This aluminum left mount block has been produced for 1/12 on-road competition and serves as the left front replacement on YR-X12 series chassis.
Role in setup: the block determines the left front suspension mounting geometry and thus influences tuning outcomes such as front-end response and roll balance during race tuning.
Compatibility statement: confirmed fit for YR-X12 and YR-X1219 chassis. It is supplied as the left front block only and intended for RC scale 1/12 competition cars.
Fitting tips: designed to align with YR-X12 series mounting points so it replaces the existing left front block; ensure correct hardware torque and alignment checks after installation to retain intended geometry.
