X4 Series Carbon Battery Plate Shim (2) for secure mounting - XRAY 306175-C  [XR-306175-C]

Carbon Battery Shims (set of 2)

This set contains two carbon battery plate shims made for precise RC battery mounting. Each shim is countersunk so screw heads sit flush and they suit thinner chassis areas where extra spacing or a tighter fit is needed.

Produced by CNC machining from high-grade carbon fiber, the pieces act as a rigid, lightweight spacer to stabilize the battery tray and limit unwanted movement under cornering and acceleration. Use them as a tuning accessory to adjust battery fitment and clamp pressure rather than as a structural change.

Fitting is simple: place the shim between the battery plate and chassis or battery bracket, align the countersunk holes with the mounting screws, and tighten as normal. Verify screw length and engagement to prevent over-tightening on thin chassis sections.
