Description You won't lose horsepower due to blowby when you install a set Total Seal gapless piston rings. The secret is in Total Seal's gapless second ring technology. This arrangement uses an oversize cast-iron main ring, plus a chrome-faced secondary ring that overlaps the main ring's end gap. This interlocking design forms a gapless seal, which gives Total Seal rings a miniscule leakdown rate of just 2 percent or less, compared to the 8 to 10 percent rate for conventional gapped rings. Perfect for street or race applications. No special tools or modifications are required for the installation of Total Seal Rings. We stock the Total Seals rings in a variety of sizes, Click here to view all sizes.
