Yokomo YOKD175G is a 41T ring gear made for the Drift Package Series front one-way and solid axle configurations. Its Front x 0.69 designation reflects the effective ratio shift when used with matching pinions and diff assemblies in compatible drift chassis.
Functionally this part serves as a replacement for damaged front ring gears and as an option when tuning the front drivetrain ratio to alter handling balance. Fitment is restricted to the stated Drift Package Series front one-way and solid axle components, so verify your model matches those front parts before fitting.
Fitting advice: access the ring gear by opening the front differential or axle housing, check and set correct mesh and backlash during reassembly, and confirm the one-way or solid axle runs free. Small adjustments to mesh and shims can influence noise and lifespan, so proceed stepwise and bench-test after assembly.
