Piston Ring Set 4.060 Bore 1.2 1.5 3.0mm

The Piston Ring Set 4.060 Bore 1.2 1.5 3.0mm by JE Pistons is designed for serious engine builders and high-performance mechanics engaged in stroker builds, turbo applications, and precision engine rebuilds. This ring set is essential for controlling combustion pressure, minimizing blow-by, and managing oil consumption in oversized or modified engines.

Featuring a three-piece configuration with a 1.2mm top ring, 1.5mm second ring, and 3.0mm oil ring, this set is precisely machined for a 4.060-inch bore diameter. The three-ring design enhances gas sealing during the compression stroke, while the wider oil ring effectively controls crankcase pressure and prevents oil from escaping during high-load conditions.

Mechanics working on big-bore 4.060-inch engines, including LS and small-block Chevy platforms, will find this ring set indispensable for achieving optimal performance. JE Pistons' reputation among drag racers and street performance enthusiasts is built on their ability to withstand extreme boost levels and high RPM environments.
