Video Transcript for Redline Trailer Suspension - Leaf Spring Suspension - APUBR-10 Review

Today we're going to be reviewing part number APUBR-10. This is Redline's U-Bolt Kit for mounting 2,000-pound round trailer axles. Its going to attach the trailer axle to your leaf springs. It's going to include four 4 1/4-inch-long U-bolts. It's going to include two U-bolt plates for 1 3/4-inch springs and it's going to include eight 3/8-inch hex nuts. Spring seats are required for mounting the axle to the leaf springs.

Those are going to be sold separately. This is designed to fit axle diameters of 1 3/4 of an inch, which is going to be your typical 2,000-pound axle. If we take a measurement of this right here, which is our U-bolt, measuring from the bottom of the cross member to the bottom of the bolt posts, it's going to give us that measurement of 4 1/4 of an inch. The area in between the bolt posts is going to measure 1 3/4 of an inch, so that's where we're going to get the spring width fitting from. Then the actual threaded portion of the U-bolt is going to give us a measurement of 1 and 7/8ths of an inch. The diameter of each one of these bolts is going to measure 3/8ths of an inch and all U-bolts are going to be the same measurement. The plate is going to give us a measurement of 3 1/2 inches by 3 1/2 inches and it is designed to fit the U-bolts. You're going to get two plates, four U-bolts and then eight nuts, so all the hardware that you need is included. That's going to do it for today's review of part number APUBR-10.

This is Redline's U-Bolt Kit for mounting 2,000-pound round trailer axles. .

Just what I needed to re-mount a 2000 lb. trailer axle. I bought a used boat trailer, and the previous owner had rigged it with some oversize U-bolts. The trailer has a standard 2000 lb. axle and leaf springs. The plates mated with the stud on the leaf springs perfectly and the bolts fit fine. Shipping was fast and I had the parts a few days after I ordered them. 54264

this ujoint kit appears to be complete however the spring seat is not a kit and only comes with just the one. So you need to know to order 2. this is has cause me a delay since I had to order another. The info should be there to warn the buyer they need a quantity of two or come with two if it's sold as a kit like item APUBR-10 ---the ubolts. 633208


Comments

As stated in the product description, the spring seats are sold separately.

Did not end up using, as the previous U-Bolts were still in good shape and had nylock nuts. Be aware that these have 24 TPI threads, not the expected 16 TPI. This is published in the description on the web, I did not read all of the words that were so carefully written. etrailer did everything right on their end. 139666


Comments

No problems with this or the other parts I used to convert to spring over configuration. I recommend etrailer and will use them next time I change my rig.

After purchasing an order of springs, shackle kit, U-bolts, bearing kit and a new Pro jack for a trailer repair I discovered a week delay in shipping due to one of the items on back order. (Email the day after I ordered informing me of the delay) A call to Angie K. On that Sunday!!!! And she had an in stock item to replace it and had my order on its way Monday morning , Thank You Angie everything sent was what I ordered and correct. Communication was great and they did what they said they would, Good prices and free shipping on my orderThanks again 722576

The parts arrived soon after I ordered them and all the parts appeared to be for good quality. I installed the parts on my old snowmobile trailer that I was rebuilding. I sometimes use the trailer to haul some heavier loads that were well beyond the rating of the old springs and that took a toll on them. These new 2000 lb spring are working well for these heavier loads. I used the Wet Equalizer Bolts with Locknuts and Grease Zerks to mount the leaf springs to the trailer with heaver duty shackles, they worked well. 716775

Ask the Experts about this Redline Trailer Leaf Spring Suspension

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


  • Recommended 26 Inch Leaf Springs for 1,500 or 2,000 Pound Trailer Axle
  • When measuring your existing leaf springs, you will want to measure the length from the center of spring eye to the center of spring eye. If you measured a length of 26 inches, then the 4-Leaf Double-Eye Spring # SP-124275 should be a perfect replacement if you have a 2,000 pound axle. To confirm your axle rating, I recommend checking for a plate somewhere on the axle itself that lists its capacity. Even if you do find that your axle has a 1,500 pound capacity, this leaf spring set...

