Upgrade Your Manifold Hardware With Confidence

If you’ve ever fought with factory studs during a manifold swap, you already know how frustrating that can be. The Fleece Performance Exhaust Manifold Stud Kit is built to make that job smoother, stronger, and cleaner from start to finish. These stainless steel studs aren’t just a nice-looking upgrade, they deliver serious clamping power that helps keep your manifold sealed tight, mile after mile. Thanks to their 7mm external hex heads, installation is quick and easy, especially when you’re working in tight engine bays. This kit also includes 12-point nuts and washers for a secure fit you can count on, even under heavy boost or extreme heat. Whether you're installing an aftermarket manifold on your 5.9L or 6.7L Cummins, or just replacing tired hardware on your Ram 2500 or 3500, this stud kit gives you peace of mind and long-term reliability. It's the kind of upgrade that saves time now and prevents headaches later, all while adding a clean, high-quality look to your build.

Built For Strength Where It Matters Most

The Fleece FPE-34771 stud kit is precision engineered for durability and high-temperature performance. Manufactured from aged 603 stainless steel, these studs are designed to resist rust, corrosion, and fatigue far better than factory hardware. The improved metallurgy allows for higher torque, up to 40 ft-lbs when using anti-seize, providing stronger clamping force between the exhaust manifold and cylinder head. This added strength helps reduce the chances of warping, leaks, or hardware failure under extreme load or prolonged heat cycles. The 7mm external hex head design also makes these studs much easier to install or remove with standard tools, especially in tight or awkward locations. Designed for a wide range of Cummins applications, this kit fits 5.9L 12V engines from 1994 to 1998 with aftermarket manifolds, and 24V engines from 1998.5 to 2018, including the 6.7L, with minor installation notes like heat shield removal. Each kit comes complete with matching 12-point nuts and washers to ensure a secure, even hold across all mounting points.
