Blue Flame Pro Replacement Spring

The power spring is what gives the Blue Flame Pro its 30–58 mph range, and springs are a natural wear item on any manual machine. This genuine replacement spring restores full velocity and the crisp, consistent release your Pro was built for.

Compatibility: Fits the Blue Flame Pro (UPM55 / L60050) pitching machine.

Genuine Louisville Slugger replacement part. Keep a spare on hand so a tired spring never ends a session. Free shipping on orders over $99.
