The XRAY T4F Aluminum Solid Layshaft is a CNC-turned upgrade part aimed at improving drivetrain behaviour on T4 cars. Machined from quality aluminum, it trims rotating weight while preserving necessary stiffness. Its precision hollow bore guarantees roundness to limit drivetrain vibration and promote balanced rotation. The flat spur gear mount reduces gear oscillation for reliable power transfer lap after lap.
A practical upgrade for drivers seeking consistent handling and cleaner drive inputs in XRAY T4F cars, blending low mass with long-term durability.
