Tamiya 42317 TRF419XR Conversion Upgrade - Lightweight Decks  [42317]

Convert a TRF419X into a more responsive TRF419XR

Enthusiasts looking to ramp up performance on race day can use the 42317 TRF419XR Conversion Kit to rework a Tamiya TRF419X chassis. The conversion reconfigures the platform to the TRF419XR specification to deliver crisper handling on tight and flowing tracks.

What the TRF419XR brings to handling

The pack replaces key chassis parts to refine balance and steering feedback. Included are a 2.25mm carbon fibre lower deck and a 2mm carbon fibre upper deck that cut weight while keeping torsional stiffness. A centre pitch stiffener is fitted to stabilise the car through mid-corner transitions and improve turn-in precision.

Where aluminium upgrades matter

The conversion uses aluminium in critical locations to reduce flex. Aluminum motor mounts, front and rear lower bulkheads, and servo mount pieces increase the chassis stiffness where it affects traction and steering response the most. The result is a firmer, more predictable platform.

Tuneable parts for track-specific setups

Racers benefit from a range of setup options when running this conversion. Front and rear stabilisers are provided so you can dial roll and understeer levels to match surface grip and corner types. Small changes to those elements result in noticeable shifts in handling balance.

The Tamiya 42317 TRF419XR Conversion Kit is best for racers who already know setup basics and want a lighter, stiffer touring chassis. Its component selection supports precise tuning for different track surfaces.
