I-Core Gen4 Power for Medium to Heavy Oil

About the Synthesis

The Track Synthesis is the strongest, most aggressive piece in Track's current lineup. It introduces the fourth generation of the legendary I-Core, the asymmetric I-Core Gen4, paired with the QR-12 Solid (HK22C) coverstock. The result is a ball that grips the midlane, builds momentum, and finishes with strong, continuous motion on medium to heavy oil.

The Synthesis takes the proven I-Core and pushes it further. The Gen4 version adds intermediate differential for a sharper, more angular breakpoint than previous I-Cores, and the QR-12 Solid cover at a sanded finish reads the midlane with confidence. With the most flare in the line, the Synthesis is the answer when you need the most hook and the strongest backend.

Understanding the Track I-Core Gen4 and Track QR-12 Solid (HK22C)

Track built the Synthesis for aggressive, high-flare motion on medium to heavy oil. Specifically, the asymmetric I-Core Gen4 posts a 2.48 RG, a strong .053 differential, and a high .020 intermediate differential, numbers that produce 5 to 6 inches of track flare and a sharp, angular breakpoint, while the QR-12 Solid HK22C cover at a 1500-grit Siaair finish reads the midlane and builds momentum. As a result, it gives you the strongest hook and continuation in the line. The per-weight specifications are listed below.

The Fourth Generation of Track's Legendary I-Core

At the heart of the Synthesis is the asymmetric I-Core Gen4. At 15 lb it measures a 2.48 RG, a strong .053 differential, and a high .020 intermediate differential, a combination that produces 5 to 6 inches of track flare and a sharp, angular breakpoint. The increased intermediate differential is what separates Gen4 from earlier I-Cores: it adds a more pronounced, continuous move at the spot.

Track wraps the I-Core Gen4 in DynamiCore, Brunswick's industry-leading outer-core technology, for added durability and a stronger hitting ball. Because the core is asymmetric, layout has a strong influence on the reaction, so your pro shop can tune the pin and intermediate differential to control how early and how angular the Synthesis plays.

An HK22C Solid That Reads the Midlane With Confidence

The Synthesis wraps that core in Track's QR-12 Solid (HK22C) coverstock at a 1500-grit Siaair finish. The QR-12 solid reads the midlane with confidence and builds momentum through the pattern, so the ball grips medium to heavy oil and keeps driving rather than rolling out.

Paired with the high-flare I-Core Gen4, the QR-12 Solid gives the Synthesis its identity: a strong, aggressive ball that grips the midlane and finishes with continuation. The 1500-grit Siaair finish adds a touch more length than a typical sanded solid. Leave it at the box finish for medium to heavy oil, take the surface lower for even more traction, or polish it up for more length as the lanes transition.
