RCV Performance Assembly Lubricant

RCV Performance Assembly Lubricant: Engineered for Extreme Drivetrain Demands

When you invest in high-performance CV axles, the lubricant you use at assembly isn't an afterthought — it's a critical part of the system. RCV Performance understands this better than almost any other brand in the off-road drivetrain world. As a division of Aircraft Gear Corp., a family-owned company with more than 70 years of aerospace and automotive drivetrain manufacturing experience in the United States, RCV brings the same engineering precision to their assembly lubricant as they do to their legendary axle systems.

Specially Formulated for CV Joint Applications

RCV's assembly lubricant isn't a generic grease pulled off a shelf — it's purpose-built chemistry matched to the components it protects. This is a specially formulated synthetic grease for extreme applications, and is recommended for use with all RCV CV joints. What sets it apart is its molybdenum disulfide (moly) content: RCV High Performance Synthetic Moly CV Grease is specially formulated synthetic grease for extreme applications, and contains a significant concentration of moly. Moly is a dry-film lubricant additive that provides a tenacious protective layer between metal surfaces under high-pressure, high-heat, and high-shock-load conditions — exactly the environment CV joints face during aggressive off-road use.

Matched to RCV's Product Ecosystem

RCV Performance tools and lubricants are designed to ensure proper installation and long-lasting performance of CV joints. This philosophy reflects a key differentiator: RCV doesn't just sell you an axle and send you on your way. They've developed lubricants tuned specifically for their joint geometries and tolerances, so the grease film distribution, viscosity, and additive package all work in harmony with their hardware. From desert racing to rock bouncing, RCV's specially developed grease provides the peace of mind needed to tackle any terrain.

It's also worth noting that RCV offers more than one grease formulation for different use cases. The standard Synthetic Moly CV Grease is not recommended for UTV CV joints or specific race CV joints — for those applications, RCV offers their high-temperature SPEC grease (HT1LF-SPEC). Matching the right lubricant to your specific build is part of the RCV approach to system-level performance.

Why Assembly Lubricant Matters

Even the strongest axle shaft will suffer premature wear if assembled without proper lubrication. RCV's CV designs deliver smoother power transfer, improved steering control, and consistent performance even at extreme operating angles in demanding environments — but those benefits are only fully realized when the joint is correctly packed and assembled from the start. Using RCV's own assembly lubricant removes any guesswork about compatibility and ensures the grease you're using was designed with your components in mind.
