Double-Eye Spring

Part NumberABCD
SP-05327513"14"26"4-1/4"


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 leaf springs provide the attachment points for your trailer's axle, suspending it from the frame of your trailer. Each spring flexes to absorb road shock as you travel, allowing the axle to move somewhat independently of the rest of your trailer. This helps to reduce wear and tear on the trailer and also ensures a smooth ride.


Double-eye leaf springs attach to hangers that are welded onto your trailer. One end of this spring will attach directly to the hanger with a suspension bolt. The other end will attach to shackle straps that are suspended from a hanger. These straps allow the spring to move and pivot so that it can better compensate for uneven pavement. If you have a tandem- or triple-axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs.


To mount this spring, you will need hangers, shackle straps, and suspension bolts. If you are simply replacing a spring, you may still have hangers welded onto your trailer. You should, however, replace your shackle straps because they are usually the first component to wear out. You may choose to replace old suspension bolts as well. It is recommended that you replace the other leaf spring in your setup at the same time. Because springs can sag and elongate as they wear, this new spring may not exactly match the old one, and the alignment of your trailer could be affected.


If you are fabricating a trailer, you will need to purchase a hanger kit for installation. To determine the type of hanger kit that you need, you must know the specific type of leaf spring that you have, as well as your axle capacity. Depending on the hanger kits used with them, springs can be configured to work for single-, tandem- or triple-axle applications. Hangers and other suspension components can also be purchased separately if there isn't a complete kit that works for your setup.

Video Transcript for Universal Group Trailer Suspension - Leaf Spring Suspension - SP-053275 Review

Today we're going to take a look at the 6 Leaf Double Eye Spring for 6,000 pound trailer axles. This is made of a nice strong, durable, steel construction. It is designed to flex to absorb road shock, provide a nice smooth ride, which will help reduce wear and tear on your trailer. It does ensure a nice level ride on bumpy and uneven surfaces, does mount to your trailer frame with hangers or a hanger kit. We do sell those separately on our website and we do usually list them on this product page as a related product. If you notice on the eyes it does include the nylon bushings already in there.

A few specs on this, the spring capacity of this one spring is 3,000 pounds. Now when this one is matched with one on the other side of the axle, it'll match your axle capacity at 6,000 pounds. I did mention this is 6 leaves, you can see 1, 2, 3, 4, 5, 6. I do want to give you a couple measurements. 2 critical measurements are the spring length and spring width. We're going to measure those just to show you.

Basically the spring length is measured from the center of this eye to the center of this eye. If we take the tape measure and we go straight across you can see 26 inches for the spring length. The spring width, just rotate it, would be here to here. Again if we take the tape measure, it's 1 and 3/4 inch for the spring width. The eye diameters on each end here, they are a 9/16th diameter.

This part number is for a quantity of 1 spring, and one last note I do want to mention. When you go to replace leaf springs to ensure proper axle alignment and suspension performance we do always recommend leaf springs should be replaced in pairs. That should do it for the review on the 6 Leaf Double Eye Spring for 6,000 pound trailer axles.

Jayco, the manufacturer of our 4 year old RV, grossly undersized the axle leaf springs when it was built. The GVWR rating tag on the RV said it was good for 9750# but Jayco only put springs rated for a total of 8000#. Consequently the springs failed after 4 years and less than 5000 miles use. (See picture of old/new springs). I upsized the new springs to a total of 12000# and once again the RV sits as high, maybe 1/2 inch higher than when it was new. Etrailer.com site was easy and helpful to use. The springs and u-bolts arrived in just a few days and were well packaged. Thanks to etrailer we are safely on the road again. 540002

First off I was in need of parts ASAP so I searched the web and found this site, that being said I made a purchase of greasable bolts, spring plates and new upgraded springs, 3 days later I received all Of my parts and installed without any problems. The new springs gave my trailer a much needed lift of about 4-5 inches and improved the ride by 100%. All in all this was a great experience and very good products. I will continue to purchase from them and highly recommend them to everyone who has a trailer! 424813

They work great. I originally purchased the 4000# set but they were flattened out to Mich with a load on it. I now went with the 6000# spring and they their perfect boat trailer axle is no longer extremely close to the boat bottom the ride quality is great it's just to bad all our roads in Louisiana are horrible, but with etrailer and their fast shipping my trailer handles it. 379194

I have a huge old miley horse trailer that has seen better days and all of the leaf springs, bearings, etc needed to be replaced, It wasnt like I could go into a name brand parts store to get them either. So when my husband told me he found everything he needed on etrailer.com, I was relieved. I am very happy with the price and the delivery time. The fact that delivery was free was definitely a bonus because the parts were very heavy. I was a little worried about the condition of the parts when they came, the boxes were pretty beat up (very heavy) but so far I haven't found any problems. 325447

This order was shipped out within 6 hours of my placing the order over the phone. Now that is great service! The 6-leaf spring was an exact replacement for the ones on my 40 foot Big Horn 5th Wheel, except they are better made and seem stronger. I am definitely satisfied with the quality of material I am getting from etrailer.com. 339072

