XDP XD3014HS X220 SERIES HEAD STUD KIT FOR 89-98 DODGE RAM WITH CUMMINS ENGINE

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.

Included with the stud kit 12-point nuts and washers. Assembly lubricant sold separately.

• Thread Has Been Rolled After Heat Treatment
• High-Strength 8740 Chromoly Steel Construction
• 10mm Studs Test Out At A Max Load: Over 120KN
• 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) & 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 & 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.

The XDP XD3014HS X220 Series Head Stud Kit is an essential upgrade for 1989-1998 Dodge Ram owners with a Cummins 5.9L Diesel 12-Valve engine. This high-performance head stud kit is specifically designed to address the limitations of OEM head bolts, particularly when enhancing horsepower and torque. As your engine’s output increases, so does the pressure on the cylinder head, making your factory bolts prone to failure. The XDP stud kit locks the cylinder head down effectively, minimizing the risk of head gasket failures.

Crafted from premium 8740 Chromoly Steel, this kit boasts exceptional strength and durability. Each stud is engineered to withstand tensile strengths of 225K-233K psi and yield strengths of 205K-215K psi, ensuring that they hold up under high combustion pressures. Unlike conventional bolts, which can twist during tightening, these studs provide a consistent clamping force, resulting in more precise torque readings.

Installation of the XDP head stud kit also simplifies engine assembly by offering better alignment for cylinder heads. These reusable studs eliminate the need for replacing Torque-To-Yield (TTY) bolts after each use, making them both economical and practical. The kit includes everything needed for installation, such as high-quality 12-point nuts and washers.

For optimal performance, pairing this kit with XDP Thread Cleaning Chasers and XDP X-TRA Slick Engine & Fastener Assembly Lubricant (both sold separately) is highly recommended. These additional products ensure clean threads and reduced friction during assembly, enhancing the overall reliability and effectiveness of your engine setup. Transform your Dodge Ram’s performance with the XDP XD3014HS X220 Series Head Stud Kit, and enjoy the durability and strength necessary for high-output diesel applications.
