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 at a 220,000 PSI tensile 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. Included with the stud kit are 12-point nuts and washers. 

Features:

• 220K PSI Tensile Strength
• Threads Rolled After Heat Treating
• Will Not Stretch Like The Factory Studs
• 10mm Studs Test Out At A Max Load: Over 120KN
• High-Strength 8740 Chromoly Steel Construction With Added Proprietary Element
• Studs Are Reusable, Unlike Torque-To-Yield (TTY) Bolts Which Much Be Replaced After Each Use
• Includes Washers & 12-Point Nuts

TECH TIPS:
XDP Thread Cleaning Chasers (Sold Separately):
The XDP Thread Cleaning Chasers XD40125TC (For Head Studs) & 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.

Fastener Assembly Lubricant (Sold Separately):
The use of assembly lubricant is highly recommended during engine assembly. Apply 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.
