A fifth wheel plate takes serious abuse. Every turn, every bump, and every mile of towing puts pressure on the steel where your kingpin rides. The right grease cuts the groan, stops metal-on-metal wear, and keeps the plate from drying out between trips. The wrong grease either flings off in the first hundred miles or turns into a gummy mess that traps grit and grinds your hitch down faster.

We looked at the lubricants truckers, RVers, and heavy-haul drivers actually trust on their fifth wheel and pintle plates. Some are old-school lithium grease in a tub, some are slick poly fifth wheel pucks, and a couple are heavy-duty moly formulas built for extreme pressure. Below are the seven we rank highest, what each one does best, and where each one falls short so you can match the grease to how you tow.

1. Lucas Oil X-Tra Heavy Duty Grease: Best Overall

Lucas Oil X-Tra Heavy Duty Grease

🛒  Check Price on Amazon →

Lucas X-Tra Heavy Duty earns our top spot because it nails the one thing a fifth wheel plate grease has to do, which is stay where you put it. This is a tacky lithium complex grease that grabs onto the steel plate and does not sling off when you get up to highway speed. On a loaded fifth wheel that runs hot and flexes through every turn, that staying power translates directly into less wear and a much quieter hitch. Drivers who fight constant groaning over the kingpin usually notice it drop off after the first proper application.

The trade-off is that the same tackiness that makes it cling also makes it a magnet for grit if your rig sits outside between trips, and the red dye gets on everything. It is not a clean grease to work with. But for actual performance under load, in heat, and in wet weather, it is hard to beat, and a single tube doubles as a solid chassis and wheel bearing grease, which is why it is the one we reach for first.

  • Heavy tack keeps it clinging to the plate instead of flinging off on the highway
  • High dropping point handles the heat that builds up under a loaded fifth wheel
  • Strong water resistance so rain and road spray do not wash it away

Pros: Stays put on vertical and angled plate surfaces; Quiets hitch groan noticeably on the first hookup; Works as a general chassis grease too, so one tube covers more than the plate
Cons: The red dye stains clothes and skin and is stubborn to clean up; Tacky body picks up dust and grit if you store the trailer uncovered for long stretches

2. Mopar Fifth Wheel Plate Lubricant: Best for Heavy Towing

Mopar Fifth Wheel Plate Lubricant

🛒  Check Price on Amazon →

Mopar’s fifth wheel plate lubricant is one of the few greases on this list built from the start for the plate rather than borrowed from the chassis aisle. That focus shows when you are pulling something genuinely heavy. The extreme pressure package is tuned for the concentrated load a kingpin puts on a small patch of steel, and it resists being squeezed out from between the plate and the trailer the way lighter greases can be. For heavy gooseneck and large fifth wheel rigs, that protection is the whole point.

The downsides are practical rather than performance related. Stock can be inconsistent depending on where you buy, so you may not always find it on the shelf, and the thicker body is harder to work into the plate when it is cold out. Warm it up a little or apply it on a mild day and it spreads fine. If you tow at or near your rig’s limits, the purpose-built formula is worth the small hassle.

  • Formulated specifically for fifth wheel and slider plates, not a repurposed chassis grease
  • Extreme pressure additives protect against the high point loads at the kingpin
  • Holds up under the weight of large gooseneck and fifth wheel trailers

Pros: Designed for exactly this job, so coverage and cling are dialed in; Excellent protection under heavy and sustained loads; Trusted on factory tow packages from a major manufacturer
Cons: Availability comes and goes depending on the seller; Heavier consistency takes more effort to spread evenly in cold weather

3. Timken Premium All-Purpose Grease: Best Extreme Pressure

Timken Premium All-Purpose Grease

🛒  Check Price on Amazon →

Timken is a name truckers know from wheel bearings, and that pedigree carries straight over to the fifth wheel plate. This is an extreme pressure lithium complex grease engineered to carry serious load without breaking down, which is exactly the demand a kingpin places on the plate. The texture is smooth and even, so it spreads into a clean film rather than clumping, and the high dropping point means it does not run off when the hitch gets hot on a long grade.

Where it gives a little ground is tack. It is not as sticky as the Lucas or a dedicated plate puck, so on a rig that sits in the rain it can need refreshing a touch sooner. Treat it as a slightly more frequent reapplication and you get bearing-grade protection on your plate plus a grease that covers your trailer hubs at the same time. For drivers who care most about load capacity and brand trust, it is an easy pick.

