ARP Main Stud Kits | Multiple Cadillac Fitments (135-5507)

The ARP Main Stud Kit is a high-performance fastening solution designed to secure engine main caps and prevent cap walk or fretting. Crafted from 8740 chromoly steel and heat-treated in-house to achieve a 190,000 psi tensile-strength rating, these studs offer exceptional strength and durability. The precision J-form threads are rolled after heat treatment, resulting in stronger, more reliable threads compared to standard options. The kit includes hardened, parallel-ground washers and high-quality nuts, ensuring a secure and consistent fit. This product enhances engine integrity by providing a robust clamping force, making it ideal for high-performance or heavily modified engines where maintaining proper main cap alignment is critical.

Compatible with multiple Cadillac models, these ARP main stud kits are suitable for engines requiring a reliable, bolt-on upgrade. Designed to fit various Cadillac applications, they serve as a direct replacement for stock fasteners, offering increased strength and stability under demanding conditions. The installation involves replacing factory main bolts with these studs, providing a more secure and consistent clamping force during engine operation. Suitable for street, track, or racing applications, this kit is essential for engine builds that demand maximum reliability and performance. The kit ensures proper main cap retention, helping to prevent engine damage during high-stress driving scenarios.
