The Blaylock EZ trailer jack and wheel chock makes it easy to change or service a tire on your dual-axle trailer. Simply place the wedge in front of the tire that does not need to be changed. Pull the trailer forward (or backward) up onto the EZ Jack until the flat tire is up in the air.


Flip the wedge over (rocker-side down) to use it as a wheel chock on a flat surface or an incline. Simply turn the wedge upside down and place it in front of or behind a wheel.


Keep the wedge rocker-side up to level out your RV when it's parked on terrain that is not level. Set the unit in front of the tire, with the narrow lip under the tire, and drive your RV forward until the motor home is level.

The EZ-Jack works great. We have used it many times in the past year to level out the pick-up truck and camper, mainly for sleeping comfort. It is very quick and easy to place, and then drive the pick-up onto the jack. We have used it on a variety of substrates, from gravel, soft dirt, to cement. It remains solid in place, no scooting or movement. Smooth to drive off from too. Highly recommend it.

Saved my life on the side of the interstate [south of Montgomery, Alabama (I-65)] ! It was the first time I used it & I looked like a NASCAR pit crew I was moving so fast. Why won't people move over when they see a driver in distress ? Placed the EZ-JACK under the wheel (Gooseneck trailer) , backed up about six inches & That's all it took to make it where I could take the blowout off & put the spare on. I'd recommend doing a good look over when taking it out of the box & file any burrs of before storing it. I'm considering buying another one for the Toy hauler!

Fantastic, Saved my fanny on the side of a Interstate. Believe me, thats no place you want to be! I felt like a One Man NASCAR Pit Crew. FAST, SAFE, Back in the truck where I should be. Not playing dodge ball with Eighteen wheelers!!!

My trailer has a really wide axle spacing so I was a little worried that it would provide enough lift to get the wheel off the ground. The first time, it worked beautifully. The wheel to be changed had more than in inch of clearance to the ground.
Unfortunately, I forgot to install the center-cap with the new wheel so, I got to practice doing it again. This time two concerns arose. First, the EZ-JACK sunk in the ground just slightly mainly because I did not position it perfectly in line with the tire so, it tilted slightly causing it to sink in the ground a little which brings up the second concern that it can get sideways and this could be dangerous. Subsequently, I put a piece of plywood under it which served to stabilize it from the shifting ground not to mention that I made sure to square up the EZ-JACK to the tire.
Ordinarily, the EZ-JACK would be on asphalt or concrete but, still might be good to place a nice piece plywood down and be dang sure you align it with the tire.
Also, worth noting, this is a 10Klb trailer, so.


Worked as advertised - needed to swap two tires on a tandem axle boat trailer and this got it done quick and easy. Unit is lightweight but feels durable and strong

Works great after a year probably used 5-6 times total, no cracking or other integrity issues

I've used this to change a tire along the Dalton Hwy as well as to level my travel trailer side to side while boondocking and recomend this to anybody and everybody who has a tandem axle travel trailer. It will not fail like some reviewers of the plastic or composite product have reported. For me, it does not eliminate the need to carry boards as I don't like all the weight on one axle for more than a tire change. Also may need to put a board under it on soft or sandy ground. Would definitely buy it again.


Friends recommended this product and I'm comfortable they are the answer to changing tires when needed and chocking when the tires are on blocks.


A must have for anyone with a tandem axle trailer. If the fenders get in the way just flip the ez-jack over so the arch is up.


Unit is sturdy but you have to make sure your trailer is high enough as when I tried to use with our horse trailer it would go up and hit frame of trailer when trying to drive up on it.


Exactly what my boys needed for their horse trailers!


Love this monster. It's big and built like a tank. The large size gives you several inches of height versus some of the smaller, plastic versions. Each has it's place in the tool kit, though. Bought this primarily as a quick way to level an RV for overnight stays instead of using blocks or hydraulic jacks. I recently used this to "jack" my RV up to replace a flat tire and it did the trick. Somehow I managed to back off of it and it wedged between the tandem trailer tires. Had to remove the rear tire to get it out but since that was the flat one it was going to have to be removed anyway. Point being: drive up or back up (depending on if it's the front or rear tire you want to elevate, but DO NOT accidentally drive all the way or back all the way off of it to the point where it gets lodged between both tires. It was muddy and I think the tire spun and that shot it up between the tires. Driver error; not any fault of the Blaylock. Would've been great to have a second set of eyes but I was working solo. Anyway... it can be a leveling jack or a tire jack. Great product and well made.


