Keep the dirt and grime out of your Dana 30 and 44 axle tubes with RCV Dana 44 axle 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. Red anodized for beauty. Note: These tube seals do not fit over the inner splines of the CVJ44-JK-35 axle. However, it is possible to disengage the inner shafts from the CV joints and slide the tube seals on from the other end CV. If you are purchasing the axles at the same time as the seals, let us know and we can ship the axle set with the tube seals already on the shafts. Fits all standard wall Dana 30 & 44 axle tubes (2" bore diameter). Will not fit in Dynatracs 44 ProRock with 3"x.313" tubes or Teraflexs Tera44 3.25"x 1/4" axle tubes. Please see D44SK-PROK & D44SK-TFLEX for those options.
