Cast Aluminum

One of the rarest, yet "cool" options for the 1970-72 4-4-2's was the W-27 aluminum differential cover option. It held more fluid and was made of aluminum, so it kept the rear gear oil cooler, thereby increasing gear and posi-life. These are top-quality duplicates of the original W-27 rear covers. Proudly manufactured in the USA.