  • Extreme pressure formula from a respected bearing manufacturer
  • High dropping point resists thinning out when the plate heats up
  • Smooth, consistent texture that spreads evenly across the plate

Pros: Outstanding load-carrying ability for the kingpin contact area; Comes from a brand that lives and breathes bearing science; Doubles as a top-tier wheel bearing grease for the trailer
Cons: Less aggressively tacky than dedicated fifth wheel greases, so reapply on schedule; Sold mostly in tubes, which is fine for the plate but burns through fast on big jobs

4. Reese Pro Series Fifth Wheel Lube Plate: Best Mess-Free

Reese Pro Series Fifth Wheel Lube Plate

🛒  Check Price on Amazon →

If your least favorite part of fifth wheel ownership is the black grease ring on everything you own, the Reese lube plate is the answer. Instead of smearing grease across the plate, you drop this hard poly disc over the kingpin so it rides between the trailer and your hitch plate. It carries the load and slides cleanly, which kills the groan and the wear without a single fingerprint of grease. For RVers who hook and unhook often, the convenience is genuinely hard to overstate.

The catch is fit and seating. It is sized for standard kingpin and plate dimensions, so you need to confirm it matches your hitch before counting on it, and if it is not seated squarely over the kingpin it can shift or work loose during a hookup. Get the right size and seat it properly and it just works, trip after trip, with zero cleanup. It is the pick for anyone who values a clean truck bed as much as a quiet hitch.

  • Hard poly disc replaces grease entirely for a clean hookup
  • Drops over the kingpin and rides between the plate and trailer
  • Eliminates the black grease ring on your truck bed and clothes

Pros: Completely mess-free, no grease to spread or clean up; Cuts hitch friction and noise without any product flinging off; Reusable and easy to drop in or pull out as needed
Cons: Fits standard kingpin and plate setups only, so check your hitch first; Can shift or pop out if not seated correctly on the kingpin

5. Valvoline Crimson Multi-Vehicle Grease: Best Water Resistance

Valvoline Crimson Multi-Vehicle Grease

🛒  Check Price on Amazon →

Valvoline Crimson is the one to grab if your fifth wheel lives where it rains, snows with road salt, or sees coastal air. The calcium sulfonate complex base laughs off water in a way ordinary lithium grease cannot, so it stays on the plate and keeps protecting instead of washing into a thin smear. Just as important, its corrosion package guards the bare steel of the plate against rust and pitting, which is what actually chews up a hitch over the years in wet climates.

It is a touch stiffer than a red lithium grease when temperatures drop, so cold-weather application takes a little more muscle, and as a premium formula it is not the most casual choice for someone who just wants a quick smear. But for drivers in wet or salty environments, the water and corrosion resistance pays off every season, and the same tin handles boat trailer bearings beautifully. It is a specialist that earns its spot.

  • Calcium sulfonate base shrugs off water far better than basic lithium grease
  • Strong corrosion protection for plates exposed to rain, salt, and road spray
  • Holds its body and cling even after repeated water contact

Pros: Best in this group for wet and coastal conditions; Excellent rust protection keeps the plate from pitting; Adaptable enough for trailer bearings, especially boat trailers
Cons: Premium calcium sulfonate formula is pricier in spirit than basic grease; Slightly stiffer body than red lithium grease in cold weather

6. Lucas Oil Red N Tacky Grease: Best Value Tub

Lucas Oil Red N Tacky Grease

🛒  Check Price on Amazon →

Red N Tacky is the workhorse a lot of drivers already have in the shop, and it does double duty on the fifth wheel plate without complaint. As the name promises, it is genuinely tacky, so it grabs the plate and stays through highway speeds and hard cornering. The texture is smooth and fiberless, which means it pumps cleanly through a grease gun and spreads into an even film by hand just as easily. For the volume you get, it is one of the strongest value plays here.

It shares the family trait of being messy. The bright red dye gets on hands, clothes, and the truck bed, and the same cling that keeps it on the plate also collects dust and grit if the trailer sits out in the open. None of that hurts how it performs, it just means you keep a rag handy. If you want proven cling and a tub that lasts across the plate, the chassis, and the bearings, this is a smart everyday choice.

