ARP Assembly Lube, also known as Ultra-Torque engine assembly lubricant,  ensures that engine fasteners will get within 5 percent of preload after just one torque application. This range has also been shown to remain consistent through to final assembly - unlike the preload scatter encountered with other lubricants. This eliminates the need to cycle high-performance engine fasteners before final installation. 

• Obtains 95-100% of recommended installed preload on first cycle
• Maintains installed preload within 5% on all subsequent cycles
• Stabilizes preload levels within 5% between a group of fasteners
• Prevents seizing and galling on threaded fasteners
• 360 °F melting point
• Metal-free
