ARP Head Studs and Chromoly Pushrods are included in all 4.5L long block engines and are a must-have upgrade for any VT-275 / LCF Powerstroke Engine. These extra heavy-duty studs are rated at 220,000 psi tensile strength and provide the clamping force required to keep your 4.5L Power Strokes cylinder heads from lifting due to higher combustion pressure. The ARP 250-4202 is our most popular head stud for your Ford and international diesel, and we use it in all of our engine packages. ARP 2000 Material - 220,000 psi tensile strength.
The factory pushrods in your 4.5L are designed for factory Boost levels and are known to cause valvetrain issues. Safeguard your engine with J&K's upgraded pushrods at no additional charge! These are revised-length pushrods built from superior materials and thicker walls for increased rigidity. By increasing the diameter of the tubing from the stock 11/32 to 3/8, the load is spread over a larger surface area without causing the pushrods to bind with the port of the cylinder head. This larger diameter pushrod will provide almost 50% more loading capacity than the stock 11/32 diameter. These Pushrods are created from Hard-drawn 4130/4135 seamless chromoly tubing, the highest quality available from mills, and initially formulated for aerospace/aircraft use. This is a high-quality pushrod that provides approximately 170,000 psi tensile strength.
Knowledge of details & differences like this makes J&K your best choice in North America. We’re the most knowledgeable choice for service, sales, and rebuilds on both the long block & short block 4.5L Powerstroke engines.
