ARP Ultra Torque Assembly Lubricant 20 oz Brush-Top Container — Controlled Application & Consistent Fastener Torque

ARP 100-9911 Ultra Torque is a high-performance assembly lubricant in a 20 oz brush-top container designed to ensure consistent, accurate fastener torque during engine and mechanical assembly.

When building engines or assembling critical mechanical joints, consistent torque readings are essential for reliability and safety. ARP formulated this lubricant to provide a uniform friction surface on threads and under bolt heads so torque values reflect clamping load rather than variable surface drag. The brush-top 20 oz container delivers controlled application and reduces waste compared with bulk dispensers.

How does ARP Ultra Torque affect torque accuracy?

Ultra Torque standardizes the friction coefficient between mating fastener surfaces so torque translates predictably into clamping force. Applying the lubricant to threads and under the bolt head minimizes erratic torque peaks caused by surface irregularities or dry metal-on-metal contact.

• Formulated for consistent friction characteristics across multiple assemblies
• Helps reduce torque scatter caused by variable surface finishes
• Improves repeatability when using torque wrenches or angle measurements

Where and how should I apply the lubricant during assembly?

Use a thin, even coat on stud threads, bolts, and under head bearings where the manufacturer specifies a lubricated fastener. The brush-top cap lets you deposit precise amounts on each fastener, avoiding excess that could contaminate nearby systems.

• Brush top for controlled application to threads and bearing surfaces
• Apply to clean, dry threads and mating surfaces for best results
• Wipe away any stray lubricant from non-fastener areas immediately

Is this product suitable for engine builds and high-stress assemblies?

ARP Ultra Torque is designed with high-performance engine and mechanical applications in mind. It helps achieve correct preload on studs and bolts used in heads, main caps, and other critical joints where accurate clamp load is required.

• Commonly used on cylinder head bolts, main studs, and clutch/drive hardware
• Compatible with typical high-stress automotive fasteners when used as directed
• Reduces the risk of under- or over-torquing that can compromise assemblies

What are the product size and package details?

The ARP 100-9911 comes in a 20 oz brush-top container sized for shop use and repeated applications. The compact package fits on a parts bench and is easy to store in a cabinet or toolbox for regular assembly work.

• 20 ounce brush-top container for controlled distribution
• Package dimensions approximately 5.29 x 2.88 x 1.55 inches
• Manufactured in the United States; part number 100-9911

Who is this for? ARP 100-9911 Ultra Torque is aimed at professional engine builders, race shops, and serious DIYers who require dependable torque readings and repeatable clamp loads. If you assemble engines, rebuild transmissions, or work on performance drivetrains where fastener preload matters, this brush-top lubricant helps standardize your results and simplifies fastener prep. It is not a substitute for following bolt manufacturers' torque procedures; always apply per your engine builder or OEM specifications.