  • Replacement Trailer Axle for a 5x10 Utility Trailer
  • Unfortunately, we do not have any hubs that match the dimensions you provided. The only other option I have for you at this time would be to replace the axle. If you can provide me with the hub face to hub face and spring center to spring center measurement, I can go about trying to find a replacement axle for you.

  • What is the Difference Between Double Eye Leaf Springs and Slipper Leaf Springs
  • The difference is found in the application. The Slipper Spring styles, like part # SP-179275, are intended for use with more heavy duty applications, while the Double Eye styles, like part # SP-124275 are used to provide a more comfortable ride. The part # SP-124275 that you referenced will be the correct fit if your current leaf springs are 26 inches long from the center of the attachments points (usually known as eye-center-to-eye-center). You might also still be needing a U-Bolt...

  • Hub, Leaf Spring, and U-Bolt Kit for 2,000 lb Trailer Axle
  • The Dexter Trailer Axle w/ Idler Hubs # 20545I-EZ-72-15 is designed to fit 2,000 lb trailer axles. If that's what you have then this will fit and the U-bolt kit part # APUBR-10 that you referenced would also work since that's what it's designed to fit. The leaf spring part # SP-169275 is also a 2k axle spring but you'll want to make sure the length matches what you need too. This has an overall lenght of 20-3/8 inch.

  • Recommended Leaf Springs and Hardware for 2001 EZ Loader Boat Trailer With 1560 lb Axle
  • There are different leaf spring lengths available for your axle capacity, so you will need to measure from the center of spring eye to spring eye. We have these 3 options: 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 20-3/8" Long # SP-169275 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 26" Long # SP-124275 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 23-1/2" Long # SP-113275 For your connection to your hangers, you will want the Shackle Bolt with Locknut...

  • Can an Axle Over Under Kit be Made for 1-3/4 inch Trailer Axle
  • If you are okay with removing the fenders or going to a larger one that would probably be your simplest route and the way I would go if I were you. We don't have an axle over under kit for your axle size, but we could piece together one if you like. All you would need for an over-under kit for a 1-3/4 inch round axle would be the U-bolt kit part # APUBR-10 and the spring seat part # TRSS175. You would need two of the spring seats. Then for a 14 inch wheel and tire we have the part...

  • Is There An Axle Flip Kit for a 2,000 Lb 1-3/4 Inch Diameter Axle
  • I do have all of the components you will need to flip the axle on your tent trailer but there is not an all inclusive kit per se to do so. However, the kits are pretty basic as all they include are u-bolts, tie plates, and spring seats. For your 1-3/4" diameter axle, I recommend using the U-Bolt Kit part # APUBR-10 with the Spring Seat part # TRSS175 (2). The only difference between these two parts and a kit like the Dexter Trailer Springs Over-Under Conversion Kit is that the spring seats...

  • Thank you for your email answering my questions on your axle. I have the information to help you with your tandem axle application. Your current axle is not a standard size, so I recommend replacing your current axle as well. There are two routes to go for this, the more traditional style or the axle-less.

  • Parts Needed to Flip Axle on a Pop up Camper
  • I have exactly what you need, but it will have to come in the form of a couple parts pieced together because an over-under conversion kit or "axle flip kit" as some people call it isn't available for the smaller 1-3/4 inch round axles. To move your leaf springs above your axles, you will want the following parts: Qty 2 - Spring Seats # TRSS175 Qty 1 - U-Bolt Kit # APUBR-10 The spring seats will be welded to the opposite side of the axle as the current spring seats. You may not need...

