ARP main studs

ARP main studs are a popular upgrade for engines where higher demands are placed on strength, stability and reliability than with standard fasteners. They are used to secure the main bearing caps to the engine block and are therefore an important part of the engine bottom end, where the crankshaft operates under high load. When the engine is exposed to higher cylinder pressure, more RPM and more power than standard, the quality of this fastening becomes even more important.

In this category you will find ARP main studs for engine builds, rebuilds, tuning and motorsport, where a stronger and more precise solution than standard main bearing bolts is desired. ARP is known for high material quality and precise manufacturing, which makes their main studs suitable for engines where correct preload and even clamping force are crucial for durability.

ARP main studs are often chosen for performance engines, track cars, motorsport engines and serious engine builds where better control of the fastening in the engine bottom end is desired. Strong and stable fastening around the main bearings is important to keep the engine correctly assembled under load and can be a significant part of a more durable engine build.
