Stackers Blocks and Chock

Stackers with Chock

Stackers leveling blocks can be stacked directly on top of each other for supporting a trailer tongue, or you can stagger the blocks to create a ramp. Not only do the individual raised squares interlock with those on the block placed above it, but the built-in handles also interlock with these squares for a more sturdy and streamlined design. The Stackers chock (A10-0922 - sold separately) can then be attached to the leveling blocks to help stop your trailer or RV from rolling off the Stackers.

Use these leveling blocks constantly- they are under the trailer now. When you use something for what it’s built for and never look back or really think about it after you reach for it .... well there’s your sign. Would buy again and again.

Liked them so much we bought more
Melissa - 11/16/2021


They work really well at the rear of the RV because of the duel wheels, but we had to use them at the front on one occasion. My RV is a freight liner Columbia Renegade Toterhome and it might be a bit to heavy for the blocks. We were at the racetrack as so we are parked on asphalt. It was very hot which could be partially to blame for crushing them slightly. I plan on getting a second set to double up at the front and try to distribute the weight better. Other than that they work great.

Your motorhome may be over the weight capacity of these leveling blocks. The blocks are safe up to a 40,000 Gross Vehicle Weight.
-- Etrailer Expert Victoria B - 10/15/2019
the second set I got seems to be stronger and will support the weight of my truck better. I think the heat was what heart the blocks before, track temp was 152F. They have been working great this season.
Denny - 10/04/2020


Works as expected/intended. Not quite big enough for a single block or stack of blocks to fit under the foot of my stabilizer jacks. Have to put two blocks side by side, so account for that in your estimate of how many you'll need. Have since cut some 18" 2X4's to use as a base under these, so if the ground is sandy/muddy the plastic blocks can't sink into the muck. Works like a charm.
Comes with a little velcro strip to bind the stack together.

A year later, still working fine. With respect to my previous comment about the stabilizer feet, I find that by angling the blocks I can get them to extend to the end of the stabilizer feet, and have had no issues doing this for the past year. 2X4s under the blocks provide a stable base. Keeping the bottom of the plastic blocks out of the sandgravel is a must if you want them to stack, otherwise, the weight of the trailer forces gravel into the spaces in the blocks. They also flex and warp under the tires unless you have a solid base e.g., wood under them. Eventually, they seem to straighten back out, but stacking isnt always smooth right after use under a wheel. We use them all the time, including in the driveway. Way easier than having an assortment of wood blocking. Some blocks are starting to fade from sunlight exposure, but so far, no failures. Will probably buy more in the future.
Douglas - 09/05/2019


These appear to be well made and will be a good alternative to the wooden blocks that I was previously using. They are lighter weight than the wooden blocks; always a concern to not haul unnecessary weight.


great product works like a charm


I have a beast that weights a ton. Bought one of these locally and found it to be almost to indestructible. It's nice to have extras in the unit besides the 2x10's I use. These things are great and very portable. Thanks for an easy transaction and speedy (and free) shipping.


Product just arrived in good shape. Nothing broken. Used all 10 under my trailer jack 4 correct height & no cracking yet. Jack pressure about 500lbs. I picked these because reviews were good. Other brands much cheaper but people complained about plastic breaking etc. So far so good. If your usage is the same as mine then don't toss the Velcro strap securing them. Keeps them together as a unit. The strap is not the handiest to mess with. Maybe use another set for leveling + a small box however I still use wood blocks for the 4 corners as they pack better 4 me.

Great! Use them to support tongue jack all the time trailer is parked. No cracks, still solid, supports about 500lbs. Bought cheapies & wasted my $ prior to these.
Dale - 06/20/2020


After unpacking the leveling blocks, I could see they were made to handle the trailer weight. Have had bad luck with the yellow blocks, first time use the splintered.
These look way stronger. will use them in August on our next trip.


I have not used them yet but upon arrival seem sturdy and like they will work well


Convenient leveling blocks or jack pads for smaller trailers. Not worth much for heavy RVs and gravel sites. With much weight on gravel sites, the gravel deforms the interlocking teeth on the bottom of the pad making them very difficult to stack back together. For something like a travel trailer, these would be great.


