Hammer Purple Pearl Urethane 78D Bowling Ball

The Hammer Purple Pearl Urethane 78D continues one of the most recognizable and trusted urethane shapes in the game. Built for control and predictability, this ball delivers a smooth, readable arc that thrives on lighter oil conditions and shorter patterns.

Wrapped in a Urethane Pearl 78D coverstock, the Purple Pearl is designed to create consistent traction without the sharp, overreactive move associated with stronger reactive balls. Urethane naturally blends wet and dry conditions, helping reduce over/under reaction and giving bowlers a more controlled motion from release to the pocket.

At its core is the proven Super LED symmetric core, promoting a stable, low-flare motion that keeps the ball on line. This core and cover combination creates the signature smooth arc that urethane players rely on — predictable through the midlane and steady through the pins.

Finished at 500 Siaair, the surface enhances early read and control, making it especially effective on light oil or shorter sport patterns where reactive balls may hook too aggressively. Instead of sharp backend motion, you’ll see a rounded, continuous shape that keeps you in play and in control.

The Hammer Purple Pearl Urethane 78D isn’t about maximum hook — it’s about maximum control. When precision matters and you need to smooth out the lane, this is the ball you want in your bag.
