EAZ LIFT 48860 Telescopic Jack, (Pack of 2)

Update December 2018: still awesome! Three months in constant use and they're looking great. I HIGHLY RECOMMEND using grease on the threads of these, and any screw jacks. They function much better with grease, including a small bead under the top support pad so the jack post can spin freely under the support pad.Bonus feature: I used four of these to hold my 5th wheel up while I temporarily retracted my landing gear to fix something, too. Worked great! Test would work but I believe in redundancy for safety.As for the top pin setting, these are for support and while they could lift your rv on their own, they're best used just to eliminate bouncing and the top setting will work fine, despite looking wobbly without a load. I wouldn't support anything with ONLY these jacks on the top setting for stability reasons, but they'll be fine providing partial support at maximum height.Original review, September 2018:I'm really happy that I purchased two pairs of these jack stands, they helped a lot with the bounce I was experiencing when walking around or when someone else was walking in the RV. I can even feel the difference between walking around, it feels more solid, like an actual foundation. I have a 35 foot Keystone Montana and replaced the jack stands behind the rear axle and another pair halfway between the front and back of the RV. I've uploaded a video to show what they are like. These looked better than the small aluminum model Camco also makes, and EACH is rated for 6000 lbs. I won't be doing it, but they could theoretically support the entire RV themselves.They do seem a little "loose" at full extension but I see no need to use that top pin setting. The internal screw adjusts a lot.Between these and x-chocks all I want to do is brace my super slide, and remove some sway up above the kingpin, and I'll get a strong arm kit or similar for that.

These work well one my camper to add additional stability to the built-in stabilizers. The full adjustability is a must have, especially due to the uneven terrain I can encounter at some campsites.These are much heavier than traditional jack stands or supports. However, that weight allows a construction which provides more adjustability than traditional stands.

These stands are top quality

I used these to support and stabilize the rear of my 10,000 lb 35 foot RV. My old scissor jacks had been damaged and I have not yet decided on a permanent replacement. These looked great and worked really well but almost nothing is perfect. My biggest complaint is the lack of another adjustment hole for the pin. there is two holes in the lower part of the shaft and another at the top but there is a large gap between the lower set and the upper hole. The stand has three legs and the missing hole would hit at the top of one of the legs.It was done to save the hassle of cutting the top of the third leg and to save a little money. When I got back from my trip, I drilled a hole in the missing spot and it was a little hassle with a hand drill but makes the whole stand much easier and safer to use. (When I needed that adjustment, I had to compensate, I had to unscrew the threaded portion several inches to make it the correct height.)Make sure the ground under the stand is good and solid. Once it rained and the ground became soft and one side of the stand sank. This caused the stand to tilt and dropped the camper. The threaded shaft was bent because of the extended lift that I was using. It was not the jacks fault! Afterwards when the ground looked soft, I used a larger base under the stand for extra stability. I was able to cut the threaded shaft and just use the upper section so it is back in business.The missing adjustment hole is what keeps this from getting a 5 rating.

Worked great, would buy again

I use a pair of these centered along my 42' fifth wheel. Easy to set up and easy to tighten into place. They are NOT for lifting. Having shopped around for jacks for my trailers over the years, I see so many reviews for stabilizer jacks where they get bad ratings because people are morons and use these for lifting cars off the ground. When using them for stabilizing my fifth wheel, I have them on simple ground pads. I would not set these directly on the ground unless its a hard surface. Then tighten a few turns against the frame rails of the trailer. Now, no more bouncy feeling along the center of the trailer when inside and substantially cuts down on the rocking throughout. Really there is no getting rid of all the bounce in a trailer. All you can do is try to subdue it by locking the wheels/axles as best a possible and then putting as many stabilizer jacks as you can to support the frame. At this price, these help tremendously. Not that heavy, easy to use, and get the job done. I would buy again, if needed.

I had my large pop-up camper (sleeps 6, has a/c, toilet, shower, sink, stove) raised about 10 inches to increase clearance and my old aluminum jack stands were no longer tall enough to reach the frame to stabilize the camper. After attempting to build risers and deciding against it, I ordered 2 sets of these stands. They arrived quickly and worked as expected. I was concerned that they would be too wobbly when extended and while the camper does wobble a bit while all set up, it is an acceptable trade-off for the additional clearance. These are very well built, the pins are strong, they adjust easily and the 3-point base should be very stable on a variety of terrains. Would recommend to those looking for taller, stable stands.

Perfect for heavy trailers
