This system uses stainless steel cables with sturdy springs to make it easy for you to raise and lower the tailgate on your open utility trailer. Units mount on both sides of the trailer to assist each side of the tailgate evenly, preventing warping.
Features:
Specs:
The Gorilla-Lift tailgate assist reduces the amount of force needed to lift or lower your tailgate. It is comprised of 2 separate units that mount to both sides of your trailer. With even tension applied to each side of the tailgate, the tailgate is able to be raised and lowered evenly, reducing wear on the hinges and helping to prevent warping. Each unit has a spring located in the back. This spring attaches to the cable that hooks onto your tailgate.
When you lower the tailgate, the majority of the load is taken on by the springs, thereby decreasing the amount of weight that you have to manage. When you raise the tailgate, the springs, which extended as the gate lowered, will begin to retract, thus helping to pull the tailgate back into the upright position, again limiting the weight that you are responsible for lifting. As you raise and lower your tailgate, the self-lubricating thermoplastic rollers help to guide the cables in and out. This controls the movement of the cables for smooth and steady operation of the assist, and it also reduces wear on the cables.
Great product, I should have bought this years ago. I installed it on a 6 1/2 x 12' trailer. I'm using 1 spring on the left and 2 springs on the right for the correct balance. I did have to get longer bolts for the round bar. The videos on site are great.
These are great for lifting the gate on my mow trailer the only downside is that the plastic coating on the cables is starting to crack and peal off other than that they are awesome should have done it years ago

The lifts have been working great so easy to close the gate on my trailer the only problem is that the cables are peeling the protective coating off of them
I had seen a couple of these installed on work trailers and inquired about the owner satisfaction, which was extremely positive. My only apprehension was the installation, but the instructions were fairly clear. The hardware is high quality. Since installed I find I could not live without the Gorilla assist. The lift assist system has been 100% dependable and has performed beyond my satisfaction.

After a year my Gorilla assist works perfectly.
Easy install and they work as advertised. Makes putting the tail gate ramp up or down a lot easier.

The Gorilla-Lift lift supports are fantastic. Without them I do not believe I would be able to lift the gate at my age.
Easy Install - Easy to lift now!!
The gate was extremely heavy PJ TRAILER -U8 model gate
I can now lift with one hand — very little effort
THANKYOU!!

This was definitely the answer to no strain on my back, or needing help to lift the gate anymore. This is without a doubt an item everyone should have for those heavy lift gates. So Satisfied!!!
I LOVE this thing!!! I'm always loading and unloading items from the trailer by myself and the gorilla lift makes it so easy!!! It's definitely the best money I have spent in a long time.

I really LOVE this thing!!! I will ALWAYS have one of these on any trailer I purchase in the future!
We have owned our Gorilla Lift for a year now and absolutely love it!! It was a two person job to install. It makes lifting the heavy ramp a breeze to do with just one hand. We painted the bold yellow square bars black to match our trailer. I would definitely purchase the Gorilla Lift again if we get another Doolittle trailer.
This is a modified tailgate, heavier than normal, works great, followed instructions got longer bolts for tube rails, easy, I will get a set for my 7x20 landscaper

George, nice to hear from you. It's cool to hear that the lift assist works with a heavier tailgate. Other customers will appreciate that feedback. Are you all geared up for summer?

Should have purchased this years ago. What a difference. I had to do a custom mount on the side of the trailer rails due to the location of my gate latches. Welded on 6 pcs of channel iron, drilled the holes and mounted. This allows you to use the tie downs on the top of the trailer rails and let's the cables stay online with the rollers with no side load. It now takes very little effort to raised and lower the 6'4" x 4'2" gate made with 2" angle iron. Could have gotten away with just one but two makes the gate super easy. The force needed to raise the gate from the ground now measures between 5 & 6 lbs. Product was as advertised and shipping was super quick and free.

A year later and this thing is great ! Trailers should come stock with these things. Should have bought it sooner.
Because of the trailer I had to modify the position of the spring mounts. I had to buy Extension Roller Assemblies for Gorilla-Lift Trailer Tailgate Lift Assis plus buy 2 - 6in bolts for the tailgate cable attachment as the supplied bolt were not long enough. After I made the modifications it works fine.
I have been wanting this lift for some time and so glad I ordered it from etrailer.com. They had the best price around, quick shipping and customer service is awesome. Total installation time was around 1 hour and easy to do. I have arm, neck and back issues so the trailer ramp was difficult for me to raise and lower. The Gorilla Lift made it so easy to use now, I can't believe I wanted this long to get it! Highly recommend this company and the product!

