Ultimate Fastener Combo Kit - 1989–1997.5 12V 5.9L Dodge Cummins

Ultimate Complete Engine Fastener Solution – Head Studs + Main Studs + Connecting Rod Bolts + Rocker Arms Combo Kit

Upgrade your engine build with the ultimate combination of strength and reliability. This premium combo kit includes head studs, main studs, rocker arms, and connecting rod bolts, providing a complete solution for securing your engine’s most critical components.

Why choose a combo kit? Pairing head studs and main studs ensures a uniform clamping force across both the top and bottom ends of the engine. Combined with high-strength connecting rod bolts, this kit helps eliminate common failure points such as head lift, blown head gaskets, and main cap walk — especially under high-boost or heavy-duty towing conditions. 

Installing head studs requires properly milled rocker arms to clear the added stud height. This set ensures everything fits perfectly, eliminating guesswork. 

Get everything you need in one kit instead of sourcing parts separately. This not only saves you money but also prevents delays and compatibility issues during installation.

Whether you’re boosting, towing, or daily driving, this all-in-one kit reduces the risk of head lift, blown head gaskets, and main cap walk – common failure points in high-performance applications.
