A pearl in the realm of bowling excellence.

As someone who's experienced the thrill of rolling the Deadly Rattler down the lanes, I can confidently say it's a game-changer. The pearl version of the original Rattler, equipped with the cutting-edge HK-22 cover, sets a new benchmark in the world of bowling. The HK-22 cover ensures a cleaner projection through the front part of the lane, and the down-lane motion is nothing short of spectacular – a significant upgrade from the already impressive original Rattler.

What sets the Deadly Rattler apart is its ability to combine the tried-and-true core of the original Rattler with an RG of 2.48 and a differential of .035. This fusion creates a venomous one-two punch on the lanes. The Deadly Rattler not only maintains the essence of its predecessor but elevates the game with a sharper and more continuous down-lane motion. It's not just a bowling ball; it's a dynamic force that transforms the bowling experience. If you're seeking a powerful and precise tool to up your game, the Deadly Rattler is the answer – a pearl in the realm of bowling excellence.

Deadly Rattler

he Deadly Rattler
I’m a left handed bowler. With a ball speed around 14.5 mph. My Rev rate is around 275rpms. I recently punched up the new piece of equipment. My layout choice is 70 x 3 1/2 x 20. With the HK22 cover on it. It is clean through the front part of the. And has a very continuous backend motion. This layout and ball allows me to get deeper. When the shot opens up. If you’re looking for a ball for light to medium condition. Well this would be a great choice. It is a great addition to the Radical Bowling Technology.

Radical Deadly Rattler

I picked up the Deadly Rattler because the first Rattler became one of my favorites when it came out last year. A smooth motion ball that carried. As soon as I threw this ball, I recognized the shape it created. It reminded me not of the Rattler, but another of one my favorites from the Track line-up, the Sensor Pearl. I did a little looking and the numbers are really close & the cores (Regulator & Rattler Symmetric) are very close in shape. Yes!!! A ball I already liked and now it has HK22 thrown into the cover??? Awesome. Super clean through the front, not flippy, and very continuous. Then you have the Red & Silver that mesh really well and look great going down the lane. I see this ball working great on shorter patterns, low volume patterns, for higher rev players, or any time the lanes starts to hook. I Like it!!

The deadly Rattler is very deadly

How do you make one of the best Symmetrical balls even better you add HK22. I drilled mine 60x5x30 same as my Rattler and it was cleaner and stronger.this one is quickly becoming one of my favorites.

Radical Deadly Rattler review (with video)


The Radical Deadly Rattler is the pearl complement to the phenomenal Rattler Solid. The Deadly Rattler uses an HK22 base pearl resin coverstock and the rattler symmetric core to give bowlers length and continuation on most medium, to medium heavy, oil patterns. I drilled my Deadly Rattler 70 x 4.5 x 35 for a true benchmark layout, and this ball delivers big time. I get about 2-3 feet more length than the original Rattler Solid, and a sharper angle off the spot. It is a great 1-2 punch when you want control mixed with performance. I have used it on Kegel Stone Street and Beefy Burrito (sport pattern) with great success on each. The Deadly Rattler releases 10-19-2023 and is available for pre-order now from Bowler Builders Pro Shops. Get your hands on a true benchmark symmetric pearl and join the Radical Revolution today! Here is the three-shot video of the Deadly Rattler:

Deadly Rattler

I drilled mine 4 ¾ by 30 looking for increased downlane motion and this ball did not disappoint. I was hoping for later and quicker response to the friction along with continuation compared to the OG Rattler. The Deadly Rattler delivers this and then some.
