Purchase the XDP X220 Series Head Stud Kit XD3014HS for your 1989-1998 Dodge 5.9L Diesel 12-Valve engine. Upgrading the OEM head bolts is a must when adding horsepower and torque to your diesel-powered Dodge Ram. The OEM bolts typically can't handle the additional pressure from high-performance applications which can lead to the cylinder head lifting.
Upgrading to studs helps keep your cylinder head locked down and avoid head gasket failures. This XDP head stud kit is constructed from high-quality 8740 Chromoly Steel construction that also includes a proprietary element added for upgraded strength and durability.
The threads are rolled after heat-treating to deliver optimum fatigue strength. These studs are rated at 225K-233K psi tensile strength and 205K-215K yield strength to ensure a strong hold under higher combustion pressures.
Upgrading from head bolts to studs also allows you to obtain a much more accurate torque reading. A conventional bolt gets twisted as it is tightened, so it's reacting to two different forces at the same time. With a stud the force gets applied to the vertical axis, resulting in a more even clamping force.
Furthermore, they provide for easier engine assembly and proper alignment of the cylinder heads every time. 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. Included with the stud kit 12-point nuts and washers. Assembly lubricant sold separately.

- 10mm Studs Test Out At A Max Load: Over 120KN
- Manufactured In An ISO/TS 16949 Quality Control Factory
- Studs Are Reusable, Unlike Torque-To-Yield (TTY) Bolts Which Much Be Replaced After Each Use
Tech Tips:
- XDP Thread Cleaning Chasers (Sold Separately): The XDP Thread Cleaning Chasers XD40125TC (For Head Studs) and XD40128TC (For Rocker Arm Pedestal Bolts) are an excellent add-on that should be used prior to installation of this kit. Using Thread Cleaning Chasers ensures that you are able to properly clean the threads in your engine block before the installation and torquing of the head studs. Clean threads will provide you with accurate torque readings which are critical during your head gasket repair, or engine build.
- XDP X-TRA Slick Engine and Fastener Assembly Lubricant (Sold Separately): The use of XD541 is highly recommended during engine assembly. Apply XDP X-TRA Slick Lubricant to head studs, head bolts, main studs, main bolts, connecting rod bolts, and any other fasteners used during engine assembly. Using a proper assembly lubricant during fastener installation reduces friction and torque pre-load scatter in the torquing sequence, while also helping to prevent thread galling and seizing.
