We installed the kit on a home-built 25' gooseneck trailer that we were converting from 2 axles to 3. This kit, along with new leaf springs on all 3 axles, went on with no issues, and it has been running strong with no problems since the installation. We've put quite a bit of weight on the trailer between logs, lumber, tractors, and equipment, and there have been no issues so far. It was great to have everything we needed, (other than springs), in one kit!

And etrailer has always been good about fast delivery, easy purchasing, and great updates on status. Things have gone so smoothly that we have never had to contact Customer Service, so I can't comment on how they do!



by:

I ordered this kit for a trailer that I bought as scrap iron to haul logs so I wouldn't tear up my good trailer. The first load I broke 3 shackles and 2 equalizers. I looked at parts and found this kit at a great price to rebuild my suspension. I had it within 3 days of the time I ordered, And the service was great!! The best part....... when I got the box I thought they knew me personally and had already seen the trailer I was working on, Redneck Trailer Parts LOL. I plan on getting rid of the redneck dually setup with a different set of axles and get rid of the trailer house wheels and make it into a gooseneck. I will for sure get all my parts from Etrailer.com for the rest of this project and any other trailer parts I need. VERY VERY pleased with the parts, service and fast shipping!!



by:

Robert p was give little info on what I needed. I was sent the items and they were perfect fit.. I’ve been using Etrailer for probably 15 yrs and never disappointed with product and customer service..



by:

I purchased this kit to replace my existing suspension on an old equipment trailer. Very happy with the product and the help that I received from Londyn in taking the time to help me find the right set to fit my trailer requirements.

A tip for if you are replacing them on a trailer with existing shackles or if you don't want to pull the axles out from underneath the trailer. If you set up the hangers onto a 2x4 you can clamp them into place with the board holding them in place and inline with each other so you can tack weld them to the frame without worrying about them bowing or twisting out of alignment. And it will save you lots of time and frustration.



by:

The bushings in my equalizers were worn out, so I was just going to buy new equalizers, then I decided to buy new bolts also. This kit cost less than the equalizers and bolts so I bought it. I went ahead and used the new shackles, but I now have a set of hangers laying around. It all fit well. I used it with PR4 springs. My existing hangers were already set up with the dimensions shown on the web page for this kit.



by:

The bolts and shackle set that I bought worked out wonderful bolted right up no issues had it done in a couple hours thanks so much Etrailer.com

Very good



by:

A couple bolts and nuts lost due to shipping damage. One call to etrailer and the missing items were on the way. Great service



by:

We had an old tri-axle that needed work. Overall a good trailer just many road miles and worn parts. With this kit we were able to get it on the road again, with parts that match the job went quickly. The website even offered a diagram for proper spacing of the hangers for the layout.
This is only the second time I have used E-trailer, but if they keep up the great service, I can see many years of business helpiong to maintain my fleet of 100+ vehicals.



by:

Great quality. Great price. Went on 22k tri axle gooseneck. Tightened everything right up. Only wish is that the nylon bushings were softer steel aloy for longevity sake.



by:

Excellent quality. Needed a full triple axle kit. Everything was there. Turned the trailer over and had it put together and welded up in about 4 hrs. Will definitely be ordering more product from this company in the future.



by:

Everything is great all finished I appreciate the great service I’ve received from etrailer over many years



by:

Great products and service!! All parts were correct, delivered fast and fit like a glove. Thanks You etrailer.com



by:

Perfect for the dump trailer I am building. Product was shipped fast and in good condition when it arrived. The product is easy to install but it would be nice if they added mounting instructions with the parts. This information is available on their website however and is easy to follow



by:

My order was on hold fore quite some time so I called and spoke with Lauren and she took good care and found their was only one item holding things up so we canceled that item and she got the remaining order shipped right away. Ask for Lauren if you want it done right!

Worked as described. Got my trailer pulling like new.

