What is the difference between ARP2000, L19 and CA625+?
ARP2000 suits most high-performance builds. L19 offers higher strength but is sensitive to handling and corrosion. CA625+ is used for extreme cylinder pressure or rpm.
Why is ARP lubricant important?
ARP torque values assume Ultra-Torque lubricant on threads and under the head. Without it, clamp load becomes unpredictable.
What are the torque specifications for the ARP VR38 Main Stud Kit?
The ARP VR38 Main Stud Kit should be torqued according to ARP's specifications, which typically recommend around 80 ft-lb for the main studs when using ARP Ultra-Torque lubricant. Always refer to the latest ARP instructions for the most accurate torque values.
Do I need to machine the main caps when installing the ARP VR38 Main Stud Kit?
Yes, it's advisable to check the main caps for alignment and ensure they are properly line-bored after installation of the ARP VR38 Main Studs. This helps maintain proper clearances and ensures the longevity of the engine under high-performance conditions.
Can I use the ARP VR38 Main Stud Kit with a stroked VR38DETT engine?
Yes, the ARP VR38 Main Stud Kit is suitable for both standard and stroked VR38DETT engines. The superior strength of the ARP 2000 material makes it ideal for high-performance applications, including those with increased displacement.
What is the benefit of using hardened parallel washers with the ARP VR38 Main Stud Kit?
The hardened parallel washers included in the ARP VR38 Main Stud Kit ensure even load distribution across the main caps, which helps achieve accurate torque readings and reduces the risk of warping or failure under high-stress conditions.
Is the ARP VR38 Main Stud Kit compatible with OEM main caps?
Yes, the ARP VR38 Main Stud Kit is designed to work with OEM main caps. However, it's essential to verify that the main caps are in good condition and properly aligned to ensure optimal performance and reliability.
