Expert Answers about Trailer Ramp Springs


  • Ramp Spring For Rear Door of 2015 Forest River Vengeance 5th Wheel Toy Hauler
  • We do offer a ramp spring that would work for you. According to my research, your Forest River Vengeance Toy hauler is about 8-1/2 feet wide, which means that you'd need an 8 foot spring. The exact spring needed would depend on exactly how heavy the door is. We offer a 250 lb spring as part # CB250D96SHD, a 230 lb spring as part #362SA8HD, a 150 lb spring as part # 362SW81 or a 120 lb spring as part # M354FR. Ideally, you'd want to choose a spring with a capacity a bit less than the...

  • Ramp Assist for Heavy Ramps on Trailer
  • For your 35 ft flatbed trailer I recommend the Redline Ramp Spring # RS16933LH for the left hand side, and # RS16933RH for the right hand side. These are designed to help lift the ramps on heavier trailers like yours. So long as the hinge pin is 1 1/2" diameter these will work great. They have a 2K lbs tension rating, so as you lift it takes some of the weight off. If your ramps are extremely heavy, you can use more than one on each ramp. I linked the parts mentioned above and a...

  • Horse Trailer Ramp Spring For Helping Lift Heavy Ramp
  • What's the diameter of the shaft where your current springs are installed? If they are 1-1/2 inches you could install the part # RS16933LH and # RS16933RH instead of what you have now and you'd have a much more powerful spring. But if the shaft is smaller than that we won't have anything we can recommend.

  • Ramp Spring Recommendation for 2022 Thor Toy Hauler
  • Are you wanting to do a torsion style spring that fits above the door like most toy haulers? Do you know how wide the door is and about how heavy the door is?

  • Double Ramp Spring for 6 Foot Ramp Door on Enclosed Trailer
  • We sure do! For your 6 foot ramp door, you'll want to use part # 362SW61. This unit uses self-winding springs which means that the average do-it-yourselfer can install the system without needing a professional install. Regular torsion springs need to be wound by had, which is very dangerous if you're not familiar with such installations. The self-winding springs remove that worry. I've linked to a video showing a typical install.

  • Measuring Ramp Door Weight For Replacement Ramp Door Spring
  • In order to properly weigh your door to figure out the correct spring you only need to find the weight when the ramp door is down. Assuming you weighed your door without spring assist, you can use the 74 lb measurement. Typically, you use a scale and place a block of wood or something similar on the scale and rest your ramp on the block to get this measurement. You do not need to know or estimate the total weight of the door to choose a replacement spring. Based on the weight and the...

  • How to Choose Proper Trailer Ramp Door Spring Rating
  • You won't need to obtain the weight of the entire door, just the un-hinged side. You'll want to find the amount of weight you'll need to overcome to easily lift the door. You could use an old bathroom scale, place some blocking on it, and rest the open side of the ramp on it. The weight you get, minus the weight of the blocking would be the amount of weight that the spring needs to overcome. For instance, the # 362SA8207 ramp spring you'd looked at has a 150 lb rating. If the spring rating...

  • Does Conventional Ramp Door Spring 362SA6 Include The Mounting Brackets?
  • The Conventional Ramp Door Spring for 6' Wide Enclosed Trailer # 362SA6 actually does include the mounting brackets, just not the mounting hardware.

If you are not familiar with installing torsion springs then you will need to have a professional install this for you. I included a video of the # 362SA6 for you to take a look at.

  • For the rear opening I recommend using enclosed trailer ramp spring # ERS120D81. It has a capacity of 120 pounds. And for the rear I recommend # 362SA6 which has a 120 pound capacity. Professional installation by someone with torsion spring installation (like a garage door company) is recommended because working with these types of springs can be dangerous.
