TS Gapl. Piston Ring Set Ford 6.7L Diesel 3.898

The Total Seal Piston Ring Set for Ford 6.7L Diesel with 3.898 inch bore diameter is a precision-engineered replacement ring kit designed for Powerstroke diesel engines. This complete piston ring set delivers the sealing integrity and compression retention required for diesel engine rebuild and restoration projects, whether you're performing factory-spec maintenance or addressing wear on high-mileage units.

Specified at 3.0 mm top ring thickness, 2.0 mm second ring thickness, and 2.5 mm oil ring thickness, this kit provides the precise clearance geometry that Ford Powerstroke engineers calibrated for the 6.7L platform. Standard tension rings maintain consistent pressure against cylinder walls across the full operating temperature range of diesel combustion, critical for minimizing blowby and preserving fuel economy. The steel construction withstands the extreme pressures diesel engines generate—compression ratios typically exceeding 16:1—without ring flutter or accelerated wear.

This ring set is engineered for fleet operators, diesel technicians, and engine builders rebuilding Ford Powerstroke 6.7L units in pickup trucks, commercial vehicles, and industrial equipment. Whether addressing worn ring grooves, restoring compression after extended service, or performing a complete bottom-end refresh, proper ring specification is essential for meeting OEM performance standards and extending engine life. The 3.898 inch bore sizing ensures compatibility with factory cylinder dimensions and honing specifications.

Total Seal rings are manufactured to close tolerances suitable for professional diesel engine work. When ordering replacement rings, verify bore diameter and ring dimensions against your engine's specifications to ensure proper fit and sealing performance.
