Get the XDP X220 Main Stud Kit XD3012MS and enhance the bottom end of your 1997.5-2002 Dodge 5.9L Diesel. This main stud kit is manufactured from high-quality 8740 Chrome Moly and incorporates a proprietary element for added strength and durability. A tensile strength between 220K psi and 236K psi and a yield strength between 210K psi and 230K psi ensures these studs can handle the increased performance of your application. In addition, the threads are rolled after heat-treating to deliver optimum fatigue strength.

Upgrading from the OEM main bolts to studs also allows you to obtain much more precise torque readings. A bolt twists as it is tightened, so it's reacting to two different forces at the same time. With a stud, the torquing force gets applied to the vertical axis, resulting in a more even clamping force. Furthermore, the studs offer easier engine assembly and proper alignment of the main bearing caps. Unlike OEM Torque-To-Yield (TTY) bolts which must be replaced after each use, these studs are reusable. These studs are manufactured in an ISO/TS 16949 quality control facility and include washers and 12-point nuts.
