Shop with Blessed Performance for the XDP X220 Series Head Stud Kit for your 1998.5-2023 Dodge Ram 5.9L/6.7L Cummins diesel. In addition to the upgraded strength, replacing the head bolts with studs also allows you to obtain a more precise torque reading. A bolt gets twisted as it is tightened, so it's reacting to two different forces at the same time. With a head stud the force gets applied to the vertical axis, resulting in a more even clamping force. Studs can also ensure proper alignment of the cylinder heads every time and provide for easier engine assembly. Unlike the OEM Torque-To-Yield (TTY) bolts which must be replaced after each use, these studs are reusable which makes them a must have for high-performance applications. These studs are manufactured in an ISO/TS 16949 quality control facility. Kit includes 12-point nuts, washers, and installation instructions. Assembly lubricant sold separately.
