What drivers say about XOTIC PERFORMANCE™
Ultimate Fastener Combo Kit - 1989–1997.5 12V 5.9L Dodge Cummins with Valve Covers
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.
