PPE Heavy Duty PTO Side Plate Cover 01-19 GM 6.6L Duramax

Made from cast aluminum, these covers add strength to center of the transmission case eliminating trans oil seepage at the mating surface. Cooling fins double the surface area (60.74 sq. in.) when compared to stock (30.62 sq. in.), therein increasing heat dissipation from the transmission oil. Kits come with the covers, mounting hardware and gaskets.
