When working on an XRAY T4 2020 car, the XRAY 971050 silicone O-ring set is a handy spares pack. These 5x1.5 rings slip over 5mm shafts and are useful for routine servicing and minor upgrades.
The O-rings are tailored to the T4 2020 Specs (300026, 300027) and slot into the same locations as the original seals. They provide a tight interface that helps reduce unwanted movement and extend part life.
Silicone keeps its shape and flexibility over time, resisting wear from heat and repeated use. That resilience makes these rings a sensible choice for performance-minded RC setups.
