Part NumberABCD

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 had an alignment issue with my fifth wheel camper. Figured out that one side had flat springs. These springs worked perfect and fixed my alignment issue.


Very informative of the questions I had before placing my order. Good shipping time.


Great price, fast shipping.


Want to make sure both sides are the sa me.

  • How to Determine Correct Replacement Leaf Spring for 2004 Forest River Toy Hauler Trailer
    Trailer leaf springs will measure differently when under load so its tough to get an accurate eye-to-eye dimension without removing the spring. Also, after years of use a leaf spring can stretch and actually lengthen by as much as 1/2 to 3/4-inch. Since you are seeing some sag and the trailer is a decade old that is likely to be the case unless there is another suspension component that is damaged. I checked the Forest River website for any information on your toy hauler's suspension parts...

  • What is the Eye Diameter of Double-Eye Trailer Leaf Spring e64SR
    The 9/16 inch measurement would be including the bushings already installed in spring # e64SR. The bushings can be removed but how easy they are to remove varies from spring to spring. But the bottom line is that you could get them out if you wanted or needed to. The diameter without the bushings is 11/16.

  • Recommended Double-Eye Leaf Springs For 2007 Fifth Wheel Travel Trailer
    In order to make sure you get the correct replacement parts you will want to take a measurement or two. It would be best to measure the spring while the trailer is lifted and weight is taken off the spring. You need the eye-to-eye measurement to make sure you get the right length spring for your trailer. It is recommended that new leaf springs should be installed on both sides of the trailer to make sure the suspension is equal and performs well. The leaf double-eye leaf springs we...

  • How to Pick Out the Correct Capacity Leaf Springs for a Trailer
    What is more important then the amount of leaves that are on the spring is the weight capacity of the spring. The easiest way for you to determine which leaf spring has the correct capacity for your trailer would be for you to check the weight capacity of the trailer and then get leaf springs that have that capacity. The easiest way to determine the capacity of your trailer is to look for the plate near the coupler of your trailer that should have the axle capacities and overall capacity...

  • Hanger Spacing Recommendations for a Triple Axle Trailer with 25-1/4 inch Springs
    I did some checking and it looks like on springs that are 25-1/4 inches in length measured from eye to eye you will want the distance from the first hanger to the second to be 29-1/2 inches, from the second hanger to the third you will need it to measure 34 inches and from the third to the fourth 29-1/2 inches. This measurement is from center to center of the hangers. Check out the pictures I attached that show

  • How Much Clearance is Needed Between Trailer Axle and Trailer Frame
    Since your axle is mounted on top of the leaf spring you will want between 2 and 2-1/2 inches between the top of the axle and the trailer frame. You will also want 3 inches of clearance between the top of the tire and the fender. Check out the FAQ article on trailer suspension I attached also.

    What you have is a little long however still may work. It's hard to give you exact numbers sice we don't currently carry any 27-1/4 inch springs. However, I can tell you the measurments that we recommend for 27-1/2 inch springs are 32 inches from front hanger to second, 36-1/2 inches from second to third, and 32 inches from third to fourth. All measurments are center on center. Your numbers are fairly close but if they are too long it will decrease the amount of travel in the trailer's...

  • Where to Measure a Trailer Axle to Select a Replacement Axle
    On a trailer axle there are a few measurements that you can take. Take a look at the picture I have included for reference. The "A" measurement is the hub face to hub face measurement. The hub face is the surface of the hub where the wheel bolts to. The "B" measurement is from the center of one spring seat to the center of the other spring seat. We have numerous 3500 pound axles included some axle-less systems. I have included a link to them for you. The axle-less systems have built...

  • 6k Leaf Spring for a Forest River Toy Hauler
    Are you sure you aren't exceeding the capacity of your trailer? Going with higher rated springs will give you additional spring capacity but will not increase the overall capacity of your trailer. The only way going with new leaf springs like part # e64SR will fix the sag is if your current 6k springs are worn out. These measure 24-7/8 inches. You would need to unweight your current axle and measure the length. If your current springs are around 25-1/4 inches long these would work well.

