Prolube 5th Wheel Lube STAYS SLICK. Prolube 5th Wheel Lube ensures smooth movement between the trailer apron of the semi-trailer and the fifth wheel by conditioning the metal of the 5th wheel plate with our specially formulated metal conditioner.


Evenly spread and apply Prolube 5th Wheel Lube across trailer plate with the provided brush.

Clean the 5th wheel:
Pressure wash to remove hardened grease above and below the top plate. Detail-clean with a putty knife or brush if desired, being careful not to damage moving parts. For extreme build-up, you may need to remove the top plate and clean the surface and channels with a solvent. Prolube recommends fully degreasing every three months or 30,000 miles.

Apply grease:

Using a Prolube 5th Wheel Lube, apply an even amount of product across the trailer plate and spread it evenly across the surface with the provided brush.


Prolube 5th Wheel Lube is a red lithium-based grease that is blended with our specially formulated metal conditioner.

    Works good

    This sticks way better than the other greases I've used on the 5th wheel on my semi will definitely buy more when needed I don't need to add it nearly as much as the others

    Best 5th wheel lube hands down

    Best lube hands down if you try it you won't be disappointed! I put it on a truck 3 weeks ago and unhooked the trailer for the first time today and it still looks like when I first applied it.
