ARP 100-9909 Ultra Torque Assembly Lubricant

Updated June 8, 2026

ARP 100-9909 Ultra Torque Assembly Lubricant is a premium moly-based fastener lubricant designed for high-performance engine assembly. It ensures consistent and repeatable torque readings by minimizing tension pre-load scatter, which occurs when using oils or other lubricants. This 1.69 oz squeeze tube lubricant is formulated to be used on all engine fasteners, including bolts and studs, to achieve proper preload without requiring multiple torque cycles.

How It Works

Ultra-Torque lubricant reduces frictional inconsistencies that cause tension pre-load scatter. By providing a stable coefficient of friction, it allows the installer to achieve the required bolt stretch or preload in a single torque application, eliminating the need to cycle fasteners multiple times. The moly-based formula also prevents rust and corrosion during the life of the lubricant.

Key Features

This assembly lubricant is specifically designed for high-performance engine fasteners. It offers consistent clamping force, reduces the risk of under- or over-torquing, and is compatible with ARP and other quality bolts. The squeeze tube packaging allows easy, precise application directly onto threads and under bolt heads.

Application Notes

Apply Ultra-Torque liberally to threads and under the bolt head before installation. For best results, use on all critical engine fasteners such as connecting rod bolts, main cap bolts, cylinder head bolts, and studs. It is suitable for both steel and aluminum components. No additional lubricant or anti-seize compound is needed. Torque to manufacturer specifications in one smooth, continuous motion.

Because of frictional inconsistencies with oil, moly, and other lubricants it takes multiple cycles of torquing the bolt, loosening it, and tightening it again to obtain the required preload or stretch.

Engine Cooling Components

Because of frictional inconsistencies with oil, moly, and other lubricants, it takes multiple cycles of torquing the bolt, loosening it, and tightening it again to obtain the required preload or stretch. Typically, when a fastener is first tightened, friction is at its highest point and the preload value or stretch is low. As the fastener is cycled numerous times the friction decreases and the preload increases. This phenomenon is called "preload scatter." With ARP Ultra Torque assembly lubricant, a fastener need only be torqued once to get within 5 percent of ideal preload, and it remains consistent through all subsequent cycles (from race-prep machining through final assembly). Moreover, given the inconsistencies of ordinary lubes, it's quite possible for adjacent head bolts or studs.

Frequently asked questions

AI-generated content

Can this lubricant be used on head bolts and connecting rod bolts?

Yes, ARP Ultra-Torque is formulated for all high-performance engine fasteners, including head bolts, main cap bolts, connecting rod bolts, and studs.

Is Ultra-Torque compatible with ARP fasteners only?

It is designed to work optimally with ARP fasteners but can be used with any quality bolts and studs where reduced pre-load scatter and accurate torque are required.

Does this lubricant need to be reapplied if the bolt is loosened and re-torqued?

If a fastener is loosened, clean off the old lubricant and reapply a fresh coat of Ultra-Torque before re-torquing to ensure consistent friction and preload.
