ARP 4552101 Stainless 300 12-Point Intake Manifold Bolt Kit - For Ford Big Block 429/460 (385 Series)

Building or resealing a Ford big block (429 or 460ci, 385 series)? Don't use cheap hardware on your intake manifold. These ARP bolts are the gold standard. Made from their special \Stainless 300\ alloy, they're seriously strong (rated at 170,000 PSI – way stronger than Grade 8) and totally rust and corrosion-proof. The compact 12-point heads are great for tight spaces, and they come with washers for even load distribution on the gasket. The threads are precision-rolled, which means they torque down more consistently and are less likely to gall or seize. This kit (part #4552101) has everything you need to seal that intake manifold up right, preventing leaks and ensuring optimal performance. ARP makes everything in-house in the USA with insane quality control – these are the bolts the pros use. Whether you're doing a full rebuild or just fixing a pesky leak, this is the kit you want. Quality you can feel when you install it.
