Piston Ring Set 4.010 Bore 1.2 1.5 3.0mm

The Piston Ring Set 4.010 Bore 1.2 1.5 3.0mm from JE Pistons is designed for engine builders and performance mechanics who require precise ring geometry and quality materials. This set is essential for sealing combustion pressure, controlling oil consumption, and maintaining optimal ring-to-bore clearance in various engine applications.

Featuring ring thicknesses of 1.2mm, 1.5mm, and 3.0mm, this piston ring set balances compression sealing with minimal friction and weight. The 4.010-inch bore specification ensures a precise fit in engine blocks that require this diameter, which is crucial for effective blowby control and reducing oil vapor escape into the crankcase.

Ideal for small-block and mid-sized displacement engines, this piston ring set is suitable for both naturally aspirated and forced-induction builds. Proper installation requires careful attention to ring end-gap positioning and bore preparation to ensure longevity and optimal performance.
