Tamiya 42316 TRF419XR Precision Race Chassis  [42316]

Track-Oriented Design of the Tamiya 42316 TRF419XR

The Tamiya 42316 TRF419XR Chassis Kit is a stripped-down, competition-minded platform built from TRF lessons. It is focused on delivering sharper turn-in and stable high-speed behaviour for experienced on-road drivers.

Detailed Chassis Construction

This model uses a carbon fibre double-deck with a 2.25mm lower plate and a 2mm upper plate to tune torsional and pitch stiffness. The centre pitch stiffener lets you alter fore-aft rigidity to suit different surface grip and driving technique.

Robust Components and Drive System

Aluminium bulkheads, motor mount and steering components add strength where needed. The combination of front direct drive and rear gear diff, plus TRF super short big bore dampers mounted on carbon stays, provides predictable damping and consistent handling. Universal shafts ensure smooth power transfer to the wheels.

Tuneability and Race Setup

The stabiliser bars are ball-bearing mounted for accurate adjustment and repeatable changes. A fan mount is provided for cooling, and the LF battery holder can act as ballast to alter balance. Durable clamp-type wheel hubs and aluminium suspension mounts complete the package.

For drivers seeking a finely adjustable 1/10 on-road machine, the Tamiya 42316 TRF419XR provides a solid base for serious setup work and competitive testing.
