The Piston Ring Set 4.040 Gapless 2nd 1/16 1/16 3/16 from TOTAL SEAL is designed for serious engine builders and high-performance mechanics who require precision ring control and minimal blow-by. This set is specifically engineered for 4.040-inch bore applications, making it an excellent choice for racing engines and forced induction builds.
The gapless top ring set eliminates compression loss and power leakage that standard gapped rings allow. TOTAL SEAL's innovative gapless ring design features a unique butt-joint configuration that closes under combustion pressure, preventing hot gases from escaping past the ring end-gap. This design is particularly effective in high-RPM environments and cylinder pressures beyond 12:1 compression.
Engine builders working with stroker kits, big-bore blocks, or competition applications will benefit most from this precision ring set. The balanced ring pack, featuring a second ring thickness of 1/16-inch and a 3/16-inch oil ring, effectively controls oil consumption while maintaining low friction and rapid response to pressure changes.
