Front drag-reducing one-way for DRIFT PACKAGE

This scale front one-way unit is made for Yokomo DRIFT PACKAGE chassis with the aim of lowering rotational friction and tightening bearing support at the front drive. The design shrinks the effective inner diameter of the one-way bearing to reduce drag while the longer aluminium housing supports the bearing for improved alignment.

The set includes all parts required to replace or upgrade the front one-way assembly on supported DRIFT PACKAGE platforms, targeting hobbyists who tune driveline engagement and steering feel for drifting.

  • One Way Housing - 1 pcs
  • Drive Cup - 2 pcs
  • Ring Gear - 1 pcs

As a direct replacement, the D-021A provides a tighter bearing profile and extended aluminium support to lower rotational resistance and refine front driveline alignment on compatible Yokomo DRIFT PACKAGE cars.
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.

Will D-021A fit my specific DRIFT PACKAGE model?

Check the Compatible Models list above; the D-021A covers a wide range of DRIFT PACKAGE and DP-series chassis. If your model appears in that list, the unit is intended as a direct-replacement front assembly.

What components are supplied in the box?

The box contains a one-way housing, two drive cups, a ring gear, a drive gear, two O-rings and three 2x4mm screws as outlined in the packing section.

How does the housing extension improve alignment?

Extending the aluminium housing provides direct support to the one-way bearing rather than relying solely on peripheral mounts. This increases concentricity and reduces misalignment, which helps maintain consistent engagement under load.

Is specialist tooling required to fit this unit?

Basic RC tools such as small screwdrivers and precision pliers are sufficient for installation. Careful bearing seating and correct torque on the supplied screws will ensure correct fitment.
