Who Is Roto Grip?
Roto Grip is the high-performance specialist of the Storm family of brands, built in the same Brigham City, Utah plant as Storm itself. Over the years it has earned a loyal following among aggressive, rev-dominant bowlers who want strong midlane read and an angular, punishing backend. The brand is known for high-differential asymmetric cores, reactive coverstocks, and its Rotational Stability Technology (RST), the design behind some of the most talked-about balls in the sport.
Roto Grip organizes its lineup by performance tier, from the friendly HP1 Hustle line up to flagship HP5 releases, so there is a Roto Grip ball for every style and budget. BowlersMart carries the full Roto Grip catalog of balls, bags, accessories, and apparel, with pro-shop drilling expertise behind every order and free shipping on every sale.

The Roto Grip HP System, Explained
Roto Grip sorts its balls into performance tiers, HP1 through HP5. The higher the number, the stronger the core, the more aggressive the coverstock, and the more oil the ball is built to handle. Here is how the tiers break down so you can match the right ball to your game.
Hustle (HP1)
$99-$114
Newer and developing bowlers who want a smooth, controllable reactive ball for medium to drier conditions, at the most accessible Roto Grip price point
e.g. Hustle M+M, Hustle X-Ray, Hustle Earth
Ultimate Wrecker (HP2)
$104.95
Bowlers ready to step up from entry performance who want a stronger, more aggressive reactive ball that still tracks smoothly through the medium oil of a typical house shot
e.g. Ultimate Wrecker
Gremlin & Rockstar (HP3)
$139-$179
League and tournament bowlers who want strong midlane read and reliable backend motion on medium to heavier oil from Roto Grip’s high-performance tier
e.g. Gremlin, Rockstar, Rockstar Amped
RST & Attention (HP4)
$169-$174
Competitive bowlers who want upper-tier asymmetric power with Rotational Stability Technology for a strong, controllable, angular reaction on heavier patterns
Transformer (HP5)
$199.95
High-rev and tournament players who want Roto Grip’s flagship asymmetric core and strongest coverstock for the heaviest oil and the most aggressive backend
e.g. Transformer

Helpful Answers
Roto Grip Buying Guide
What do Roto Grip’s HP1 through HP5 numbers mean?
HP stands for the performance tier of the ball. HP1 is the most accessible reactive tier, built around the Hustle line for newer bowlers and drier lanes. As the number climbs, the core gets stronger, the coverstock more aggressive, and the oil capacity higher: HP2 and HP3 cover the performance and high-performance range for league play, HP4 brings upper-tier asymmetric cores and Rotational Stability Technology, and HP5 is the flagship tier for the heaviest oil and the highest rev rates. Matching the tier to your game and the lanes you bowl is the fastest way to find the right Roto Grip.
Which Roto Grip ball is right for me?
Start with your speed, rev rate, and the oil you see. Newer bowlers and those on drier house shots do well with the Hustle line (HP1). Stronger league bowlers step into the HP3 Gremlin and Rockstar balls for more midlane and backend, while competitive players who want angular asymmetric motion reach for the HP4 RST and Attention balls. High-rev and tournament players who attack heavy oil want the flagship HP5 Transformer. Our pro-shop staff can pair any Roto Grip ball with a layout that fits your style.
What is RST, Rotational Stability Technology?
RST is a Roto Grip core design philosophy aimed at giving the ball a stable, predictable, and repeatable reaction at the breakpoint. It pairs a strong asymmetric core with coverstock tuning so the ball stores energy through the front and midlane, then releases it in a controlled, angular motion off the spot. You will see RST featured in Roto Grip’s HP4 releases like the RST Hyperdrive.
Are Roto Grip and Storm the same company?
They are part of the same family and are made in the same Brigham City, Utah facility, but they are run as distinct brands with their own identities and ball lines. Roto Grip tends to lean toward stronger, more aggressive, rev-friendly motion, while Storm spans the full range under its own naming. Many bowlers carry both brands in the same bag for different looks on the lane.
Does BowlersMart ship Roto Grip balls for free?
Yes. Every order at BowlersMart ships free with no minimum purchase and no hidden fees, and it comes with a 60-day no-hassle return policy. Roto Grip orders also earn Striking Rewards points you can put toward future gear.
