The main power spring drives the throwing arm on your Blue Flame or Black Flame pitching machine, and it’s the part that most affects pitch speed as it wears. This genuine UPM45 replacement spring restores full velocity and a consistent, repeatable release.

Compatibility: Fits both the Blue Flame and Black Flame pitching machines.

Genuine Louisville Slugger replacement part. Keep a spare on hand so a worn spring never cuts practice short. Free shipping on orders over $99.
