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

Product overview and function

The Yokomo YOKSD008HG MR-4TCSD H.D Suspension Arm Set is a direct replacement option for the MR-4TCSD chassis, offered to users who want a more robust suspension arm layout. This set is presented as an upgrade choice for 1/10 on-road models and is intended to integrate with the standard suspension architecture of that chassis.

Typical installation follows standard 1/10 on-road procedures: remove the wheel, detach the factory arm from its mounts, transfer hinge pins and existing hardware if compatible, fit the replacement arm, and check suspension travel for free movement. No specialist equipment beyond common hobby hex drivers is usually required, but always confirm fitment prior to use.

From a tuning perspective, swapping to these arms changes mounting geometry and structural stiffness compared to stock parts, which can influence steering feel and mid-corner balance. After fitting, verify wheel alignment, static camber and roll center, and ensure there is no binding at pivot points. Make small adjustments and test incrementally to evaluate handling changes.

Maintenance is standard for suspension parts: inspect pivot points for wear, keep hardware tight, and prevent grit from entering pivots. As this item is intended for RC models, do not reference it for real vehicle use.