Hoping to remedy the problem I was having with low ground clearance on my 2007 Cyclone Toy Hauler, I decided that a spring change was in order. It has 5200 Lb. axles, and came with springs containing 4 leaves, which had gone a little flat over the years. After comparing information on all of the springs available from etrailer, which was very easy due to their accurate specifications and photographs, I found a set of 6000 Lb. springs (6 leaf) that would fit, and give me a little more height. (This has NO effect on increasing load limit, as the axle is still limiting. etrailer also carries the direct replacement 4 leaf springs it came with.) The springs, along with the also ordered hardware, came in just a few days, and the products were exactly what I had ordered and of high quality. I would definitely recommend and order from etrailer again! Easy! 409176

We are so pleased with our interaction with etrailer. We were dry camping in the desert and had no good access to the website. Lori got us the right parts we needed and even gave me her direct line number in case we needed it The only bad thing was one of the boxes was damaged and some of the nuts we needed were missing but we were able to use the old ones. We had to replace leaf springs. This is not etrailer's fault though. We would use them again in a second. Very friendly and helpful. Thanks for getting us back on the road. 595996

I purchased a tractor, and it came with a home made equipment trailer with two 7,000 lb axles. It is an incredibly strong trailer, but they used light weight single leaf springs! Not safe! Since I didn’t want to cut and re-weld the hangers, these springs worked perfect with the dimensions I have. They give me a capacity 2,000 lbs under the axle rating (12K vs 14K). I also ordered u-bolts, return springs, adjusters, etc. All parts shipped quick, came on time, and were packaged well. I’ve ordered from etrailer before, and I’ll order from them again! 481900

Comments

Outstanding. I am very satisfied with the shackles, and new springs. The shackles are especially good because they are very beefy and have the grease fittings for easy lubrication. We can feel a positive difference in the way our 5th wheel rides and handles, which I really didn’t think we would. I show off the shackles to members of our RV club and several say they are going to get them too.

These springs are just what the doctor ordered for my overweight enclosed trailer! My previous springs were so stressed, the trailer would "bottom-out" with every bump in the road.

I'll continue to order items from etrailer.com and I recommend you do the same! 418346

Do you have a question about this Trailer Leaf Spring Suspension?


  • Replacement 26 Inch Leaf Springs, Shackle Straps, And U-Bolts
  • To give you the correct leaf springs, I would need to know the capacity of your axle or what your Gross Vehicle Weight Rating (GVWR) is not just the weight of the trailer itself. This is the loaded capacity of the trailer. We have a few options for 26 inch leaf springs: 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 26" Long # SP-051275 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 26" Long # SP-124275 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles - 26" Long...

  • If you use the 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long # SP-111275 which have the same capacity, I recommend the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs - 3-1/4" Front/Rear/Center # APT5 for a tandem axle application. When you follow the attached photo, this will give you the 33-1/2 inch axle spread. For your 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # SP-053275, you can use the same system but replace the equalizers with...

  • 6k Trailer Leaf Spring and Hanger Kit Availability for Tandem Axle Trailer
  • We have a few 6k leaf springs that could work for you but we need to know the length of the springs that you need. For a 25-1/4 inch spring we have the part # SP-111275. For a 26 inch long spring we have the part # SP-053275, and for a 25-1/8 inch spring we have part # SP-221275. For a tandem axle hanger kit we then have the part # AP233.

  • How To Properly Measure For Replacement Leaf Springs on a Trailer with Triple Axles
  • First thing you will want to do is pick leaf springs that are as close to the axle capacity as possible. It is also highly recommended to replace your leaf springs in pairs, new set per axle. Thanks for your pictures it looks like you actually have a triple axle trailer with 6 leaf springs that have 6 leafs per spring like the # SP-053275. You will want to also measure the distance from eye to eye of your old leaf springs and then pick a leaf spring with the same weight capacity of...

On the EZ Flex the distance from the center of the mounting hole to the center line between the 2 bottom holes, straight up and down, is 2-7/8 inches. If your 4-3/4 inch measurement is diagonal then you will be good to go with this kit. For a u-bolt kit you can use # APUBR-9. The shocks might actually feel more effective with the EZ Flex kit...

  • How to Determine the Correct Replacement Double-Eye Trailer Leaf Spring for a Boat Trailer
  • A trailer leaf spring will wear out over time and the wear will likely lengthen the spring. Therefore, the correct replacement leaf spring will likely be shorter than the leaf spring you have on your trailer now depending on the amount of wear that has occured. If the leaf springs you have on your trailer now are 26-1/2" long from the center of each eyelet, I recommend using a 26" long leaf spring like part # SP-124275 for 2,000 lb, part # SP-051275 for 4,000 lbs, part # SP-256275...

