Ford English Helical Blackline LSD 22 spline (standard fitment)

Blackline Helical LSD – 22 Spline (Ford English Axle)

A precision-engineered Ford English LSD designed for fast road and performance builds using the original english axle 

This English axle limited slip differential delivers smooth, progressive torque transfer without harsh locking or aggressive engagement, improving traction and stability while maintaining excellent road manners.