  • Recommended Clearance Between Tire and Trailer Frame Rail
    The minimum distance between the inside of a tire and the frame rail depends a lot on the setup of the trailer. But as long as the tire and the frame don't touch you would be fine. It's hard to give an exact figure as trailer setups can vary and some trailers may have more side to side movement which would call for more clearance. If the suspension is good on the trailer and not worn out I would go with at least 1-1/2 inches to be on the safe side. Some might get by with 1 inch but I...

  • How To Find Replacement Slipper Leaf Springs For Older Enclosed Trailer
    The best way to find replacement springs for your trailer is to know the capacity of the axles on your trailer. The axle may have a plate that has the capacity on it. If you are not able to find that information you may be able to tell the capacity by the size of the axle. For a 1000-2000 lb axle the diameter is typically 1-1/2 to 1-3/4 inches. A 3500 lb axle are usually 2-3/8 inches diameter and 6000 to 7200 lb axles are 3 inches diameter. An 8000-lb axle will be 3-1/2 inches diameter....

    The Universal Group 6-Leaf Double-Eye Spring # e64SR referenced in your question is designed for 7,000 pound axles like what you have on your trailer. Most likely this will work great as a replacement, however I cannot be sure that it is a direct replacement for your current leaf springs.

  • Compressed Fender Clearance for Trailer Between Tire and Fender
    Generally speaking you will want to have 3 inches from the top of your tire to the fender of your trailer when the suspension is fully compressed to accommodate for suspension travel. Having a little more wouldn't hurt, but I wouldn't recommend any less than 3 inches. If the suspension was fully compressed and you have 1 inch of clearance from the tire and fender you would be good to go.

  • Can a 7k Rated Leaf Spring be Used on a 6k Rated Trailer Axle
    A 7,000 lb trailer spring can be used on a 6k rated axle but you should note that this will not give you more capacity. A trailer setup is only rated as high as it's weakest component. So while you may have 7k of spring rating with the # e64SR, you would still only have 6k of axle rating.

  • Distance Between Hangers for Triple Axle Trailer Where Springs are 27-1/4 and Equalizers are 6-1/4
    The spring will be attached directly to the hanger closest to the front of the trailer. The back of the spring will be connected to an equalizer which will then be attached to a hanger. If the equalizer is 6-1/4 inches long, center to center, and the mounting hole on it is in the center, it will be 3-1/8 inches beyond the center of the rear eye hole. So, if the spring is 27-1/4 inches from eye center to eye center, add 3-1/8 inches to get 30-3/8. I would then add a maximum of another inch...

  • How to Measure Spring Length and Determine the Correct Replacement Springs for a Trailer
    Measuring the distance from the center of one eye on your original springs to the center of the other eye will give you a general idea of the length of the new springs you need. Your springs may measure slightly longer due to wear so you will want to select a spring that is slightly shorter and matches the capacity of your trailer axle. Adding springs to your trailer that have a higher capacity than the axle capacity or the capacity of the hub and drum components is not recommended. You...

  • Can a Heavier Leaf Spring Be Used on a Tandem Axle Trailer with Lippert Axles

You can go with a heavier leaf spring like you mentioned but please keep in mind that this will not increase your gross vehicle weight rating (GVWR) and it will make the ride stiffer.

  • Changing Tire Size and Axle Spacing on Tandem Trailer
    Trailer leaf springs first need to be rated for the weight load on them and be of the appropriate length to fit the hanger spacing, equalizers and shackle straps. If you are putting much larger tires on the trailer you may have to reposition one axle to provide enough space between the front and rear tires. The minimum distance between front and rear tires on a tandem axle trailer is 1-inch (when the suspension is under load). If you went with shorter springs and longer equalizers then...

  • Can I Use Heavier Rated Leaf Springs on Trailer Without Causing Damage
    You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part # e64SR measures 24-7/8" eye to eye. The only thing you may notice is that the ride may be a bit stiffer with the heavier rated springs. Please keep in mind upgrading to a 8,000 lb spring may require you to switch over to slipper springs instead of double eye springs. Which is...
