ARP Pontiac Super Duty 4-Cylinder Cast Block 2-Bolt Main Stud Kit

ARP's 8740 chromoly steel main stud kit is a solid choice for reinforcing the main bearing caps on your Pontiac Super Duty 4-cylinder cast block. These studs are designed to handle the increased stress that comes with performance builds or heavy-duty use, ensuring your crankshaft stays securely in place under load.

Unlike stock bolts, these ARP studs provide a more consistent and reliable clamping force. They are manufactured with rolled threads, which are stronger and less prone to stripping than cut threads, and feature a black oxide finish for corrosion resistance. This kit is specifically for 2-bolt main blocks, offering an improved way to secure your bottom end.

When rebuilding or upgrading your Pontiac 4-cylinder, using a main stud kit like this from ARP is a smart move to prevent cap walk and maintain proper bearing alignment, especially if you're pushing the engine beyond its original specifications.
