• 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.

• Will Conventional Ramp Door Spring M394FR Work On Toy Hauler Door?
  Hello Robert, thanks for reaching out. Yes, a Conventional Ramp Door Spring like part # M394FR can work on toy hauler doors and will make it feel a lot lighter than it is now.

• 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.

• Looking For Overhead Spring Assist For Son Pro Snowmobile Trailer
  Hello Chad, thanks for reaching out. Adding a conventional ramp door spring system will definitely help when raising and lowering your ramp door. I definitely recommend doing with a dual spring for maximum support. You will just want to measure your door and make sure it is 8" wide. Also it helps to get an idea of the door weight. The # M394FR spring has a 185 lb capacity so we do want to be sure your door does not exceed this. With it being aluminum I highly doubt it weighs more than 185...

• 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.

• 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...

• 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.
