Description

Upgrade the durability and performance of your 1998.5–2023 Dodge Ram 2500/3500 with the 5.9L or 6.7L Cummins by installing the XDP X220 Series Head Stud Kit (XD3010HS). When increasing horsepower and torque, the factory head bolts often can’t handle the added cylinder pressure, leading to cylinder head lift and head gasket failure.

The XDP Head Studs are engineered to solve this issue, providing the strength and reliability needed for high-performance builds. Manufactured from premium 8740 Chromoly Steel with a proprietary additive, these studs deliver exceptional durability and will not stretch like OEM bolts.

Precision Engineering: Rolled threads after heat-treating ensure maximum fatigue strength.
Premium Materials: Made from 8740 Chromoly Steel with a proprietary element for superior durability.
Extreme Strength: 205,000+ psi yield strength, 225,000+ psi tensile strength.
Complete Kit: Includes studs, washers, and 12-point nuts. Each stud tested at loads exceeding 120kN.
Certified Quality: Produced in an ISO/TS 16949 certified facility.
Reusable: Unlike OEM TTY (Torque-To-Yield) bolts, these studs can be reused in future engine work.

Beyond their strength, head studs provide more accurate torque readings by eliminating bolt twist, resulting in even clamping force, proper cylinder head alignment, and easier assembly.

Recommended Installation Tools (Sold Separately):

XDP Thread Cleaning Chasers (XD40125TC): Prepares block threads for optimal stud engagement.
XDP X-TRA Slick Engine & Fastener Assembly Lubricant (XD541): Reduces friction and prevents galling during installation.

Whether you’re repairing a head gasket or building a high-horsepower Cummins, the XDP X220 Series Head Stud Kit delivers the strength and dependability your engine demands.
