Video Transcript for Redline Trailer Suspension - Leaf Spring Suspension - APS1 Review

Today we're going to be taking a look at part number APS1. This is the single-axle trailer hanger kit for double-eye springs from Redline. This system is designed to attach two leaf springs, which are going to sold separately, to your trailer frame. You can use the table on the product's product page to help determine the hanger location based on the type of leaf springs that you have. This is designed to achieve 4 1/4-inch or 4 1/2-inch clearance between the trailer frame and the axle, again, depending on your axle size. It's going to include two 1 1/2-inch-tall front hangers. It's also going to include two 7/8-inch-tall rear hangers and they have the steel bushings on the inside.

They also have indicators right here on the top that's going to indicate which side is the top. The flat portion is going to face the front of the trailer. The open end is going to face the rear of the trailer and then the top portion is going to be the portion that needs to be welded. It's also going to come with four 3 1/8-inch-long shackle straps, six 3-inch-long by 9/16-inch-diameter shackle bolts, as well as the 9/16-inch-diameter nuts. This is designed for use on trailers with single 2,000-pound to 7,000-pound axles and it does not include the components for mounting the axle to the springs. That's going to do it for our review of part number APS1. This is Redline's single axle trailer hanger kit for double-eye springs.

Phil, thanks for your business and your review. Since the required U-bolt lengths and diameters vary from axle to axle, the mounting components are sold separately. The U-bolt kits may be found at this link:

I have purchased several items from etrailer and have always been very satisfied with there parts and there service. I have never had the pleasure of talking with any of there reps,because they do such a great job of describing their parts with videos and knowledgeable people it makes the job easy. When you live in a small town you can't just go down town and buy a new set of spring hangers or a new spring, but with the push of a button you can usually find what you need and it is priced fairly.I am a very satisfied customer. keep up the goog work etrailor 359032

Ask the Experts about this Redline Trailer Leaf Spring Suspension
Do you have a question about this Trailer Leaf Spring Suspension?


  • 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...

  • Comparing the Single-Axle Trailer Hanger Kits for Double-Eye Springs APS1, APS2, and APS3
  • When choosing between the Single-Axle Trailer Hanger Kit for Double-Eye Springs part # APS1, part # APS2, and part # APS3 it will be best to use the one that has measurements that most closely resemble what is already on your trailer. For example, if your rear leaf spring hangers are 7/8" tall or shorter than you would want to use part # APS1 but if they are taller then this you would want to use part # APS2 or part # APS3. The only difference between the two latter kits is that part #...

  • Hanger Spacing Dimension Used for Leaf Spring Part # SP-124275

  • 3,500 lb Axle Suspension and Leaf Spring Install Hardware Recommendation
  • For a 3,500 lb capacity trailer axle with idler hubs that have a 5 on 4-1/2 inch bolt pattern you would want the part # 35545I-EZ-89. If you need brake hubs you would want the # 35545E-ST-EZ-89. These axles have a distance of 89 inches from hub face to hub face and a distance of 74 inches from spring center to spring center. For a 3,500 lb rated leaf spring you would want the # SP-212275, then for a hanger kit you would want # APS1 and then for U-bolt kit to hold the axles to the springs...

  • Differences in the Redline Single-Axle Trailer Hanger Kits, # APS1, #APS2, and # APS3
  • The APS1, APS2, and APS3 are all suspension kits for single-axle trailers with 1-3/4-inch double-eye springs. They are designed for use on trailers with single, 2,000-lb to 7,000-lb axles. The difference in the kits are in the rear hangers and the shackle straps. The Redline Single-Axle Trailer Hanger Kit, part # APS1, uses the Redline Rear Hanger, part # 30-20, which uses a steel bushing and is .91 inches tall. The shackle straps are the Shackle Strap, part # TRSL313, which are...

  • Are there Bolt-On Hangers for Trailer Leaf Spring Suspension
  • We do have a couple of bolt-on spring hangers # CE14017G and # CE14016G but they are designed for slipper springs and not double-eye springs like # SP-124275. Its not likely that professional welder would charge that much. You might be able to find one locally via an iron workers union near you. For u-bolts for your 1-1/2 inch square axle you can use # SP01-120 for 2 u-bolts and 4 nuts. For a u-bolt plate you can use # 115983. For a hanger kit you could use # APS1. Now what you could...

