Part NumberABC
PR525-1/4"3"12-5/8"

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 PR5 Review

Today we are going be taking a look at part number PR5, the 5-Leaf Double-Eye Spring for 5,800-lb Axles. Before 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 spring here at the leaf bolt. This spring has a 12 5/8 inches half-length. One more measurement you will need to know is the spring height. To get the spring height well actually draw an imaginary line from the center of the eye to the center of the eye.

And using that line we will measure from it to the spring surface. This spring is 3 inches high. You will notice that it does have two 9/16-inch holes for mounting. They do have nylon bushings in them. The nylon bushing helps to prevent metal on metal contact while the spring is on the trailer. It does have 5 leaves within it giving it a capacity of 2,900 lbs. When you multiply that by two per axle, you get your 5,800-lb total axle capacity. And that does it for part number PR5, the 5-Leaf Double-Eyed Spring for 5,800-lb axles.

I just wanted to let you know what a GREAT experience it has been ordering from your company. I have never had a company check up or keep me as informed on what was happening with my order. It is a great relief to know that there are still some companies that care and are not just interested in "a sale." I have attached some pictures of the old springs I took off and the new one's. The old ones were stretched flat with my dump trailer empty. When I put the new ones on it even raised the trailer up at least 4 inches. 29072

Product was great. arrived early. But it was the wrong size, greatly in part, my fault. I measured the lenght of the leafs instead of the lenght from eye to eye center. Wish during the ordering processes it was explained on how to measure. I have looked at wheels and wheel bolt patern and the instructions for ordering the correct bolt patern there are great. I am sure its probably common knowledge with those that deal with leafs on a regular basis but for those of us that will order this only maybe once in a life time, measuring instructions would have been greatly appreciated. Loved how customer service was always in contact and still is after delivery. 26134

I ordered new springs (PR5), hanger kit (APT5), and u-bolt kit (APUBR-1) for the worn out suspension on my 16 year old flatbed car trailer that has mainly been misused as a hay trailer. Whenever I receive boxes containing pieces/parts I immediately inventory to make sure everything is there. It was. It all went together as it should and I've just taken it for a test drive over some rough roads. It tows like a new one even though it sure doesn't look like it. I recommend all of these products purchased as a group because of (seemingly) good quality, proper fit, and popular prices. 191982

I recently bought Dexter E-Z Flex equalizers and was told by multiple forum members, "Since you're unbolting your leaf springs anyways it's cheap insurance to replace your 4 leaf springs with 5 leaf springs" After much online research I found etrailer had the best price when you took advantage of their free shipping special. I could not be happier with their service and FAST shipping!!! 142844

I just finished installing the leaf springs on my triple axel boat trailer and I'm very satisfied with the result. Shipping was quicker than anticipated… One suggestion is having a complete hardware kit that is galvanized for salt water boat trailers. i.e Shackles, equalizer, and bolts with nylon lock nuts. Thanks again for a Great Product! 38691

The springs are great! Not only did they go on smoothly, but they got here promptly too! I was very much impressed by the customer care throughout my purchase. I actually received three emails the day I ordered, each from a different person in the chain and updating me on the progress towards shipment. Thanks for the prompt, courteous service. 19569

As described, but a heavy part like a leaf spring should be better packaged for shipping. The springs banged together all the way to California arriving with many paint chips and scratches. I doubt any of this would affect the performance but if you want a fresh new appearance they will need to be repainted when you get them. 182993

The leaf springs and U bolts were of good quality (what can you say about leaf springs). The only problem was insufficient capture and cushioning in the shipping container. I realize 4 springs are heavy but these busted completely through the box and luckily UPS kept the springs and box together. 133548

Received my order right on schedule. The box was much larger than the items but packaged ok. I think a smaller box would work better as all the weight was in the bottom of the box. I haven't installed them yet so I can't review the product itself but appears it will work as designed. 139928

  • Hanger Spacing Dimensions for Installing Double-Eye Leaf Springs on a Trailer
  • The Trailer Leaf Spring, 2250 lbs. 6 Leaf, item # PR626, is sold as a replacement spring for older trailers and measures 26 inches for eye to eye, center to center. If you are replacing the springs and hangers you will need to use the same center to center dimension as the original mounting brackets. These springs are designed for a 4,500 pound axle. If you are building a new trailer you will need to determine the weight capacity of the axle you will be using and order springs and hangers...

  • Trailer Suspension Parts Needed to Increase Trailer Capacity from 7000 to 10000 lbs Gross Weight
  • Your best bet for upgrading the suspension on your trailer with 5,000 lb axles is to change out the springs from 1,750 lb capacity each to at least 2500 lb capacity each. Helper springs would not increase the capacity of your original suspension, they are designed to help your suspension handle loads up to the rated capacity of the suspension. If your trailer suspension is built with double eye springs you will need to measure the springs with no load on them from the spring eye center...

