Video Transcript for Redline Trailer Suspension - Leaf Spring Suspension - APS5 Review

Today we're going to be taking a look at the Single Axle Trailer Hanger Kit for double eye springs. This kit includes front hangers, it's going to come with your rear hangers, it's going to come with your shackle straps, and it's going to come with your necessary hardware for mounting the springs to your 2,000 pound to 7,000 pound single axle trailer frame. Now components for mounting the axle to the springs are sold separately. This kit simply attaches two leaf springs to your trailer frame. There is a helpful table that's located at etrailer.com on this product's product page. That really helps determine the hanger location based on the type of leaf springs being used. When this kit is installed it's going to achieve about 4 3/4" or 5 3/8" of clearance between the trailer frame and the axle.

That's going to be dependent on the axle size. The components included with this kit are made from a very strong and durable steel construction. We just want to go over some of the components real quick. It's going to come with two 3 1/4" tall front hangers. The hole diameter on this unit is going to measure 9/16".

That goes for the front hangers, the rear hangers, and the shackle straps. The diameter of the bolts, that's going to be 9/16" as well, as well as the lock nuts. Everything is designed to work together. The height measurement of the front hanger is taken from the top of the hanger to the center of that 9/16" diameter hole. That's where we get the 3 1/4" measurement from. There's also going to be two holes located on top.

Those are for spot welds. The kit also comes with 7/8" tall rear hangers. THey're going to have the steel bushings in there. It does say top right here on this side to indicate proper orientation, so it would install like this. Again, 9/16" diameter hole, so the 7/8" measurement is taken from the top of the hanger, which is right here to the center of the hole.

If we do you can see that measures right on 7/8". Then it also going to come with your 3 1/8" long shackle straps. That measurement is taken from the center of one hole to the center of the other. If we put a ruler on there, that's going to measure right around 3 1/8". You're going to get four of those. You're going to get six 3" long by 9/16" diameter shackle bolts, and six 9/16" diameter lock nuts. That's going to do it for today's look at the Single Axle Trailer Hanger Kit for double eye springs.

Used this kit to get rid of the annoying slip springs on my Harbor Freight trailer. Everything fit nicely and the trailer is makes much less noise. I re-made the base-plate these weld onto with some Angle iron I picked up at Home Depot. (See enclosed pictures) All-in-all I am happy with this suspension kit and would recommend if you are doing a similar project. 482522

My 6' x 10' landscape trailer was a homemade by a prior owner. While it was mostly constructed very well, the spring hangers were not correct. The spacing for the springs was also wrong, and it had very little fender clearance. There was also evidence that the spring U-bolts had contacted the frame on occasion. (I do not carry loads anywhere near the 3500# axle rating.) I added an extra set of holes on the front hangers in case the ride height proved to be too much, but I like the way it sits with the stock holes. I don't think I'll be utilizing the extra holes. This kit was just the ticket to increase the suspension travel and fender clearance on my landscape trailer. Now it "sits right"! 527250


Comments

I recently carried over a ton of rip-rap with my trailer. The trailer still had plenty of of axle and fender clearance. This kit has proved to be just the remedy for my landscape trailer.

Perfect. All the parts were in the box and exactly what I needed.. The measurements were right on. My only down was the back order.

That was wrong on there part. After I explained how wrong they did pay for the ground from ups then to ship it faster once they got the parts in.

Just starting the manufacture of an item I finally finished design/layout. Industrial Designer for 20 years before teaching.

Purchased some spring seats, hanger kits, and U-bolt kits. Parts look fine and should work just as well. Thanks etrailer. 179302

Ask the Experts about this Redline Trailer Leaf Spring Suspension

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


  • Axle And Suspension Recommendation For Utility Trailer
  • I think the easiest way to get the parts you need for your trailer is to buy an axle kit that comes with the idler hubs, bearings, races, seals, grease caps, wheel studs, and lug nuts. For the weight you are saying you will be carrying I recommend starting with the Dexter Trailer Axle w/ Idler Hubs, part # 20545I-EZ-72-15. This system has a 5 on 4-1/2 bolt pattern so the tire/wheel combo I recommend is the Karrier ST205/75R14 Radial Trailer Tire with 14 inch White Wheel, part # AM32153....

  • What are the Proper Components Needed to Install the Leaf springs On a Trailer
  • Building a single axle trailer you will need the following items to install leaf springs. I have listed the part numbers for the PR626 Springs next to the items needed. 2 Springs - # SP-256275 2 Front Hangers - # 115917, 1-1/2 inch tall or # 28-5, 3-1/4 inches tall 2 Rear Hangers - # 30-20, with 1-1/2 inch or # 93003-3x, with 3-1/4 inch 4 Shackle Straps - # TRSL313 6 Shackle Bolts and Nuts - # 166081 These components are available in the following Kits. Single Axle Trailer...

  • 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.

