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.

I pull a toy-hauler 5th wheel trailer between Alaska and the lower 48 through Canada twice a year. Much of the road is rough and caused me to break a leaf spring every trip. Since installing a shock absorber system and upgrading from 5-leaf to 6-leaf springs, I have so far eliminated suspension damages on the route.


Comments
Im still very pleased with this suspension system. I will add it to any trailer I acquire.
Brian - 10/19/2022

Excellent service and selection. Parts arrived one day EARLY and worked perfectly.




by:

The leaf springs fit my trailer perfectly now I feel like I have the right load capacity for my trailer
Thanks




by:

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.




by:

After talking with etrailer rep. I was sent the wrong size. I sent them back and bought new one's locally.




by:

I had rusted old bolts and leaf springs, these were great replacements. No issues look great work well and fast shipping.
added 3 inches of lift upgrading the springs.




by:

Good quality and good fit. They went right together and after a year have not required any retorque. No rust either.




by:

It went together fine, lifted the trailer bed a good 5-6 inches off the tires and looks strong; time will tell. First picture is BEFORE, 2nd pic is AFTER




by:

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!




by:

Excellent service, they responded to my queries on the same day , delivery on time ..what else can you ask for?




by:

My wife ordered me something for my birthday off [online] (small whatever). I ordered these springs a week later and they still got here first. Very fast shipping.




by:

The service from etrailer is top notch. Great service and employees. I would recommend them for any trailer parts needed.




by:

Etrailer made my purchasing and acquiring the parts I needed very easy. Customer service was exceptional!

These leaf springs were about the half the price as all the ones that I saw, and they shipped in two days! Got them installed and they look great !




by:

I had great costumer service. When one of the springs I ordered was lost, Noah stepped up and expedited a replacement. Very professional all the way.




by: 08/22/2021

EXCELLENT QUALITY AND FIT - I JUST HAULED MY 25 FT CRUISERS-(FIRST TIME AFTER INSTALLATION OF NEW LEAF SPRINGS ) THEY HELD THE WEIGHT VERY WELL !!!!




by:

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.


Comments
Its been a year now and Ive logged over 5K miles on the replacement springs and they are holding up well. Trailer is straight and true and I havent noticed any compression. Great product!

All arrived on the date committed and was complete.

Brandy was super helpful. My package came in two days! I didn’t realize Etrailer was a one stop shop. Will definitely be buying from you guys again, thanks!




by:

I wanted to put larger tires on my 5th wheel trailer. It had 225/75/15 load range D from the factory. I tried first by ordering HWT- Series S5 16x61/2-6 part # AM 22658 HWT B wheels, and 4 Sailun S637 -ST 235/80/80R /16 load range 129 tires. Found I didn’t have enough room for them to fit. So I ordered 4 new springs Item SP - 053275 six leaf springs and a larger equalizer item TREQ-310. All the parts except the tires we’re purchased from etrailer.com. My trailer already had the axles flipped and the longest hangers installed. So getting the new springs and equalizers did the job I now have the space to use tires that will allow me to actually put a near full fresh water tank for dry camping. I am very careful about what I put in my trailer and weigh it frequently and use a safety factor in loading! etrailer was very helpful in suggesting items, and were fast in shipping . I would use them again!




by:

I had these springs on order for almost 7 months from another vendor with no delivery date in sight. So i searched and found them on etrailer website for less money and they were in stock and delivered to me within a weeks time.

Awesome pricing and service. Will definitely order from them again.




by:

Never had any problem with parts I’ve purchased from Etrailer.

See what our Experts say about this Universal Group Trailer Leaf Spring Suspension

  • Leaf Spring Recommendation for Trailer with 3 inch Diameter Axles with Springs are 26 inches Long
    A 3 inch diameter trailer axle is very commonly a 6k axle so you are on the right track with your estimate on the capacity. We have the part # SP-053275 which is a 6k leaf spring that has 6 leafs like you need and is 26 inch from eye to eye.

  • Distance Between Front and Rear Suspension Hanger on Single Axle Trailers
    For single axle trailers you want the front and rear hangers to be the exact length of the leaf spring measured from eye center to eye center. So for the leaf spring part # SP-053275 you would need the hangers to be 26 inches apart.

  • 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.

  • What Distance Should There Be Between Axles On A Triple Axle Trailer?
    From what I can find, for 5200 lb axles you will want 29.5 inches between the hangers center to center and 33.25 inches axle center to center for double eye springs in most cases. Your equalizers and shackle straps will take up some of that measurement difference between your springs.

  • How to Determine Correct Double-Eye Leaf Spring Replacement for 6,000 lb Axle
    I can tell you how to determine the correct leaf spring replacement, though those numbers don't have anything to do with size. They are probably a serial number or some other type of manufacturer ID but nothing of consequence. Instead, the best way to determine if a double-eye spring will fit is by measuring the length from the center of the spring eye to the end of the spring, as you can see in the accompanying diagram (the best way to get an accurate length of a leaf spring is with the...

  • Replacement Leaf Spring Recommendation for 2009 Forest River Cardinal
    Typically as springs wear out they stretch or get longer as they flatten. So when picking out a replacement spring normally you go with one slightly shorter than what you measure but most importantly the correct capacity based on the axle. The temptation is to go with a higher rated spring than needed but this will just give you a harsher ride than ideal as the spring will move less. So the best solution is the leaf spring part # SP-053275 which is a 6k spring that is 26 inches long. This...

