Upgrading an XRAY RX8e with the XRAY 343077 Graphite Belt Tensioner Holder tightens up belt behaviour to give cleaner drivetrain response. The graphite unit is intended to stabilise belt tension for more predictable power delivery on circuit runs.
Graphite increases structural stiffness without adding bulk, which reduces flex in the tensioner area. The result is steadier belt tension under acceleration and braking, lowering the risk of belt movement that can upset handling.
This holder is tailored for the XRAY RX8e platform and fits with standard hardware, so hobbyists can replace the stock item quickly. The simple installation makes it a practical upgrade for those refining on-track performance.
