Double-Eye Spring

Part NumberABC

Note: To ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs.

Leaf springs are an integral part of your trailer suspension system. The double-eye spring is suspended at the ends by hangers that attach to its eye or, in the case of tandem-axle or triple-axle systems, into hangers in the front and rear and an equalizer or equalizers in the center. To determine the type of hangers or hanger kit you need, you must know the specific type of leaf spring you have, as well as your axle diameter and capacity. Depending on the hanger kits used with them, springs can be configured to work for single-, tandem- or triple-axle applications.

Video Transcript for Redline Trailer Suspension PR722 Review

Today we will be reviewing part number PR722, the 3-Leaf Double-Eye Spring for 2,500-lb Axles.When ordering a new spring for your trailer, there are a few things you do need to know first. This spring measures 25 1/4 inches long by 1 3/4 inches wide. You will need to know the springs half-length which is measured from the center of the eye mount to the center of the leaf bolt here in the center of the spring. This spring has a 12 5/8-inch half-length. One final thing you will need to know is the spring height. To get this measurement, you will draw an imaginary line from the center of the eye mount on either side and using that imaginary line, you will measure from the spring surface giving us our height.

In this case is 3 inches. You will notice the two 9/16 mounting bolt holes are lined with a nylon bushing. This bushing helps to prevent metal on metal contact while the spring is installed on the trailer. And that does it for part number PR722, the 3-Leaf Double-Eyed Spring for 2,500-lb axles.

Once again, etrailer was fantastic. Their website had all the information I needed. Before last week I had no idea what a leaf spring system was, all I knew was that whatever that thing was on the bottom of my camper was snapped in two and I needed to fix it. Did some research on, it walked me through how to take the measurements and what I needed to look for. I took the measurements and found the product that fit my camper. As I always do, I shopped around, and once again, etrailers price was the best by far. I placed the order on a Friday morning and received a very nice email that afternoon from etrailer thanking me for being a repeat customer and notifying me they had expedited the shipping of my products and they left the warehouse that same day. Showed up on my porch the following Wednesday. Amazing customer service! I ordered the leaf springs, ubolts, shackles and shackle bots needed to replace the springs on both sides of my camper. When I opened the box, everything I ordered was in there and looking great. They shipped exactly what I needed, when I needed it at a price that couldn't be matched anywhere. Everything looks great, haven't had a chance to get them on the road yet, but I'm sure it will be top notch when I do. Thanks again etrailer! 97447

Delivery was very prompt sooner than expected. The information your site provided was spot on. I was able to find a more durable tire for a trailer we are pushing the tire limits. And increase the spring rating by only 500lb fisrt time I've seen off the shelf springs offered in such finite sizes. Though we load within the limits of our trailers this particular unit is at the top of the load range. The slightly heavier parts give me confidents we'll get where we want to go. Thanks we'll be calling again. 65079

Thanks to, I was able to find out that this is the right spring for my trailer. Where before, my trailer was dangerously bouncy, now it rides as smooth as it should. Also thanks to etrailer's video, I knew exactly how to install it. It was very straightforward, and although it took some elbow grease, it wasn't too difficult in the end. Spring works perfectly, just what I needed. 29717

Nice solid spring. Time will tell how the coating holds up to salt water use. I like that several load ratings are available in this length, so I can easily order and install heavier springs if I put a larger boat on this trailer. 151308

Do you have a question about this Trailer Suspension?

  • Replacement Trailer Double-Eye Leaf Spring 26 Inches Long
  • When taking double-eye spring measurements you will need to make sure the weight is off of the spring you measure. You can do this by either removing the spring or by jacking up the trailer on the side you want to measure. Over time, a spring can also flatten out a bit so that could be why you are seeing different measurements. But we do have a 26 inch long spring measured from the center of one eye to the center of the other eye. It is # PR626 and it has a capacity of 2,250 pounds....

  • Dimensions for Spring Hanger Spacing Using the # APTT3 Triple-Axle Hanger Kit on a Boat Trailer
  • The spring hanger mounting dimensions for the Triple-Axle Trailer Hanger Kit, item # APTT3, are as follows. From the center of the hole in the front hanger, to the center of the hole in the center front hanger, the distance should be 29-1/2 inches. From the center of the hole in the center front hanger, to the center of the hole in the center rear hanger, the distance should be 34 inches. And from the center of the hole in the center rear hanger, to the center of the hole in the rear...

  • Replacement Trailer Leaf Springs for a 1999 Thor Skamper Vision Pop-up Camper Model 23L
  • Provided that you are measuring your current springs with the weight off of them (spring removed or trailer jacked up on one side) then spring # PR722 would be the proper replacement. Each spring has a capacity of 1,250 pounds so 2 of them will have a 2,500 pound capacity and would work with a 2,100 pound axle. We do have shackle bolts. There is a steel shackle bolt, 3 inches long, 9/16 inch diameter, # 166081. We also have steel wet shackle bolt # 126B2 that is the same length and diameter....

