MR-4TCSD LCG Aluminum Swing Shaft Support - YOKSD644A by Yokomo  [YOKSD644A]

Swing Shaft Support for Durable LCG Setup

The Yokomo YOKSD644A LCG Aluminum Shaft Holder is an aluminium swing shaft support designed for MR-4TCSD low-centre-of-gravity builds. It locks the drive/swing shaft assembly into a firmer position, using machined aluminium to reduce flex while keeping weight close to the chassis centre.

Fitment and role: this holder replaces the standard MR-4TCSD swing shaft bracket to change shaft height and improve driveline alignment. It is suitable for hobbyists seeking incremental LCG adjustments that refine handling without major chassis rework.

Installation notes: installs into the original MR-4TCSD swing shaft location and uses the factory mounting points and screws. During fitting, confirm bearing seating and shaft play, apply even torque to fixings, and ensure free rotation before reinstalling gearbox and suspension. Inspect fastening threads and bearing clearances after initial test runs and after any impacts.

Maintenance and tuning: aluminium demands routine care—look for dings, burrs or matched contact marks after use, and re-check alignment if you alter gear sizes. Adjustments to holder position can influence roll stiffness and throttle feel, so make measured changes and note outcomes.

For MR-4TCSD drivers focused on durable LCG upgrades, the YOKSD644A is a tough aluminium option that helps control shaft height and improves drivetrain alignment without rebuilding the chassis.
