    The Ebonite GB4 is your best new benchmark ball. It is an absolutely incredible ball and is your ideal league/tournament (medium to heavy oil) and sport/challenge shot ball. This ball should never leave your bag! It has a controllable shape, but has strong continuation through the pins that will help you carry a lot! The history of the Game Breaker series is one in its own and continues to be a fan favorite! Drilled mine 55 x 4.5 x 30.

    A super strong ball that is perfect for playing the lanes straighter. At first I thought this ball would be too much, but after a handful of games it has shown too be one of my benchmark pieces!

    Great Benchmark Ball!

    The Ebonite GB4 has been a great benchmark ball for me. It’s the first one out of my bag every time. I’d recommend the GB4 if you’re looking to add a new benchmark ball to your arsenal.

    The Ebonite Game Breaker 4 is truly a benchmark ball! It's can be your first ball out of your bag to get the best read on the oil condition. The Game Breaker series has been a fan favorite and know it's even better. Box finish is 500/1500 which helps this ball read lane and gets you to play in more oil. It's a motion that you can see and depend on. Talk about smooth and continuous! It also takes surface changes very well. To much mid lane the shine it up, not enough then take the surface down even more. Great price, great looking ball and it's a Game Breaker!! It's a winner!!!

    Symmetrical Benchmark

    Posted by D Kozlak on May 4th 2021

    Speed: 17.9 RPM: 480 PAP: 5 7/8 RT x 2 1/4 DN No-thumb, one league per week, tournaments when I can. The Ebonite Game Breaker 4 (GB4) is a contender for THE ‘benchmark’ symmetrical ball and THS killer. Easily a “first ball out of the bag”. The Game Breaker series from Ebonite has been the brand’s most famous in recent years because of it’s performance and value. The core engineers dissected the Enhanced V2 core to recreate the physical shape and numbers, knowing that this was the root of the GB line’s success. The GB4 is a solid reactive, featuring the proven GB 12.0 veneer, ensuring the performance and success us bowlers demand from a Game Breaker branded ball. With the out of box surface at 500/1500 and the Enhanced V2 core this ball reads the mid lane and digs it’s teeth in the back end to give me a motion that’s more of a hard arc than smooth and continuous. And that’s with an all purpose layout that I chose (70x4.5x35). But don’t get me wrong, this ball has excellent continuation. This ball is an excellent option to start a shift for league and, depending on the pattern you’re rolling on, should be plenty useful late into that shift even if you need to move to a deep inside line like I do. Don’t be afraid to adjust the cover (before your USBC sanctioned event starts) with some polish/shine to get the GB4 further down lane as you’ll still be able to get that shape that you’re looking for. With the Dark Red/Red colored cover stock and Orange lettering this ball looks great sitting on the ball rack and rolling down the lane, crushing the pins. Moderately priced, the GB4 outperforms expectations and the price point. With the intent for medium/med-heavy patterns I see the GB4 excelling on heavier volume patterns and with some polish/shine can be just as useful on lighter patterns or when the pattern transitions and a solid with surface is reading too early. Be well, rip racks ...and shred pins.

    Ebonite GB4, building off a legendary nameplate!

    Posted by JAMES GOULDING on Apr 21st 2021

    Ebonite GB4 Review I drilled the Ebonite GB4 to be the big symmetric ball in my bag when other symmetrics aren’t enough through the mids, but I still wanted more length than my asymmetrics. By laying it out 3.75” x 35, I got the “flip and grip” I was looking for with tremendous performance. The GB4 handles medium-heavy volumes very well, for instance I used it Monday night and shot 725 on a THS that has not had many big scores all season in that building. It has performed exceptionally well on sport patterns, like Holman 37’ and PBA Chameleon. This will be the first ball out of my bag when I see decent volume, and it will tell me if I need to ball up to something bigger, ball down to a smoother, weaker ball, or stick with the GB4 and annihilate the competition. The GB4 is available now from Moore’s Pro Shop and pro shops everywhere. Ebonite means performance!
