Features to know about
Keeps Your Setup Solid: Steel Scissor Jacks with 15,000-lb Combined Capacity
Nothing spoils a campsite faster than a trailer that rocks with every step. This pair of leveling scissor jacks holds steady with a combined capacity of 15,000 lbs—7,500 lbs per jack. Each one extends from 5" to 30" so you can take the wobble out of uneven ground. The bow-tie base keeps them planted on softer surfaces, giving you a solid, secure feel once you’re parked.
Simple to Mount and Use: Bolt-On or Weld-On Installation with Crank Handle
Getting these jacks set up doesn’t take fancy tools or custom brackets. Each unit mounts directly under the frame using bolts or welds, and the included crank handle fits the 3/4" screw that raises and lowers the jack smoothly. With both installed, you can steady your rig in just a few turns.
Built to Last Outdoors: Heavy-Duty Steel for Long-Term Stability
Rust, grit, and road spray are tough on gear, but these jacks are built from strong steel to handle years of use. The wide base helps spread weight evenly while resisting sinking into dirt or asphalt. When collapsed, each measures 32-1/2" long and 4" high for a low-profile fit that stays out of the way when not in use.
Ready for Leveling and Storage: Up to 30" of Adjustability
Whether you’re setting up for the weekend or storing for the season, having the right range makes all the difference. With up to 30" of lift and a retracted height of just 4", these jacks give you the reach to level your setup anywhere while staying compact when stowed. They’re designed to stabilize a portion of your trailer’s weight—not to lift it completely—so your frame stays supported and steady every time you park.

The jacks are very nice and sturdy, however the mounting bolts are very subpar. I ordered a pair of these a year ago, or two ago, and had the same problem with the bolts stripping out. I followed the instructions and drilled an 1/8” pilot, then a 5/16” hole, but they stripped out each time.

This is a good product. The jacks are made well and very sturd. The instructions are good but the 5/15 hole it says to drill is too small to to get the included self tapping bolts to thread into. I wound up purchasing some 5/16 bolts to secure them to the frame of my rv.

The jacks are fantastic. The hardware sucks. I read the reviews that basically said the same thing. I went ahead and ordered them and figured I would see for myself. Turns out the reviews were correct. It would be a simple fix to improve the hardware but I guess it’s too much to ask. My other suggestion would be to include actual printed instructions for us old school folks.

The JSC-30 jacks were disappointing when functioning. The quality of the worm gear was a rough function like there was a washers missing. My old pairs had washers creating smooth function and no wobble. The only reason they got a three star is that they are rated at 7500 lbs x2 and not the 5,000 lbs x2 as advertised. Etrailer.com shipments have been right on time and I do appreciate their email updates.

The jacks work perfect. The only issue I had was with the supplied mounting screws that came with it. I drilled the holes as it said to in the instructions. All of the screws stripped out. I had to run to the hardware store and get some with case hardened with nuts to mount them. That was the only issues I had. The jacks seem stable and there’s no rocking of the camper.

Glad the jacks are working well for you, Lloyd! Sorry about the hardware though. I think this is the first time I have heard all of them failing like that. I will have our QC guys check out our current stock to see what's going on with that. Hopefully all of them aren't including soft self tapping screws. What kind of camper did you install these on?

They are so nice go up and down with ease and are taller than my last ones making it easier to level without blocks. Our first trip with the new lifts is coming up and we're excited to try them out.

Glad I went with the 30” version, however the “self tapping” bolts that come with it will not work on the steel mounting beams as the steel is too thick and the bolts just strip even pre drilling according to the instructions. I had to get some bolts with nuts and lock washers as I didn’t want to weld them

These jacks are solid and easy to install. Do not come with mounting hardware. I used 5/16” x 1.5” bolts with washers and lock nuts. Also added some locktite to be sure they don’t come loose. Standard attachment on most trailers seem to include one or two bolts, then the rest with self tapping screws, which isn’t very secure in my opinion. I had to drill out some of the smaller holes to fit the 5/16” bolts but an easy job for a DIY project. Thanks etrailer for selling a great product and quick delivery.

2 of the jacks on my trailer were bent and difficult to operate. Purchased this set as replacements, removed the mounting plate and they bolted right in. Perfect match and they work like when the others were new. Ordered them on Wednesday they arrived the following Monday. Nice easy process.

