Those tuning an XRAY RX8e will recognise the value of the XRAY 343077 Graphite Belt Tensioner Holder as an upgrade that tightens belt behaviour. The graphite part supports smoother torque transfer and stabilises belt tracking during fast laps.
Graphite construction reduces component flex and keeps the belt running true, which matters when torque spikes on acceleration. The stiffer assembly helps reduce belt oscillation and keeps drivetrain reactions consistent for better lap-to-lap performance.
Made specifically for the XRAY RX8e family, this holder aligns with the standard layout so it can be fitted quickly. The simple installation route means less bench time and more on-track testing after the upgrade.
