Racing grade idler for consistent power delivery

The 3Racing Sakura D6 Aluminum Idler Gear 20T - SAK-D631 is engineered to improve drivetrain stability under sustained load on tuned setups. Manufactured with attention to gearbox alignment, this aluminium idler preserves precise gear mesh and reduces micro movement that can affect lap consistency. It is suitable as a performance upgrade or durable spare for racers refining their Sakura D6 tune.

How does this idler influence tuning choices?

A stable aluminium idler reduces drivetrain variance, allowing finer adjustments to slipper and diff settings without unpredictable gear movement affecting performance.

Should I change shims when upgrading?

Check existing shimming as aluminium may alter mesh clearance slightly; make small shim changes to achieve an optimal, low-backlash engagement for racing conditions.

Is this suitable for high RPM setups?

Yes. When combined with well-maintained bearings and correct lubrication, the SAK-D631 holds mesh under higher RPM and load, supporting more aggressive power setups.