Quick and easy to use on all types of s urfaces




I use these levelers under the wheels of my travel trailer for side to side leveling. I like the short "ramp" on each block and I like the modular wheel chock that you can purchase that connects to these.


Pleasantly surprised with this product. I was concerned about setting it up to lift both wheels of my twin axle trailer but two of these squares easily fit between the two tires. That allows me flexibility up to 3-1/2 inches (two nose to tail on the bottom and then two more "stacked" without offset) which is more than I got hauling around four 2x8s. And these are lighter and easier to transport. I'll still need my wife to guide me backing on but she has various other uses also, so....


These Stackers work great. They haven’t bent or broken in use and are apparently quite sturdy. My 5er weighs 10,000 lbs and the Stackers supported it in loose gravel for 3 months without deforming them. Only con I can see is when gravel gets forced up into the Stacker it is hard to dig it out sometimes and then they won’t Stack properly until the gravel is removed. I would buy them again.


These are awesome... anything that saves you time when leveling up your RV is so worth it. The refrigerator needs to be level for optimum performance. When it comes to sleeping the same is true for a good nights sleep. These Valterra stackers are a nice additional option for your RV. Light weight, sturdy and colorful so they are not left behind. Happy Camper... usually the result of a good nights rest. Keep it on the level. Big D


Very sturdy, size makes stacking to different heights easy.


The stackers worked just great! We are using them as Jack pads rather than for leveling. Easier, lighter and more convenient to carry than pieces of wood!


My first order a month ago was shipped promptly and the products, a brake controller and towing mirrors, were high quality. This prompted my second order, which arrived again promptly with excellent products. I seldom answer review requests, but this company deserved every bit of a five star rating.


Great product. I use them every time I park my camper.


These should work great to level my truck camper. They are strong, lightweight, and easy to stack and stow. etrailer personnel were very helpful and friendly with super fast shipping!


Have not used the blocks or cord adapter yet, but very pleased with the service. Web site was easy to use and product arrive as promised, on-time, and nicely packaged. I will order from them again.


Tried blocks out next day received just to see and works great seems to look as if they will last a while. Outstanding people at etrailer and Dana was very helpful and even upgraded my shipping after I had to switch my order because they did not have what i first order. Etrailer has my business here on out . 5.5 Stars


Great price, delivered quickly , light weight and seems to be strong material that will level our new rv. I now realize i should have bought the accessory stop block and will be doing that.


These levelers are a life saver. Not all sites are created equal. I’ve used them for slight adjustment to up on the very edge for max adjustment. Don’t camp without em, they work great!

  • Do Stackers Need to be Used on all Three Axles on Triple Axle Toy Hauler?
    That's an interesting question, but leveling blocks such as # A10-0918 should be used on all three axles to properly support your toy hauler. Your axles each have a weight rating and you would not want to take one out of the equation entirely. If you plan on using these blocks you can help keep your wheels in place with wheel chocks # A10-0922. I've added links to video reviews of each product for you to take a look at.

  • How Much Lift Do Stackers Leveling Blocks Provide
    The total height of each individual block on the Stackers Leveling Blocks # A10-0916 is 1-3/8 inches. All four blocks included in the set need to be stacked on top of each other to provide the total 4 inches of lift. I have included a helpful demonstration video that explains these dimensions. Since you are needing 8 inches of lift, I instead recommend the part # A10-0918, which is the same product but includes a total of 10 blocks. I also recommend adding the Stackers Wheel Chock #...

  • How Can I Make My Trailer Jack Stand Taller
    I have a solution for you, but the Valterra # A10-0900 is going to be the tallest jack stand that we have available. I recommend using one or two of the Stackers Leveling Block # A10-0917 under this jack stand to give you enough clearance to easily release the tension bars and remove them from your weight distribution hitch. You can also get a pack of 10 Stackers Leveling Blocks with part # A10-0918. Each Stacker Leveling Block will add 1-3/8" of lift to your jack stand.

