Build Your Engine To Handle Serious Power

If you're planning to push your 5.9L Cummins well beyond stock limits, sealing that head properly becomes more than just important, it becomes critical. The ATS Fire Ring Parts Kit gives you the extra layer of confidence you need when tuning for high boost and serious torque. Designed for diesel enthusiasts who aren't afraid to turn things up, this kit helps prevent blown head gaskets and reduces the risk of head lift under extreme pressure. It’s the kind of upgrade you want in place before you hit the dyno or head out with a heavy load behind you. It includes both the gasket and fire rings, so you’re getting the essentials to reinforce your setup right out of the box. Just keep in mind that this isn’t a bolt-on mod, it does require machining, but the results speak for themselves. If you’re building a truck that’s made to work hard and pull harder, this kit gives your engine the strength to keep up.

A Proven Solution For High Cylinder Pressure Builds

The ATS 103-910-2272 Fire Ring Parts Kit is engineered specifically for the 5.9L common rail Cummins engines found in 2003–2007 RAM 2500 and 3500 models. This kit is built to handle the increased combustion pressures often seen in modified diesel applications where performance and reliability must go hand in hand. It includes a precision head gasket along with machined fire rings that seat into the head for a superior seal between the block and cylinder head. The fire ring system works by concentrating the clamping force around each cylinder, which significantly reduces the chances of head gasket failure under high boost. While installation does require machine work on the cylinder head, this step is necessary to achieve the tight seal that high-performance engines demand. This is not a universal solution, but a purpose-built kit for serious Cummins builds that are expected to perform under load. Whether you're prepping for competition, heavy towing, or just want to make sure your engine holds strong, this kit adds a critical line of defense where it matters most.
