Front one-way upgrade for Yokomo DRIFT PACKAGE

This RC-scale front one-way unit is designed for Yokomo DRIFT PACKAGE chassis and focuses on reducing rotational resistance while improving support accuracy at the front drive assembly. The unit reduces the effective inner diameter of the one-way bearing to lower rotational drag, and the aluminum housing is extended to support the bearing directly to increase alignment precision.

The kit provides the parts needed to replace or upgrade the front one-way assembly on supported DRIFT PACKAGE models, and is intended for model-level tuning where reduced drag and consistent engagement affect steering and driveline behavior during drifting.

The D-021A front one-way unit is a direct-replacement upgrade for supported Yokomo DRIFT PACKAGE models, offering a compact bearing profile and extended aluminum support to reduce rotational resistance and improve front driveline alignment for drift-focused setups.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How is the D-021A installed on a DRIFT PACKAGE front assembly?

Installation replaces the stock front one-way assembly: remove the existing housing and bearings, seat the included one-way bearing into the extended aluminum housing, fit the drive cups and gears as shown in the packing list, and secure with the supplied 2x4mm screws. Check bearing alignment before final tightening.

What items will I find in the D-021A kit?

The package contains one one-way housing, two drive cups, one ring gear, one drive gear, two O-rings and three 2x4mm screws, matching the list shown in the packing block above.

Does this unit actually reduce rotational resistance?

Yes. By reducing the one-way bearing inner diameter and supporting the bearing with an extended aluminum housing, the assembly lowers drag and promotes crisper engagement, which can change steering and driveline feel during drift maneuvers.

Is the D-021A intended for front or rear use?

This part is engineered specifically as a front one-way unit and is intended to be fitted in the front position on compatible DRIFT PACKAGE chassis.
