Cosworth Ultra High Performance 4B11 EVO X Head Studs
Manufacturer Part # 20043887
Here at Cosworth, it is important that we create designs that optimize engine performance and make durability, strength, and longevity our primary goals. In high performance engine builds, it is essential to have heavy duty head studs to reduce the cylinder head movement for high compression and high boost engines. These types of head studs also optimize the cylinder head to block sealing.
Our incredibly well-designed Ultra High Performance Head Studs do all that and more. We have manufactured these head studs from 625+ tool steel with a tensile strength of 260,000psi. Additionally, the head studs have been specially heat treated in a vacuum-sealed furnace and then treated in a unique nitrogen chamber that makes them as strong and tough as possible. These Head Studs also come complete with washers and nuts. They have been manufactured with a hex broach as well to make installation a great deal easier.
These genuine studs that we have created also utilize a base seating feature. This helps to evenly distribute the weight and pressure load on the stud rather than straining the threads. More often than not this base seating feature is utilized only in high-level racing engines but can be yours for any use thanks to our expert Cosworth team.
