Genuine GORILLA-LIFT 2-Sided Trailer Tailgate Lift Assist

THEY WORK AS STATED ONCE YOU FIGURE OUT A FINAL ADJUSTMENT ON PRESSURE THEY NEED SLIGHTLY LOOSE SO THE GATE STAYS DOWN.. OR THEY WILL LIFT THE GATE ON THEIR OWN..

As far as the Gorilla Lift, installation was easy. My trailer has angle iron top rails, so I bought shorter carriage bolts (my choice-less than $1.00). Yes, the supplied bolts are not 5/16” as claimed on the instructions, they appear to be metric. I also bought square plugs to cover the open end of the tubing, which again was my choice. (cost me $1.00) You have to trim the plugs so they fit due to the hardware inside the square tubing. The instructions I found to be well written and understandable. The hardest part was attaching the cables to the tailgate which took some muscle to install, but I did it by myself. I am very pleased with the Gorilla Lift. My wife was able to easily lower and raise the tailgate. We both have back problems so this should help. I only gave the Gorilla Lift 3 stars because of delivery problems. When I placed the order (on a Friday) delivery was guaranteed for the following Tuesday. When it wasn’t delivered on Tuesday, I contacted the seller and was promised delivery on Wednesday. When it wasn’t delivered on Wednesday, then I was promised that it would be delivered anytime from Thursday to the following Tuesday. The package was delivered on Thursday. The Gorilla Lift was available elsewhere for a few dollars less, but I paid the few dollars extra because of the promised early delivery date. Had I known that it wouldn’t be delivered on the promised day, I would have bought from the cheaper seller.

Best thing I ever done.

Instructions were very clear & I am able to raise and lower the gate with very little effort.

I installed this on my trailer and I can lift the gate with one finger now! Its fairly easy to install, there are a lot of YouTube videos to show you.

I got this for my dad for Father’s Day because he runs a lawn care business. He’s getting older and was having issues with the gait throwing his back out constantly. This thing seriously changed his life. He can not rave higher about it. I’d recommend to anyone who asked!

I have a tilt-gate trailer like the one they picture except it has 2-7/16 OD round tubular top rails, not flat rails. The yellow spring housings come in two pieces to allow a shorter shipping box. You butt them up and then bolt them down, two bolts for each piece of tubing. However, theres nothing to align the two yellow tubes together. Thus flat-bottomed square tubes are precariously sitting on top of round tubular rails. You are instructed to drill oversized holes through the mounting rails. This allows you to reposition the square tubes before tightening them down, but also allows the two tubes to move slightly as they absorb eventual road vibrations. The yellow spring housing tubes can become misaligned after a while. If that happens, the long garage-style springs inside the housing hang up on the misaligned tube edges in the middle and boing as they slip off. They should have welded ears onto the tubes that force the tubes to stay aligned or be hinged so that they are mechanically aligned after installation. Also, be aware that the threaded bolts are all metric. The carriage bolts look like theyre 5/16-18 thread, and say so in the instructions, but they are not. The gate-mounting bolts look like they are 1/2-13, but they are not. The carriage bolts supplied are not long enough to go through my 2-7/16 tubular top rails. I had to purchase eight new galvanized carriage bolts (didnt want them to rust). Thats when I discovered the threads were not SAE. The supplied nuts did not fit properly. One of the great features of this type of trailer is that you can fold the gate forward onto the bed to get it out of the wind for significantly less drag and better mileage. If you employ their permanently-attached cable system and its 6 long metric 1/2 bolts, you can never fold the gate inward -- the bolts make the gate too wide to fit inward. If you look at the pictures, youll see that I rigged up a different system using shorter, custom-cut 1/2-13 threaded rod with locknuts, washers and a hitch pin. This allows me easily to remove the cables and still fold the gate inward on return highway trips when empty or lightly loaded. I now have the best of both worlds: an easy-lifting gate and an inwardly foldable gate. Finally, a word on the springs. Since they have no idea how heavy or large your ramp-gate is, they supply two coaxial springs that are really strong. Two springs, one inside the other for each side, comprise the default setup. This means you have five spring combinations to choose from. 1. Both inner and outer springs on both sides, if your gate is really heavy. 2. Both outer springs (no inner springs) on both sides, if the gate is heavy. 3. One outer spring on one side, both inner/outer springs on the other side if the gate is a bit less heavy. 4. One inner spring on one side, one outer spring on the other side. 5. One inner spring on both sides. You test the gate using various combinations and S hooks until youre happy with the balance. The problem is that to get the springs apart so you can use only the inner spring, you have to cut the outer springs loop and pull the larger outer spring off the pair. This renders the spring almost unusable if you change your mind. Its a bit confusing in print. Weigh your combinations carefully before cutting. Out of the box and per side, you can attach the cable to 1) both springs or 2) the outer, larger spring. You cant attach to the just the smaller, inner spring by itself. Because my gate is fairly light, the combination I needed was a single inner spring on one side and one outer spring on the other side. I cut the large outer spring off with an angle grinder. Youd need a very large bolt cutter, or maybe a hacksaw, to cut the spring. But spring steel is very tough. Dont know if a hacksaw would make it. Anyway, now that the gate is balanced fairly well, its simply a matter of picking it up with my toe and it rises easily into position to be locked off. Very handy indeed.

Love this made lifting my heavy gate lift with ease.

I knew from the installation video I watched prior to purchasing it that the install was not a 5 minute process, but I didnt anticipate the amount of adjustments I would have to make to allow it to release and lift my tailgate properly...oh well, its on and finally working as it should...

The parts are top quality and the fit and finish are great! I found that I had to make some modifications to my trailer before installation that werent expected and that I only needed one lift. Installing two wasnt necessary but it wasnt covered in the instructions. I realize that they cant cover every situation but placement on the rail is critical and MUST be followed. Now that it is all installed and modified, it works like a charm! One finger moves the ramp up or down and it is literally effortless. Great product!
