Conventional Ramp Door Spring for 8' Wide Enclosed Trailer - Dual Spring - 160-lb Capacity

by: MN Rider06/01/2023

I am happy with door springs and they were easy to install. I installed them on my snowmobile trailer which had a heavy door that I struggled with every time. Now with one hand and little effort the door is easy to close and and open. I would give this a 5 star but the screws holding the pulley tight on the bar keep slipping which means making an adjustments several times a year.1591032

First, shipping was really fast. After I ordered I received a email saying my order had already shipped. I ordered on a Tuesday and was able to install my equipment during the weekend. I have a smaller 6 x 10 trailer and I only utilized 1 torsion spring which gave me a back up spring for reserve. After installing the unit with new tension cables my ramp door works smooth and I’m really happy to have my trailer back in service again. etrailer understands the importance of getting customers product out as soon as possible. I thank you for your professionalism and will recommend your company in the future.628729

Thanks so much Ashley for the great job you did getting that product out during the Christmas season. I did the installation today ,I just finished it. All I can say is if you can follow directions and read it's very easy to install. I found the product to be as good as the OEM. I will attach pictures to show you installation, and so that you can rest your little mind that I included the safety straps and closed . Thanks again for your help. 328639

Great price and fast shipping. Packaged well and has everything you need besides the wrenches rods to wind spring. Very easy to install. Since I had been brackets already it took me about 45 minutes including taking the old one off. And I already had the rods to wind spring up which is a must. Thanks. 381769

I've installed about five door springs so I have the process down. it's good to leave extra pipe when you cut it down to size. This leaves wiggle room for additional adjustment.

You need to watch the cable angle when the door is closed. It should be as close to perpendicular the wheel as possible. If there is much angle it can rub on the ribs on the winding wheel and damage the cable. My new trailer from Cargo Mate/Continental was improperly installed and they cut the pipe too short. I could not adjust the cable angle and it ate the cable.

Check the cable with the door open as well to insure it's not too close to the door opening where it can rub. The Cargo Mate/Continental trailers have the ramp cable mounting tab constructed really far outward.

This is really not ideal for the way spring kits are designed. It really should be inwards about 1/2" more. This causes you to really need to do an installation with perfect leeway or the cable will have too much would angle when the door is closed or it will rub on the ramp opening when the ramp is down.

I find using a pair of Vice Grips is handy for getting the cable winding pulleys wound tightly to avoid having any slack when the door is closed. If you have any slack the cable can bind up and ruin the cable.

I used two old wheel barrow axles to make winding rods. No place I know of will sell the winding rods. When winding the springs stand to the side of the rods so if something goes wrong you are not in the path of where a rod could be thrown.

My door closer called for winding ten times but nine actually worked perfectly. Ten spins of the spring caused the ramp door to float some. The dual spring sets up are much better because if one spring breaks the other will prevent the heavy ramp from free falling.

Periodically check the cable when the door is closed for stretch. If the ramp is down on uneven ground and something heavy is loaded it can cause one cable to become out of adjustment where it needs to be tightened.396650

Great, I already have posted a review so I wont add more about the product or install. I will say that you need to be aware that the mounting points on the ramp MUST be set inward at least 1/2. Im not sure what specs are in the directions. One of my trailers is a a Forest River trailer and they did not correctly mount the ramp cable mounts in the correct spot. These trailers go by the names Continental Cargo and Cargo Mate out of the Waco TX plant. If you own one of these trailers the cables may rub on the door opening and cause cables to break. I do not recommend buying any Forest River trailers for this and many other reasons.

