Do you have a question about this Trailer Ramp Spring?
  • Recommended Garage Door Spring for a 5' Wide Trailer Door
    Hey Michael! I would be happy to help you with the spring assist but we do not have a ramp door for you. I've got a couple options for springs depending on the weight of the door/ramp you choose to go with. These come with all mounting hardware necessary to get them set up. I have listed them below: 80 lbs Capacity - Conventional Ramp Door Spring item # M384FR 120 lbs Capacity - Conventional Ramp Door Spring item # 362SA6

  • Difference Between Conventional Ramp Door Spring for 6' Wide Enclosed Trailer # M364FR and M384FR
    The Conventional Ramp Door Spring for 6' Wide Enclosed Trailer # M364FR has two spools that cables can attach to which gives a bit more flexibility in how it can be used whereas the # M384FR only has a single spool. I attached review videos for both for you to check out as well.

  • Overhead Ramp Spring for Use with 80 Lb Trailer Ramp
    If the weight you would be lifting is the weight of 80 lbs then yes you'd only need the part # M384FR to help lift it. This would have enough capacity and could be wound to basically make the ramp feel like its very light.

  • Replacement Ramp Door Spring Assembly for a Cargo Trailer Ramp Door
    The spring assemblies are pretty universal and can be cut to length depending on what size you need. The Conventional Ramp Door Spring for 7' Wide Enclosed Trailer - Dual Spring - 120-lb Capacity item # ERS120D81 will work for your Carry-On 6X12CGR7K. You will have to shorten the bar to get it down to the 66" wide you require. If you don't have experience working with torsion springs I recommend you contact a garage door installer. Each spring has to be wound a quarter turn at a time 30-40...

  • Are Trailer Ramp Door Torsion Springs Available as Separate Items
    Unfortunately, we don't offer the torsion springs as an individual item. I'd recommend the # M384FR 6-foot spirng assembly which includes the shaft, drums, cable and all the needed hardware for installation. Keep in mind, those torsion springs are wound up with an incredible amount of force so for the sake of safety you'll want a professional to handle the installation for you. I can remember helping a friend to install a similar spring on a garage door years ago. He was using a screwdriver...
