Rated 5 out of 5 by from love this jack love this jack ! I put it on the other day and it works great i don't hit the ground when i pull in the yard anymore . it's adjustable and also more heavier made than the original
Date published: 2019-04-11
Rated 5 out of 5 by from Great except for one little thing I bought this because I had to remove the old one everytime I towed the trailer behind my 5th wheel. I has solved that problem but the design is flawed. The from bolt cannot be installed without trimming the black slider about 1/4" on the bottom fr of the base. I put in a carriage bolt and now it works great.

Rated 5 out of 5 by from Wow. Nice trailer Jack I've very happy with my new jack. Fit like a glove. I wish they had included mounting bolts. I would have bought an optional wheel attachment had they offered one. It could be longer.

Rated 5 out of 5 by from Best Trailer Jsck This Trailer jack makes hooking up and unhooking so easy also if you need to drop tailgate on truck just release pin pull lever It drops to ground now you can open tail gate and no dents in it / puts all other Jacks to shame
Date published: 2019-01-18
Rated 3 out of 5 by from Great feature for the pull pin to raise and lower I bought this several months ago and I like it except it is to light for a 16' trailer but works good on a 10' trailer. If they made a heavy duty jack like this I wouldn't have any other kind. Because of the feature of pulling the pin and being able to remove it from the trailer so you don't beat up the tailgate. It also saves the jack from getting caught on the ground when driving in uneven ground. I would have giving it a five star rating if it was heavy duty. I would recommend this jack for a light weight trailer only.

Rated 5 out of 5 by from Best Jack Out There!! I bought this jack because I was tired of having to crack jacks up every time I unhitched the trailer. This design is a HUGE time saver. It's also very heavy duty. I screwed up part of the shaft when I first used the jack, and customer service was very responsive and very helpful. Also love that it's made in the USA. GREAT people, GREAT product!!

Rated 4 out of 5 by from Easy to use With the locking feature, much less cracking is needed in both directions.

Rated 5 out of 5 by from Great Design! Replaced my second Bulldog jack that kept hitting the ground and getting destroyed... "going in and out of uneven driveways. This jack retracts up via a spring loaded pin. I highly recommend." I wish I would have thought up the design..

Rated 5 out of 5 by from Solved my dragging problem I tow a trailer with a 2012 Challenger SXT Plus, so it is low to the ground. Last jack kept dragging when I went down bumpy roads due to it not retracting enough. This jack retracts all the way into the tongue so no more dragging. I love this jack!

Rated 5 out of 5 by from love it love that trailer doesnt drag on the ground behind the four-wheeler
Date published: 2018-07-31
Rated 5 out of 5 by from Great drop foot jack. I have owned several different brands of drop foot trailer jacks over the years and this is by far the best one I have ever owned. I installed this one on a 6 x 12 UTV trailer and it is the perfect height and size.The ease with which the quick release locking pin locks and unlocks makes all the difference. If you follow the instructions and raise the jack, its almost impossible to bend a jack, even if you go through a ditch or over a bump. I will install more as my other trailers need new jacks. Great trailer jack.

Rated 5 out of 5 by from Jack escaping the ground ? Buy this Jack ! Exact fit replacement for my Bulldog jack that kept scraping the ground going in and out of uneven driveways. This jack retracts up via a spring loaded pin. I highly recommend.

Rated 5 out of 5 by from Great idea For me I had to do a little tweaking on my trailer but now it works like a charm. I thought it was an issue with the product and I sent an email. With in the hour i received a call on a Sunday. Not only is it the ultimate jack but you get the ultimate customer service. Thanks guys.

Rated 5 out of 5 by from A great solution to dragging our jack post on dips Our BSA troop has a small enclosed trailer, which is pulled by several vehicles. Some combinations (and terrain) caused the jack to drag, as it couldn't be raised up far enough. I saw this on a friend's trailer and so glad to find it here. Just installed and it works great.
Date published: 2018-04-11
Rated 1 out of 5 by from I thought is was a good idea. I put this jack on a utility trailer. Never unhooked while loaded and the jack will no longer slide all the way down or all the way up.
Date published: 2018-02-21
Rated 5 out of 5 by from Liked mine so I purchased a second as a gift. I bought one originally for a utility trailer and it works great. It's great for shortening the time lowering and raising the trailer on/off of the hitch. It operates smoothly and skid or wheel attachments work as well (as expected). It's quite sturdy and never misses a beat, even with heavy loads. Purchased another for a gift and it is well received!
Date published: 2018-01-04
Rated 5 out of 5 by from Performs very well as described I installed this as an upgrade to the standard height trailer jack that would drag the ground sometimes. The extra upward clearance this model has will allow me to use the plate or wheel attachment without having to remove each time. One issue was the instructions called for washers under the bolts but no hardware was included. The factory bolts and holes lined up just fine. The body of this jack is wider diameter that a washer wouldn’t fit, nor a socket wrench. Installed using factory bolts and open end wrench just fine. Would have thought this model would have come with special shaped washers.

Rated 2 out of 5 by from Good idea I bought this product about 2 weeks ago. It is a good idea but ad design, was trying to hook up to my truck went to crank up to higher and the jack fell apart. Got my knee and foot. Will be returning this product, hope for a better design soon.
Date published: 2017-10-29
Rated 5 out of 5 by from Fantastic Jack This is the third one of these I've bought and can say they work great. No more cranking your arm off, especially if you drive a 4 x 4. Highly recommended.
Date published: 2017-10-19
Rated 5 out of 5 by from Wish I had thought of it Third one I have bought to replace the existing jacks that came with the trailers. A lot easier to use than getting down on your hands and knees to insert the pin in the shaft below the tongue. No doubt will be replacing a fourth when I have the time.

Rated 2 out of 5 by from Be careful with this jack I used this jack for my horse trailer about 8 times.. really liked it.. then was hooking up back in April and I had to pull pin to raise.. cylinder didn't lock and trailer collapsed on my foot breaking all bones in my foot.. 2 surgeries.. still in PT and still limping.. don't think my foot will ever be the same..
Date published: 2017-09-10
Rated 3 out of 5 by from Ulitamate jack Bought it 8 months ago, it was awesome at first but after a few months it started to loose its lift capability after 5 months I had to start using lower holes then eventually it lost the total lift height and had to buy new jack very unhappy with overall due to cost and durability
Date published: 2017-06-29
Rated 5 out of 5 by from Great Quality I have used this jack for a giveaway trailer and the new owner loves the jack. I also use this jack everyday because it's great quality and it's easy adjustable shaft. Is your tailgate hitting the jack? Sick of putting wood or brick under jack to get trailer off your tow vehicle? Those problems easily solved with this amazing jack.

would this be a good jack for a log splitter

Asked by: raymond915
The ultimate jack will work on a log splitter provided it has A-frame mount capability. If it has the hole in center of hitch, it will work.

How long is the cranking handle from the main vertical shaft? i.e. How much clearance do I need to crank the handle around 360 degress? My propane tank currently sits just aft of my jack. Thanks

The cranking handle measures 7" from the vertical shaft. Giving you a diameter of 14".