The spring kit was installed without any problems. It is a quality product. No problems after about a year's time in use.1552137

Recently purchased this trailer ramp dual spring to replace my single spring. The original spring roller from factory snapped. Cut to fit it to 75 inches. Perfect replacement. Instructions very detailed and right on. Install time with spring adjustments 1 hour. Delivery was fast and product was priced competitively. Very happy. And dual springs just make more sense.257503

After a year of wear and tear, working perfectly. Remember oil the springs at least monthly

I have had swell results with etrailer. I am always confused why the customer satisfaction survey comes so soon. The spring is still in the box and had just arrived 3 hrs before the email to review it. I have to say the packaging is wonderful and hope the product is as good521620

I am happy with the way my door ramp works. I think I should take another turn on the springs to relieve more weight. I had a medical situation and have not gotten to it but the springs have plenty of lift left in them. Sure am happy with etrailer and will continue to shop with them for my towing needs

Complete kit, no alterations or additional parts needed. Totally bolted into existing structure. Will use e-trailer again in the future.1496858

I installed the dual spring assist for my ramp door and I am very pleased as I have a bad back and was wondering how much longer I would be able to keep hauling my collector car. I live in a remote forest area and can't drive it without destroying all the work I have done to it.
My trailer is older but it works well for me.
Now I plan on updating the brakes and hubs next.
I updated the lights with LED's and suggest everyone to do the same.
Thanks, Don Parry442461

The ramp door on our toyhauler was so extremely heavy to lift or lower. We removed the coil springs mounted at the hinges and install this lift system. Now my 7 year old grandson can raise and lower the door. It took about 2 hours to install.302961

Great product. Awesome price and accurately described. Used this to replace a spring in my car hauler that had lost one of the cables. Door opens smoothly and installation was a breeze. 453863

Still doing great after a year!! I cant believe the difference it makes in leveling out the door and making it easier to open. I use the on a car hauler, which we use to store our summer toys. But we have used it several times to actually haul cars and the springs have held up perfectly!

I didn't realize how much tension my old spring had lost until I installed this new one. My ramp door is heavier than most because I had to add a 2' flap for my 10' long custom. It was a strain to raise my ramp door before, but now I can raise it with one hand and have to hold onto the handle to keep it from slamming shut. After 1 year, it still as strong as when installed. This is a top quality spring and the included instructions made installation easy. I would and have recommended this spring to friends .369464

Good product. Well packaged. Arrived very quickly. But came missing the hardware set. After a little back and forth with etrailer I was sent the missing hardware at no charge. They took care of the problem and for that I commend etrailer. The 5 Stars here are for how well etailer handled this issue. I would have demoted M-3 (the manufacturer) for mispacking the set, but that's not the fault of the seller. Thanks etrailer for good customer service.310145

Bought a year ago installed on a trailer I made myself. works flawlessly.. I was worried because one of my buddies has a brand new trailer and his wires are always popping off his springs I have never had an issue and I use my trailer door 7-8 times daily through the summer. Could not be happier with this product467738

The product was great. I up grated my enclosed trailer ramp spring with this dual spring. Now it don't take2 people to put the ramp up. I am so happy!! Shipping was fast and accurate. I will be back for more parts.234634

Ordered a new pulley system for the trailer door. Arrived, in perfect condition and on time, actually a little earlier than I expected. Price was best price I could find and the part is a good quality part. Very Very Happy with this purchase and the whole experience. Will advise family and friends about etrailer for any of their trailer needs. Also, all the folks I spoke to were knowledgeable, helpful, and genuinely nice.
Thanks for the part, quickly. You have definitely won my business for any trailer parts needs.397463

Absolutely best spring replacement you can buy. Very easy to install. Just make sure you’re careful when using the extension bar for tightening. Still working great after one year and weekly use.931542

Constantly happy with etrailer. I purchase many products a year from them for a small fleet of enclosed landscaping trailers. Recently had a door spring assembly fail and had a new one dropped off today (2 days earlier than expected and quoted by the website) Now I can get the trailer back up and running by Monday!460738

I've used various trailer locks over the years. But this Master lock is the best that I have ever used.
Easy, secure, and gives you a better comfort level.681785

I needed this part for one of my maintenance crew trailers that runs daily. I was very impressed with how quick I received the new spring assembly, and so were my guys that had to lift the heavy door for a few days. The installation and instructions were easy to follow and the price was very reasonable. I now have a company to go to for all of my trailer needs. Thank you etrailer.com !429786

Great product. installed in 1 1/2 hrs. Made a 70lb door lift itself with one hand. Ordering and shipping was great. Even a follow up email on the product. Definately would recommend product and etrailer Denis from Hudson nh310083
