High-retention seal for full-float axle tubes with a 2.5"" I.D.
This 2.5"" inner axle seal is built specifically for full float rear ends or front ends running 35 spline D60 shafts or Toyota-style 1.31"" shafts. It’s a press-fit style with no slop — eliminating the leak issues you’ll run into with looser seals. We’ve designed this with three O-rings on the housing to lock it in place, and the replaceable inner seal itself features a double-lip design to give you two seals per side — effectively four per axle.
These are ideal when running a grease-packed setup at the hub, like you'd do on the front of a Dana 60. Semi-float setups that rely on oiling the outer bearings aren’t the right match here. Available for 2.5"" axle tube I.D. only. Sold individually.
