Maxseal Piston Ring Set 4.000 Bore 2.0 1.5 4.0mm

The Total Seal Maxseal Piston Ring Set 4.000 Bore with 2.0 x 1.5 x 4.0mm specifications is designed for serious engine builders and mechanics who require precision compression sealing and minimal blowby in high-performance or rebuilt engines. This ring set addresses a critical need: factory rings often compromise between cost and performance, leading to compression loss and increased oil consumption.

Total Seal's Maxseal line features advanced ring geometry tailored for both street and competition applications. Each ring is precision-manufactured to exacting tolerances, ensuring consistent bore contact and superior sealing throughout the engine's full stroke. The 2.0mm top ring, 1.5mm second ring, and 4.0mm oil ring configuration optimize groove pressures and ring flexibility, reducing friction while maximizing gas sealing efficiency.

Mechanics and engine rebuilders working on small-block Chevrolet, Ford, Mopar, or similar platforms will find this ring set invaluable for building engines that target improved compression ratios, reduced oil consumption, and enhanced durability. The 4.000-inch bore specification makes this set compatible with common small-block stroker builds and 4-inch overbore applications, ensuring versatility across various engine combinations.
