- Brand: ARP
- Part Number: ARP-203-5409
- Country of Manufacture: United States
ARP main stud kits are designed to help prevent main cap walk and fretting while protecting the threads in your engine block. Studs also make it easier to achieve accurate torque readings since they don’t twist into the block, keeping clamping force on a single axis. Reduced stress on block threads can contribute to improved block life—especially important for aluminum blocks—and helps with repeatable main cap alignment during assembly.