  • Replacement Trailer Suspension Components
  • In a typical leaf spring trailer suspension a spring seat like # TRSS300 is welded to the axle but the u-bolt plate is not. The u-bolt plates are bolted around the axle and leaf spring and these hold the spring in place on the spring seat and to the axle, as noted on your photo. You can also refer to the linked article on slipper spring suspensions for more on the details of how these parts work together and on how to measure. You'll want to completely remove one spring from the suspension...

  • Spring Hanger and Axle Diameter Measurements for Installing Leaf Springs on Single Axle Trailer
  • In the attached diagram the A measurement is actually the distance from the center of the spring hangers for a single axle trailer. The spring eye to spring eye measurement for your leaf springs will be slightly different. The B measurement that you see is simply the distance between the center of the axle and trailer frame. I have attached another diagram from the Single-Axle Trailer Hanger Kit for Double-Eye Springs # APS3 product page to help demonstrate this. If you have an axle...

For the leaf spring, I recommend using the 3-Leaf Double-Eye Spring part # SP-219275. For the suspension kit, I recommend the Single-Axle Trailer Hanger Kit for Double-Eye Springs part # APS4. For the u-bolt kit, I recommend the U-Bolt Kit...

  • Will Slipper Springs be Installed Above or Below New Dexter Axle
  • If you are installing the Dexter Idler Trailer Axle w/ Hubs # 20545I-EZ-60-10 with the U-Bolt Kit # APUBR-10 on your Harbor Freight trailer you will install the slipper springs, either # SP-039275 or # SP-179275, below the axle like in the linked installation video. This axle will work as a replacement, though I do recommend verifying your current axle has the same 48" spring-center-to-spring-center length and 60" hub-face-to-hub-face length.

  • Recommended Springs and Ubolt Kit for 1993 Tacker Trailstar Boat Trailer
  • Sounds like the 3-Leaf Double-Eye Springs # SP-219275 are what you are looking for. They have an eye to eye distance of 25-1/4 inches, a width of 1-3/4 inches and are rated for 2,500lb trailer axles. The ubolt kit # APUBR-10 should provide you with enough clearance. This ubolt kit is designed for 1-3/4 inch round axles and are 4-1/4 inches long and the ubolt post has a diameter of 3/8 of an inch. See the picture I've attached.

  • Replacement Parts to Rebuild Trailer Suspension on 1976 EZTrail
  • All of the products you listed will work together just fine. Keep in mind, if your current springs are not 26 inch springs, like the # SP-124275 you referenced, your hangers, # APS4, will not be in the exact same position as your current ones. When repositioning everything the most important factor is keeping the axle in the same location it currently is. The U-Bolt Kit # APUBR-10 is correct for a 2,000 pound axle and the Shackle Bolt # 166081 will work too. It's hard to tell by the...

  • Parts Needed to Do an Over-Under Kit on a 1-3/4 inch Trailer Axle
  • When you use an over under kit like the part # K71-385-00 you end up gaining a lift that measures the diameter of your axle, plus the spring seat, and the thickness of your leaf springs. You will need to measure those items on your trailer to determine the amount of lift you would need. Since we don't have a kit designed to fit a 1-3/4 inch diameter axle, and since you aren't completely sure that is the diameter of your axle you will need to verify this before I can piece you together...

  • Parts Needed to Move the Spring Seat of the Dexter Axle part # 20545I-EZ-60-10
  • The axle part # 20545I-EZ-60-10 that you referenced has a 1-3/4 inch diameter and the # K71-384-00 is designed for a 2-3/8 inch axle so that would not work. What you could use is the # TRSS175 as it is a spring seat confirmed to work on this diameter axle. For a U-bolt kit you would want part # APUBR-10. You should have no problem using your current leaf springs with this axle as well.

  • What Torque Should Be Used For U-Bolt Nuts On Trailer Suspension
  • If the U-bolts are 9/16 inch diameter, the torque specs should be between 65 to 95 foot lbs. If the U-bolts are 3/8 inch diameter, the torque should be between 30 and 50 foot lbs.

