Features

  • Poppet spring for shift rod locking Dana 18
  • Ensures transfer case stays in gear
  • Prevents unexpected jumping out of gear
  • Used with poppet ball and plug
  • Compatible with Dana 18, Dana 20 and Dana 300 transfer case

★ Replace this spring in good time to prevent problems with gears jumping out. A weakened spring can prevent the transfer case from locking properly.

Application

Dana 18 transfer case (1941-1971), Dana 20 transfer case (1962-1979), Dana 300 transfer case (1980-1986). Fits vehicles with these transfer cases as listed in the product categories.

Installation notes

Remove the poppet plug from the front output bearing cap. Replace the spring together with the poppet ball if necessary. Ensure the plug is properly tightened to prevent leakage. During disassembly: take care with the bullet-shaped interlock pin between the shift rods.

Compatibility

Universal for Dana 18, Dana 20 and Dana 300 transfer cases. Two poppet springs are required per transfer case (one on each side of the front output bearing cap). Not to be confused with the anti-rattle shift lever springs that are located on the shift levers themselves.

Historical context

The Dana 18 transfer case was standard equipment in Willys and Jeep vehicles from 1941 and was produced until the early 1970s. The poppet spring is a critical component of the shift detent system that provides reliable gear locking.
