Front One Way Version 2 Technical Overview

The 3Racing SAK-59/V2/PK front one way unit is developed for the Sakura Zero and Zero S platforms to deliver repeatable front engagement characteristics under acceleration. It provides a controllable change in front torque transfer that experienced drivers use to fine tune corner exit behaviour and lap consistency.

Technical Benefits

  • Adjustable Throttle Steering Response: The one way mechanism isolates front wheel drive during braking and engages under power, allowing setup changes to directly affect corner exit dynamics.
  • Precision Fit for Sakura Zero: Manufactured to match chassis mounting points and interface geometry to preserve alignment and gear mesh tolerances.
  • Race-Focused Durability: Components selected for endurance under repeated high load cycles and frequent maintenance intervals.

top stuff indeed very fast postage price $$$ so good as trust me sakura zero all pink all hop ups lol.....this site rocks i saved so much throught these guys you will also

What diff oil recommendations work with this one way?

Start with a medium viscosity oil and tune in 1000 to 2000 weight increments. Lighter oil increases engagement sensitivity while heavier oil smooths the transition; record changes to establish setup baselines.

How should I check gear mesh and bearing preload?

Ensure correct pinion to spur mesh using a thin business card method then tighten bearings to remove play without binding. Recheck after a run and adjust if any noise or slop appears.

Any recommended setup pairings for time attack or touring events?

Pair the one way with a slightly softer front roll stiffness and medium diff oil to prioritise consistent corner exits. For more rotation, reduce front droop or increase rear roll resistance.