  • Orientation of Rear Hanger Installation on a Trailer with Double Eye Leaf Spring Suspension
  • The portion of the rear hanger with TOP labeled on it will get welded to the trailer frame. I am including a picture of the hangar that shows the top marking and how it is positioned on the trailer. I attached an FAQ on trailer suspension for you to check out also.
    view full answer...

  • Should Suspension Shackle Straps Angle Towards the Front or Rear of a Trailer
  • The distance between the spring eyes on center for # SP-212275 is 25-1/8 inches. When using hanger kit # APS5 the distance on center between the hangers with this spring is 25-3/4 inches, a 1/2 inch longer. This is correct. The hanger spacing should be longer and the bottom of the shackle strap should angle towards the front. Once there is weight on the suspension the angle of the shackle will change.

  • Selecting Replacement Front Spring Hanger for 2000-lb Axle
  • If you are replacing an existing front hanger on your trailer you can measure the original hanger to help you select a replacement. The linked article will be helpful. If the trailer is a single axle type then the front and rear hangers do not have to be the same height. You can choose a hanger of the height that provides the appropriate clearance between the axle and frame.

  • Distance Between Hangers for the # APS5 kit When Used with Leaf Spring # SP-212275
  • Your logic about the shackle leaning the correct direction is spot-on, but the thing about leaf springs is that they flatten out when weight is put on them. So although the # SP-212275 you referenced is 25-1/4 inches long when uncompressed it should flatten out once installed and the weight of the trailer is on it so that the angle of the shackle strap will be correct. The best way to use the dimensions recommended for spring hanger kits is to use them as a guide. When everything is...

  • Trailer Axle, Springs, U-Bolt Kit, and Hanger Kit Recommendation for a 3,500 lb Utility Trailer
  • First let's start with the axle. For a 3,500 lb axle we offer the part # 35545I-EZ-89. This comes with idler hubs with a 5 on 4-1/2 inch bolt pattern. From hub face to face this axle measures 89 inches and between the two spring seats measures 74 inches. Your trailer will have to be compatible with both dimensions. For a U-bolt kit to mount the axles to leaf springs you would want the part # APUBR-1. For leaf springs you would want the # SP-212275. For a hanger kit you would want part...

  • How to Prevent Trailer Sway on a 26 ft 2011 Starcraft Autumn Ridge Towed by a 2011 F-150 Ecoboost
  • Many times adjusting the way that the trailer is loaded can help minimize trailer sway. Try loading the trailer so that more weight is toward the front of the trailer, and see if this helps. Too much weight in the back of the trailer and a light tongue weight will cause the trailer to sway. You will also want to make sure that your trailer is as close to level as possible. If your trailer is loaded properly and you are towing it level, then I would recommend is adding a weight distribution...

  • Leaf Spring Hanger Options for 8x8 Tilt-Bed Trailer
  • For the springs, I'd recommend the # SP-169275 spring, which is designed for 2K axles and measures 20-3/8 inches from eye center to eye center. If you need a U-bolt kit for this axle, # APUBR-10 will work well. The hanger kit you use will depend on how much space you want between the axle and the trailer frame. Hanger kit # APS1 provides between 4-1/4 to 4-1/2 inches of clearance. # APS3 would give between 4 and 4-1/2 inches of clearance. # APS4 is 5 to 5-1/2 inches and # APS5 is between...

  • Trailer Sways Above 40-50 Miles Per Hour
  • If a trailer is swaying exclusively at certain speeds, rather than in response to passing traffic or gusts of wind, three possible culprits come immediately to mind. First would be the loading of the trailer. If the trailer has insufficient tongue weight (not enough weight at the front of the trailer) sway can be caused. Try loading the trailer so that more of the weight is forward of the trailer axle. Secondly, a bent axle can cause the sway you are experiencing. This might not be...

  • How to Determine the Correct Weight Distribution System
  • I'll start with your last question concerning the trailer brakes - they will not stop your truck. As for a weight distribution system it is important that you have the correctly rated system; I don't what you have but I can tell you how to figure out what you SHOULD have. In order to choose the right weight distribution system you will first need to know your total tongue weight (TTW), which is the tongue weight of your fully loaded and ready to go trailer plus the weight of any cargo...

  • Recommended Suspension Parts Needed To Build A Smoker Trailer
  • Looks like you have quite a project going here. After consulting with other Experts, the first thing I would recommend is a new axle for your trailer frame. It appears the axle you have was originally used on a car and welded to the trailer. I could not recommend any suspension that could safely be used with the axle in your photos. I have attached a help article that explains how to determine the correct axle position. The next thing to consider is that you will have to build your...

  • How Far Apart Should Hangers Be on My Custom Built Trailer With 27" Leaf Springs?
  • Generally speaking you want the distance between your hangers to be about 1/2" shorter than your leaf springs, since your shackle straps will allow for some movement on the springs. The hanger kit you want to use depends on how much clearance you need for your axle. A good kit that will give you about 4-1/2" of clearance from the center of your axle to the bottom of the trailer frame is the # APS5 . This kit contains the front and rear hangers as well as shackle straps and bolts needed...
