Tamiya 42317 - TRF419XR Conversion Kit Track-Focused Upgrade  [42317]

Take your TRF419X chassis to a track-ready TRF419XR

RC racers wanting to extract more from their Tamiya TRF419X will find the 42317 TRF419XR Conversion Kit a practical upgrade path. This conversion adapts an existing TRF419X race chassis into the TRF419XR layout to improve handling and on-track performance.

Key design changes and what they do

The kit adds carefully revised parts that sharpen both balance and driver feedback. Notable changes include a 2.25mm carbon fiber lower deck and a 2mm carbon fiber upper deck that deliver a stiff yet light platform. A centre pitch stiffener is also fitted to enhance mid-corner stability and steering accuracy for quicker direction changes.

Aluminum components that increase chassis rigidity

Durable aluminum pieces are used where stiffness matters. The package contains aluminum motor mounts, front and rear lower bulkheads, and reinforced servo mounts to reduce unwanted flex. These metal upgrades help the car hold its line and respond more predictably during high-speed sections.

Setup flexibility for different track conditions

Adjustability is a strong point of this conversion. Included front and rear stabilizers let racers tune roll and steering behaviour to suit asphalt, carpet, or technical layouts. Whether you need more front bite or a neutral balance, the parts give you the tools to refine handling.

The Tamiya 42317 TRF419XR Conversion Kit suits experienced RC drivers aiming to tune a touring car for competitive track work. Its mix of carbon and aluminum parts supports precise setup adjustments and improved handling consistency.