- Economical Leveling Jack Recommendation for Ambulance with Drill OptionHey Michael, so scissor jacks are going to be the most economical solution for leveling your ambulance when parked like the # JSC-30 and then for a drill attachment to make raising and lowering them easier you would just need the part # SC83TR and you'd be set. The faster the drill speed the faster it will operate them but you don't need anything special.
view full answer... - Stabilizer Jack Recommendation for Stored Boat Trailer To Support While in StorageScissor style stabilizer jacks like the Leveling Scissor Jack Set # JSC-24 would be your best option. These were designed to stabilize camper trailers but would work great for what you are wanting. I attached a picture of what they look like in use plus a review video for more info as well.

- Recommended Jack Stands to Elevate Boat and Trailer for Storage with Weight Off TiresFor your boat trailer, to keep the weight off the tires for storage, I recommend the 2-Ton Jack Stands - Qty 2 # PTW41021. Each jack can hold 4,000 lbs, but I recommend using 4 of these spaced as evenly as possible to keep the weight off the wheels and then just use the trailer jack for a 5th point of support and balance.

The Thule RV Wheel Levelers item # TH307617, you were looking at, have three different leveling heights; 4-1/2", 3", and 1-3/4" and are only designed to be used as a pair. They have a 10,000 lbs capacity. For what you're talking about you would want to use a leveling system or a scissor jack set up like item # JSC-30. What kind of motorhome do you have?

view full answer... - Manual Stabilizing Jacks For Class C MotorhomeThese manual scissors jacks are for stabilization and not for leveling, so if you want to level out your Class C Winnebago Vita motorhome then you will need leveling blocks, the Ultra-Fab Leveling Blocks for Trailers and RVs # UF48-979051. Then for stabilizing jacks, ground clearance should not be an issue, no, and what you will need depends on the distance from your frame to the ground. The Stromberg Carlson Scissor Jacks have a 5,000 lb capacity per jack and each has a retracted height...
view full answer... - Can the Leveling Scissor Jack Set Be Used On a Class C MotorhomeThe Leveling Scissor Jack Set part # JSC-24 can be mounted on a motorhome yes. In regards to installation, the jack will need to be attached to a part of the frame but there aren't many other mounting restrictions. However, I do recommend you check your ground clearance once mounted so you don't have any issues with them scraping. That said, please note the above jacks only offer up to 24" of lift so if you need more than this then you will have to go with the Leveling Scissor Jack Set...

We do not have a jack of similar construction that is longer but there are options. We carry 30 inch tall scissor style stabilizer jacks, # JSC-30 (single) and # JSC-30-IND (pair), that would most likely be a better fit with the 25 inch frame height on your Military M101 A2 trailer. This would most likely be the best option for you. We also have the stabilizer leg, # FSJ20324,...
view full answer... - Replacement Scissor Jack Recommendation for a 2018 Forest River Rockwood Mini Lite 2507SWe have a handful of scissor jack options you can use as a replacement for your 2018 Forest River Rockwood Mini Lite 2507S but we don't have an exact part number for what came with your trailer. I recommend picking up the Stromberg Carlson 5K scissor jack with the 30" lift so you get the highest lift and a good, solid weight capacity at 5K per jack. Here are the part numbers for single and double kits: - Single Leveling Scissor Jack # JSC-30-IND - Leveling Scissor Jack Set # JSC-30
view full answer... - Recommended Replacement RV Scissor JacksThe upgraded scissor stabilizer jacks that I recommend are the Leveling Scissor Jacks with Handle part # JSC-30 which have a 10,000 lb capacity and offer up to a 30" lift. They also come with an easy to use crank handle. They can be bolted or welded to the frame.
view full answer... - Can Scissor Jacks be Used to Level and Stabilize RVYou can use scissor jacks to level out your 2019 puma 32bhdb travel trailer like with the Leveling Scissor Jack Set # JSC-30 that you referenced. This is a quantity of 2 so with two sets of this you'd have a less expensive way to level and stabilize your trailer. Scissor jacks work really well but they require manual raising and lowering as opposed to some of the other options that level with a push of a button like the Lippert Ground Control # LC672136.
view full answer... - Can Stabilizer Jacks be Used to Lift RV a LittleTo answer the last question first, a stabilizer jack such as # JSC-30 would be used until there was just enough tension to keep the trailer or RV from rocking. For actual lifting you would need a different device. So assuming that the RV was level these stabilizers would help prevent it from rocking back and forth or side to side (depending on where they were mounted) while you move around inside. If you were to try to lift weight with them you would have a very hard time because it just...