  • Leaf Springs and Shackle Straps for Triple Axle Trailer with 7-3/4 Inch Equalizers
    The issue you are experiencing is a result of leaf springs that are too long for your hanger spacing. You will want shorter springs and I recommend also going with a capacity more geared toward your axles. You will want to use the Triple-Axle Trailer Hanger Kit for Double-Eye Springs # APTT5 and # APTT3 for reference. These kits are rated for 2,000 to 7,000 lb axles with almost identical spacing. My recommendation for you is the 6-Leaf Double-Eye Spring for 5,300-lb Trailer Axles...

  • Do The Trailer Suspension Hangers & Equalizers Need To Be Changed Going From 3,500 to 6,000LB Axles?
    You may be able to use the same hangers and equalizers that are already being used on your triple axle trailer. First you will need to determine if you will be changing wheel and tire sizes that will require you to move the axles further apart so that the tires do not contact each other. This may also affect your trailer fenders if the axles are being spread further. If your tire spacing is okay you will then only need to find the larger capacity leaf springs that match the length of...

  • Does Trailer Suspension 7-3/4 Inch Equalizer EQ-E1 Have a Weight Capacity
    Equalizer # TREQE1 does not have a weight capacity itself. It isn't bearing much of the weight compared to other components in a trailer suspension set up. If you have a tandem axle trailer then you could potentially use kit # APT5, # APT3, # APT9, # APT8, # APT7, or # APT3HD. All of these kits have the 7-3/4 inch long equalizers. For a triple axle trailer you could use # APTT5 or # APTT3. All of the above kits also come with hangers. If you do not need hangers then you would need to...

  • Recommended Triple Axle Setup for Tiny Home Trailer
    The best trailer axle option we have for your custom tiny home trailer build is going to be the Dexter Trailer Axle w/ Electric Brakes part # 8327864-EB for 7,000 lbs. This axle is top of the line and comes with everything you need for bolt-on installation. It comes with electric brakes, 8 on 6-1/2" hubs, and zerk fittings on the axle for easy maintenance. The hub face to hub face measurement is 94" so once you have wheels and tires on you will be around 8-1/2' wide. I have attached some...

  • Triple Axle Boat Trailer Suspension Clearance Problems After Installing New Front Springs
    The first thing I would check on is the capacity of the new springs that you had installed on the trailer. You need to be sure that the spring capacity is rated at 1/2 the axle capacity. That way 2 springs equal the capacity of the trailer axle for proper fit. Check the arch of the springs with a level top of spring to top of spring to tie bolt. Next, check the suspension components on the trailer and make sure there is no damage. The Spring hangers, equalizers or shackle straps could...

    I do have a guideline for you in regards to trailer leaf spring hanger spacing on a triple axle trailer with 25-1/8" to 25-1/4" trailer leaf springs but we can't offer specific measurements as there are too many variables involved.

  • Correct Hanger Spacing Using Triple-Axle Hanger Kit With 3,500 Lb 25-1/8 Inch Long Leaf Springs
    The correct hanger spacer when using the Triple-Axle Trailer Hanger Kit part # APTT5 with the 4-Leaf Double-Eye Spring part # e54SR is 29-1/2" from the front hanger to the center hanger, 34" between the center hangers, and 29-1/2" from the second center hanger to the rear hanger. Please note, you will also need the U-Bolt Kit for Mounting Kit part # APUBR-1 in order to mount the leaf springs to the axle.

  • Reasons for Different Spacing Between Hangers in Triple Axle Hanger Kit
    The difference in the spacing for the # APTT5 hanger kit comes in to play with the center spring due to the additional components attached at each end of the spring. Both the first spring and last spring have the same spacing since they are each attached to the hanger at one end and the equalizer at the other. The center spring however is attached to two equalizers. Since the center spring doesn't contact a hanger directly, some additional space is needed between the hangers to accommodate...

