Tamiya TRF421 Rear Upper Deck - Split Graphite 2mm by Factory Pro O-TCP005  [FP-O-TCP005]

Split Rear Upper Deck Compatible with TRF421

This Factory Pro split rear upper deck has been developed as an aftermarket hop-up for the Tamiya TRF421 chassis. Machined from 2mm graphite, the replacement plate adjusts rear section stiffness while using the TRF421's existing mounting points.

Installation is simple for those familiar with TRF421 upkeep: remove the OEM rear upper deck, position the split graphite piece on the original screw locations, and reinstall the stock fasteners. No chassis modification should be necessary when the plate is installed correctly.

Think of this item as a precision tuning part. Fitting a harder 2mm graphite rear upper deck alters chassis flex characteristics during acceleration and turns, so combine it with measured adjustments to dampers, sway bars and toe to achieve the balance you are after.
