Shooter Spring Cross-Reference

Shooter springs come in various strengths. Used games frequently have the wrong spring (ops want to keep the game earning and will substitute what they have on hand).

These are effectively interchangeable between manufacturers, but the “colors” are not consistent. This list might help.

* 10-148 listed in this Pinside thread but I can’t find it in modern part lists. (Seems credible.)
** 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.

Bally games: all SP-200-24, which is NLA. Use equivalent 10-148-4 or A-348.

On some games (Black Knight 2000) shooter springs are important 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. On my Twilight Zone, I need the shorter barrel or the rod didn’t impact the ball.

A-348 is probably the right choice for any game from before 1990.


I got most of this from Marco Specialties’ web site catalog but I did compare a few Stern manuals and two other vendors.

WPT manual says 266-5001-07 is green but lists two green springs; AC/DC says blue for this number.
