Shooter Spring Cross-Reference

Shooter springs come in a wide variety. Used games, particularly those that were operated, frequently have the wrong spring. This is a cross-reference for figuring out what will work in what situation since the colors aren’t consistent across manufacturers. I got most of this from Marco Specialties’ web site catalog but I did compare a few Stern manuals.

On some games (Black Knight 2000) this matters because a strong spring is required to launch the ball into play. On other games (Twilight Zone) a weak spring is required for greatest precision. On my Simpsons Pinball Party, the documented diameter wasn’t enough and I went to a stronger spring.  And then there are games like WPT which are pretty open-minded and will work with whatever you find in your junk drawer.

One other important question: is the barrel spring on the outside of the cabinet the one you want? There are a couple different ones, and a couple different shooter rod lengths. They don’t differ by much, but it can matter.

  • ? 10-148 listed in this Pinside thread but I can’t find it in modern part lists. (Seems credible.)
  • ** WPT manual says this is green but lists two green springs; AC/DC says blue so I’ll go with that
  • *** Simpsons Pinball Party: I got the Williams equivalent for this but I didn’t find it strong enough to make the Apu shot, so I went one spring stronger.

  • actionpinball.com (might have some listed twice?)
  • bayareaamusements.com
  • marcospec.com (I like their spring kit)
  • Stern’s AC/DC and WPT manuals list different colors for different springs. I took a look at several manuals and picked the values that looked the least bogus. I would consider buying by the Williams part number.
