This is a new very correct and high quality pair of pinion seals. These are correct for the MB, GPW, CJ2A, CJ3A, M38, M38A1, M170, CJ3B, and CJ5. These are a must in a vintage restoration. These fit the Dana 25 front axle and the Dana 41, 44, and 27 rear axle. I replace these on all my restorations as a fail safe. This is the first step in stopping your pinion from leaking.
