The Raynor Company Self-Winding Ramp Door Spring Installed

Conventional trailer ramp door springs can be very dangerous to install. For those who don't have experience winding torsion springs, it's recommended that you hire a professional to install them. However, that's not the case with this self-winding ramp door spring.


Conventional springs often require 30 or more quarter-turns with a winding bar to achieve the proper tension during installation. This can cause serious injury if not done correctly, as torsion springs that are wound too tightly can break and snap back with extreme force. Unlike a conventional ramp door spring, this self-winding door spring needs only 3 half-turns and can be rotated by hand, making it safe to install yourself.


Safe, Easy Installation

The Raynor Company Self-Winding Ramp Door Spring L-Bracket

Installation is straightforward. Bolt or weld the included L-shaped brackets above the ramp door frame on each side of the trailer. The notched bracket installs on the driver's side, while the bracket with the hole in the middle installs on the passenger's side.


The Raynor Company Self-Winding Ramp Door Spring Shaft

Lift the spring assembly and slide the ends of the shaft into the brackets. If the shaft is too long for your application, you can slide the cable drum down and cut the passenger's side of the shaft down to a shorter length.


The Raynor Company Self-Winding Ramp Door Spring C-Bracket

Secure the driver's-side end of the shaft with the included C-shaped bracket, which screws into the notched L-shaped bracket with the included flange nuts.


The Raynor Company Self-Winding Ramp Door Spring Cable

Next, mount the cable anchors to your trailer door (hardware sold separately). You can also use your existing cable anchors if you're simply replacing your ramp spring. Attach the cables to the anchors with the included bolt and cotter pin.


The Raynor Company Self-Winding Ramp Door Spring Cable Install

Slide each cable drum to the edge of the door, getting as close as you can without it rubbing against the bracket. Now you can start winding up your cable. Insert the end of the cable into the notch located at the edge of the spring and start winding the cable up, keeping it nice and taut as you go.


The Raynor Company Self-Winding Ramp Door Spring Rotation

Once the cable is completely wound, rotate the spring upward 3 half-turns. While holding the spring, use a wrench to tighten the bolts on the spring, securing it in place. Repeat this process with the spring on the other side, and you're ready to go.

The install was so easy. Was setup easily by hand, no need for those dangerous spring bars. And as advertised we were able to lift our heavy car trailer door with our pinky finger.

My order arrived a day early ,which was great ! The ability to track order was very helpful. As for the self - winding duel spring it installed a lot easier than the old wind up style. I did have to drill new holes for the brackets but it was not a problem. The tutorial video was very helpful.

  • How to Weigh Ramp Door to Know Correct Ramp Spring Capacity
    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. You do not need to remove the door to find this weight. You will need a scale in order to measure the weight, a bathroom scale will do. Place a block of wood or other durable material on the scale and rest the end of your ramp on the block. This will give you the weight of your door. Don't forget to subtract out the weight of the block for a more accurate...

  • Ramp Spring For Rear Door of 2015 Forest River Vengeance 5th Wheel Toy Hauler

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.

    Yes, you could trim down the ends of the Enclosed Trailer Ramp Spring # CB250D96SHD to take it down to 80 inches minimum. If you need anything shorter, then I recommend using the 94 inch # 362SW81 instead to give you a few more inches to play with.
