Red Line Assembly Lube is a specialized pre-lubrication compound engineered for V-twin motorcycle engines, providing critical protection to wear surfaces before oil pressure builds during initial startup. It offers superior film strength compared to conventional assembly greases and is designed not to clog engine filters after the first start.
For any serious V-twin engine build or rebuild, protecting internal components during the first moments of operation is paramount. Red Line Assembly Lube creates a robust, high-film-strength barrier on critical parts like camshafts, lifters, piston skirts, and bearings. This ensures that these surfaces are well-lubricated and protected from wear before your engine's oiling system can establish full pressure, making it an indispensable product for Harley-Davidson and Indian Motorcycle builders.
The 12 oz size of Red Line Assembly Lube is ideal for more extensive engine projects or for shops that frequently perform V-twin rebuilds. By preventing dry starts and initial wear, it contributes significantly to the longevity and reliability of your newly assembled engine. Trust Red Line to provide the peace of mind that comes from knowing your engine's most vulnerable components are protected from the very first turn of the key.
When should I use assembly lube vs. regular oil?
Assembly lube is applied to critical engine surfaces before startup to protect them during the crucial first moments before oil pressure builds. Use it during engine assembly or rebuild, then fill with regular engine oil.
Will this assembly lube clog my oil filter?
No, Red Line Assembly Lube is specifically formulated to disperse into the engine oil without plugging filters after the initial engine start-up.
What engine components benefit most from assembly lube?
Critical wear surfaces such as camshafts, lifters, pushrods, piston skirts, main and rod bearings, and bolt threads should be coated for maximum protection during assembly.

I haven’t used it yet, but they asked me for a review a couple of days after receiving it so here it goes: the bottle is extraordinarily cylindrical!
So different from my Torco and permatex assembly lubes. New lube was really thin and milky looking, didn't use!
