Detailed Description

FAG SS2876 is a differential pinion seal engineered for precise fitment in a wide range of Ford, Jeep, Dodge, Mercury, and Lincoln axle applications. Its Viton sealing material is selected for durability in driveline environments, while the metal case, spring tension, and auxiliary lip help maintain sealing contact under operating conditions. The SS2876 is used where the pinion shaft passes through the axle housing, helping retain lubricant and reduce contamination at the seal surface.
