JF015E Upper Primary Piston
The TransGo CNC machined billet steel upper primary piston is much less prone to deformation and wear then the soft OE piston. Also, to help prevent the piston from coming loose again on the pulley, the inside diameter of the piston is smaller than the original design, resulting in greater interference fit. This is a quick and easy fix to eliminate pulley pressure loss as well as belt slip complaints without the need for any special tools. This billet piston MUST BE PRESS-FIT, or it will leak. A 2-1/4 socket works well for pressing this new piston down onto the primary pulley.
