Piston Ring Set 4.135 Clsic Gold 1.5 1.5 3.0mm

The Piston Ring Set 4.135 Classic Gold by TOTAL SEAL is a precision engine component engineered for high-performance and classic automotive applications. Built for enthusiasts and professional rebuilds alike, this ring set addresses the critical need for reliable compression sealing and oil control in 4.135-inch bore engines. Whether you're restoring a vintage engine or upgrading an existing platform, proper piston ring selection is foundational to durability, fuel efficiency, and overall engine longevity.

Constructed with TOTAL SEAL's Classic Gold coating, this piston ring set features a three-ring configuration: two 1.5mm compression rings and a 3.0mm oil control ring. The Classic Gold finish provides superior break-in characteristics and reduces friction against cylinder walls, translating to faster ring seat-in and improved blowby control during initial operation. The 4.135-inch bore sizing ensures precise fitment and optimal sealing geometry, while the multi-piece design allows each ring to function independently, managing combustion pressure and preventing excessive oil consumption.

This ring set is ideal for engine builders, machine shops, and serious automotive restorers working with classic or performance engines in the 4.135-inch bore range. Proper installation requires careful attention to ring gap specification and bore conditioning—cylinder honing to the correct finish and diameter is critical to ring performance and engine reliability. Compatibility verification with your specific engine block and piston assembly is essential before purchase; consult technical specifications or a qualified machine shop if you're uncertain about fitment for your particular build.
