The Yokomo YOKD175G is an RC-scale 41T ring gear intended for the Drift Package Series front one-way and solid axle assemblies. Its designation (Front x 0.69) identifies the effective ratio change when used with the matching pinion and differential arrangements in the front drivetrain of compatible drift setups.
This part serves two practical roles: replacement for worn or damaged front ring gears, and a tuning option when adjusting overall front drivetrain ratio for handling balance. Fitment is limited to the Drift Package Series front one-way and solid axle configuration as stated, so verify your chassis uses those front components before installing.
Installation notes: standard disassembly of the front differential or axle housing is required to access the ring gear, check gear mesh and backlash after reassembly, and confirm the one-way or solid axle functions smoothly under rotation. As with other RC components, small adjustments to mesh and shimming can affect noise and durability, so make incremental changes and test on the bench before track runs.
