Piston Ring Set 4.030 Moly 1.2 1.2 3.0mm

The Piston Ring Set 4.030 Moly 1.2 1.2 3.0mm by JE PISTONS is designed for high-performance engine builds, catering to builders and mechanics who require precision and durability in their engine components. This ring set is ideal for applications with a 4.030-inch bore, commonly found in stroker, turbo, and naturally aspirated performance engines. Proper selection of piston rings is crucial for optimal oil control, compression retention, and longevity.

Featuring molybdenum-coated compression rings with a thickness of 1.2mm for both the top and second rings, along with a 3.0mm oil control ring, this set balances friction and sealing performance effectively. The moly coating enhances durability by reducing wear and improving cold-start oil flow. This configuration is particularly beneficial for custom-bore specifications, ensuring compatibility where OEM rings may not fit.

Engine builders and mechanics will find this piston ring set advantageous for various applications, including race motors and modified classics. It is essential to verify bore dimensions and measure ring gaps according to the specific cylinder wall finish planned for assembly. With JE PISTONS' commitment to quality control, users can expect consistent performance and reliability from each ring in the set.
