• 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...

• Recommendations for Converting a Swing Door on a Trailer to a Door Ramp
  
• Converting from a double swing doors to a ramp door can definitely be done, it will require some fabrication and ingenuity on your part. I can help you pick out some of the more important components needed for this, but I will not be able to tell you every step of the way. The first thing you will need is a ramp/door. You will want to measure the opening of the rear of your trailer to get the correct size for the ramp. Without knowing how much weight will be on the ramp it is hard to...

• Replacement Trailer Ramp Springs
  
• We have several hinge pins like # HP412G that I have linked for you, but it sounds like you need actual springs. We have some heavy duty ramp springs like # RS16933RH and # RS16933LH if you happen to have a heavy duty equipment trailer like what they haul tractors and other large equipment on. For an open utility trailer you may be able to use a tailgate assist like # RA-27C. Or for an enclosed trailer we have springs that are similar to garage door systems. I have linked those as well....

• How Do the Heavy Duty Ramp Springs Install on a Trailer and Ramp
  
• Heavy duty ramp springs # RS16933RH and # RS16933LH install on the hinge of the ramp. I have included a picture of what this looks like for you. Not all trailers are exactly the same but this should give you a general idea of how the springs install.

• Ramp Spring Weight Capacity and Left or Right Hand Orientation for a Horse Trailer
  
• The right hand ramp spring, item # RS16933RH, and the left hand spring, item # RS16933LH, are differentiated by paint on the springs from the manufacturer. The springs with green paint on them are right side springs, left side springs are unpainted. Right side springs will go on the right side of a ramp and left hand springs go on the left side of a ramp. Both right and left hand springs deflect in the same direction the designation of right and left has to do with orientation of the stick...

• 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. 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 would be a better option. We...

• How to Make Raising and Lowering a Heavy Trailer Ramp Easier
  
• You wouldn't use a spring like # RS16933LH because it produces 2,000 foot pounds of torque and you would not be able to open the ramp. What I recommend is either the Rack'em Double Barrel tailgate assist, # RA-27C. The Double Barrel will reduce a 134 pound ramp to less than 5 pounds and works in both directions and for ramps up to 200 pounds. I linked a video showing how the Double Barrel installs.

• Dimensions and Lift Capacity of Ramp Spring # RS16933LH
  
• I contacted our representative at Redline about Ramp Spring, part # RS16933LH. He informed me that the overall length of the spring is approximately 10-1/2 Inches and the width of the spring is 3-3/4 Inches. The measurement from each ear to center of spring is about 5-1/4 Inches, and the spring is made to fit over 1-1/2 Inch bar. The metal rod that forms the spring is just under 1/2 Inch in diameter. I used photoshop to show the dimensions of Ramp Spring, part # RS16933LH, (see picture). For...

• Replacement Springs for Ramp Door on Continental Cargo Enclosed Trailer
  
• I believe you're referring to the # RS16933LH spring, is that correct? These springs aren't meant for an enclosed trailer with a ramp door, they're meant for the very heavy steel ramps you'd typically see on the back of a trailer used to haul heavy equipment like bulldozers. Your best bet would be to use a ramp spring like what you're already using, like part # ERS120D81. Installation of springs like these can be extremely dangerous, due to the tension stored in the spring. If you...

• Availability of Enclosed Trailer Hinge Ramp Springs
  
• I do believe we have the springs that you are looking for, but they are not part of a kit. We have a left, # RS16933LH, and a right, # RS16933RH. These springs are for a 1-1/2 inch diameter shaft. They will need to be welded into place with the two arms facing down and flat against the trailer and door surfaces. Each spring is rated for 2,000 pounds torque to help with lifting and lowering ramp doors on trailers.

• Recommended Ramp Door Spring for 6x12 Enclosed Trailer
  
• 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 enclosed 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.

• Recommended Ramp Springs For Heavy Equipment Trailer
  
• The Redline Ramp Spring like part # RS16933RH and part # RS16933LH will help with lifting the ramps you said you are building for your trailer. I would recommend 1 spring for each ramp. These springs are made of steel alloy, these springs provide approximately 90 degrees of deflection and are designed to help lift a ramp with 2,000 pounds of torque.