This is a great product! However, one downfall, not to any fault of the manufacturer, but it doesn't;t work f you have leveling jacks. It doesn't clear them and can't use it.


WELL MADE AND CRAFTED they work great for changing wheels or leveling my trailer on really unlevel camping spots. So far I haven’t had to use them, but they look like they will save my back a lot of Grief. I have a bad back, and needed something simple to do these jobs easily.

I decided not to use to use these for Wheel chocks or levelers. I’m just gonna use it for changing tires. Beings after all aluminum, I am afraid someone will steal them. Beautifully made but a big chance they could walk away.

I had to put a 2x6 under the good tire in order to get clearance on the fender, but it works great and has really good lift height. I just hope that I don't have to use it often.


Excellent service as usual. Almost take it for granted. Product is what I ordered, heven't used it yet but do not anticipate any issues.


Quality product! I have a dump trailer that I take to the landfill and I am always picking up nails / having flat tires. This jack will save me lots of time and it is much safer that the jacks that I have used in the past. I bought 3 of these, one for each trailer.

Really good, I had a flat on a major roadway with a tractor on my trailer. The jack helped me to be up and running with the spare tire installed in less than 10 minutes

Ok for leveling. It does not lift the other tire off the ground without additional blocks. It is heavy duty casting. Time will tell how strong it is.


This lifts my trailer up enough on one wheel to remove the wheel I want to remove. It is also good for leveling.


I've only had one opportunity to use the EZ-Jack and unfortunately, it didn't turn out very well. I had a tire go flat on my 20' tandem axle goose neck trailer while it was loaded with about 11,000 lbs of hay while it was parked in the hay barn. I first tried to use the EZ-Jack on the concrete floor but it would slide out from under the tire when I tried to back onto it. It is a very slippery with hay dust and chaff so I decided to try using it outside on the gravel driveway. This time I was able to get the EZ-Jack to stay in place but it wouldn't lift the front axle high enough to be able to remove the tire! The ground was somewhat soft due to recent warm and wet weather but it wasn't even close to being high enough to get the tire off. No time to be messing around in the cold weather so I resorted to using the tried and true bottle jack and have since added a low profile jack for those times when the axle on a flat tire is too low to the ground to get a standard height jack in place.

I haven't given up trying to make the EZ-Jack work, but just haven't had the time to mess around with it. If it doesn't work on the goose neck trailer, maybe it with work on one of my other trailers.


I received my Ez Jack yesterday. It is just what I expected in a sturdy built piece of equipment that I hope to never have to use. If I am unfortunate enough to require the need for a jack while away from home, I am confident that it will provide the necessary service to change one of my tires on the trailer.

I keep the Ez Jack in my trailer toolbox at all times. In the event that it is needed, I am confident that it will do the job.

I just received this but haven't used it yet. It appears to be heavy duty and solidly built. I expect it will work well.


Have not used this product as of yet but quality of workmanship looks to be very good.


Jack appears to be heavy duty...certainly no concerns of it being harmed when used with a normal weight trailer. I bought it for my 16' Haulmark cargo trailer (with leaf spring suspension). It works just fine. I did find that the jack conflicts with the trailer's fenders, but a quick and easy solution was to first drive the tire onto a short piece of full-sawn 2"x6" which was enough height to raise the trailer so the jack didn't roll up into the fender.


Absolutely love these. Far better than the plastic Anderson version. Did have an issue with them hitting the low front bumper on my Ram Promaster. My solution is to turn the front wheels slightly in the direction of the side I wish to lift just enough so that they clear the bumper. Then drive up on them as normal while keeping the front wheels turned slightly. This will keep them away from the front bumper. Make sure to dismount the same way. I also found that Reese Topower Wheel Chocks (part # 7000100) have just the right curve to slip under and support the tail of the EZ-Jack for stability when using the them as levelers for campers and trailers.


Excellent service and quick order fulfi llment


Great product. If you own/tow a tandem trailer do yourself a favor, get this EZ-JACK! I've had to use twice and each time has saved the day. I tow a 39' 5th wheel and have had blowouts on major highways and always have been able to change my own tires. This jack makes it EASY and FAST...
