Finding the right amp research power step lubricant is the difference between a smooth, silent operation and that annoying grinding sound every time you open your truck door. If you've spent the money on a set of AMP Research PowerSteps, you already know they're one of the coolest and most functional upgrades you can add to a rig. But because they hang out right under the rocker panels, they're constantly getting blasted by mud, road salt, rain, and dust. Without a little bit of maintenance, those moving parts are eventually going to get grumpy.
It's tempting to just grab whatever can of spray is sitting on the workbench and go to town, but that's usually where things go south. Using the wrong stuff can actually make things worse by attracting even more grit. If you want those steps to last the life of your truck, you've got to be a little strategic about how you lube them up.
Why Your Steps Are Sticking in the First Place
The design of these power steps is actually pretty clever. They use a motorized linkage system that tucks the step up tight against the body when you're driving and drops it down when a door opens. The problem is that the "elbows" of that linkage—the pivot points—are completely exposed to the elements.
Over time, road grime finds its way into those tiny gaps. If you live somewhere where they salt the roads in the winter, it's even worse. That salt creates a crusty buildup that acts like sandpaper every time the step moves. Eventually, the friction becomes too much for the motor to handle, and you'll notice the steps moving slowly, stopping halfway, or just refusing to budge altogether. That's usually your cue that it's time for some amp research power step lubricant to save the day.
The Best Types of Lubricant to Use
This is where a lot of guys get it wrong. You might think a heavy-duty grease would be the best choice because it stays put, but that's actually the last thing you want to use. Thick grease is like a magnet for dirt. Once you drive down a gravel road, that grease turns into a grinding paste that will wear out your bushings faster than you can say "warranty."
Silicone-Based Sprays
Most pros and long-time owners swear by a high-quality silicone spray. Silicone is great because it provides plenty of slickness without being "sticky." It dries relatively quickly and doesn't attract nearly as much dust as a wet oil or grease would. It's also generally safe for the various plastics and rubbers that might be near the linkage.
Dry Film Lubricants
Another excellent option for your amp research power step lubricant is a dry film lubricant, often containing PTFE (Teflon). These go on wet but dry into a solid, slippery film. Since there's no wet residue left behind, dust and sand just fall right off instead of sticking to the pivot points. If you live in a particularly dusty or sandy environment, this is probably your best bet.
What to Avoid
Stay away from the standard WD-40 (the original blue and yellow can). While it's great for loosening a stuck bolt, it's actually a solvent, not a long-term lubricant. It'll make the steps move for a day or two, but it evaporates quickly and leaves the metal even more prone to rust than before. Also, avoid anything labeled as "white lithium grease" or "chassis grease" for this specific application. It's just too messy and heavy.
How to Properly Clean and Lube Your Steps
You can't just spray lubricant over a layer of dried mud and expect it to work. You'll just be trapping the dirt inside the joints. If you want to do this right, you've got to start with a clean slate.
Step 1: The Deep Clean
Grab a pressure washer or just a garden hose with a decent nozzle. Extend the steps (you can usually do this by keeping the door open or using the override switch if you have one) and blast out those pivot points. You might be surprised at how much sand and gunk comes flying out of there. If they're really nasty, use a soft-bristle brush and some mild soapy water to get into the nooks and crannies.
Step 2: Let Everything Dry
Don't spray your amp research power step lubricant onto wet metal. Water will prevent the lubricant from sticking properly, especially if you're using a dry film type. Give it some time to air dry, or if you're in a hurry, use an air compressor to blow the water out of the joints.
Step 3: Targeted Application
You don't need to soak the entire assembly. Focus specifically on the pins and the areas where the linkage arms move against each other. Give each pivot point a good shot of spray. While the lubricant is still fresh, cycle the steps a few times—open and close the door repeatedly—to help the fluid work its way deep into the bushings.
Step 4: Wipe Away the Excess
Once you've worked the lubricant in, take a clean rag and wipe off any drips or excess spray. You only need the lubricant inside the joints. Anything sitting on the outside of the metal is just going to catch dust and make your truck look messy.
Winter Maintenance is a Different Beast
If you live in the "Salt Belt," you need to be way more proactive. Road salt is the absolute enemy of moving metal parts. During the winter, it's a good idea to spray down your steps with fresh water every time you wash your truck—maybe even more often if the roads are particularly slushy.
In freezing temperatures, moisture can get into those joints and freeze solid, preventing the steps from deploying. A good coat of amp research power step lubricant actually helps displace that moisture, acting as a barrier so the ice can't get a foothold. Some guys even do a quick "maintenance spray" once a month during the winter just to keep things moving.
When Lubricant Isn't the Fix
Sometimes, you can spray all the lubricant in the world on those steps and they still won't move right. If you've cleaned them thoroughly and lubricated the pivot points, but they're still sluggish, it might be time to look at other culprits.
Check your ground wires first. These steps pull a decent amount of current, and a corroded ground can cause the motor to struggle. Also, take a look at the actual step board itself. If it's taken a hit on a rock or a curb, the linkage might be slightly bent. Even a tiny misalignment creates enough friction to overpower the motor's safety shut-off.
Keeping a Schedule
You don't have to obsess over this, but adding it to your regular maintenance routine makes a huge difference. Every time you change your oil, or maybe every other time you wash the truck, just give the steps a quick look. If they're starting to look dry or you hear a faint squeak, grab your amp research power step lubricant and spend five minutes giving them some attention.
It's one of those things that's easy to forget because the steps are "out of sight, out of mind" most of the time. But the moment they stop working and you have to hop into a lifted truck without a step, you'll wish you'd spent those five minutes with a spray can. Treat the hardware right, keep the pivot points clean, and those AMP steps will keep tucking away perfectly for years to come.
