Engineered for the X4F chassis, the XRAY 306134 Aluminum Battery Positioning Backstop is machined from Swiss 7075 T6 aluminium for a firm yet lightweight mounting point. It prevents unwanted battery shift while you push the car on demanding layouts.
The CNC finish provides a repeatable fit so you can move the battery to fine-tune weight bias. Those small changes can make a noticeable difference to mid-corner balance and traction under power.
If you work on setup and seek stability lap after lap, the XRAY 306134 Aluminum Battery Positioning Backstop is a worthwhile upgrade to secure and optimise your X4F battery placement.
