The Yokomo YOKD175G is a 41-tooth ring gear built for the Drift Package Series front one-way and solid axle assemblies. Labeled Front x 0.69, it produces a measurable change in front drive ratio when combined with the proper pinion and differential arrangements on compatible drift rigs.
Use this component as a replacement for worn front ring gears or as a tuning part to modify front drivetrain ratio and tune handling characteristics. Compatibility is limited to the Drift Package Series front one-way and solid axle configuration, so double-check your chassis uses those front parts before installation.
Installation guidance: disassemble the front differential or axle housing to reach the ring gear, then set gear mesh and backlash correctly during reassembly. Confirm the one-way or solid axle rotates without binding. Incremental shim and mesh adjustments will affect noise and longevity, so test progressively on the bench.
