Fit a steel idler for tougher duty

The Tamiya 33T steel idler is a practical upgrade for RC models built on BB-01, TD2/TD4 and XV-01 frames. Replacing the stock plastic idler reduces deformation and helps the drivetrain hold up under aggressive driving.

Which chassis work and how to install

This 33T steel idler is designed for seamless use in BB-01, TD2/TD4 and XV-01 chassis. Swapping out the original MA27 plastic idler is straightforward; just check alignment and clearances as you refit the steel unit.

Performance advantages from metal gears

Metal idlers withstand higher loads and abrasion better than plastic, delivering steadier gear engagement and fewer replacements over time. Steel helps keep gear mesh tighter under load, which benefits lap-to-lap consistency.

Will swapping to steel affect noise levels?

Steel can transmit more mechanical noise than plastic, but correct mesh and light lubrication will keep noise acceptable while improving longevity.

Do I need to change the idler shaft or bearings?

You can reuse the existing shaft and bearings if they are in good shape. Replace worn bearings to ensure the steel idler runs true and does not introduce side load on the gearbox.

Is this suitable for bashing and recreational off-road use?

Yes. The steel idler is well suited to bashing and rough surface running, as it resists the wear and impacts that typically shorten plastic idler life.