  • Recommended Hanger Spacing For 4-Leaf Springs # PR4 on Tandem Axle Trailer
  • You mention that you have a tandem axle with 3 inch axles. A 3 inch axle has a weight capacity rating of 6,000 lbs to 7,200 lbs. The leaf springs for that axle would be the part # PR5. These springs have a weight capacity of 2,900 lbs and are designed for 5,800-lb and 6,000-lb axles. The PR4 springs you have mentioned show a weight capacity of 2,400 lbs. So two of the # PR4 springs are designed for 4,800-lb to 5,000-lb axles. I would recommend to check the weight capacity of your axles...

  • Replacing Fifth Wheel Springs with Higher Capacity
  • Your springs should be measured eye-to-eye with no load on them to get the most accurate measurement. Your springs are sitting flat either because they are worn or because they are over loaded. You may go up to the 6600 lb springs as long as the eye-to-eye length and the width will fit, but the higher capacity springs WILL NOT increase the weight capacity of your trailer. The weight capacity will still be limited to whatever the lowest rated component of the system is, whether it...

  • Electric Brake Assembly Recommendations for a Tandem Axle Trailer with 5,200 Pound Axles
  • A 5,200 pound axle is most like a de-rated 6,000 pound axle so 12 x 2 inch brake assemblies are most likely correct. Measure the pad width and the inner diameter of the hub where the pads touch to determine if 12 x 2 is the correct size. I have also included a picture that shows the bolt hole measurements for the brakes you have referenced. If all of the measurements are the same as what you have then I would go with the Nev-R-Adjust brakes like # 23-458 and # 23-459. After the initial...

  • Can a 3,200 Pound Capacity Trailer Change to a 5,000 Pound Capacity by Changing Axle and Springs
  • Adding a higher capacity set of springs does not change the capacity of the trailer. The axle capacity will remain at 3,200 pounds. Like you said, you would have to replace the axle and springs for a higher capacity. This will also necessitate different wheels and tires that are rated higher as well because the new axle will have different hubs and you will need wheels to match and tires for the higher capacity. Some of the suspension components will probably need to be replaced as...

  • Trailer Spring Kit # 2-1020 Recommendation for an Old Boat Trailer Converted to a ATV Trailer
  • It sounds like you may have a vehicle leaf spring on your old boat trailer as we do not carry any leaf springs that are that length. The longest one we have is 27 inches long and is designed for 3,000 lb axles. That spring is the Redline Leaf Spring # PR427. The leaf spring that would closely match the axle capacity of your trailer would be the Redline Trailer Suspension # 1020. For a kit I would recommend a 3-Leaf, Double-Eye Spring Kit for 2,000-lb Trailer Axles # 2-1020. You...

The 5-Leaf Double-Eye Spring, part # PR5, is the right spring to use with the Single-Axle Trailer Hanger Kit for Double-Eye Springs, part # APS4, that you have. The reason the shackle angles toward the the axle is because the spring length is 25-1/4 inches long and the correct distance between the hangers is 25-3/4 inches. Since the spring...

  • Can a Trailer with 5,200 Pound Axles Use 5,800 Pound Double-Eye Leaf Springs
  • The failure of the leaf springs may be a result of another component in the system that has a problem and needs to be replaced. I recommend having a shop take a look at the suspension components to make sure everything is working correctly and nothing else needs to be replaced. Adding higher capacity springs will give you a stiffer ride, but if the trailer manufacturer determines it permissible considering the problems you have had in the past, you should be able to use the larger springs....

  • Which Bronze Bushing Fits in Double-Eye Trailer Leaf Spring # PR5

  • Can Springs Be Upgraded on 5th Wheel Trailer With 5,200-Lb Axles

The weight capacity will still be limited to whatever the lowest rated component of the system is, whether it be the axle, the shackles or the equalizer. If you decide to go with the higher-rated springs, you will be making the axle and the spindles the lowest-rated component, which can cause failure...

  • Replacement Double Eye Springs and Suspension Kit for a Triple Axle Trailer
  • All of the hanger kits we have for double eye springs are going to be for 1-3/4 inch wide springs because that is what the majority of double eyes are presently. What you can do is replace the springs which would allow you to use the right hanger kit and provide you with all new suspension parts which is the ideal way to go. We carry one 26 inch long spring measured from the center of one eye to the center of the other eye. It is # PR626. Each spring has a capacity of 2,250 pounds. However,...

  • How Tight Should U-Bolt # 176500 Be on Trailer Suspension
  • When our installers install u-bolts as part of a suspension project, they torque them down to about 70 foot pounds per nut. When the u-bolt plate starts to flex a little, then you know they are tight enough. I have included a link to a video that should help.

  • 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,...

  • Parts Needed to Increase the Capacity of a Boat Trailer
  • The only way to increase the capacity of a trailer is to get a higher capacity axle (and related suspension components, hubs, tires, and wheels). I would go with a 3500 pound axle since that is what the springs, when combined, are rated for and because it will cover the weight of the boat with ease. You may need to also beef up the trailer frame as well. The trailer manufacturer may be able to tell you if the frame is rated high enough as-is. For wheels and tires, I recommend an ST205/75-14...

