ARP Ultra-Torque Fastener Assembly Lubricant

If you're installing a set of head studs, main studs, or our new injector hold down studs for Cummins applications, then you need to pick up a bottle of ARP Ultra-Torque to make for a perfect installation.  ARP Ultra-Torque has been specifically designed to reduce tension preload scatter and eliminate the need to cycle high performance diesel engines before final installation.  Ultra-Torque obtains 95-100% of the recommended installed preload on the first cycle, allowing the fastener to reach the proper preload on the first pull without cycling.  It also stabilizes the preload levels within 5% between a group of fasteners, ensuring that you won't have one stud with more preload than the next.
