6.75oz lighter than P/N 87-9469-B 108mm O.D., .875" Balls, 28 Spline Inner Race The I.D. of the 6 mounting holes are 10.4mm. (The fit between balls and tracks is very loose to allow for maximum angles)
Larger C.V. Joints make it possible to run increased loads and axle angles, but in turn add to the mass rotating weight. Reducing this weight can improve acceleration, much like lightening the engine flywheel. EMPI's Hi Performance Lightened C.V. Joints offer all the quality benefits a Hi-Performance C.V. Joint should. They include Chromoly Cages and hardened alloy inner/outer races that are precision machined ground and hand inspected. A reduction in weight as a result of custom machining the O.D. of the outer race adds the finishing touch for a true hi-performance C.V. Joint. This machining process also aids in cooler operating temperatures of the joint in extreme use situations.
