The PR5167400-16 kit also includes a set of 7.400-inch chromoly pushrods. These pushrods are designed to be an exact replacement for the original OEM components, ensuring a direct and seamless fit. The chromoly material used in the construction of the pushrods provides superior strength and resistance to bending and fatigue, making them ideal for high-performance applications.

It is important to note that this kit is intended for use in racing applications and high-performance street use. Installation of these components may require modification to the engine and may result in increased noise, vibration, and potential for increased emissions. It is recommended that this kit be installed by a professional mechanic or race engine builder.

In summary, the AMS Racing PR5167400-16 Hardened Trunion Kit is an essential upgrade for Ford Modular engines seeking improved power and durability. The set includes four hardened trunion rocker arms and four 7.400-inch chromoly pushrods, all manufactured from high-strength materials to ensure superior rigidity, resistance to fatigue, and resistance to wear. This kit is suitable for use with 4.8L, 5.3L, 5.7L, and 6.0L engines and is ideal for racers, hot rodders, and enthusiasts seeking high-performance applications.
