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.

  • Will the 23-1/8" 3-Leaf Double-Eye Spring for 3,500-lb Trailer Axles Replace a 4-Leaf Spring
    The number of leaves won't matter when going from a 3-Pack to 4-Pack or when going from a 4-Pack to a 3-Pack, so long as the weight capacity is correct there won't be an issue. The leaf thickness can vary from manufacturer to manufacturer which is why you see some springs with the same rating but different number of leaves. The 3-Leaf Double-Eye Spring for 3,500-lb Trailer Axles part # e59SR only has three leaves but still holds a 3,500 lb rating so as long as this matches the axle capacity...

  • Replacement Double Eye Leaf Spring Recommendation for 23-1/4" Long Leaf Spring
    Thanks for reaching out, we definitely can help you with a replacement double eye leaf spring! For your application I recommend picking up the 3-Leaf Double-Eye Spring for 3,500-lb Trailer Axles # e59SR which measures 23-1/8" center eye to center eye. Be sure to take this measurement without weight on the leaf spring so that it's relaxed and won't be flattened out. It's also important to note that whatever you do to one side of the axle you need to do to the other so you'll want to order...

  • Picking Out Replacement Leaf Spring for 2016 Northwood Nash 24M with 3,500 lb Axle
    So we know you have a 3,500 lb trailer axle based on what you listed but we don't know how long of springs you'd need which is the other piece of info needed. The most common size that most likely is what you need is 25-1/8 inch like what the part # SP-212275 but we do have other sizes too like with the part # e97SR which is 27 inch and # e59SR which is 23-1/8 inch. You'd want to jack up the frame of your trailer enough that there isn't a load on the springs and measure length from spring...

  • Does 3,500 lb Leaf Spring Need to Have Same Number of Leaves as Original
    Yes, you can replace your 3,500 lb 7-leaf springs with leaf springs that have 3 or 4 leaves because the weight rating is the same. The number of leaves isn't a determining factor; for example, there are 4-leaf springs for both 2k and 6k axles. So you simply need springs with the correct rating for your axle, as well as the right length. For that, you'll want to measure the length from center-to-center of the spring eyes, taking into account you current leaf springs will have elongated...

  • Is There a Difference Between 23-1/8 Inch 3-Leaf Double Eye Spring For 3,500 lb Axle
    Everything about the pair of leaf springs you mentioned, from their 3,500 lb weight capacity, to the 23-1/8" center eye to center eye length, to 1-3/4" width, is the same. There is no difference in dimension or quality, so I recommend just going with the least expensive option between the two: - 3-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 23-1/8" Long # e59SR or - 3-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 23-1/8" Long # SP-216275

  • Determining The Correct Replacement Leaf Springs For A 2021 Keystone Passport Grand Touring TT
    You could potentially replace your leaf springs with a larger capacity spring but will need to match the length of your current leaf springs to avoid having to remove and reinstall the hangers and rest of the suspension system, which is a giant hassle and a lot more costly than just replacing the springs. If you have double-eye leaf springs you'll need to measure from the center of one eyelet to the center of the other. If you have slipper springs then you'll need to measure from the...

  • MORryde Shock Absorbing Equalizer For a 2018 Keystone Bullet 277BHSWE
    The MORryde 14-3/4" Shock Absorbing Equalizers # MR34AR will allow you to upgrade your factory equalizers. These are specifically designed to fit with the 42" axle center spread you have on your Bullet. I recommend also changing out for the Wet Bolt Kit # MR46ZR which will allow the suspension to more easily move throughout its range. I was able to find your 2018 Keystone Bullet 277BHSWE has 3,500lb axle but I could not get an exact part number for the replacement leaf springs. I have...
