Why Upgrade to a Complete ARP Kit?
Because your engine doesn’t care how much you spent on parts if the hardware holding it together is garbage.
The ARP 534-9502 kit gives you a matched set of fasteners, ensuring uniform clamping force across your entire engine—no weak links, no mismatched hardware, no surprises later.
It’s easy to assemble a show-quality engine when you use ARP’s handy Engine & Accessory Fastener Kit. Virtually the whole lot you wish to have comes completely organized in one convenient package (no wish to take care of twelve different part numbers)

Why It Matters
Using old or low-quality hardware can lead to:
- Uneven clamping force

The stainless steel is polished to succeed in a brilliant luster, and provides a distinctive, maintenance-free environment.Each and every kit has a dozen different type fasteners, all neatly organized and labeled in protective vacuum-wrapped packages. Both materials are nominally rated at 170,000 psi tensile strength and come in both hex and 12-point heads. Please note that these kits are designed for carbureted engines.
