Tamiya TA07/TB04 Pro II Precision Front Arms JR-TA706-GU by Jazrider  [JR-TA706-GU]

Tuning benefits overview

This is an aluminum replacement intended for the front lower suspension arms on Tamiya TA07 and TB04 Pro II chassis. The JR-TA706-GU items arrive in a gun metal anodized finish and give a firmer connection point compared with stock plastic arms, useful when tuning handling balance.

They are made as direct swap parts for the listed Tamiya models and retain the original suspension geometry. When fitting, make sure pivot pins align correctly and confirm there is clearance for steering links and uprights. Standard hex drivers and pliers are usually enough for the swap.

Used as a tuning upgrade, these alloy arms reduce chassis flex at the front and help produce a repeatable feel as suspension settings are changed. Check all mounting hardware during installation and re-verify toe and roll-center after first test running.
