CANTONÍS Universal Screen Windage Tray kit allows you to install a screen windage tray in almost any application. The screen windage tray delivers oil control and horsepower savings. The one-way screen design allows oil coming off the crank to pass through the screen while not allowing the oil in the sump to reach the rotating assembly. This kit includes a 22" x 12" sheet of one-way screen, two 1" x 1/8" x 24" mounting rails, and all necessary clips, washers and locking screws needed. Welding is required.