  • How to Determine 3 Leaf Trailer Spring Capacity When all Dimensions are the Same for Two Springs
  • Determining the difference between two sets of springs that have different capacities can be difficult at best, especially if the spring has seen use. If you are talking about new springs that have not been exposed to the elements for a period of time, then our springs come in with the part number either painted on the top of the spring (concave side), or stamped into the band that is wrapped around the leafs. In the case of the # PR3 and # PR722 spring ours come in with paint on the...

  • Would Switching to a Leaf Spring with a Lower Weight Capacity Improve Ride of Boat Trailer
  • Swapping out your 3500 lb leaf springs for the 2500 lb springs would improve your ride, IF (and only if) the weight of the boat, trailer, motor, gasoline, cooler, tackle boxes, more coolers, fishing poles and other gear stowed on it will not exceed the 2500 lb capacity of the springs. If the capacity is exceeded, you will actually experience a rougher ride as the trailer will bottom out. What is your axle rated for? If at all possible, you want to match the spring capacity to the capacity...

  • Mounting Center Line and Axle Height Dimensions for Redline Tandem-Axle Trailer Hanger Kit # APT8
  • The axle center line dimension and height from the axles when using the Redline Tandem-Axle Trailer Hanger Kit for Double-Eye Springs, part # APT8, will depend on your axle capacity and which particular springs you are using. My contact at Redneck confirmed this. This hanger kit is intended for use with double eye springs and axles between 2,000 and 7,000 lbs. Your positioning will depend on your choice of springs. The most common spring length for use with this kit is 25-1/4 inches,...

  • For your 2005 Bri-Mar open trailer model CH16-7 with GVWR of 7,000 lbs I would recommend you get 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles, part # PR4B. These leaf springs are designed for use on trailers with 3,500 lb axles like what you should have on your trailer. You should note that leaf springs have a tendency to stretch out over time, so the fact that these leaf springs are a little bit shorter than your current springs at 25-1/4 inches these would be the correct...

  • How to Determine the Correct Replacement Leaf Springs for a 1987 E-Z Load Trailer
  • To be certain of the correct double eye leaf spring for your trailer, I will need to know the capacity of the axle itself. The axle capacity should be listed on a sticker or plate on the trailer frame. Add to that information some specific measurements, and we will be able to get you the correct leaf spring. The measurements we need can be found on the diagram on the product page for Spring # PR722 after the specs. The weight should be off of the spring when you take the measurements....

  • How Can I Determine The Weight Capacity Of the Leaf Springs on a 1996 Mobile Scout RFK-30 5th Wheel
  • To determine the capacity leaf springs you have on your 1996 Mobile Scout RFK-30 fifth-wheel trailer you should look on the frame of your trailer for a plate that will have the VIN number, there should also be a listing for the axle ratings too. You can also tell the weight capacity of the axle by measuring the diameter of the axle. A 3,500-lb. axle will have a diameter of 2-3/8 inches and a 6,000-lb. to 7,200-lb. axle will have a diameter of 3 inches. I am sending a link to an FAQ page...

  • What is the Correct Distance Between the Spring Hangers When Using a PR722 Leaf Spring
  • The distance of 25-3/4 inches would be the correct distance to have between the spring hangers. You have to consider that as the the leaf spring compresses from the weight of the trailer it will flatten out and the overall length of the spring will increase so that the shackle will face the right direction.

  • Measurements of the 3-Leaf Double-Eye Spring for 2,500 Pound Trailer Axles
  • The 3-Leaf Double-Eye Spring, # PR722, does not have a front and back, it can be installed with either eye facing towards the front of the trailer. This is what I would call a symmetrical spring. The center point of the spring is 12-5/8 inches from the center of either eye. I have included a link to our FAQ article on double-eye trailer springs for reference.

  • Can Unique Leaf Springs be Replaced on a Very Old Trailer
  • I believe the hubs are for 2,000 or 2,200 pound agricultural axles which is why the springs look so different. These hubs are designed for very low speed applications (5 to 10 miles per hour according to HADCO) so if you plan on going faster than that you will need to look at replacing the axle and hubs. You could use 2 of spring # PR722. Each spring has a capacity of 1,250 pounds. If a new hanger kit is needed you can use # APS1. When used with spring PR722 the center to center distance...

  • Determining the Leaf Spring Drop From an Empty Trailer to a Fully Loaded Trailer
  • The drop that you will experience with the 3-Leaf Double-Eye Spring for 2,500-lb Axles, # PR722, from a trailer at zero load to full load is going to be 1-1/2 inches. A few things to note with a fully loaded trailer is that you will want at least 3 inches of clearance above your tires and 2 to 2-1/2 inches of clearance from the top of your axle to the bottom of the frame where the leaf spring hangers are welded. You will also want to get the correct hanger kit for the leaf springs...

