• Are Side-Frame Mount Jacks Available With Different Gear Ratios
  For that I recommend an electric jack set like the Ultra-Fab Deluxe Electric Landing Gear Set # UF17-943010 which has a combined 12,000 lbs of capacity, and offers 38" of lift.

• Recommendation for Adding Third Axle To Trailer Suspension
  The Dexter Heavy Duty Suspension Kit # K71-360-00 is designed for 33 inch axle spacing. To add your third axle, you cannot simply add a hanger spring and axle. You can keep your 35 inch spacing but you will need to relocate your hangers. I've attached an article to help with the proper positioning of your axles. You will need to add another equalizer of the same dimension as you have to each side and then add the same leaf springs and shackle straps as what you currently have. You...

• Suspension Recommendations for a Triple Axle Gooseneck Trailer
  We do have a variety of spring hangers you can use for a 7K triple axle system, and or that I recommend the Triple-Axle Trailer Hanger Kit # APTT5 which will space your axles 34" apart on center (see attached photo) and is compatible with 1-3/4" wide leaf springs like the 7K 6-Leaf Double-Eye Spring # e64SR. You'll need to have your current hangers cut off and this new kit welded on for the installation. You can use your current axles but I will say that mobile home axles are only designed...

• 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. For the axle itself, let...

• What Leaf Springs, U-Bolt Kit, Equalizers, and Wet Bolt Kit do I Need for My Triple Axle Set-Up?
  Hello Mike, Thank you so much for the detailed information, most helpful! For the leaf springs, you will want to go with (6) of the 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles - 24-7/8" Long # e64SR. Since you have 7K axles, these are the correct match, as each spring is rated for 3,500 lbs. That pairing is exactly what you want for proper suspension performance. While it might seem like stepping up to a 4,000 lb spring would be an upgrade, it actually makes the suspension too...

• Is There A Galvanized Triple Axle Hanger Kit?
  Hey Joe, The triple axle kit # APTT5 is not a galvanized steel kit, it is going to be powder coated. I took a look through the different kits we have and I did not see a hanger kit that is galvanized. We do have leaf springs that are galvanized themselves but in terms of a full triple axle kit we do not have one that has galvanized pieces. What king of trailer are you wanting to do the work on?

• Correct Hanger Spacing for Triple Axle Trailer with 26-1/2" Double Eye Springs
  Thanks for reaching out, Eric! According to my research it looks like you're needing to space the outer hangers 29-1/2" apart and the inner hangers 33" apart since you have 26" long leaf springs. If you check out the linked photo we have for the Triple-Axle Trailer Hanger Kit for Double-Eye Springs # APTT5 the "A" and "C" measurements will need to be 29-1/2" while the "B" measurement would need to be that 33".

• How To Determine Hanger Spacing For Triple Axle Boat Trailer With 27" Leaf Springs
  Hello John, thanks for reaching out. I an provide some rough guidelines for you, but there is not a "set in stone" hanger spacing for a 27" leaf spring and I cannot provide exact locations for anyone spring and hanger combo unfortunately. 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.

• Parts Needed To Convert Triple Axle Boat Trailer From Hydraulic To Electric Brakes
  Hello Edward, I can definitely point you in the right direction. Generally, we do recommend using hydraulic brakes for a boat trailer, since electricity and water do not mix well. If you want to add electric brakes, you will need electric trailer brake assemblies, hub/drum assemblies, a 7-way trailer wiring harness, an emergency breakaway kit, and an electric trailer brake controller for your vehicle. In order to recommend the correct parts, I will need more information on your trailer....

• Recommended Lift Kit for a Triple Axle Trailer
  No, I am sorry we do not sell the MORryde Suspension Upgrade Kit for Triple Axle Trailers item # MR86ZR with the hangers from the Triple-Axle Trailer Hanger Kit item # APTT5. I checked with MORryde and they don't offer kits like that either. You can buy the hangers separately with item # 28-5 but it wouldn't be cost effective plus you would still need equalizers. Another option other than replacing your hangers is to use the Correct Track Trailer Alignment and Lift Kit item # RR55QX....

• Recommended Hanger Spacing for Triple Axle Trailer
  There will be different dimensions between the hangers. From front to back your hangers for that 20-3/8 inch spring like # e84SR will be 24-3/4 on center then 29 inches on center and finally 24-3/4 inches on center. This will put each of the 3 axles 28-1/2 inches on center. I've attached a photo to assist. This is all based on 7-3/4 inch curved equalizers and 2-5/8 inch long shackle straps. These are found in the Triple-Axle Trailer Hanger Kit for Double-Eye Springs - 3-1/4" Front/Rear/Center...

• 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...

• 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...

• 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...

• Parts Needed To Convert Tandem Axle Trailer To Triple Axle
  I would be happy to help! 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. Moving on to U-Bolts you will need 3 of the U-Bolt Kit...

• 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...

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.

• 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...

• Troubleshooting Front Equalizer On Triple Axle Trailer Hitting Trailer Frame
  Based on the picture you provided you will need to replace the center hangers on your triple axle trailer with the Center Hanger for Double-Eye Springs - 5-7/16" Tall - 3/4" Bolt Hole # 115919 which is just under 2-1/4" taller than the center hangers included in the # APTT5 you purchased and will give you the additional clearance you need. I included a video of the # 115919 for you to take a look at.

• 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.