  • Very high tack so it clings hard to the plate under speed and load
  • Smooth, fiberless texture pumps easily through a grease gun
  • Large sizes give plenty of product for the plate and the rest of the rig

Pros: Excellent cling for the money it represents in value; Easy to apply by hand or grease gun; Big tubs last a long time across many applications
Cons: Bright red color stains and is messy to handle; Tackiness collects dirt on rigs left parked outdoors

7. Super Lube Synthetic Grease with PTFE: Best Synthetic

Super Lube Synthetic Grease with PTFE

🛒  Check Price on Amazon →

Super Lube is the clean-hands choice. This synthetic grease is loaded with PTFE, the same slick compound used in nonstick coatings, and that gives the plate a notably low-friction film that hushes the hitch quickly. Just as appealing for a lot of owners, it is translucent rather than dyed, so it does not leave the black or red mess that lithium greases do. The synthetic base also holds its consistency across a wide temperature range, staying workable on cold mornings and stable on hot mountain pulls.

What you give up is tack. It is simply not as sticky as a Lucas or a purpose-built plate grease, so under sustained high-speed towing it can migrate and want refreshing sooner. It also tends to come in smaller containers, which suits dressing the plate more than greasing an entire rig. For owners who prize a clean, slick, low-mess film and do not mind reapplying a bit more often, the synthetic PTFE formula is a genuinely pleasant way to keep the plate happy.

  • PTFE micro-particles add slickness that quiets the plate fast
  • Clean translucent formula that does not stain like red lithium grease
  • Wide operating temperature range from cold mornings to hot grades

Pros: Far cleaner to handle than dyed lithium greases; PTFE gives an extra-slick, low-friction film; Stable across a broad temperature spread
Cons: Lower tack than dedicated fifth wheel greases, so it can need more frequent reapplication; Smaller container sizes mean it suits the plate more than a whole rig

Frequently Asked Questions

How often should I grease my fifth wheel plate?

A good rule is to inspect and refresh the grease on your fifth wheel plate every three months or roughly every three thousand miles of towing, whichever comes first. If you tow heavy, drive in rain and road salt, or hear groaning over the kingpin, check it more often. The grease should look like a continuous film, not a dried-out smear or a gritty crust. Wipe off the old, contaminated grease before adding fresh, because piling new grease on top of old grit just grinds the plate down faster.

Can I use regular wheel bearing grease on a fifth wheel plate?

You can, and many drivers do, as long as it is a quality NLGI 2 lithium or lithium complex grease with good tack and water resistance. Several picks here, like the Timken and Lucas options, are excellent as both bearing and plate grease. The key qualities for a plate are cling so it does not fling off at speed, a high dropping point so it survives heat, and water resistance so rain does not wash it away. A cheap, low-tack grease will work loose quickly, so choose a heavy-duty formula rather than the bargain tub.

What is a fifth wheel lube plate and is it better than grease?

A lube plate, like the Reese poly disc on our list, is a hard slick disc that drops over the kingpin and rides between your hitch plate and the trailer. It carries the load and slides cleanly without any grease at all, which means no black ring on your truck bed and nothing to clean off your hands. It is not necessarily better at protecting the steel than a top grease, but it is far cleaner and more convenient, especially if you hook and unhook often. Just confirm it fits your kingpin and plate dimensions before relying on it.

Why does my fifth wheel hitch groan or creak when turning?

That groan is almost always dry metal-on-metal contact between the kingpin plate and the trailer, or between moving parts of the hitch head. It means the grease has worn thin, washed off, or dried out and is no longer separating the surfaces. Clean the plate, apply a fresh, tacky grease across the full contact area, and the noise usually disappears on the next hookup. If a good greasing does not quiet it, inspect the hitch head pivot and jaws, because worn or under-lubricated moving parts inside the head can groan too.

Does the color of fifth wheel grease matter?

The color itself does not affect performance. The bright red of greases like Lucas Red N Tacky is just dye, and a translucent synthetic like Super Lube performs its job without any dye at all. What matters is the formula underneath, meaning the thickener type, the tack, the dropping point, and the water and extreme pressure additives. Color can be handy for spotting coverage on the plate or telling products apart in the shop, but never choose a grease by color alone. Read the spec, not the shade.

Our Verdict

For most drivers, the Lucas Oil X-Tra Heavy Duty Grease is the best all-around choice for a fifth wheel plate. It clings hard, quiets the hitch fast, shrugs off heat and water, and one tube doubles as chassis and bearing grease. If you tow near your rig’s limits, the Mopar Fifth Wheel Plate Lubricant is the standout runner up, built specifically for the plate with an extreme pressure package tuned for the kingpin’s heavy point load. And if your priority is a clean truck bed over everything, the Reese lube plate skips grease entirely and still kills the groan.
