The Tamiya 42342 Aluminium Rear Uprights are crafted to refine the TRF419 chassis balance. Their 3 degree toe-in specification helps keep the rear planted during aggressive cornering and quick direction changes.
These uprights are targeted at drivers who want a firmer rearend feel without radical chassis changes. The toe-in geometry aids traction and stability during both entry and exit phases of a turn.
Using aluminium provides a tougher alternative to plastic parts while keeping mass low enough to benefit suspension performance. That durability helps with repeatable handling across race sessions.
Designed to match the TRF419 mounting layout, the Tamiya 42342 uprights allow for a clean swap from stock parts and let you get back on track with minimal setup time.
