About Permatex
Permatex has manufactured chemical solutions for vehicle assembly and repair for over a century — thread lockers, gasket makers and sealants that show up in nearly every V-twin service procedure.
Permatex engine assembly lube is a specialized lubricant formulated for V-twin motorcycle engines. It's designed to be applied to bearing surfaces and metal mating surfaces before the initial start-up of new or rebuilt motors. This critical step ensures components are protected, preventing scuffing and galling during the crucial break-in period of your Harley-Davidson or Indian Motorcycle engine.

This ensures a smoother, healthier break-in and contributes to the longevity of your motor.
