Tamiya 51639 TRF420 D Parts Carbon Reinforced Suspension Arms Kit  [51639]

Stiffened Suspension Arms Built for the TRF420

Made for the Tamiya TRF420 racing chassis, these suspension arms use carbon fiber reinforced plastic to increase stiffness and durability for demanding track use. The construction helps keep consistent handling under load and improves long term wear resistance.

Precision Tuning Options

The Tamiya 51639 suspension arms feature aluminium insert points for damper attachment, letting racers alter lever ratio by choosing different inserts (alternate inserts sold separately). This arrangement helps you fine tune handling to suit specific track layouts and tyre choices.

Rear Grip and Offset Design

Rear arms use a 3mm rear offset designed to suit the shorter TRF420 lower deck while retaining the factory wheelbase. That rear offset improves traction and rear-end stability when cornering at speed.

Fitment and Installation Notes

These arms fit TRF420, TRF419, TA07 and TB-05 PRO chassis and require 3mm diameter shafts, available separately as Item 51637. Some models may need wheelbase adjustment or spacers to account for differing offsets.
