ARP 100-9911 Ultra-Torque Assembly Lube 20 oz Bottle

ARP 100-9911 Ultra-Torque Assembly Lube is the correct fastener lubricant to use when installing ARP bolts and studs to ARP’s recommended torque specs. If you are assembling cylinder head bolts, main studs, rod bolts, intake bolts, flywheel bolts, balancer bolts or other high-performance engine fasteners, do not guess with engine oil, moly paste or whatever mystery grease is sitting on the bench.

This is the 20 oz / 590 ml bottle with brush-in-cap, making it a practical workshop-size option for engine builders, machine shops and serious home engine assembly.

Why Use ARP Ultra-Torque?

Torque specs are only useful when the lubricant matches the fastener instructions. Different oils and lubes can change the friction between the threads, washer and nut face, which can change the actual clamp load even when the torque wrench reads the same.

ARP Ultra-Torque is designed to reduce preload scatter and give more repeatable fastener tension during engine assembly. That matters on critical engine parts like cylinder heads, main caps and connecting rods, where clamp load affects sealing, bearing housing shape, bore distortion and long-term reliability.

Put simply: if the ARP instructions call for ARP Ultra-Torque, use ARP Ultra-Torque. Saving a few dollars on the wrong lube is not clever when the engine is worth thousands.

General ARP engine fastener assembly

Always follow the torque specs and lubricant instructions supplied with the ARP fastener kit being installed.

Important Fitment Note

Do not assume all torque specs are the same with every lubricant. ARP torque values are often based on using ARP Ultra-Torque, and changing lubricant can change the actual clamp load. Check the ARP instructions for your specific fastener kit before final assembly.