This gate lift is fantastic! One year in use and still works like a charm. No problems or issues in the last year nor do I anticipate any. Quality is 100 and this product has exceeded my expectations. Highly Recommend!
I installed the Gorilla Lifts to my trailer following the directions included in the box.
The direction were easy to understand and follow. The lifts were easy to install, adjust and work great. The ramp on my utility trailer was heavy and hard to lift by one person. It is an easy, one handed operation now. I am very happy with the lifts and the service I receive from etrailer.com

The Gorilla Lifts I purchased from etrailer.com and installed on my carry-all trailer are fantastic. They have raked the strain off my back when raising and lowering the tall tailgateramp. I recommend them to everyone who has a similar style trailer!
Even my 84 year old mother-in-law can easily lower and raise the ramp now! In the process of doing some rehab on this trailer and having the gorilla lift will help with ongoing usability. You can see how it is holding the weight of the gate! Take care in determining your mounting spot where the cables attach. I used ratchet straps to get the cable ends (under tension) over the bolts in the gate.

This lift gate assist is still used all the time on my trailer, as I move my zero turn or take it to the shop. I am still happy every time I softly open the gate without slamming it down on the driveway, or easily lift it and secure it for travel. I had not thought of the slow opening aspect when I purchased this, but find it great in not damaging driveways and parking lots.
My trailer had a heavy back braking tailgate/ramp. I installed one side and it was enough lift to allow anyone to operate the tailgate. I installed the other side cause I don't have a second trailer to use it on. With both on, the ramp has almost no weight to it. It's a simple straight forward product that works great. Quality is well worth the price. My installation was slightly more difficult due to the trailer having extended sides. I had to use a piece of flatbar to offset the yellow tubes slightly. I included a pic and you can see the offset bracket if you look closely.
The Gorilla-Lift was installed on my almost forty year old utility trailer that I have recently dove tailed, painted and new wood. The tail gate is 5’ x5’ made of 2” tubing and expanding metal (heavier thanI wanted to lift). You can see by the pictures all it took was one lift with the larger spring to do the job. Was adjusted to where you take your hand off it stays put. The Gorilla- Lift was recommended by a friend that has one installed on a much heavier tail gate
that works great.
I would recommend the Gorilla-Lift to my friends.
I could never go back to life without the Gorilla tailgate lift assist. It was tricky installing on a 15 year old 12 ft. PJ's single axle trailer due to structural side rail supports that just happened to foul the locations where the bolt holes were needed.
We worked around the problem but even with that frustration I love my lift assist and my back loves it even more so.
Made the ramp on my trailer 5' long and extra heavy, could not pick it up, ordered a set of Gorilla-lift trailer tailgate lift assists what a difference they made! Great product, easy to install I would recommend this product to anyone building or purchasing a trailer with a tailgate will save your back.
I've had two back surgeries so I was very hopeful these would help with raising and lowering a heavy tractor ramp on my new trailer. They have exceeded my expectations.. I can literally use one hand to raise and lower the ramp... I would like to offer a install tip.. use a adjustable wood clamp to align the two tubes when tightening the bolts and they will be perfectly aligned. Great product.

Great... bought s second one for my lawnmower trailer !
Easy to install, took less than 2 hours, and part of that time was looking for an 1/2 drill bit. My wife can open and close the tailgate easily.

love it, just use my foot to lift it back up
Makes lifting the tailgate ramp on my trailer so much easier. This is such a great product and I highly recommend it for anybody with a trailer With a liftgate ramp especially if you have back problems or want to avoid back injuries.
We wish we'd bought this years ago. I do a lot of the mowing and handling the trailer ramp/tailgate is hard on my back and shoulder. I decided to buy from someone besides the big online retailers and ETRAILER'S price was comparable. I like the ease of ETRAILER'S website and appreciated the video on the installation. We did the install in about 1 1/2 hours. Looking forward to using the gorilla lift!
Wow! What a difference these make when lifting a heavy trailer gate. I wish I would've put these on years ago. I used to worry about hurting my back every time I lifted my 6 foot tall steel ramp gate, now I just give it a little nudge with the toe of my foot and it comes right up to my hands.
So easy!!!
Great product...
I have a utility trailer with a bi-fold gate that was too heavy to operate and the use of the Gorilla 1 helped with the ease of use. I had to make a cable guide that was mounted in the box tubing of the first section of the bi-fold gate and the cable end was attached about 4 inches from the hinge of the second gate. This allowed assistance in the weight of second section of the gate as was lifted to lower the first section of the gate.
From the lowered position, the cable tension allowed the weight balance of the full gate to retract with ease and automatically fold.
The Gorilla lift works great. My tailgate was impossible to lift by myself, but now one hand does it easily. I needed to be creative to mount it on the outside of the top plate due to the rear post, but a piece of angle iron did the trick.
bought as a gift for a friend. I had purchased one a few months back and it has been worth every penny. Had to make a few modifications. Had to buy bolts as my trailer has 2x3 square tubing as opposed to 2x2. Also, one of the predrill holes lined with my fender. Great item.