If you are replacing the springs and hangers you will need to use the same center to center dimension as the original mounting brackets. These springs are designed for a 4,500 pound axle. If you are building a new trailer you will need to determine the weight capacity of the axle you will be using and order springs and...

  • 3,500 lb Axle, Leaf Spring, Wheel and Tire, Hanger Kit and U-Bolt Kit Recommendation for a Trailer
  • The Dexter Trailer Axle w/ Electric Brakes # 35545E-ST-EZ-89 that you referenced is a 3,500 lb axle so you will need to use springs with the same capacity. For that I would recommend the 3-Leaf Double-Eye Spring # SP-220275 that you also referenced. For a single axle hanger kit you would want the Single-Axle Trailer Hanger Kit # APS1. For a wheel and tire combo that you could run all around your trailer you could get the Karrier ST205/75R15 Radial Trailer Tire with 15" Galvanized Wheel...

  • Are Bushings for Trailer Suspension Spring Hangers Required
  • Bushings do not always have to be used. Springs typically have bushings or they will use wet bolts depending on which part of the suspension system it is but not always. The bushings limit the wear on the suspension components. There are just different designs. Kits # APS2 and # APS5 use the same 7/8 inch hangers and it is those hangers that come with the bushings. I have included a link to our help article on double-eye trailer suspension for you.

  • Trailer Leaf Spring Hanger Spacing Measurements for Single-Axle Trailer Hanger Kit APS1
  • The measurements given on the hanger kits including # APS1 are a guide only. The actual measurements will vary and to get the suspension set up correctly you would first mock up all the parts without permanently installing them. Then once the parts are in the proper positions they can be permanently installed. Basically the charts and measurements given on the hangers kits are good starting points but will not work for every situation.

  • What Is The Proper Hanger Spacing For A 3 Leaf 1,750 lb Capacity Leaf Sping
  • The spacing of leaf springs varies depending on how many axles are on your trailer and the position of the spring. For a 3 leaf, 1,750 lb spring like part # PR3 the hanger specifications in the Redline Trailer Supplies Catalog are as follows: Single axle - 25-3/4 inches Tandem axle - A=29-1/2 - B=29-1/2 Triple axle - A=29-1/2 - B=34 - C=29-1/2 The recommended hanger kit for a single axle trailer is Single Axle Trailer Hanger Kit, part # APS1, or part # APS4.

  • Can a Coleman Fleetwood Pop Up be Converted From Slipper Spring to Double Eye
  • If you wanted to convert your slipper spring suspension to double-eye suspension you certainly could. It would be just a matter of changing springs and hangers. You would need to go with a leaf spring that is rated for the weight of your trailer when it is loaded an ready to go. I attached a page that has all of the double eye springs we offer. At the top is a chart that has all of the springs and their capacities. Select the capacity you need and then on the product page the correct...

  • I do have a few options available for you however, we currently do not sell torsion axles. You have two options to consider for your trailer, the Timbren axle-less suspension and the Dexter straight axles. As you have a gross trailer weight (GTW) of 3,000 lbs. I recommend using a 3,500 lb setup. The Timbren System will provide you with a much easier method for converting from torsion springs in addition to containing fewer components.

  • Leaf Springs, Hanger Kit, and U-Bolts for a 2 Inch Square Trailer Axle
  • Since you do not know the capacity of the trailer axle then you can't go by the capacity of the springs. If the axle is rated for 2,000 pounds and the springs for a 3,500 pound axle then you would still be limited to 2,000 pounds. If you have the inner and outer bearing numbers then that will help to determine what the likely axle capacity is. Since you want to replace the hangers as well as the springs then it doesn't matter which springs you choose. If the axle does end up having...

  • Leaf Springs and Hanger Kit for 2,000 Pound Dexter Axle
  • You could mount springs to the top of Dexter axle # 20545I-ST-60-15 but you would have to weld on new spring seats # TRSS175. The springs seats that come with the axle are welded to the bottom. You can't flip the axle over because then the natural bow in the axle would be facing the wrong way, the tires would stick out at the bottoms, and the capacity would be diminished. The taller a trailer is the more susceptible to sway it becomes because the center of gravity is higher. Just something...

For a 3-inch round axle rated between 5200- and 7200-lbs use part # TRSS300; for a 2-3/8-inch diameter 3500-lb axle use part # TRSS238; for a 1-3/4-inch diameter 2000-lb round axle use part # TRSS175.
