Main Stud Kit For 1989-1997 5.9L 12V Dodge Cummins

These are 14 mm main studs designed for early 1997 and older vehicles, providing better clamping force than main bolts and improving stability in high-performance applications.

• Main studs provide superior clamping force compared to main bolts, reducing wear on block threads and assisting with main cap alignment.
• Studs remain stationary during tightening, reducing the chance of main cap walking under high loads.
• They are especially beneficial in high-performance applications where increased stability and durability are required.
