Birfield Joint (BJ)

Smooth Power Transmission at Precise Angles

High-Performance Birfield Joint

Shinhwa Auto’s Birfield Joint (BJ) is a critical type of Constant Velocity (CV) Joint, playing an essential role in a vehicle’s drive shaft. Especially in front-wheel drive vehicles, it is crucial for precisely transmitting power to the wheels, continuously and without speed changes, even while the wheels are turning through steering angles. Our high-performance BJ maintains constant rotational force even at large steering angles, enabling stable vehicle driving performance and excellent steering feel.
