Bore Range 4.125"-4.185"
TS1 Race Ring Sets are designed for more demanding race engines and require file fitting.

As normal ring wears, the gap opens up allowing more combustion pressures to escape (blow-by). The Total Seal Gapless ring solves this problem. Its patented design incorporates a two part-interlocking ring to close off the gap and provide a better or improved seal between piston and cylinder As the total seal ring wear, the gap stays sealed, even after dozens of grueling races.
