The Fleece Performance Upper Gasket Set (FPE-CUMM-0718-UPR-GS-NHG) provides a comprehensive top-end sealing solution for 2007.5–2018 6.7L Cummins engines. When dropping in a new long block or performing major top-end maintenance, standard practice requires replacing every single disturbed seal to prevent high-pressure fluid leaks and costly re-work. This factory-style component kit eliminates the guesswork of sourcing individual seals, ensuring your engine rebuild maintains optimal compression and fluid containment from the very first start.
By consolidating every necessary component into a single, high-quality package, Fleece Performance ensures your assembly process remains seamless and efficient. Utilizing premium materials that meet or exceed original equipment standards ensures that your engine can withstand the extreme thermal cycles and high boost pressures typical of the 6.7L Cummins platform. Investing in a dedicated, comprehensive gasket set guarantees a proper, reliable seal, protecting both your new long block and your time.
