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.

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

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 etrailer.com, 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

Thanks to etrailer.com, 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

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

I've just opened the box... they look as advertised and as long as they hold the load stated I'll be happy.... my intention is to never have them past about 1800-2000 lbs so all should be good.... 23037

  • 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 on tr

  • 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.

  • Trailer Leaf springs # PR4B Recommendation for a 2005 Bri-Mar Open Car Trailer CH16-7
  • 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 length.

  • 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. You ca

  • 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 of the

  • 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 you choo

  • What is the Correct Distance Between the Spring Hangers When Using a PR722 Leaf Spring
  • The distance of 25-5/8 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.

  • 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.

  • 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. If you ca