  • Recommendation for Adding Third Axle To Trailer Suspension
  • The Dexter Heavy Duty Suspension Kit # K71-360-00 is designed for 33 inch axle spacing. To add your third axle, you cannot simply add a hanger spring and axle. You can keep your 35 inch spacing but you will need to relocate your hangers. I've attached an article to help with the proper positioning of your axles. You will need to add another equalizer of the same dimension as you have to each side and then add the same leaf springs and shackle straps as what you currently have....

Which means you most likely have 6k axles. We have a few options for that capacity for leaf springs but you'll need to measure the length of your current springs to be sure. If you have 25-1/4 inch long springs you'd need part # SP111275. If you have 26 inch long springs you'd need part # SP-053275. If...

The amount of leafs do not matter as much as long as the spring is rated for your axle capacity. I recommend TruRyde Shackle Link part # TRSL225. The shackle straps are 2-1/4" long.

  • How To Determine Trailer Leaf Spring Replacement Based on Axle Capacity and Other Components Used
  • For your replacement leaf spring, there are a few things to consider. The number of springs in the stack doesn't determine the capacity, so you will need to know the capacity of your axle so you don't have springs that are too stiff or not strong enough for your application. For instance, if your springs are for a 3,500 lb axle, then the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # SP-210275 may be the correct replacement even though it is 4 leaf versus 6 because the...

  • Could Replacing Older Trailer Leaf Springs Gain Additional Height to Trailer
  • Most likely your springs are sagging a bit if they are over 10 years old. Since it's a good idea to replace those anyway that's probably a good place to start. In the 7,000 lb capacity we only have one size of 24-7/8 inches as part number # SP-198275. Even going with a new set of 6k springs will be an upgrade. For that we have a few lengths like part # SP-111275 which is 25-1/4 inches long, # SP-053275 which is 26 inches long, or part # SP-221275 which is 25-1/8 inches long.

  • Distance Between Hangers with 26 Inch Leaf Springs
  • We don't carry the MR4 leaf springs but based on my research they look like they are 26 inch double-eye springs like part # SP-053275. For springs of this length and the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs # APT4 the hangers are going to be spaced 30-1/4 inches apart. I have added a link to a video review of the hanger kit as well as a couple help articles on trailer suspension which I recommend checking out.

  • Could Universal Group Leaf Spring SP-053275 Fit a Heartland Cyclone
  • When picking out leaf springs for a trailer priority one is the proper capacity. If you have 6k axles on your Heartland Cyclone then the 6-Leaf Double-Eye Spring # SP-053275 would fit and work well as a replacement. The hanger kit part # K71-360-00 would then work well with this spring as well. If your older springs were worn out and sagging because of that these would eliminate the sag. Since these springs are a little bit thicker the trailer would sit up a bit taller if the springs...

  • Recommended Leaf Springs and Metal Bushings for 2004 KZ Sportsman 5th Wheel Trailer
  • The 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # SP-053275 are compatible with any trailers that have that eye to eye measurement and have a 6,000 lb axle. Each spring will have a 3,000 lb capacity. You absolutely can trade out the bushings for the metal bushings. I recommend the Bronze Bushings - Qty. 4 # K71-291-00 or the Never Fail Bushings - 9/16" Inner Diameter, 11/16" Outer Diameter - 1-3/4" - Qty 14 # LC279685.

  • Tandem Axle Trailer Spring Hanger Kit and 6K Leaf Springs
  • The hanger kit I recommend is part # APT3HD which includes front, center and rear hangers, equalizers and bolts. This kit is good for axles up to a 7K rating and most 3-inch diameter axles are rated for 6000 to 7200-lbs. The linked video will let you see the kit contents. Please note the kit does not include parts to mount the axle to the suspension; for that use # APUBR-8, one kit per axle. For double-eye leaf springs please refer to the linked page that displays all 6K rated springs...

  • Bronze Bushings for Double-Eye Leaf Spring
  • There are bronze bushings you can use to replace the bushings on the 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles # SP-053275; they would need to be added separately. What you can use is the Bronze Bushing # D014-077-00 which is a quantity of one or the Bronze Bushings # K71-291-00 if you wanted a quantity of four. These bushings have a 9/16" inner diameter, 11/16" outer diameter and measure 1-3/4" long. I've added links to reviews of both the bushings and leaf spring for you...

  • Which Direction Should Leaf Springs Be Installed on a Trailer
  • The steel band around leaf springs, such as # SP-053275, is typically installed in front of the axle. However, it doesn't really matter either way.

  • Boat Trailer Bottoms Out Using Leaf Springs for 6,000 Pound Axles
  • It sounds like your current suspension set up is underrated for the application. But not to worry because we can get you set up. The springs for 7K axles, # SP-198275, are going to be stronger so they will not sag as much and retain the ride height better. But the trade off is that the ride quality will be stiffer. The springs for 6K axles and that have 6 leaves, # SP-053275, may put you in the same boat as you are now. The weight of the trailer is going to compress the springs, flatten...