  • Availability of Leaf Spring # SP-053275 with Taller Height?
    The D dimension of the # SP-053275 is close enough to the 4-1/2 inch figure it would not be an issue. We don't have anything that matches everything else with just that dimension different.

  • Determining Rough Weight Capacity Of Trailer
    Based solely on the information you gave, I would guess that you have a capacity between 2000 lbs max and 3500 lbs max. It is not possible for me to determine the exact weight capacity based on dimension. You will need to determine your axle capacity and the capacity of each individual component. The lowest rated component becomes your maximum capacity for your trailer. Based on your tires, you will be limited to 3200 lbs already. Most of the axles that are 38mm or 1-1/2 inches are...

  • Determining Correct Replacement Leaf Springs For 2007 Keystone Montana5th Wheel W/ 6000lb Axles
    I would be happy to recommend replacement leaf springs for your 2007 Keystone Montana 3075RL 5th Wheel Trailer but I will need to know the center eye of spring eye to center of spring eye measurement, and the width of the leaf spring first. You will need to take this measurement with no weight on the axle or you will get an inaccurate measurement. For example the 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # SP-053275 is rated for 6000lbs measures 26" from center of...

  • Recommended Leaf Springs For Triple Axle Boat Trailer W/ 5200lb axles
    You are correct that the leaf springs on your triple axle boat trailer have more than likely flattened out and have gotten longer since they are 18 years old. For a replacement I recommend the 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # SP-053275 which measure 26" center of spring eye to center of spring eye and will work perfectly as a replacement. A 25-1/4" spring may work, but it is unlikely that your current springs stretched 2" over time. I included a video of...

  • Leaf Spring Replacement for # SP-053275
    If you got 15 years of regular use out of the # SP-053275 I'd say you did good in that regard as trailer suspension doesn't typically last forever. It's highly recommended to replace leaf springs on trailer in pairs for the left and right side of the trailer but if you can only do one spring right now and you will be using the trailer it is safer to fix the one spring instead of using the trailer with a broken one. These springs are a solid option and I don't think going to a slipper...

  • How To Choose Correct Replacement Leaf Springs for Jayco Designer 5th Wheel
    In order to choose the correct replacement leaf springs for a trailer you'll need to know the axle capacity and unloaded length, the number of leaves is not really pertinent. The 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles part # SP-053275 for example measures 26" long eye to eye unloaded and is designed for 6,000 lbs axles. The axle capacity can be found on the axle tag in the center of the beam.

  • How To Tell If a Trailer Leaf Spring Needs Replaced
    In regards to trailer leaf springs, as they wear out of over time they will start to flatten and lose their rigidity and flex. There isn't really an exact degree of wear that will be had before the springs needs replaced, it's mostly done by visually inspecting the springs and their curvature. It looks like from the attached photos that the springs are mostly flat therefore I recommend replacement. In order to find the correct replacement you'll need to unload the springs and record their...

  • Leaf Spring that Fits 2011 Keystone 300MP Toy Hauler
    The leaf spring part # SP-053275 that you referenced is correct for a 6,000 lb axle like you have so it would work well in that regard. You would want to make sure the length of this will work too as it is 25-1/8 inches. Looks like your Lippert leaf spring is about 26 inches long so this would work great.

  • Why Are There 26" Long But Not 26.5" Long Trailer Leaf Springs
    Correct, as leaf springs wear out over time they will stretch so the new replacement you need is likely going to be shorter. That said, you're also supposed to measure the spring unloaded so this will also factor into the length. I am not sure what capacity you need but you should choose one that matches the axle capacity as close as possible. The 6-Leaf Double-Eye Spring part # SP-053275 for example is rated for 6,000 lb axles. I have attached our entire 26" leaf spring selection below...

  • What is the purpose of a leaf spring rebound clip and where does it go?
    The clip you are referring to on the 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # SP-053275, and other leaf springs, is called a Rebound Clip. This is meant to keep the leaf springs from breaking on hard impact. It is typically mounted about a 1/2" from the end of the shortest leaf. The leaf spring is typically mounted in a way that the clip/band is forward of the axle, however, it does not make a big difference either way so I wouldn't worry about that too much.

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.

    Typically when you replace the leaf springs it is best to match what is already on your trailer.

Since this is a secondhand trailer, it is possible the previous owner should have installed 26" leaf springs and did not but that is impossible to determine.

  • Should All Trailer Leaf Springs be Replaced at the Same Time
    When you are replacing a leaf spring you definitely want to replace all of the leaf springs on your trailer. The reason for that is leaf springs wear down over time and by replacing them at the same time ensures you will have even support on both sides of your trailer without any sag or lean. In regards to the correct replacements, that is going to depend on whether or not you have double-eye springs or slipper springs, your trailer's axle rating and most importantly, a number of measurements.

    There is no centering pin that comes with the 1-Leaf Double-Eye Spring for 6,000-lb Trailer Axles # SP-115275 but there is a "nib" that helps keep it centered in the spring seat. I'm not quite sure what you are referencing unless it is the bolt in the middle of a stack of leaf springs like part # SP-053275 which helps keep the leaf springs aligned. If you have something different please send me a picture of it so I can see if it is something that we carry.
