MR-4TCSD Compatible LCG Shaft Holder - YOKSD644A by Yokomo  [YOKSD644A]

MR-4TCSD Shaft Positioning Component

The Yokomo YOKSD644A LCG Aluminum Shaft Holder is a precision-machined aluminium support crafted for MR-4TCSD low-centre-of-gravity setups. It functions as a fixed mount for the drive/swing shaft assembly and concentrates mass toward the chassis centreline to aid handling refinement.

Fitment and role: this holder replaces the stock swing shaft bracket on MR-4TCSD platforms to change shaft height and improve driveline alignment. It is aimed at hobby tuners who want subtle vertical changes to swing shaft position to improve balance and reduce friction from misaligned components.

Installation notes: fits into the existing swing shaft location and uses the original MR-4TCSD mounting points and fixings. During fitting, ensure bearings are correctly seated, verify shaft play, tighten fasteners evenly and confirm free rotation before reassembling the gearbox and suspension. Re-check bearing clearance after initial test runs and make small corrections if needed.

Maintenance and tuning: aluminium construction requires routine inspection—look for contact marks or burrs after running, and confirm alignment if you alter spur or pinion sizes. Incremental adjustments to the holder can affect roll behaviour and throttle feel, so test methodically and note outcomes.

Owners of MR-4TCSD chassis seeking controlled shaft-height tweaks and improved driveline geometry will find the YOKSD644A a compact aluminium upgrade that aids LCG tuning without altering the main chassis layout.
