This is our Dodge 4 & 5 Speed Transmission Output Seal Extension. When clocking certain dodge transfer cases the 3/8" clocking ring disengages the transfer case input shaft from the transmission output seal causing a major leak. This seal extension pushes the seal back the 3/8" to compensate for the clocking ring solving the leaking issue. CNC Machined in house from 3" 6061-T6 Billet Aluminum. A new Timken seal is also supplied.
