ARP Ultra Torque Assembly Lubricant 20 oz. Brush-Top — Consistent Torque, Anti-Galling Protection

ARP 100-9911 Ultra Torque is a high-performance assembly lubricant supplied in a 20 oz. brush-top container to reduce friction and protect fasteners during torqueing and assembly.

This formula is engineered for precision bolting tasks where consistent torque values, reduced galling and long-term corrosion protection matter. Packaged in a convenient brush-top 20 oz. container, the lubricant makes it simple to apply an even film to threads, washers and bearing surfaces before final assembly. The product is made in the United States and supplied under ARP part number 100-9911, with compact shipping dimensions that suit shop and garage storage.

How does Ultra Torque improve torque accuracy?

Applying a dedicated assembly lubricant like Ultra Torque produces a controlled, repeatable friction coefficient between mating surfaces. That stability helps torque wrenches deliver more accurate clamping forces and reduces the variability common when using dry or improvised lubricants.

• Consistent friction characteristics for repeatable torque readings
• Thin, uniform film prevents over- or under-torquing
• Brush-top applicator enables precise placement on threads and under heads

What surfaces and hardware is this lubricant meant for?

Ultra Torque is formulated for metal-to-metal assembly tasks, particularly fasteners such as bolts, studs and nuts found in engines, drivetrains and structural joints. It’s suitable for threaded fasteners, tapered seats and under-head interfaces where controlled torque and protection against seizing are needed.

• Threads and studs — ensures smooth startup torque
• Washers and bearing surfaces — reduces fretting and galling
• High-heat engine assemblies and drivetrain components

How do I apply the 20 oz. brush-top container for best results?

The brush-top design lets you spread a thin, even coat on fastener threads and contact faces before installation. Wipe any excess, assemble the parts, and torque to the specified value using your standard procedure — the lubricant will help stabilize readings without affecting the hardware geometry.

• Use brush to coat full thread length and underside of bolt heads
• Remove heavy buildup — aim for a light, even layer only
• Follow manufacturer torque specs; adjust if torque tables assume lubricated threads

What are the container and shipping details I should know?

The product ships in a compact 20 oz. brush-top bottle that is easy to store on a bench or in a parts cabinet. Package dimensions and weight make it convenient for single-hand use in busy shops and for inclusion with service kits or build carts.

• Package dimensions: 5.29 L x 1.55 H x 2.88 W inches
• Package weight: 2 pounds — light and transportable
• Part number: 100-9911; country of origin: United States

Who is this for: ARP 100-9911 Ultra Torque Assembly Lubricant is aimed at professional mechanics, engine builders, race shops and serious home enthusiasts who require predictable torque results and protection against galling during assembly. If you assemble engines, head studs, suspension components or any bolted joints where torque accuracy and fastener longevity matter, this brush-top 20 oz. bottle is designed to make application quick, clean and repeatable.
