Main Cap Studs & Hardware
Main cap studs hold the main bearing caps to the engine block. Those caps keep the crankshaft located in its bore. Factory main bolts work well in many stock engines. Builders often switch to studs when they add boost, raise rpm or rebuild a bottom end for harder use. A stud threads into the block and stays put while the nut is tightened. This tends to give more even clamping force and less wear on the block threads each time the caps come off.
Right now we have 1 product in stock in this category, from ARP. It is the ARP Vauxhaul/Opel Main Stud, sold as one stud. Check how many your engine needs before you order.
Confirm the thread size and length match your block and caps.
Decide whether you need single studs or a complete set for your engine.
Follow the maker's torque and lubricant instructions exactly.
Have a machine shop check the main bores after changing fasteners, since clamping load can affect bore shape.
Use the vehicle selector to pick your vehicle to see what fits.
