The Mittler Bros. GN Rear Axle Seal is the axle seal used in Mittler Bros. / Tanner GN rear hub assemblies — standard, lightweight, and off-road configurations. It seals the axle side of the hub to protect the bearing and hub internals from dirt, debris, and contamination. One seal per hub.
Included in the GN Rear Hub Accessory Kits (SKU 1400-400-R/L) and all complete rear hub kits. The companion hub seal is sold separately as SKU 1400-510. Always replace both the axle seal and hub seal together during hub service. Sold individually. Made in the USA.
