Hook End Slipper Spring

Part NumberABCDEF

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.

Slipper leaf springs attach to hangers that are welded onto your trailer. The eye of this spring will attach to the front hanger with a suspension bolt. The hooked slipper end of the spring will slide into the rear hanger. If you have a tandem- or triple-axle trailer, the slipper end will slide into the equalizer that connects multiple springs. The shape of the slipper end of a leaf spring may vary slightly due to differences among trailer manufacturers. Because of this, it's important to check your leaf spring's slipper end before purchasing a replacement spring.

To mount this spring, you will need hangers, a suspension bolt, and possibly a spring keeper bolt, depending on the design of the rear hanger. If you are simply replacing a spring, you may still have hangers welded onto your trailer, but it would be wise to replace the bolts as they can experience wear. It is also 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.

Nice job "e-Trailer"; received this "heavy" order very promptly; did not expect it so quickly in view of how other retailers/ manufacturers/ on-line businesses are behind in fulfilling orders. Packages (3) came all intact, well packed and product received in great condition. The order included: > 5-Leaf Slipper Spring w/ Hook End for 6,000-lb Trailer Axles (2) > U-Bolt Kit for Mounting 8,000-lb, Round Trailer Axles - 8" Long U-Bolts (2) > Tandem-Axle Trailer Equalizer Kit for 2" Slipper Springs - 10-1/8" Long Equalizers (2) > Dexter Nev-R-Adjust Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 6K (2) > Mounting Bolts and Hardware for 12" Brake Assemblies (2) > Bearing Buddy Bearing Protectors - Model 2441SS - Stainless Steel (Pair) (2) > Bearing Kit, 15123/25580 Bearings, GS-2125DL Seal (4) > Optronics LED Combination Trailer Tail Lights - Submersible - 40 Diodes - Driver and Passenger Side. These items are being utilized in the total suspension replacement of a 10,000 gvwr tandem axle trailer. Good sized job for a DIY'er. I expect that it will give my JD 2038 tractor a smooth and safe ride as it is towed/ hauled down the highway. Thank you. I would/will strongly recommend to a friend/relative or associate. ( I'd take a picture of the "project", but there is a vicious rain storm occurring outside; perhaps one or two pics to follow at a later time). 812008

I had ordered some parts online to rebuild the suspension on one of our trailers. Customer service called me a short time later to inform me that they were out of stock on some items, they asked if it was possible to substitute some items. She was able to find the exact parts I needed in a different kit. The parts came within 3 days, very well packed, and they fit perfectly! This is the 3rd time I've ordered from etrailer and they have exceeded my expectations every time. EXCELLENT customer service and quality parts. 345117

Springs arrived after a couple of days. I have never had an item better packed! Springs fir my trailer no modifications as well as U bolts. I wish I had thought to get new hanger bolts as these will be needed. Do not order your springs without new shackle hanger bolts! 321304

  • Which Trailer Suspension Hanger Kit Do I Need For 27" Long x 2" Wide Slipper Spring On 6000-lb Axle
    To mount your 27" long slipper springs # SP-160275 you'll need to choose between a kit for single axle trailers or a tandem axle trailer. If you have a single axle trailer you'll want to use the Single-Axle Trailer Hanger Kit for 2" Slipper Springs - 3-3/4" Tall Front # APS6SE. If you have a tandem axle trailer you'll want to use the Tandem-Axle Trailer Hanger Kit for 2" Slipper Springs - 12" Long Equalizers # APT6SE.

  • Recommended Replacement Leaf Slipper Springs for 27-1/4 inch Leaf Slipper Springs
    Yes, what you described sounds exactly like a leaf slipper spring. Since you want to go by the eye-to-eye, or in your case open-eye, measurement I recommend the 5-Leaf Slipper Spring w/ Hook End for 6,000-lb Trailer Axles # SP-160275. This leaf slipper spring is rated for 6,000 lbs and has an eye-to-open-eye measurement of 27 inches. The extra 1/4 inch that you measured is nothing to be worried about since leaf springs can tend to stretch out a little bit over time. I am attaching a...