My contact at Redneck suggested that if you are fabricating a tandem-axle trailer from the various separate components you purchased you may be better off using the 5-leaf spring # PR5 along with the corresponding hanger kit, # APT5, which will work for 3-inch axles rated between 5,200-lb and 7,000-lbs.

  • Leaf Spring Recommendation for 5k Axle that is 25-1/4 inches in Length
  • Since you need at least a 5k rated spring that is 25-1/4 inches in length (like the # PR4) you would actually want the part # PR5 which is a 6k rated spring. A little more capacity than needed is better than a little less so this would be your best option. We don't currently have any 5k rated 3 inch axles so you would need to contact a local trailer shop in your area who can custom order you in an axle to the specs you need.

  • Suspension Recommendations For Building Tandem Horse Trailer
  • Building a trailer is a big task. You will need to first find the correct axles for your trailer that have sufficient weight ratings for your trailer. I have attached a helpful article that explains what suspension is needed for a tandem trailer you can check out. There are a lot of things to consider when selecting a hanger kit. First you should select a kit that will accommodate the wheel and tire combination you are planning on using. The part # APT5 kit would be a good choice for...

  • Torque Spec for Trailer Suspension Shackle Bolts
  • We recommend that shackle bolts be tightened fully, then backed off slightly to allow free movement. You can certainly use a medium-grip thread sealer like Loctite Blue, if you wish, but the above still applies. The shackle/equalizer bolts can be re-used if absolutely necessary but you'll want to be careful to check them for signs of wear and to confirm the threads are okay. All things considered, if you are going through the effort to dismantle your suspension (to replace your springs,...

  • When Replacing Trailer Leaf Springs Go by the Weight Capacity of the Axle
  • Yes, when replacing trailer springs, you will want to go by the listed axle capacity of the springs. It would be best to replace both springs at the same time. I also recommend that you check other suspension components before installing new springs. The suspension is only as strong as its weakest link. Even though the # PR5 spring is rated at 6,000 pound axles, 3,000 per spring, you will still need to stay within the capacity of your axle at 5,000 pounds and not overload the trailer....

  • Distance Between Hangers On Trailer With 6000 LB Axles
  • The distance between the center of the middle hanger and the center of both the front hanger and the rear hanger is 29-1/2 inches. I have attached a drawing that shows how they should be located. On the drawing the dimensions are as follows: A is 29-1/2 inches, B is 29-1/2 inches, C is 33-1/2 inches, and D is 4-1/2 inches. This will give you the proper placement of the hangers for your trailer with the 6000 lb axles. I have also included a link to a helpful article that explains double-eye...

  • Replacement Leaf Springs for an Older Trailer with 5,200 Pound Axle
  • You are going to want to measure the eye center to eye center on your existing springs to determine replacements. You have to take the measurement with no weight on the spring so you can jack up one side of the trailer and measure that sides spring. Over time, a spring can flatten out a little and the measurement could be slightly different than what a new spring will measure. You are most likely going to find that spring # PR5 or # TE30 is a fit. PR5 is more common but both are popular...

  • Should the Space Between Tandem Axle Trailer Tires Be the Same On Both Sides of the Trailer
  • Is there more weight on one side of the trailer? If so, you would want to make sure the load is distributed evenly from side to side. Are you on level ground when you measured the distance between the tires? If not, that would cause one side of the suspension to have more of a load on it. I would measure the distance between the spring hangers on both sides just to make sure the problem is the springs and not where they are attached on your trailer. If everything checks out it might...

  • Replacement Leaf Springs for a 2007 Enduramax Toy Hauler Trailer with 6K Axles
  • To determine the proper replacement springs for a given trailer you would need to measure the eye to eye distance on the existing springs with no weight on them. You can do this by removing the spring or by jacking up one side of the trailer and then measuring it. However given that the springs on your trailer have flattened out, the measurement is not going to be exact. Spring # PR5 is not going to have a high enough capacity for a 6k axle. Spring # PR6 is more likely correct at 3,300...

  • How Thick is Trailer Leaf Spring TE30 at the Center and Does it have a Locating Pin
  • First, spring # TE30 has a specific application. It is meant as a replacement for 6k mobile home axles. If you are fabricating a trailer you would be better off with 5-leaf spring # PR5 which will work for 3-inch axles rated between 5,200-lb and 7,000-lbs. But as far as thickness at the center of the spring, the leaf itself is approximately 7/8 inches thick. Counting the nub, locating pin at the bottom (there is no pin on top) that fits in the spring seat it is 1.18 inches thick overall...

  • Spring Hanger Dimension Recommendations for Installing a PR5 Leaf Spring
  • If your current springs are like the # PR5 which is 25-1/4 inches from eye to eye the correct measurement to use for the hanger spacing is 24-7/8 inches. At one point 25-3/4 inches was recommended, but we found that 24-7/8 inches was a much better dimension to use as it made the shackle strap face the correct direction. The # 30-20 should work well as a rear hanger. Going with longer shackles would move the axle closer to the trailer frame so that may not be an ideal solution for you....
