XRAY 306178 Graphite Battery Backstop 2.2mm Race-Tuned  [XR-306178]

Keep Your Battery Locked In for T4 2019

The XRAY Graphite Battery Backstop 306178 is built to secure the battery on T4 2019 cars, preventing lateral or rearward shift during rough landings and heavy contact. It installs on the layshaft bulkhead to add a reliable touchpoint for your pack.

Moveable Stop for Different Battery Types

This backstop can be adjusted to match the exact position of your battery, so whether you run compact LiPo bricks or taller cells you can dial in the fit. That adaptability helps maintain consistent centre of gravity and fitment across setups.

Upgrade Path with Brass for Weight Tuning

For pilots wanting a different weight bias you can replace the graphite unit with the brass version #309855. The brass part adds concentrated mass near the centre to influence handling without changing suspension geometry.