  • Over Under Kit Recommendation for 1-3/4 inch Axles
  • I wish we had something we could offer you, but none of the spring seats we offer are designed to fit a 1.9 inch diameter axle. The closest we have is the 1.75 inch spring seat like part # TRSS175 which wouldn't work unless you happened to incorrectly measure your axle diameter and you do have 1-3/4 inch axles. The rest of the parts you would need would come in the kit part # APUBR-10.

  • Hanger, Leaf Spring, and U-Bolt Kit Recommendation for Dexter Axle # 20545I-EZ-60-15
  • The Dexter axle part # 20545I-EZ-60-15 is a 2,200 lb axle so for springs you'd want the 2,500 lb spring part # SP-219275 which is the closest we offer to a 2,200 lb axle spring. Then for a u-bolt kit you'd want the part # APUBR-10. The part # APS4 would be a great single axle kit to use as well.

  • Recommended Leaf Springs and U-Bolt Kit for New Trailer Axle
  • The Dexter Idler Trailer Axle w/ Hubs # 20545I-EZ-60-10 referenced in your question is a 2,200 pound axle. In order to choose the correct size leaf springs, I recommend measuing the length of your existing/previous set. For example, the 3-Leaf Double-Eye Spring # SP-219275 has a length of 25-1/8 inches from the center of spring eye to the center of spring eye. You will want to get as close as you can to the length of your previous leaf springs, keeping in mind that they may have stretched...

  • Parts Needed to Install 2,000 Pound Round Axle Under Leaf Springs
  • In order to mount the round 2,000 pound axle under your trailer's leaf springs, we will need to piece together an over-under kit for the 1-3/4 inch outer diameter of the axle. The Dexter Trailer Springs Over-Under Conversion Kits that you referenced are made for axles with a 2-3/8 inch round axle # K71-384-00 or 3 inch round axle # K71-385-00. The Dexter 2,200 pound straight axles have a 1-3/4 inch outer diameter. I have attached a link to all of the 2,000 pound axles we offer. To mount...

  • Adding a Brake Axle to a 48 Inch Wide Home Made Travel Trailer on Harbor Freight Frame
  • What you could do is use an axleless system # A35RS545E which comes with everything except a brake controller. The only issue is that you would need to also replace the tires and wheels with something like # TTWA13BSM since the kit has a 5 bolt pattern and your trailer has a 4 on 4 pattern.

  • With an unkown axle it is hard to know what it's capacity would be. Plus a trailer's capacity is more than just the axles it uses. You have to consider the suspension, the frame, coupler, brakes etc. The part # 20440I-EZ-60 that you referenced would bolt right up to your trailer and would give you 2,200 lbs of axle capacity. But for the overall capacity of the trailer you need to go with the lowest rated component as the overall capacity. You would also want the # APUBR-10 for new...

  • U-bolt kit # APUBR-10 is the only one we carry that fits a 1-3/4 inch diameter trailer axle. You would have to change the springs to 1-3/4 inch wide springs to use this kit. A larger u-bolt kit would not work because it can cause damage. To determine if we have springs that will work for your trailer I will need to know the type of springs you have, double-eye or slipper springs, and the measurements. A 1-3/4 inch diameter axle likely has a 2,000 pound capacity so we would be looking...

  • The first thing you will need to determine is what the weight capacity of the trailer is. There should be a plate or sticker on the trailer or on the axle with those numbers.

  • Parts Needed for Over Under Axle Kit on 1-3/4 inch Diameter Axle

  • Some trailers have the leaf spring stack above the axle and some have it underneath. You can move the stack to the top of the axle but you will have to weld on new spring seats to the top of the axle. Use # TRSS175 for a 1-3/4 inch round axle. It will raise the height of the trailer some but you need to be aware that it also raises the center of gravity. That makes the trailer more susceptible to sway.
