40137666 is an external splined shaft transmission yoke that plays a crucial role in connecting the driveshaft to the transmission. This yoke, part of the 1410 Series, features a spline count of 32 and a spline diameter of 1.378 inches. The dimensions are carefully engineered to handle the torque loads typical in high-performance applications while maintaining compatibility with standard driveline components.
The 9.055-inch centerline to end measurement ensures proper fitment in various setups, allowing for smooth operation and effective power transfer. When replacing a yoke, it’s essential to check the spline engagement depth and ensure proper phasing with the opposite yoke to avoid driveline vibrations.
