Yokomo SD-118RSA Adjustable Battery Spacer — Drift Chassis Fit Solution  [SD-118RSA]

Product summary: battery mount spacer

The SD-118RSA spacer set fits under the battery mounting plate and changes its vertical position slightly. This lets you alter battery placement for clearance and balance adjustments without cutting the battery tray.

When installed beneath the mount plate, the spacer repositions the battery by small increments. That shift will influence weight distribution and body clearance for drifting applications and should be treated as a tuning accessory rather than a load-bearing component.

To install, remove the current battery plate fasteners, place the spacer(s) under the plate, then refit and tighten the fasteners making sure the threads engage fully. After fitting, inspect surrounding components for any new contact points and run cautious tests to confirm the effect on handling.

Practical reminder: use the spacer to fine-tune balance or lift the battery slightly for more clearance. Because mounting hole patterns and screw lengths vary across chassis, always confirm the mount layout and required fastener length before final assembly.