• Trailer Lift Gate Spring Recommendation for a 120 lb Door
  
• It sounds like you are looking for Ramp Springs, # RS16933LH and # RS16933RH. Made of quality steel alloy, these springs provide approximately 90 degrees of deflection and are designed to help lift a ramp with 2,000 pounds of torque. These would work great for a ramp that weighs 120 lbs. For lift capacity, the spring is rated at 2,000 pounds torque. This does not mean it would lift a 2,000 lb door. Also as a note, right-side springs have green paint on them and left-hand springs are...

• Can a Pace Trailer Ramp Be Adjusted to Open Easier After the Torsion Ramp Spring Cable Breaks
  
• Since your Pace trailer was using an Enclosed Trailer Ramp Spring, like # ERS160D96, if you want the spring to function again you will need to have a qualified professional work on it, one with experience with torsion springs (like a garage door company). Without the cable and spring in good working order, the ramp will never operate as easily as it did before. That is unless you repair the old spring or install a new one. I have included a link to our springs. You may be able to use...

• Ramp Assist Recommendation for Toy Hauler Trailer
  
• The ramp spring that we have that would be the closest to what you have is the part # ERS160D96 that measures 96 inches from end to end and could be trimmed down if necessary. The mounting brackets are 77-1/4 inches apart. 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 contacting a local garage door company to install this system.

• Ramp Lift Springs for a Trailer with a 7 Foot Long and 2 Foot Wide Steel Ramp
  
• If your 7-foot long and 2 foot wide ramp is heavy enough then you would use ramp springs such as # RS16933LH and # RS16933RH. But each of these springs produces 2,000 foot pounds of torque so they may be way too strong for your ramp. If you can tell me how much the ramp weighs I can determine if these springs would be a good fit. Based on the material and size I am willing to say the ramp is probably too light for this type of spring. Another option that could work for you is the trailer...

• Recommended Gate/Ramp Assist and Hinge for Trailer Build
  
• The 2K Torque Ramp Spring # RS16933RH is an industrial strength spring. It is designed for up to 90 degrees of deflection, but most people by hand can cause no deflection at all. It is designed to be used with the LH # RS16933LH, and is for heavy ramps or doors like in the attached photo. I would assume it is too strong for your application based on your wording. You may want to consider a different style spring like the Enclosed Trailer Ramp Spring - Dual Spring, 81" Wide # ERS120D81...

• Left Hand Vs. Right Hand Placement of Ramp Springs on a Trailer Ramp
  
• Right hand side would refer to the passenger side of the trailer and the left hand side would be the driver side. The part # RS16933LH is the left side and the part # RS16933RH is the right hand side. Both of these would work great on a 1-1/2 inch diameter shaft.

• What is Actual Torque Rating for Redline Ramps Springs # RS16933LH and # RS16933RH
  
• The Redline Ramp Spring you referenced, part # RS16933LH, and the matching right-hand spring, part # RS16933RH, are intended primarily for use on equipment trailers, such as those used to transport a skid loader for example, not for utility-type trailers. These springs have an inside coil diameter of approximately 1-1/2-inches (and are intended for a 1-1/2-inch shaft). The wire diameter as measured with a digital caliper is 0.465 inches. I checked the Redline catalog and with my contact...

• Trailer Ramp Springs for a 20 Ton Tandem Axle Trailer
  
• That sounds like a very heavy duty trailer. For heavy duty trailers there are special ramp springs, # RS16933RH for right hand side and # RS16933LH for left hand side. They fit a 1-1/2 inch diameter shaft or hinge pin. We do not have a pin that large. I have included a link to a video review of the springs for you. The other springs we carry are all lighter duty for enclosed consumer trailers and probably would not be strong enough to fit your 20 ton trailer.

• Heavy-Duty Ramp Spring Availability
  
• The only heavy-duty ramp springs that we offer are part # RS16933RH and part # RS16933LH. These springs have 4 inch legs, measured from the coil to the end of the leg, and fit on a 1-1/2 inch shaft. These springs are rated for 2,000 lbs of torque.

• Replacement Trailer Door Ramp Spring Options
  
• We do not carry the spring only for torsion springs on trailer doors. But we do carry the replacement assembly. I have included a link to the options for you to the right. Springs # RS16933LH or # RS16933RH would not work since they are designed for very heavy duty trailer ramps.
