Tamiya 51638 TRF420 Front Upright Set C-Parts  [51638]

Stiffen your TRF420 with Tamiya 51638 carbon-reinforced uprights

The Tamiya 51638 TRF420 C-Parts are front uprights moulded from carbon fiber-reinforced plastic to increase structural stiffness and resist wear. They suit hobbyists who need reliable, track-ready components for repeated use.

Which kits work with these uprights

Although intended for the TRF420, these uprights also fit other Tamiya platforms such as the TRF419, TA07, and TB-05 PRO. That compatibility helps when you run different models but prefer the same upgrade parts.

Service-Friendly Two-Part Layout

The uprights use a two-part assembly that separates the arm from the bearing carrier. This lets you replace bearings or tweak geometry without removing the entire assembly, speeding up pit-side repairs.
