Innovative AEBS dimple head and main stud fasteners utilize neutralizer ends, which are used in IRL, F1 racing engines. The dimple design preloads all the threads of the studs on all the threads on the block. The dimple bottoms out first rather than bottoming out the thread of the stud. Our studs are also 5 percent bigger than the competitions. This translates into a precise torque spec on head and main studs. Ultimately it provides better holding of the cylinder head to the block and of the main caps to the block.
