Refined Track Performance for On-Road Racing

The Tamiya 84339 TB-04 PRO Chassis Kit evolves the TB-03 concept into a more track-focused platform. It uses a shaft-driven 4WD system and a horizontal motor mount to lower the center of gravity, delivering improved balance and more consistent lap times for serious on-road drivers.

Heritage Design with Modern Upgrades

Built on ideas from successful Tamiya models such as the TA-05 Version II and the TRF 416/417 line, the TB-04 PRO retains a fully independent double wishbone suspension while introducing revised components for steadier handling and better traction through turns.

Setup Options for Precise Tuning

Adjustability is a core strength of the TB-04 PRO, allowing fine tuning of camber, toe, ride height, gear ratios, wheelbase, track width and shock angles. The redesigned transmission case and gear differential improve drive stability during acceleration, and the longer steering tie-rod layout gives more accurate steering response.

The Tamiya 84339 TB-04 PRO Chassis Kit fits hobbyists who value a tunable on-road chassis. Its blend of proven suspension geometry and refined drivetrain parts makes it useful for racers refining setup and for builders who want a competitive base platform.

How does the TB-04 PRO improve on the TB-03?

The TB-04 PRO updates motor placement and trans housing design while refining internal gears and suspension parts, resulting in improved center of gravity and steadier handling over the TB-03.

What electronics do I need to complete the kit?

This is an assembly kit and does not include motor, ESC, servo or radio gear. Choose a compact horizontal-mount motor and a low-profile servo to match the chassis layout and preserve balance.

Is the TB-04 PRO suitable for a newcomer to on-road racing?

Beginners can build and run the chassis, though some setup knowledge helps. Start with conservative camber and toe settings and standard shock oil to keep handling predictable while you learn tuning basics.

What tyres work best on this chassis?

On-road slicks or low-profile grippy tyres designed for touring car layouts work best. Match tyre compound to track surface and use small toe or camber tweaks to optimise grip and steering feel.
