Yokomo YOKD175G is a 41-tooth ring gear intended for use in the Drift Package Series front one-way and solid axle assemblies. The Front x0.69 marking indicates the effective drivetrain ratio change when paired with the correct pinion and differential elements on compatible drift chassis.
This ring gear functions as a direct replacement for damaged front gears and as a tuning option to modify front drivetrain gearing for handling balance. Confirm your chassis employs the Drift Package Series front one-way or solid axle before purchasing, as fitment is specific to those front components.
Fitting notes: remove the front differential or axle housing to access the ring gear, set and verify gear mesh and backlash on reassembly, and make sure the one-way or solid axle runs freely. Careful, incremental mesh and shim adjustments will influence noise levels and component life; bench testing after installation is recommended.
