  • Choosing/Sizing the Correct Trailer Ramp Spring for a Ramp Door
    When selecting ramp springs for a trailer ramp, you will want to know the diameter of your hinge pin and how much space you have available in the hinge. A typical horse trailer or utility trailer ramp uses 3/4 inch hinge pins and would require two ramp springs with a 3/4 inch inner diameter. The ramp springs that we carry fit 1-1/2 inch diameter hinge pins and are designed for use with heavy-duty steel ramps like those on equipment trailers or car haulers. The spring slips over the hinge...

    Hey Rodney! Congrats on your new trailer! If you door weighs 250 lbs or less the Conventional Ramp Door Spring for 8' Wide Enclosed Trailer item # CB250D96SHD will perfectly. You'll just need to trim the shaft down to fit your trailer's inner width. It can be trimmed down to 6-2/3'. I have no idea how heavy your door is but this is our highest capacity ramp door spring. I have linked a review video below so you can see the functions of this spring demonstrated. What specific model trailer...

  • Will the Gorilla-Lift Utility Trailer Tailgate Assist Wpork With an Enclosed Trailer
    Unfortunately the Gorilla-Lift Utility Trailer Tailgate Lift Assist w/ Cable # GL1 you're looking at is only going to work with on utility trailer with raised bed rails, so it's not going to work with your CarMate enclosed trailer. Instead, you'd need to use a conventional spring like the Conventional Ramp Door Spring for 8' Wide Enclosed Trailer # CB250D96SHD which will work with enclosed trailers. You're just going to need to measure the distance between the mounting brackets and let...

  • 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 actual...

  • Recommended Ramp Spring for Toy Hauler Ramp
    We have ramp springs that would work well for you, but the springs part # GSCC-400 are not intended for what you are looking to do. Typically for toy haulers ramp springs like the part # CB250D96SHD are what we recommend. This installs above the rear door frame and allows it to easily be lifted. The installation instructions for this product are recommended for individuals who have experience winding torsion springs. If you have not worked with a torsion spring system before, we recommend...

  • How To Choose Correct Ramp Door Spring for a Nitro Toy Hauler Trailer
    The Conventional Ramp Door Spring part # CB250D96SHD is designed for a trailer door measuring 80" to 96" wide with a hinged weight up to 250 lbs. In order to confirm fit, you'll first need to measure your door end to end. Then, you'll need to find the hinged weight which is calculated by placing a scale on the ground in the center of the landing path of the door edge (no cables attached). If the weight is between 230-250 lbs per se then this would be a great option for you. If you have...

  • Would Enclosed Trailer Ramp Spring # CB250D96SHD Be Rated High Enough for 92 x 74 inch Ramp
    The Enclosed Trailer Ramp Heavy Duty Spring - Dual, 96" Wide # CB250D96SHD is rated for doors up to 250 lbs. I'm confident your ramp won't weigh more than that unless you've added weight to it beyond the decking.

  • How To Measure For Replacement Overhead Springs On A Trailer Door
    In order to measure the size of spring # CB250D96SHD your trailer ramp door needs, you'll want to take these measurements: Measure the springing weight, you can do this by taking down the weight of the ramp at the beginning of the spring cycle. This can be done by weighing the trailer door by placing a scale underneath the door with the spring assembly not attached. Next, you'll want to measure the distance from the top of the door to the end of the open door. This is a safety precaution...

  • Choosing the Correct Ramp Springs for Enclosed Cargo Trailer
    The springs you mentioned are designed for use on ramps that you'd typically see on a heavy equipment trailer. They're way too stiff to be used on a trailer door. The correct springs for your application will depend on what you are using the ramp for and the width of the trailer. The Ramp Springs you are asking about are best used for heavyweight steel doors on a horse trailer or for an enclosed car trailer. If one man can lift the ramp, a more lightweight option like a torsion spring...

  • How to Determine Required Capacity of Trailer Ramp Torsion Spring
    On a hinged trailer ramp the hinges will carry a varying portion of the ramp weight depending on the ramp's position. When fully opened/extended the torsion spring will actually be holding more of the ramp's weight that when it is almost fully raised. In the fully vertical position more of the ramp weight is on the hinges since the ramp will be more directly over them. The M-3 Enclosed Trailer Ramp Spring # CB250D96SHD can lift 250-lbs of ramp weight. You can use a scale to weigh your...

  • Recommended Ramp Door Spring Assist For A 8 Foot Trailer
    When installing a spring assist on your 8.5 foot wide trailer I recommend The Conventional Ramp Door Spring for 8 foot Wide Enclosed Trailer - Dual Spring - 250-lb Capacity # CB250D96SHD. This will work for you 8-1/2 foot because of where the springs actually mount. This dual-spring setup lets you easily open and close the ramp door on your enclosed trailer and eliminates the risk of it freefalling. It will fit trailer doors between 80 inches to 96 inches wide.

  • How are the Torsion Ramp Springs Weight Capacities Rated
    The weight capacity of the Enclosed Trailer Ramp Spring # CB250D96SHD that you referenced is the capacity of the spring as a whole. It wouldn't be listed as total ramp weight since the length of the ramp and hinge used would end up making that number hard to pin down. This assembly is rated for up to 250 lbs capacity.

  • Overhead Door Springs On Enclosed Trailer Frequently Breaking
    With your over head garage door springs frequently breaking you may not have the correct capacity springs for your door. We have kits that range from 80LBS # M374FR up to 250LBS # CB250D96SHD. The weight rating is not the door weight but the amount of force required to raise the door at any given point. The easiest way to check this is with a scale while raising the door. If you can tell me the weight you are seeing on a scale I can help find the correct system for your door. The Ramp...

  • How To Choose the Correct Dual Ramp Door Spring for an Enclosed Trailer

For example, the Enclosed Trailer Ramp Heavy Duty Spring part # CB250D96SHD has mounting brackets that can be adjusted to sit 80" - 96" apart.

  • Recommended Ramp Door Spring for a Spring with 82.5" Mounting Brackets and 89.75" Wheel Width
    We have a good solution but the Conventional Ramp Door Spring for 8' Wide Enclosed Trailer part # 362SA8HD does not have quite enough adjustment for you to be bale to make it work. It will only get down to 94-3/8". Instead the Conventional Ramp Door Spring for 8' Wide Enclosed Trailer part # CB250D96SHD is the way to go. This model can be adjusted all the way down to 80" which will work out really well with your setup.

  • Ramp Door Spring for a 200 Pound 8 Foot by 8 Foot Toy Hauler Ramp Door
    I do have a solution for you but the Rack'Em Double Barrel # RA-27C is only for open utility trailers. For a toy hauler ramp door you will need # CB250D96SHD. This is similar to the spring system on a garage door. This spring has a 250 pound capacity so it will take up most of the weight of your ramp door. Keep in mind that these types of springs need to be professionally installed such as by a garage door company. Working with high tension springs can be dangerous and this is best left...

  • Trailer Ramp Door Is Hard to Open and Close, Do the Torsion Springs Need to Be Replaced
    It could be that the springs are worn out and need to be replaced with either new springs or a new system such as # CB250D96SHD. Inspecting, working on, and/or installing these systems is not something you would want to do yourself because they can be dangerous (the springs are under a lot of tension). I recommend having a garage door company take a look at it to determine if anything can be done to fix the existing system or if a new system is needed.