  • Double-Eye Leaf Spring for a Trailer Rated for 1 Metric Ton (2,200 Pounds)
  • Since a metric ton is approximately 2,200 pounds you will need to go with leaf springs that are rated for at least 1,100 pounds. I recommend spring # PR722 which is rated for 1,250 pounds. With one of these springs on each side of the trailer the capacity will be 2,500 pounds. I have included a link to a video review of this spring for you and a link to our help article on double-eye suspension.

  • How to Determine Hanger Spacing Using 25-1/4 Inch Long Trailer Leaf Springs
  • It all depends on the spring being used, the shackles, and the equalizers among other things. There are some suggested hanger spacing measurements but really you would mock it all up first before permanently welding the hangers in place. For example, if you used suspension kit # APT5 and spring # PR722 that is 25-1/4 inches long then the distance between the front and center hangers and between the center and rear hangers is 29-1/2 inches. That would create an axle spacing of 33-1/2...

  • Can Trailer Leaf Springs Lose Their Weight Capacity Over Time
  • Springs can wear out over time and lose ability to support the same amount of weight they once were capable of. It sounds like you are in need of a new set of springs on your trailer. You will need to determine what weight capacity springs you will need. The same plate that told you what tire size was recommended for the trailer should also have the axle capacity. The amount of springs doesn't necessarily indicate the capacity of the spring. If you need a 2,500 lb axle spring you would...

  • Replacing Inverted Leaf Spring Suspension on Old Utility Trailer
  • The first thing you will want to do is to remove the current springs from the frame and the axle. You can still use your axle if it is in good working order, but you will also want to remove any hardware welded to the axle. To install leaf springs, you will first want a hanger kit. For your single axle trailer, I recommend Redline's Single-Axle Trailer Hanger Kit for Double-Eye Springs # APS1. This hanger kit will have a 1-1/2 inch drop for the front hanger, and a 7/8 inch drop for...

  • How Much Space Should be Between the Top of the Axles and the Bottom of a Boat Trailer
  • Normally when using hanger kit # AP233-H248 with spring # PR722 the distance from the bottom of the frame to the center of the axles is going to be approximately 4-1/2 inches. Subtract half the width of the frame then to the top of the axles that would be 3-5/16 inches. Two inches might work out fine depending on how far the suspension travels but more height would likely be needed considering the heavier load. Hanger kit # APT4 would provide more height since it has taller hangers than...

  • Hanger Spacing Recommendation for 2,500 lb Leaf Springs on a Trailer

  • Replacement Double-Eye Leaf Springs Recommendation
  • The longest double leaf spring we offer is part # PR427, and has 4 leaves. This leaf spring measures 27 inches center of eye to center of eye. This fits an axle with a capacity of 3,000 lbs. You should measure the center of the spring eye-to-eye and choose a leaf spring replacement about an inch shorter. If you are replacing older leaf springs, the eye to eye dimension may be a little longer on the old spring due to sag and wear. For a 3 leaf spring and for a 2,500 lb trailer axle, you...

  • Replacement Leaf Spring Recommendation for a 2008 Interstate Enclosed Trailer
  • Yes, I would strongly recommend you replace all four at the same time. We always recommend they all get replaced at the same time to be safe. Since your trailer capacity is 7,000 lbs and your worn out springs are 26 inches long the correct replacement spring for you would be the Redline Spring part # PR3. Four of these will have 7,000 lbs of capacity and they are 25-1/4 inches long so they will match up perfectly for you. Springs tend to flatten out over time and get longer, so your...

  • Spring Hanger Spacing for Trailer Leaf Spring PR722
  • A lot depends on the hanger kit being used and the number of axles on the trailer. You are correct though the difference between 24-3/4 inches and 25-5/8 inches is all of 1/8 of an inch. Hanger kit # APS1 is for a single axle trailer and using spring # PR722 the hanger spacing should be 25-3/4 inches. But using the same spring and tandem axle kit # APT5 the hanger distance is 29-1/2 inches on center. So you can see it depends on the other suspension components being used. But for...

  • Options for Replacing Double Eye Springs on 60 Year Old Boat Trailer
  • In this case I would choose a new set of double eye springs and then weld new spring hangers accordingly. I have attached a link to our double eye springs for you. For example, you could go with the 3-Leaf Double-Eye Spring, # PR722, which has a 1,250 lb spring capacity (2,500 lb axle capacity). Since your boat trailer is 60 years old it is very unlikely that you are going to find parts that will work without any modifications and if you were to choose to switch to slipper springs, you...
