The 3RACING TA05-IF13/LB rear aluminium stiffener is a tuning component aimed at improving rear chassis stiffness on Tamiya TA05-IFS and TA05-R platforms. It provides a reliable way to reduce unwanted rear flex so drivers can tune suspension and diff settings with greater consistency.
When using this stiffener, expect crisper feedback from the rear axle during cornering. It is suited to drivers who adjust roll centre, anti-roll balance, or differential preload and want a more repeatable baseline from the rear of the chassis.
Installation follows standard mounting points and requires common tools. After fitting, verify alignment and fastener torque as part of regular maintenance to maintain predictable race performance.
