a 0.93:1 ratio. Shifting through gears can be done on the fly using a 3rd channel switch on your transmitter.

Heat Treated Hardened Steel Machined Gears
The goal was to produce a gear set strong enough to take on anything thrown at it. This required a steel gear set that has been hardened, heat-treated and machined to tight tolerances for optimum performance. The 2-speed gear slider features the same treatment as the gears along with having four-tooth engagement design for accurate and rapid gears shifts on the fly.

Full Set of Cartridge Bearings
Kit includes a full set of cartridge bearings (6), which is great because while you’ve got the transmission apart it makes for a great rebuild opportunity.

Servo Options

Actuating the gear shifting can be done with either micro or standard sized servos thanks to multiple mounts offered in the kit. Axial recommends a servo with at least 80oz/in of torque to properly complete the shift. The kit features a servo saver design for increased servo longevity and two different servo horns (one long, one short) depending on servo used along with three inserts (23T, 24T, 25T) to accommodate various servo spline counts.

Within the package all necessary hardware needed to complete the installation of the 2-Speed conversion into your YETI ™ transmission is supplied, including the servo mounting screws.

  • Heat treated, hardened, and machine cut gears (18T, 28T, 26T, 36T, slider)
