Prime your Harley lifters with less mess and more consistency. The Lifter Primer is a simple vacuum-jar tool designed to help pull trapped air out of hydraulic lifters and encourage oil to fill where it needs to—so you’re not relying on guesswork, soaking, or hoping the first startup sorts itself out.
Why you’ll want it
Cleaner priming (no oil bath / less spill)
Helps remove air and improve oil fill
Repeatable process you can do at the bench
Built for DIY builders and garage mechanics
How it works (simple)
Fill the jar with oil, place the lifter in the holder, and pull vacuum through the valve stem using your hand vacuum pump. As air escapes, oil can move into the lifter more effectively.
