Piston Ring Set 3.188 Classic 1/16 5/64 5/32

The Piston Ring Set 3.188 Classic 1/16 5/64 5/32 from Total Seal is engineered for serious engine builders and mechanics who demand precision in high-performance applications. This classic race-spec ring set is designed for 4-cylinder engines with a 3.187-inch bore, delivering the tight tolerances and material quality required for forced-induction builds, naturally aspirated performance engines, and vintage race applications. Whether you're freshening a reliable daily driver or preparing a competition platform, these rings provide the compression sealing and blow-by control essential to engine longevity and power delivery.

This complete ring set combines three critical components: a 1/16-inch top ring, 5/64-inch second ring, and 5/32-inch oil-control ring, all manufactured from ductile iron with plasma-moly coating for superior wear resistance and reduced friction. The plasma-moly treatment significantly extends ring and cylinder wall life while improving cold-start performance and oil economy—critical advantages in both street and strip environments. File-fit design means these rings are ready for hand-fitting to your specific cylinder bore, ensuring optimal ring-to-wall clearance and preventing premature wear or excessive blow-by that compromises power output and oil consumption.

Mechanics and engine builders trust Total Seal rings for rebuild kits, performance overhauls, and competition applications where standard-tension rings may not provide adequate sealing under boost or high rpm loads. This set is ideal for 4-cylinder platforms including classic imports, domestics, and modern builds requiring precise 3.188-inch bore rings. Proper installation requires careful honing to the correct surface finish, precise ring gap filing, and correct groove clearances—tasks that separate professional results from amateur work. Stock your shop with this proven ring set for customer builds requiring championship-level compression sealing.