- Dimensions Of Stromberg Carlson Leveling Scissor Jack SetI was able to find the dimensions of the Leveling Scissor Jack Set - 30 Lift - 10,000 lbs # JSC-30 you were looking at as shown in the included diagram, but unfortunately Stromberg Carlson does not have any CAD or technical drawings of the jacks. The # JSC-30 measures 32-1/2" long, 4" tall retracted, 30" tall extended, and the mounting bracket is 10" long. The foot is 9" long x 4-1/2" wide.

- 2018 Jayco Melbourne Power Leveling Jack RecommendationsFor your 2018 Jayco Melbourne, I recommend the Ultra-Fab Power Twin II Electric Stabilizer part # UF39-941705. This leveling system works with frame rails spaced between 48" to 80" apart.
view full answer... - Recommended Leveling Jack System that Bolts onto Chassis of Mercedes Sprinter MotorhomeI recommend using the Leveling Scissor Jack Set, # JSC-30. This set is designed to be bolted or welded to a flat surface on the bottom of a motorhome frame rails or chassis. These 2 leveling scissor jacks with 5,000-lb capacity each will keep your motorhome level and stable. Each adjusts from 5" to 30" inches as your situation requires, and the bow-tie base steadies the jack on soft surfaces. These stabilizers will help prevent your motorhome from rocking back and forth or side to side...
view full answer... - What Size is the Screw Portion of the Leveling Scissor Jack Set, # JSC-30I spoke with my contact at Stromberg Carlson and she stated that the Leveling Scissor Jack Set, # JSC-30, uses a 3/4 inch screw to raise and lower the jack. So the included handle would accept that 3/4 inch screw.

If you typically need blocks to make up the additional height to the ground you can switch to 30" jacks with the # JSC-30. I have attached the dimensions of the installation brackets below. If this doesn't match what you currently have, you can unbolt the jacks from the bracket and install them with your current brackets for a direct fit.

- Adding Front Stabilizer Jacks to a 2010 Forest River Rpod 174For your 2010 Forest River Rpod 174 I recommend the Leveling Scissor Jack Set # JSC-30. These have a universal mounting flange with a low profile at 4" when fully retracted. They will offer up to 30" of extension for your camper to be stabilized. These will work best mounted at an angle to the trailer rather than paralleled with either the front or side. To make it easier to move your stabilizers up and down a Ultra-Fab Speed Socket Power Drill Adapter # UF48-979005 can be used with a...
view full answer... - Why Shouldn't Scissor Jacks be Used to Support Trailer Getting Loaded with Car UnhitchedI wish I could say yes, but scissor jacks like part # JSC-30 really aren't designed for that type of application. What you are trying to do becomes a little bit sketchy because the nose of the trailer is going to want to climb as well as the trailer roll forward so basically it's a recipe for disaster. You really would want to load and unload the trailer with it connected to a truck.

A better solution is the TrailerLegs Tire Saver Stands # 326-TRLLG-4 which support the RV by the axles. The stands take all load off the tires which will prevent bends to the steel belts; bending of the belts is non-reversible. The stands will...

- Scissor Jack Options With A Low Retracted HeightHello Al. The Scissor Stabilizer Jack # TJSC-24 has a retracted height of 5". Meaning if the current jacks are at 5-3/4" you will gain 3/4" of clearance. if you are looking to gain as much clearance as possible, I suggest you take a look at the Leveling Scissor Jack Set # JSC-30. These have a retracted height of 4" and will be the "shortest" scissor jacks we offer.
view full answer... - Can More than One Set of Scissor Jacks be Used on TrailerEach jack of the Scissor Jacks part # JSC-30 are rated for 5,000 lbs of stabilization. That means that they can stabilize up to 10k if you do a set of two. That doesn't mean lift the trailer off the ground though. Most people have luck with just a single set but if you wanted to run them on all corners of the trailer you would get a rock solid setup.
view full answer... - Winch Recommendation for a 1998 Rockwood Pop Up CamperFor an economical brake winch that should work well on your pop up camper trailer as long as it would fit in the boxed area of your trailer frame I would recommend the Fulton Hand Winch # F142007. This winch should work well as a replacement for your trailer, I attached a review video for you to check out. You may find that you would have to mount the winch on top of the frame instead of inside it. Otherwise, your best option would be to find the exact model you have on your trailer frame...

The product is still working as intended. Routine maintenance, such as cleaning the footpads and greasing the screw, is needed to keep them moving freely. I will purchase again if I ever need an additional one. I purchased 6 of the jacks due to the length of my travel trailer. They are attached near the corners and in the middle. This setup has eliminated the sag in the middle and provided solid support, reducing movement when the kids are running about.
