The Story
The TSP Pro Series 04-20 LS Cylinder Head 12-Point Stud Kit is engineered for superior strength and reliability. Each fastener is crafted from 35 chromoly steel, delivering a minimum tensile strength of 190,000 PSI to withstand extreme conditions. To enhance durability, the threads are precision-rolled after heat treatment and rigorously tested for both tensile and yield strength. For long-lasting protection, all hardware is finished with a black oxide coating and an oil treatment, effectively preventing rust and corrosion. This high-performance stud kit is designed to provide exceptional clamping force, ensuring a secure and stable cylinder head installation.
