Durable Aluminium Idler for Improved Drivetrain Feel

The Yokomo Y2-503IAA aluminium idler gear is made to refine the drivetrain of YD-2 cars. Precision machining and a protective hard coat produce consistent tooth profiles and reduced wear, resulting in a smoother power delivery. It is an effective upgrade for drivers seeking greater drivetrain stability without major setup changes.

Where It Fits and What It Helps

This idler is compatible with many YD-2 variants and is suited for racers and hobbyists who demand dependable drivetrain parts. Its firmer construction reduces flex in the gear train, which can translate to crisper throttle response and steadier cornering behaviour.
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.

Is this idler a direct swap for stock plastic units?

In most cases yes, the Y2-503IAA fits as a replacement for common YD-2 stock idlers. Verify shaft and mount compatibility first.

Does aluminium add noise compared to plastic?

Aluminium can produce a slightly different tone, but correct mesh and lubrication keep noise minimal while improving consistency and durability.

Can I run this idler on touring car setups?

Yes, it is suitable for touring and drift YD-2 based setups where a rigid idler helps maintain drivetrain alignment and predictable handling.
