The 503T is the newest mid-price introduction from Track. The 503T uses the same Packman magnetite core that was used to power the 503C. The cover has been changed to the solid Gen MT reactive cover that is finished at 2000 Abralon.

This rough finished ball gave us the best reaction on the heavy test pattern. At the box finish this new coverstock easily handled the amount of oil on this pattern. All three testers kept the ball at the box finish for the entire testing session and just made small two and one adjustments to catch more oil in the heads as needed.

Moving to the medium pattern, Stroker’s lower rev rate came in