  • Troubleshooting Out of Stroke Error on LCI Ground Control Auto Leveling System
    The Out of Stroke error message on the Lippert Ground Control system, such as # LC358590 indicates the jack has extended as far as it will go and has maximized it's extension. To clear the error you can extend all of the jacks in the system at least 6 inches. Then press and hold the retract button until the jacks start to retract. All of the jacks should fully retract and the error should be cleared. You would then either need to move your camper to a more level location so your jacks...

  • Recommended Leveling Blocks for RV with Closely Spaced Tires
    I spoke with my contact at Andersen regarding the Camper Wheel Chock and Leveler # AM3604 referenced in your question. He stated that while the levelers are designed to work with most tandem axle setups, there are rare instances like yours where the tires are simply too close to each other for them to work without alteration. In these cases, the only real solution is to simply trim down the level as you mentioned so that it can fit between the tires. If you do not wish to do this, a better...

  • Dimensions of Stackers Leveling Block # A10-0917
    The Stackers Leveling Block # A10-0917 is 8-3/16 x 8-3/16 x 1-3/8. If you measure out to the edge of the handle on the side it is about 10 inches total. I've attached a video to assist. These are available in kits as well ( # A10-0916, # A10-0920, # A10-0918)

  • Axle Ground Clearance Needed For TrailerLegs Tire Saver Stands
    The TrailerLegs Tire Saver Stands - Tandem Axle # 326-TRLLG-4 have overall dimensions of 15" long x 8" wide x 19" tall. In order for the rubber to grip and allow lift your axles will need to be a minimum of 11-1/2 inches off the ground. The manufacturer recommends using some wheel blocks like # A10-0918 to increase the height of your axle from the ground if needed to assist in making this system work ideally if your axle height is less than the 11-1/2 inches.

  • Are There Leveling Blocks Wider Than 8-1/4 Inches?
    Each of the leveling blocks we carry have a width between 8-1/4 inches, such as the Ultra-Fab # UF48-979052 you mentioned, and 8-1/2 inches, such as the Stackers # A10-0918. The Stackers have a 40,000 lbs gross vehicle weight capacity and can be used for scissor jacks, hydraulic jacks, fifth wheel jacks, and stabilizer jacks.

  • Comparing the Ultra-Fab and Stackers Leveling Blocks
    The Lynx Leveling Blocks you have will not work with the Ultra-Fab Leveling Blocks part # UF48-979051. The reason for this is that the surface pattern which is used to lock them together is different. You would need to either purchase more of the Lynx Leveling Blocks or a new set of Ultra-Fab Leveling Blocks. In order to minimize the amount of blocks needed to level your trailer you may also be interested in the Stackers Leveling Blocks part # A10-0918 which are 1-3/8" tall compared to...

  • Stackable Block Solution for Center Jacks of Lippert Ground Control System
    Best solution we'd have would be with the Stackers part # A10-0918 which allow you an easy way to "stack" blocks to help take up the extra height you need to allow your Lippert Ground Control kit to make contact sooner. You can also use these to make ramps for your wheels too to help change spares.

    The # UF48-979002 feature oversized footplates that are 4-1/2" wide by 9" long, so you could use them without leveling blocks. However, it's not uncommon for people to use leveling blocks like # A10-0918 or even wooden blocks under these jacks to provide extra stability (see photos). This is especially helpful in soft surfaces like grass or dirt. What you do want to make sure is that you chock your wheels to prevent your travel trailer from rocking and rolling when parked.

  • Availability of Individually Controlled 4-Jack RV Leveling System
    I believe you're looking for something like the Lippert 3.0 Ground Control 3.0 system. Unfortunately, Ultra-Fab doesn't offer a product that would allow you to individually control 4 separate jacks. The only product we offer that would do that is the # LC358590 Ground Control 3.0. Another option would be to use two of the Ultra-Fab # UF39-941705 Power Twin II, but you'd also need leveling blocks like # A10-0918 because both feet on each stabilizer jack are controlled at the same height.
