Most excellent. Still works like brand new!



by:

After destroying my single door spring I opted for this dual spring setup due to the door always being heavy to raise.
Wow what a difference! 3 turns on each spring and I can easily lift the cargo door with 1 hand (fingers).
etrailer always comes through when you need them. Fast shipping and a great product.
Door spring installed on a Mission 22ft 4 place deck over sled trailer.

We have a enclosed snowmobile trailer that was always difficult to open. Not now the new set up works great. Thank you for having a great product.



by:

Works great I did beef up the support and added a center support and bearing. Probably would have been fine as it was but I’m an over do’er.



by:

ive installed many ramp doot assemblies. the new brackets are much easier to install by myself. most times i would need a 2nd person. keep up with making things easier and better



by:

We received our door spring and the drums were damaged. I called etrailer and they sent new ones out quickly so we could get our trailer door fixed right away. They were most excellent in customer service :)



by:

The service is fantastic all the time!

The M394FR ramp spring I purchased a year ago has been working great. It was easy to install and out performs the original spring on my 24’ car hauler trailer.



by:

Everything worked out great. Installed on a snowmobile trailer. The door originally only had a spring system on the bottom of the door. It took 2 people to close. After installing the M394FR it is a 1 arm operation. Highly recommend this product

  • Replacement Spring And Hinge Options For A 2008 Jayco Recon ZX 37U Toy Hauler Ramp Door
    Our ramp door hinge selection is limited to just part # PLR1902, which can be welded in place. As for the springs, we have a bit of a selection that you can narrow down depending on the width of the ramp door and the capacity needed. For example, part # M394FR can fit a door width of 67-3/4" to 95-1/2" and has a spring capacity of 185lbs. I've attached a link below to our spring options.

  • Availability of Dual Spring Ramp Door Spring that is 8 Foot Wide
    We have an 8 foot ramp door spring that has dual torsion springs like you asked about with the part # M394FR. This is the hand wound torsion style spring you mentioned.

  • Ramp Spring Recommendation for 8 Foot Wide Trailer Ramp
    I would think the 185 lb spring would work best like the part # M394FR that you referenced. 185 lbs would feel really hard to pick up off the ground so I would assume this would be right at the correct capacity to make sure your ramp is easy to pick up.

  • Ramp Door Spring Recommendation for 200 lb 90" Wide Door
    Hey Rick, thanks for reaching out! I'm guessing the 90" dimension is the width of your trailer door so for your application I recommend the Conventional Ramp Door Spring # M394FR because it has a 185 lb weight rating. This means that you'll still need to put a little effort into lifting the door, but you'll only be handling 15 lbs of it if your door really does weigh 200 lbs. We have some higher rated springs but that can be dangerous since the spring can close the door by itself if it's...

  • What Info Is Needed to Pick Out Conventional Trailer Ramp Spring
    Hey Scott you will need to get the width of your ramp as well as the weight of the ramp to pick out what you'd need. For example the part # M394FR is for 8 foot wide ramps and has a weight capacity of 185 lb. I attached a link to all of the options we have if that is not what you need.

  • Is Trailer Ramp Spring Adjustable in Tension
    The spring capacity of the torsion style ramps springs like the part # M394FR that you mentioned is how much lifting strength it is capable of if adjusted for it. This spring has a 185 lb capacity but could have a lower tension used if that's too much for the door. Since we recommend having a pro with experience winding garage door springs install these they'd be able to set the best amount of tension to use.

  • Will the Conventional Ramp Door Spring Fit My Door with Brackets 81 Inches Apart
    Yes. The Conventional Ramp Door Spring for 8' Wide Enclosed Trailer # M394FR fits 67-3/4" to 95" wide trailer doors. Your door with the brackets 81" apart falls in this range, so this spring will work well for you.

  • Which Way Should the Cable Wind on the Hub?
    The cable for the Conventional Ramp Door Spring # M394FR needs to always come off the bottom of the drum. If it comes over the top, the system is installed backwards. It should be noted that it is recommended that only individuals who have experience winding torsion springs install this product. If you have not worked with a torsion spring system before, we recommend contacting a local garage door company to install this system.

  • Height of Mounting Brackets of Conventional Ramp Door Spring for 8' Wide Enclosed Trailer M394FR
    I was able to get the height for you of the mounting brackets for the Conventional Ramp Door Spring for 8' Wide Enclosed Trailer # M394FR. Overall, the height is 6-1/4 inches, and from the top of the opening where the spring's shaft goes through to the top of the bracket measures 3-7/8 inches. You won't need quite that much space above the drum, but will want at least 2 to 2-1/2 inches to be able to mount the bracket. I have added a link below to a video review for you to check out as...

  • Choosing the Correct Replacement Spring for an Enclosed Trailer Ramp Door
    I'd go with a double spring personally, Scott. These are typically going to be used on more heavy duty applications like your enclosed trailer with a pretty heavy door. In order to get a proper replacement though, you'd need measure the width of your door and find out the weight of the door at it's heaviest point, which I'd imagine isn't more than 185 lbs, so something like # M394FR should work great but I recommend verifying yourself.

  • How Do the Cables Get Mounted To the Doors On the Conventional Ramp Door Springs
    The cables with the Conventional Ramp Door Springs like part # M394FR are attached to the door via anchor brackets which are included with the kit. I have attached below the excerpt from the install instructions below which goes over the cable attachment. I have also pointed them out in a photo as well. "With the door in the down position, attach the cables to the anchor brackets mounted on the floor of the door by inserting the clevis pin through the anchor bracket and the round thimble...

    Image 1 for
  • Are Trailer Ramp Door Spring Dual Spring Twice Capacity as Single Spring
    Hey Rene, so the ramp door springs like the part # M394FR are not all identical in spec and capacity. So what that means is a double spring setup does not mean it's just the same spring on both ends compared to a single spring. This is why the capacities do not just double compared to a single spring.
