Technical Specifications and Design Features
The E-651K piston ring set is tailored for Ford vehicles requiring a 4.1100 inch bore diameter, including the E-350 Club Wagon, Excursion, and F-350 Super Duty models. The top ring’s keystone face design helps maintain a tight seal under varying operating conditions, while the steel with molybdenum material enhances wear resistance. The second ring’s reverse torsional face and grey iron composition provide effective secondary sealing and durability. The 2-piece conformatic oil ring design ensures efficient oil control and reduces oil consumption, critical for heavy-duty engine performance.

Installation Notes and Tips
Installation of the Sealed Power E-651K piston ring set requires careful attention to ring orientation and proper groove clearance. Ensure the cylinder bore is clean and within specification before installation. The rings are standard size and do not require file fitting. Use appropriate ring compressors and follow manufacturer torque specifications for piston installation. Proper lubrication during assembly is recommended to prevent initial wear.

The E-651K set is made from high-grade materials designed to withstand heavy-duty engine conditions.
