Construction & Design
ARP manufactures this main stud kit from premium-grade alloy steel, carefully heat-treated to achieve optimal tensile strength and fatigue resistance. Each stud is precision-machined to exacting tolerances, ensuring a perfect fit and consistent clamping force across all main caps. The studs feature a proprietary coating that protects against corrosion and galling, extending service life even in harsh operating environments.
The design focuses on replacing the factory main bolts with studs that allow for more uniform load distribution and easier maintenance. This approach reduces the chance of thread damage in the engine block and improves overall bottom-end durability.

What does the ETA date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
