Tamiya 42317 TRF419XR Conversion Kit Race Setup Pack  [42317]

Upgrade your TRF419X to the race-oriented TRF419XR

Builders seeking more precise handling can convert a Tamiya TRF419X using the 42317 TRF419XR Conversion Kit. The transformation gives the chassis a firmer platform and better steering characteristics suited to close competition.

Major changes in chassis construction

The conversion implements parts that raise overall stiffness and refine balance. It fits a 2.25mm carbon fibre lower deck and a 2mm carbon fibre upper deck to reduce unwanted flex while keeping mass low. A centre pitch stiffener is included to enhance rotation and mid-corner control.

Where aluminium makes a difference

Strategic aluminium pieces strengthen critical mounting areas. The kit supplies aluminium motor mounts, front and rear lower bulkheads, and improved servo mounts to limit flex where it counts. These upgrades produce a more stable platform under braking and acceleration.

Fine adjustment options for track tuning

The kit offers multiple tuning levers for handling refinement. Front and rear stabilisers allow precise changes to roll response and steering feel, enabling drivers to tailor the setup to different surfaces and corner types.

The Tamiya 42317 TRF419XR Conversion Kit is recommended for experienced hobbyists focused on race performance. Its carbon and aluminium parts help create a tunable, competition-ready touring chassis.
