Superior Tube Seals are developed to keep dirt and grime from entering the tube and destroying critical components. The seal body is made from T6 aluminum with a unique threaded design so that seals can be easily replaced if needed. These tube seals are compatible with Superior's premium axle shafts as well as stock axles. These are sold in sets of two and are anodized to protect from corrosion.

The EV90FSL fits Ford 9 Inch Axles tubes with 2.534 inch I.D.
