The XRAY 325316 rear drive shaft is a core replacement part for the XT4 platform, machined to 92mm with a 2.5mm pin for accurate fitment. Built from Hudy Spring Steel, the shaft is heat-treated for strength and designed to resist wear during frequent track use, making it a sensible upgrade for serious drivers.
Hudy Spring Steel undergoes a precise hardening process that improves toughness and fatigue resistance. That results in fewer failures under load and more consistent power transfer from the motor to the wheels, helping keep your car predictable lap after lap.
Specifically dimensioned for the XT4 series, the XRAY 325316 rear drive shaft installs cleanly into the stock drivetrain layout. Its accuracy reduces slop in the system and supports reliable handling and drivetrain longevity after installation.