  • When Converting from Tandem Axle to Triple Axle Where Does Third Axle Install
    When going from a tandem axle trailer to a triple axle trailer you want to install the center axle where the current center hanger is for your tandem setup. This means you have to remove both of your current axles to position them properly. This gives you the additional axle support you want without throwing off how much tongue weight you have relative to the trailer weigh. We have triple axle hanger kits like the part # APTT5 you could use too. You should note that you will be increasing...

  • Triple Axle 5th Wheel Trailer Has Center Axle Forward and Backward Movement
    Some movement is normal. This is because there are two pivot points, one at the second hanger and one at the third hanger which are on either side of the center axle. What you will want to do is check several things to determine if there is wear that is causing excessive movement. Check the shackle straps, equalizers, and hangers to see if the holes have elongated. If so they will need to be replaced. Also make sure the u-bolts are tight and in the correct position and that the nub on...

  • Differences Between Triple Axle Hanger Kits APTT1, APTT3, and APTT5
    The differences are the dimensions of the hangers and equalizers of the three kits. The # APTT1 uses totally straight equalizers and taller center hangers. The # APTT3 uses more traditional sized equalizers and center and outside hangers that differ in size slightly. The part # APTT5 uses a standard sized equalizer and hangers that are all the same height. The part # APTT3 is the one that is the most commonly used. It would be my recommendation for your trailer.

  • Leaf Spring, U-Bolt Kit, and Hanger Kit Recommendation for Triple Axle Trailer
    For 7,000 lb axles we have the leaf springs part # SP198275 which is a great starting point. You'd need a total of 6 of these. Then for a U-bolt mounting kit for 7k axles we have the part # APUBR-8 which you'd need three of. Then for a triple axle hanger kit you'd need the part # APTT5 and you'd be set.

This kit includes 3-1/4" hangers measured from the frame to the center of the mounting hole. If you have a different height hanger please let me know and I will find you the correct height hangers.

  • What's Involved to Add a Third Axle to Trailer Suspension
    The first thing you'll need is to determine what the correct axle is that you need. To do that you'd need to know the capacity of the axle, the distance between spring seats, and distance between hub faces. With that info we can see if we carry the axle you'd need or if you'd need to custom order one locally. Next you need to consider that all of the current suspension hangers will need to be moved. Unfortunately you don't get to just add a third axle in front of or behind your current...

  • Distances Between Hangers for Triple Axle Kit when Used with Hanger Kit APTT5
    Yes we do have a chart that shows how to space the axles of a triple axle trailer with a hanger kit like the # APTT5 that you referenced. I attached this chart for you to check out as well. The bottom section of the chart is for use with springs that are 25-1/4 inches in length from spring eye to spring eye. This is most likely what you have. The upper portion is for springs that are 20-3/8 inches.

  • Parts Needed to Convert a Tandem Axle Trailer to a Triple Axle Trailer
    Daniel, you can add a third axle but you're going to want to keep all of your axles the same size. So if you wanted 6K axles instead of 5.2K then you'd want to swap the other two as well. With that said, to add your third axle you're going to need the U-Bolt Kit for Mounting 5,200-lb to 7,000-lb, Round Trailer Axles # APUBR-8, the Triple-Axle Trailer Hanger Kit for Double-Eye Springs # APTT5, and the 6-Leaf Double-Eye Spring for 5,300-lb Trailer Axles # e76SR.

To add a 3rd axle you will need to start with a new hanger kit of which I recommend the Triple-Axle Trailer Hanger Kit for Double-Eye Springs - 3-1/4" Front/Rear/Center # APTT5. This will work perfectly with the Lippert 7k axles you have. Next you will need 6 of the 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles - 24-7/8" Long # e64SR which when paired with the # APTT5 will give you 34" axle spacing.

    You shouldn't need to modify the hangers at all on your trailer when going from a straight equalizer like # TREQR2 to Y-shape units like the ones in the Triple Axle Kit # APTT5 that you were looking at. The shackle strap angle will make up for the difference between the two designs. The difference in height between the front/rear hangers and the middle hangers on your triple axle trailer is not uncommon. This is actually the more standard method than using hangers of all the same length....
