Clean Length and a Skid-Flip Backend
About the Kinetic Sapphire Ice
The Track Kinetic Sapphire Ice is a clean, length-first pearl for medium oil. It pairs the Shuttle Core with the Prime Response Pearl (HK22) coverstock at a polished finish, so it gets down the lane easily and then flips off the friction with a quick, angular backend. It is the skid-and-flip piece of the Track line.
The Kinetic Sapphire Ice is built for length and a sharp downlane move. The Shuttle core has a lower differential, so it stores energy rather than flaring early, while the polished HK22 pearl conserves that energy through the heads. The result is a clean, controllable ball that saves its reaction for the back of the lane, ideal for medium oil and for players who want length with a defined flip.
Understanding the Track Shuttle Core and Track Prime Response Pearl (HK22)
Track built the Kinetic Sapphire Ice for clean length and a skid-flip backend on medium oil. Specifically, the Shuttle Core posts a 2.48 RG, a .040 differential, and a low .006 intermediate differential, numbers that store energy for length and a quick, angular move down lane, while the Prime Response Pearl HK22 cover at a polished finish keeps the ball clean through the fronts. As a result, it gives you a skid-flip reaction on medium oil. The per-weight specifications are listed below.
A Lower-Differential Core Built to Store Energy
At the heart of the Kinetic Sapphire Ice is the Shuttle Core. At 15 lb it measures a 2.48 RG, a .040 differential, and a low .006 intermediate differential, numbers that produce lower flare and store energy for the back of the lane. Rather than flaring early, the Shuttle core holds its energy so the ball can make a quick, angular move at the breakpoint.
Track wraps the Shuttle core in DynamiCore, Brunswick’s industry-leading outer-core technology, for added durability and a stronger hitting ball. That energy-storing design is what gives the Kinetic Sapphire Ice its skid-flip personality: clean through the fronts, sharp off the friction.
A Polished HK22 Pearl for Maximum Length
The Kinetic Sapphire Ice wraps that core in Track’s Prime Response Pearl (HK22) coverstock at a polished finish. The pearl additive and polished surface let the ball conserve energy and clear the front of the lane easily, so it gets down the lane and then flips off the friction with a quick, defined backend.
That clean read and skid-flip backend make the Kinetic Sapphire Ice a great fit for medium oil and for players who want length and a sharp downlane move. Leave it polished for maximum length and flip, or take the surface down at your pro shop for an earlier, smoother read when the oil increases.

BowlersMart Tips: Where the Kinetic Sapphire Ice Fits in Your Track Arsenal
Where It Fits in Your Arsenal
In the Track lineup, the Kinetic Sapphire Ice is the clean, skid-flip pearl. It stores more energy and reads later than the stronger Synthesis, Paragon, and Theorem pieces, so it is the ball you move to when the lane dries and you need length with a sharp backend. Pair it as the length option at the back of your bag.
Surface Adjustments
The polished finish gives the Kinetic Sapphire Ice its clean length and skid-flip backend. Take the surface down with a lower-grit pad for an earlier, smoother read on more oil, or keep it polished for maximum length and flip when the lanes dry. Have surface changes done at your pro shop for an even, consistent finish.
Coverstock Care
Wipe the HK22 pearl cover with an approved reactive ball cleaner after every session, and deep clean it periodically. Keeping the cover fresh preserves the clean length and sharp backend that define the Kinetic Sapphire Ice.
