Yokomo YOKSD008HG MR-4TCSD H.D Suspension Arm Set  [YOKSD008HG]

Overview and role

The Yokomo YOKSD008HG MR-4TCSD H.D Suspension Arm Set is an RC-scale replacement designed for the MR-4TCSD chassis to serve as an option for users seeking a heavier-duty suspension arm layout. The set is presented as a direct upgrade path for the MR-4TCSD platform and is intended to work within the standard suspension system of that chassis.

Installation follows common swap procedures used on 1/10 on-road models: remove the wheel and detach the stock arm from its mount, transfer existing hinge pins and hardware where applicable, fit the new arm, and verify free movement through the suspension travel. No specialised tools beyond common hobby hex drivers are expected for a routine replacement, but always confirm fitment before running.

In tuning terms, replacement arms like this are used to affect suspension behaviour by providing a different mounting geometry and structural characteristic compared to stock arms. Typical setup checks after installation include verifying wheel alignment, checking roll centre and camber under static load, and confirming there is no binding at the pivot points. Use incremental adjustments and test runs to assess changes in steering response and mid-corner balance.

Routine maintenance is the same as for other suspension components: inspect pivots for wear, ensure hardware remains tight, and keep pivot points free of grit. Because this item is an RC-scale accessory, do not use or reference it for real vehicle applications.
