Keep the dirt and grime out of your Jeep Wrangler JL Dana 44 axle tubes with RCV tube seals. The kit comes complete with 2 re-buildable tube seals, each with 3 O-ring seals on the outer and 2 washer seals on the inner. Rebuilding these seals is quick and painless. Easy access Zerk fitting is located on the sides to inject grease. Orange anodized for beauty. *Does not fit Gladiator JT Rubicon or Wrangler 392 Rubicon models Note: These tube seals do not fit over the inner splines of the JL RCV Axle Sets.  To install you will have to disengage the inner shaft from the RCV CV and install the seal into the housing while on the inner shaft.
