OE-Style Differential Pinion Seal for Dana Axles

The Dana Spicer FSGR 50660 differential pinion seal is built for Dana 30 and Dana 44 axle applications that need a precise sealing surface at the pinion. With a rubber construction and a 1.552 in inside diameter, this seal is sized for front and rear axle service on a wide range of Jeep, Ford, GMC, Chevrolet, and Isuzu vehicles.

Genuine Spicer light vehicle axle components are produced to OE-level standards because they are OE parts. That makes the 50660 a direct replacement choice for drivers and technicians looking for consistent axle sealing performance on Dana 30 and Dana 44 setups.
