Video Transcript for Redline Tandem Axle Trailer Equalizer Kit Review

Today on our trailer, we're gonna review and install the red line tandem axle trailer equalizer kit. Part number AP202. Here's what an equalizer kits gonna look like once it's installed. Now an equalizer kit re-secures both the springs and the equalizer but keep in mind that the leaf springs are not part of the install kit. Our kit comes with the necessary fasteners for re-securing not only the new equalizer but our springs as well. It's got two large shackle bolts and two small slipper bolts. It also comes with the equalizer bolt. This particular equalizer bolt is also greasable.

Here it has a grease zerg to allow us to pump grease into the bolt and it'll spread through the equalizer to give it some lubrication so when it's moving as it goes down the road, it doesn't wear out the bolt. Now with the old leaf spring and equalizer still installed. We can take a look at reasons for replacing your equalizer and springs. For this application, our equalizer is bent up and the center bolt is worn so that the equalizer doesn't shift properly. Here we can see the spring is also been over loaded and the strap is no longer holding the spring pack like it should. Next we'll go ahead and get our old parts out of the way. Now with the old parts off, let's just go ahead and compare them to some of the new parts.

Here we have our shackle bolt that connects the leaf spring to the shackle. We can see the old volt is worn down and it's even displaced some of the metal. You can see it's thinner where it rides on the shackle. The new one will be splined into the shackle so the bolt doesn't rotate and it'll tighten up our suspension because it's not worn like the old bolt. Now for our equalizer bolt we can really get an idea of the excessive wear that was going on. We've got about a quarter inch of metal that's been removed from the bolt from wear.

Now we've got the new parts laid out. Let's go ahead and start installing them. We'll start with our equalizer. Notice here on the outside of the shackle for the equalizer is a square that will line up with the shackle bolt for the equalizer. Get our equalizer into place. Slide our bolt into position and then put the lock nut on the inside.

Now keep in mind as we install our fasteners, we're just gonna install then finger tight until everything is in place. Next we'll go ahead an install our forward leaf spring. We've got our new shackle bolt to hold it in place. Now with our shackle bolt in place, we'll go ahead and install the equalizer slipper spring bolt. Again, the bolt will go from the outside in and install the lock nut. Now let's move to the rear spring. Now we're ready to tighten down our fasteners. We're gonna work the largest to the smallest. Starting here with the equalizer bolt. Make sure you hold the equalizer bolt in place because of the squared section on the outside of the shackle and then tighten it down. Quick tech tip, even though our shackle bolt is splined, I like to hold it with a wrench so that it doesn't put any excessive pressure on the bolt and it strips out when you tightening it down. And just like that, our red line tandem axle equalizer kit, part number AP202 is installed and we're ready to reinstall our axles and hit the road.

My 20 year old trailer (that I use for my Lawn Business ) needed new axles and while shopping for parts I found these Equalizers
I was impressed with the price.
I received them a few days which was great since I needed my trailer back on the road quick
The new parts installed perfectly
It was nice that all the hardware was included.
The old parts where severely worn so now
the trailer rides great and I have the comfort of mind that my complete axle assembly is brand new
I strongly recommend this product




by:

Parts fit perfectly. I didn't receive two of the lock nuts for the wet bolt. But after a quick email to the etrailer rep, they had a packagein the mail and on the way the following day. Very pleased with the parts and service.




by:

Great value for this kit, as its complete with all the needed hardware. I would buy this kit again,and I highly recommend etrailer, they are the best when it comes to service and delivery!!!!




by:

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).




by:

This particular part was the most perfect part for my application and it works like a million bucks!!!!




by:

Maybe add the plastic bushings for the springs to the kit would be great. Everything else was great




by:

Contained ALMOST everything I needed to replace the worn slipper spring equalizers on my trailer. Ended up having to order four TRBU12566 nylon bushings since they were totally worn out, so I had to wait another week for those to arrive to complete the project. Would recommend adding the bushings as a "related product" or putting a set of 4 in the kit.




by:

Perfect replacement fit for my old equipment trailer suspension. Easy to use website made getting the correct replacement parts the first try. Nice heavy duty construction that bolted in exact fit.




by:

Was easy to use the web sight and find the correct parts for my 1990 Logan coach horse trailer everything fit perfectly and I’m still on the road thanks to etrailer

  • Does the Center Hole On the Tandem-Axle Trailer Equalizer Kit for 2" Slipper Springs Need a Bushing
    The Tandem-Axle Trailer Equalizer Kit for 2" Slipper Springs part # AP202 uses a 7/8" diameter wet bolt to secure the equalizer to the hanger. It does not require a bushing.

  • Dimensions of Tandem-Axle Trailer Equalizer
    I went out to the warehouse and pulled part # AP202 and took some measurements of the equalizer for you. From the center of the bolt hole to the center of the bolt hole the equalizer measures exactly 10 inches. The overall length is 11-1/16". These equalizers are designed for use on trailers with tandem, 3,500-lb to 8,000-lb axles. I have included a picture showing the measurements for you to check out.

  • Tandem Axle Version of Triple-Axle Trailer Equalizer Kit for 2" Slipper Springs AP302

  • Are Components of Slipper Spring Equalizer Kits AP302 and AP202 the Same
    The individual components between the two kits are the same but the quantities are different since the part # AP302 was designed for triple axle trailers and the # AP202 is designed for tandem axle trailers.

  • Suspension Kit Needed for Slipper Springs, Tandem Axle Trailer
    We offer several suspension kits for tandem axle slipper springs. The # AP202-H202 kit that you referenced is designed for slipper springs and tandem axles.

  • Hangers Needed For Slipper Springs
    First, you will want to make sure you choose hangers that are designed for slipper springs. The width of the hanger should match the width of the leaf spring. You could use the existing bolts, but hangers use different diameter bolts. It will be important to make sure the bolts you plan on using will fit in the hangers and springs. In addition to the 4 shackle bolts, you will also need 2 equalizer bolts and at least 4 spring keeper bolts. Using a kit is the easiest way to make sure...

  • Do Suspension Hangers Need to Welded on Or Can They be Bolted On
    You will want to weld the hangers of the Trailer Hanger Kit # AP202-H238. The holes you see are not designed to have bolts run through them. If you did run bolts they would most likely interfere with the spring and how it would sit on the hanger. I would recommend you have a qualified welder do this for you. They would easily be able to move them again if needed.

  • 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,...

  • Spring Spring Hanger Spacing for Spring SP-161275
    The B dimension on a slipper spring is the distance that should be between the hanger and the mounting point on a slipper spring equalizer. For example the part # SP-161275 that you referenced should have a distance of 24-7/8 inches between the first hanger and the equalizer mounting point. Since equalizers can have different lengths there isn't a standard dimension with this spring. Let's use hanger kit part # AP202-H238 as an example. The first hanger of the hanger kit part # AP202-H238...

  • Spring Hanger Spacing Dimensions for a Tandem Axle Slipper Spring Suspension on a 14,0000 lb Trailer
    The hanger spacing for a tandem axle trailer suspension setup can be determined, but you need to take into account the axle spacing needed for the overall diameter of your wheel and tire combination and the springs you will be using. Lets say that you plan on using 4 of the 5-Leaf Slipper Springs, # SP-232275, for 7,000-lb Trailer Axles, and that your wheel and tire combinations are the Karrier ST235/85R16 Wheel and Tire, # AM32764. The AM32764 wheel and tires overall diameter is 31.61...