  • Recommended Slipper Spring Suspension for 10,000 Pound Trailer
    For Slipper Springs to install on your trailer that will have a maximum load of around 10,000 pounds, I recommend either the 5-Leaf Slipper Spring w/ Hook End for 6,000 pound Axles # SP-160275 or the 4-Leaf Slipper Spring for 5,000 Pound Axles # SP-231275, depending on the actual axle capacity for your trailer. Then for a hanger kit, which will work for either of the Slipper Springs mentioned above, I recommend the Tandem-Axle Trailer Hanger Kit for 2 Inch Slipper Springs # AP216-H202....

  • Replacement Slipper Spring Leaf Springs with 2 Inch Width and 27 Inch Length
    Slipper springs come in 1-3/4 inch, 2 inch, 2-1/2 inch and 3 inch widths. You most likely have a 2 inch spring. The number of leafs isn't the issue, but rather the weight capacity of the spring. We do have one spring that is 2 inches wide and 27 inches long and it is # SP-160275 which is for a 6,000 lb axle. For a different capacity, if you can tell me the measurement of "B" in the attached photo for your springs, and the capacity of your axle or total trailer weight capacity and...

  • How to Determine the Correct Slipper Spring for 6,000 lb Axle
    The slipper spring we carry for 6,000 lb axles is the 5-Leaf Slipper Spring w/ Hook End # SP-160275. To figure out if this spring is going to work for you there is a measurement you will need to take. If you look at the accompanying diagram you can see that "C" is 27 inches. This is the length from the center of the eye to the end of the spring with the slipper; you can measure your current slipper spring to see if you have a similar measurement, keeping in mind that the current spring...

  • Single Slipper Spring for Tandem 6000 Pound Axles 2 Inches Wide
    To determine the appropriate replacement slipper spring you would need there are a few measurements that are crucial. In order to get these measurements the current spring cannot have a load on it. If you have already removed the slipper spring from the trailer that works great. Or you can measure while it is on the trailer, just make sure that when you jack the trailer up you do so by the trailer frame. Also, make sure it is safe and secure before taking your measurements.

  • How Are Slipper Springs Attached to Equalizer and Hangers

I have attached a diagram of how slipper springs are setup. I have also attached a very helpful article that explains slipper spring setups.

  • 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.

  • Recommended 27 inch Leaf Spring for my Trailer
    If you are looking for a Leaf Spring that is 27-3/4 inches long, the closest that we offer in length is 27 inches. If your springs are worn, it is possible they were originally 27 inches long and have flattened out over time. We have a Double-Eye 4-Leaf Spring # SP-210275 that is rated for 3,500 lb Trailer Axles. This spring measures 1-3/4 inches wide and the leaf thickness is 3/8 of an inch. We also have the 5-Leaf Slipper Spring with Hook End # SP-160275 which is rated for 6,000 lb...

  • How to Determine Hanger Spacing on a Tandem Axle Trailer with 6K Axles and Slipper Spring Suspension
    The hanger spacing is going to depend on a few things including the spring measurements and the equalizers being used. But if you were using spring # SP-160275 the distance between the hangers would be around 29-3/4 inches. However this is using hanger kit # AP202-H202 with 10-1/8 inch equalizers. If you were using kit # AP216-H202 the hanger spacing guideline would be 31-1/2 inches because the equalizers are longer. So you can see that it changes depending on the components being used. Also,...

  • Does Tandem Axle Slipper Spring Hanger Kit # APT6SE-36 Work with Springs that are 2 inches Wide
    We have one 6,000 lb axle rated slipper spring that is 2 inches wide. For that you would want the part # SP-160275 that is 27 inches long. The ends of this spring are hooked but do not come all the way back around like a C shape like what it sounds like you have. However, both styles are acceptable and will install in the same way.
