Built specifically for the XRAY T4 platform, the XRAY 305138 Solid Axle ECS BB Driveshaft Adapter is a precision upgrade aimed at improving axle reliability. Constructed from HUDY Spring Steel, the two-piece set resists track wear and keeps handling predictable lap after lap.
XRAY 305138 adapters are CNC-machined to deliver a snug interface with ECS BB driveshafts, reducing play and improving drivetrain feedback. The consistent geometry helps maintain balance under braking and acceleration.
These adapters match ECS BB driveshaft specifications and are intended as direct upgrades for XRAY T4 cars. Swap-in installation is quick for experienced builders and requires minimal setup changes to re-establish handling balance.
