Pappy, the best of my knowledge, it is a sterling 10.25" rear. I have the MagHytec cover on my Dana80, and really like the ease of maintenance, and the provision for a diff temp guage. The diff temp guage will surprise you at the readings. One thing about the fill level on the dipstick, I only fill the rear to the bottom mark, or just a hair over. The top mark level seems to overfil the diff. Mine filled to that level will usually create a leak at the left axle seal.The downside to the MagHytec cover is, guys will admire your rear.
