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

Part summary and purpose

The Yokomo YOKSD008HG MR-4TCSD H.D Suspension Arm Set is an aftermarket replacement intended for the MR-4TCSD chassis, offering a beefed-up arm option for 1/10 on-road tuning. It is supplied to fit within the stock suspension arrangement of that model.

Fitment typically follows the usual swap method used on 1/10 on-road kits: remove the wheel, detach the existing arm, transfer hinge pins and compatible hardware when possible, install the new arm, and test the suspension through its travel. Standard hobby tools are normally adequate, but confirm clearance and fit before running the car.

As a tuning part, changing to these arms will affect geometry and stiffness relative to original components and can modify steering characteristics and balance. Perform alignment checks, inspect camber and roll center under static load, and ensure pivot freedom. Use incremental changes and track testing to dial in the desired handling.

Maintenance routines remain standard: check pivots for wear, retain correct torque on hardware, and keep joints clear of dust and grit. This item is for RC model use only.
