"Direct replacement for standard units, designed to optimise handling & performance in any race or rally car.
The mechanical efficiency is greater than in a ball joint, let alone a Hardy Spicer unit, resulting in reduced power losses, and maximised engine potential. Eliminating spline lock and allowing free plunge into the inner joint gives rise to better handling & less torque steer. Made out of Aircraft spec material, as used in most international race & rally teams. Bolts onto standard Hardy Spicer output shaft, and comes complete with inner and outer cv joints."
