Piston Ring Set 3.552 Classic 1.5 1.5 3.0mm

The Total Seal Piston Ring Set 3.552 Classic 1.5 1.5 3.0mm is a file-fit ring kit engineered for 8-cylinder engines requiring precision compression and oil control. This classic steel design with advanced profiling delivers consistent sealing performance in both naturally aspirated and modified powerplants, making it the choice for engine builders and machine shops prioritizing proven reliability over cutting-edge complexity.

The 3.552-inch bore diameter accommodates mid-sized V8 applications, while the 1.5mm top ring, 1.5mm second ring, and 3.0mm oil ring specification represents Total Seal's time-tested ring geometry. Standard tension provides balanced blowby control without excessive friction, a critical trade-off in high-revving engines where ring drag directly impacts parasitic loss. Steel construction in natural finish offers excellent durability and resists thermal cycling common in performance builds. File-fit rings require honing verification and ring gap setting during installation—this is standard procedure for serious engine work and ensures optimal sealing without ring stiction.

This ring set is specified for classic muscle cars, street performance engines, and naturally aspirated racing platforms where conservative ring design and proven materials outweigh exotic coatings. File-fit rings are preferred when bore preparation can be verified and controlled, and when the builder wants to dial in exact ring gap clearance for the specific application. Whether restoring a vintage big-block or building a period-correct high-performance engine, Total Seal's classic ring design delivers the sealing integrity and longevity expected in serious engine assembly.
