Total Seal Piston Rings Advanced Profiling Ring Set Bore

Total Seal Advanced Profiling (AP) piston ring sets are engine piston rings for street, race, mild nitrous and mild forced induction engines. The line uses the same ring technology Total Seal supplies to top builders in Cup, IRL, NHRA, IHRA and Formula 1. Each part number is matched to a specific bore, so you can choose the right set for your build.

Key Features:

• Advanced Profiling ring technology: Steel rings are designed for strength and long life under extreme conditions.
• Precise tolerances: Steel allows tighter manufacturing tolerances than other ring materials.
• Low friction and weight: Thinner ring profiles reduce friction and weight.
• Improved sealing: Flatter rings help the ring seal against the cylinder wall.
• Complete ring set construction: Each set includes top, second and oil rings. The oil rings are stainless steel.
• Multiple configurations: The AP family includes sets with conventional or gapless top and second rings. The ring type depends on the series, and bore and ring thickness vary by part number.

Select the child part number that matches your engine's bore and ring groove dimensions. Total Seal AP ring sets give engine builders a high-quality sealing solution for performance and racing applications.
