ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
The Cummins 4BT is a legendary engine known for its durability, but when you start adding performance modifications, the factory head bolts can become a weak point. This Auto Racing Products (ARP) Head Stud Kit is designed to provide the necessary clamping force to keep your 4BT cylinder head sealed under increased boost and cylinder pressures. Manufactured from high-tensile 8740 chromoly steel, these studs are built to withstand the rigors of performance diesel applications.
Using studs instead of bolts provides a more consistent clamping force across the head, which is vital for maintaining a perfect seal in high-output engines. The 12-point nut design allows for easier installation and torque application, even in the tight confines of a 4BT engine bay. Each kit includes the necessary hardened washers to ensure even load distribution, protecting your cylinder head from stress concentrations. Whether you are performing a 4BT swap or modifying an existing engine for more power, this ARP kit is a critical component for long-term engine reliability. Find all your essential engine fastener needs at GGCRACING.
