Ultimate Complete Engine Fastener Solution

Head Studs + Main Studs + Connecting Rod Bolts + Rocker Arms + Valve Covers Combo Kit

Upgrade your engine build with a complete, purpose-matched system designed to reinforce every major clamping point from top to bottom. This premium combo kit includes head studs, main studs, connecting rod bolts, rocker arms, and valve covers, delivering a true all-in-one solution for strength, fitment, and reliability.

Why run a complete combo kit?

Combining head studs and main studs ensures more consistent clamping force across both the cylinder head and main caps. When paired with high-strength connecting rod bolts, this kit helps address common failure points such as head lift, blown head gaskets, and main cap walk—especially in boosted, high-load, or heavy-towing applications.

Engineered fitment from top to bottom

Head stud installations often require additional rocker arm clearance due to increased stud height. This kit includes properly milled rocker arms to ensure correct geometry and clearance.

To complete the top-end upgrade, the included valve covers are designed to properly clear the upgraded valvetrain while providing a clean, durable seal and finished engine-bay appearance.

One kit. No compromises.

Sourcing these components individually can lead to fitment issues, delays, and unnecessary cost. This combo kit eliminates guesswork by providing matched components that are designed to work together, saving time and money during installation.

Whether you’re boosting, towing, or daily driving, this all-in-one engine fastener and top-end solution delivers confidence, durability, and long-term reliability—everything you need in one box.

For the 5.9L 12-valve Cummins configuration. CP114 rod bolts require angled rod caps and do not fit straight-cap rods. MP878 is the M14 main-stud kit for 1989–early 1997. Confirm the main-bearing-cap fastener configuration before ordering. Includes rocker-arm pedestals, not moving rocker arms. Not for 24-valve 5.9L or 6.7L engines.

Match each component.

The milled pedestal relief creates space beside the head-stud position while the shaft supports the rocker arrangement.

Separate sealing and fastening roles.

Each VC100 perimeter gasket seals a cover to the head; an O-ring seals each mounting bolt opening.

Follow the component procedure.

Prepare the mating surfaces and threads, and follow the instructions for each component. Do not apply one torque value or sequence to the entire bundle.
