Piston Ring Set 4.085 1.5 1.5 3.0mm

The Piston Ring Set 4.085 1.5 1.5 3.0mm from MAHLE PISTONS is designed for builders and mechanics who require precision-fit compression and oil control in high-performance or rebuild applications. This ring set is crucial for refreshing an engine block, whether for stock restoration, street performance, or competition builds where ring blow-by and oil consumption can significantly affect reliability and power output.

The ring geometry features a 1.5mm top ring thickness, a 1.5mm second ring thickness, and a 3.0mm oil control ring, which effectively balances compression sealing with oil management and thermal expansion characteristics. MAHLE's manufacturing tolerances ensure consistent bore contact pressure and minimize blow-by, while the material composition and heat treatment provide resistance to scuffing, micro-welding, and thermal fatigue that often affect inferior aftermarket alternatives.

Professionals involved in custom short-block assemblies, vintage engine restorations, or full-bore rebuilds will appreciate the fitment accuracy and long-term durability this ring set offers. The 4.085 bore diameter accommodates a specific piston size commonly found in small-block engines, making it an ideal choice for those looking to enhance performance without compromising on quality.
