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 bottom end of your 6.6L Duramax LBZ or LMM engine is subjected to massive amounts of stress, especially in high-horsepower builds. The ARP 230-5402 Main Stud Kit is designed to provide the stability and clamping force required to keep your crankshaft secure. By replacing factory main bolts with these high-strength studs, you effectively minimize main cap walk and ensure the longevity of your engine's rotating assembly.
When building a high-performance diesel engine, the bottom end is the foundation of your success. Using ARP main studs is a standard practice for professional engine builders to prevent catastrophic failure during high-load scenarios. This kit provides the necessary hardware to ensure your main caps stay seated, allowing your engine to handle increased power with confidence. Whether you are building for the track or the street, these studs are an essential component for any serious Duramax build. Find all your high-performance engine hardware needs at GGCRACING, where we prioritize quality and performance for your vehicle.
