Race car differentials play a critical role in distributing engine power to the drive wheels while allowing them to rotate at different speeds during cornering. Performance and motorsport differentials are designed to improve traction and handling, especially under hard acceleration and high cornering loads. Many racing setups use limited-slip or locking differentials to maximize power delivery and stability on track. Motorsport Locker provides a marketplace where racers and builders can buy and sell new and used race car differentials designed for motorsport and high-performance applications.
