KDD 7.3 Powerstroke Main Girdle

Kill Devil Diesel’s 7.3L Powerstroke Main Girdle is built for serious strength and durability where it counts — the bottom end. Precision-machined in the USA from high-grade steel, this girdle ties the main caps together to drastically reduce main cap walk and flex, a common failure point in high-horsepower or heavy-duty builds.

Whether you're pushing big power or just want peace of mind in your engine’s long-term reliability, the KDD main girdle adds critical reinforcement to keep the rotating assembly stable under stress. Designed to work with factory-style oil pans and most aftermarket setups, this is essential insurance for any performance 7.3 build.

If you're building a 7.3 to last — and to win — don’t skip the bottom-end protection that only a premium main girdle can provide.
