Piston Ring Set 4.030 Claimer 1/16 1/16 3/16

The Piston Ring Set 4.030 Claimer 1/16 1/16 3/16 from Total Seal is purpose-built for serious engine builders and mechanics tackling performance rebuilds on eight-cylinder engines. These drop-in rings are engineered for engines bored to 4.030-inch specifications, delivering reliable compression and oil control without requiring custom machine work. Whether you're freshening a stock engine or preparing a budget-conscious build, this claimer-style ring set offers a time-proven solution that performs consistently across a range of driving conditions.

Each ring combines ductile iron construction with moly-enhanced facing to reduce friction and extend ring life, while the gapless second ring design minimizes blow-by and stabilizes oil film on cylinder walls. The 1/16-inch top ring thickness and 1/16-inch second ring thickness paired with the 3/16-inch oil ring thickness create a low-tension profile that reduces parasitic drag—critical for maximizing horsepower in competitive or street applications. Total Seal's precision manufacturing ensures consistent gap clearance and ring-to-groove fit, eliminating the need for custom piston work and allowing bolt-in installation that saves labor time and cost.

This eight-cylinder piston ring kit is ideal for mechanics rebuilding engines in muscle cars, street rods, or vintage performance builds where budget and reliability must coexist. The claimer designation indicates these rings are drop-in compatible with standard pistons in the 4.030-inch bore range, making them a practical choice for roadside repairs and customer builds alike. Installation is straightforward—use a ring compressor and follow standard ring gap procedures—making this set accessible for both professional shops and experienced home builders seeking quality without premium pricing.
