Ram Cummins 5.9L & 6.7L - Gator Head Studs (1998.5-2025)
Type: Head Studs
Secure your cylinder head. Support higher boost. Build with confidence. The Gator HD220 Head Stud Kit is engineered for Dodge/Ram Cummins engines that demand stronger clamping force than factory head bolts can provide. Manufactured from premium HD220 alloy and rated at 220,000 PSI tensile strength, these studs are built to handle elevated boost pressure, heavy towing, and high-horsepower applications.
Factory head bolts can stretch under high cylinder pressure, especially on tuned or hard-working Cummins engines. This heavy-duty stud kit replaces OEM hardware with precision-machined fasteners designed to maintain consistent clamping force under extreme thermal and boost conditions. Whether you're building for towing reliability or maximum performance, this upgrade reinforces the foundation of your engine.
