Product Description
The FLEECE FPE-34772 EXHAUST MANIFOLD STUD KIT is a premium exhaust manifold hardware upgrade for 5.9L and 6.7L Cummins diesel engines. Designed with a unique 4mm Allen socket head stud configuration, this kit provides easier installation and removal while delivering improved durability and clamping performance compared to factory hardware.
Factory Cummins exhaust manifold bolts are prone to corrosion, loosening, and breakage from repeated heat cycles and exhaust expansion. The Fleece FPE-34772 kit replaces those fasteners with high-quality studs and hardware designed to help maintain manifold sealing and simplify future turbocharger or manifold service.
This kit is ideal for stock replacement, turbo upgrades, towing applications, and high-performance diesel builds where reliable exhaust manifold sealing is critical.

WHY UPGRADE EXHAUST MANIFOLD STUDS?
Exhaust manifold hardware is exposed to extreme heat cycles, vibration, and expansion that can loosen or damage factory bolts over time. Upgrading to premium stud hardware helps improve manifold retention, reduce exhaust leaks, and simplify future service on high-mileage or performance Cummins applications.
