ARP Vauxhall/Opel 2.0L 16V Main Stud Kit

If you're rebuilding the bottom end of your Vauxhall/Opel 2.0L 16V engine, using a main stud kit is a smart move. These ARP main studs replace the factory bolts, offering a more secure and consistent clamping force on your crankshaft main caps. This is crucial for maintaining proper bearing alignment and preventing cap walk under stress, especially in performance applications.

ARP is well-known for making strong engine hardware, and these main studs are no exception. They're made from ARP's proprietary 8740 chromoly steel, which is heat-treated to achieve a tensile strength of 200,000 psi. This means they can handle the increased loads and pressures that come with a performance rebuild. The kit includes the necessary studs, nuts, and washers, all manufactured to tight tolerances so they fit right and perform reliably. You'll want to follow ARP's recommended torque-to-yield procedure when installing these for optimal results.
