• Recommended 7-3/4 Inch Suspension Equalizer with 3/4 Inch Center and 9/16 Inch Bottom
  The Tandem-Axle Trailer Hanger Kit for Double Eye Springs - 3-3/4" Tall Front/Center/Rear # APT5 has the wider 7-3/4 inch equalizers you referenced but all holes are 9/16 inches (top and bottom).

• How Much Space Should be Between the Top of the Axles and the Bottom of a Boat Trailer
  Normally when using hanger kit # AP233-H248 with spring # e66SR the distance from the bottom of the frame to the center of the axles is going to be approximately 4-1/2 inches. Subtract half the width of the frame then to the top of the axles that would be 3-5/16 inches. Two inches might work out fine depending on how far the suspension travels but more height would likely be needed considering the heavier load. Hanger kit # APT4 would provide more height since it has taller hangers than...

• Recommended Hanger Spacing for 24-7/8 Inch Long Leaf Spring with APT4 or APT3HD Hanger Kit
  Based on my research, when using the Universal Group Leaf Springs # SP-222275 that has a spring eye length of 24-7/8 inches with either the Redline Tandem Axle Hanger Kit # APT4 or # APT3HD, you will want a distance of 29-1/2 inches between the hangers on your trailer. Both hanger kits you referenced include everything needed to attach 4 leaf springs to your trailer frame. I have included a couple short video demonstrations on these kits along with an article on positioning a trailer axle...

• Options to Level a Fifth Wheel Trailer that is Being Towed by a Taller Truck
  The easiest solution would be if you could lower the head of your fifth wheel hitch, or raise the pin box of your trailer. Either of these options should allow your trailer to sit more level. You would want to make sure you have between 4-6 inches from the overhang of your trailer to the bedrails though. Another option you have would be to move your axles to below the leaf springs. This is the most common way to lift a fifth wheel trailer to allow the trailer to be towed level if the hitch...

• Options to Lift a 2003 Keystone Fifth Wheel Trailer
  One option you have would be to move your axles to below the leaf springs. This is the most common way to lift a fifth wheel trailer to allow the trailer to be towed level if the hitch and pin box adjustments are maxed out. The diameter of your trailer axle will determine the size of the parts that you will need to order. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00, would be a great choice and if your axle is 2-3/8 inch diameter...

• How Difficult is it To Change Springs Back to Bottom of Axle
  Sounds like you want to move your springs to the top of the axle and want to know how hard it would be to move them back. All you will have to do is reverse what you did to put them on top of the axles. All you will need is the Dexter Trailer Springs Over-Under Conversion Kit like # K71-385-00, if you have a 3 inch round axle, or # K71-384-00 if you have a 2-3/8 inch round axle.

• Raising the Height of a Travel Trailer that Rides Close to the Ground
  If the leaf spring stack on your travel trailer is currently mounted to the bottom of the axle, there is an over-under conversion kit that you could use to gain a few more inches of height. However, this will change the center of gravity on the trailer and can lead to an increased chance of trailer sway. For 3 inch round axles you could use # K71-385-00. And for 2-3/8 inch round axles use # K71-384-00. You should not have to do any welding to use these kits. You would not want to flip...

• Troubleshooting Rear Tires Wearing on Inside for Dual Axle 5th Wheel Trailer
  Thank you for all of that information. From everything that you described it sounds like you are overloading your rear axle. Even though your axles are rated for 8K each and you only have 12,420 lbs on your axles, if your rear tires are wearing on the inside tread then you have too much weight over the rear axle and you need to adjust cargo around in your 2019 Grand Design 367 BHS Reflection 41. Axles naturally have an arced shape and when they are weighed down correctly they straighten...

• Trailer Lift Recommendation for a Trailer with Axles Over Springs
  Aside from moving the axles below the leaf springs the only other way we recommend you lift a trailer is by installing taller spring hangers on the trailer frame. What you would need to do is measure the dimensions of your current hangers and then compare them to the hangers at the attached link and then go with ones that will give you the amount of lift you need.

• Raising the Height of a 5th Wheel Trailer with 2-3/8 Inch Diameter Axles for More Ground Clearance
  You likely have 2-3/8 inch diameter axles. 2-3/8 and 2-1/2 are separated by just 1/8 of an inch so if measuring with a tape measure or ruler it could easily look like 2-1/2 inches. If you are measuring with calipers though that is a different story but I've never heard of a 2-1/2 inch diameter axle. If you do think raising the trailer in the back is the way to go then you may be able to use an over/under conversion kit if: The trailer leaf spring stack is currently mounted under the axles The...

• Trailer Suspension Kit and 6 Inch Long Equalizers for Tandem Axles and Double Eye Springs
  Suspension kit # APT4 for tandem axles with double eye springs has 6-1/4 inch long equalizers so it is a possible option for you. Kit # AP233-H248 uses 5-3/4 inch long equalizers. But if you have to have equalizer # TREQ310 then the individual parts will have to be pieced together since there isn't a kit with that equalizer. If you go that route then you would also need: 8 of # 18-11GALV 14 of # 166081 1 of # H248 (or other hangers, see link)

• Replacement Suspension Kit For Tandem Axle 1 3/4 Springs With 7-3/4 x 2-7/8 Inch Equalizers
  In order to retain your current suspension geometry, you'll need to use an equalizer of the same length and height as the 7-3/4 x 2-7/8 equalizer you currently have. The Dexter Axle # K71-449-00 offers equalizers that are the same width and height as what you have now. The only difference is that the shackle links are a tiny bit shorter, at 2-1/4 inches versus the 2-1/2 you currently have. This difference is very small and won't be enough to have a negative effect on your suspension geometry. Thanks...

• Trailer Suspension Hanger Kit with the Most Lift for Tire Clearance Under the Trailer Bed
  The # APT4 Tandem-Axle Hanger Kit will provide about 4 inches of clearance from the center of the trailer axle to the bottom of the trailer frame, with no load on the axle. This is assuming that your axle tube is 3 inches diameter. If your axle tube is smaller the height will be sightly less. The curve of the springs you select will have some affect also. I would recommend that you go with the APT5 hanger kit because all of the hangers are the same height and it will make it easier to...

• Options for Raising Suspension of a Horse Trailer
  The most common way to lift a trailer is to move the axles below the leaf springs. The diameter of your trailer axle will determine the size of the parts that you will need to order. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00, would be a great choice and if your axle is 2-3/8 inch diameter you could use the Over-Under Kit, # K71-384-00. These kits can be installed without welding but the manufacturer strongly recommends having...

• Will 5-7/16" Tall Center Hanger for Double-Eye Springs Work with 9/16" Bolt
  Even though the 5-7/16" Tall Center Hanger for Double-Eye Springs # 115919 has a 3/4" diameter bolt hole, this is actually designed to work with 1-3/4" wide double-eye leaf springs that install using 9/16" diameter bolts which I think is what you're getting at, so this should work perfectly for your application! If you check out the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs # APT4 you can see where these same hangers are used in a kit that comes with 9/16" bolts so having that...

• How Can I Get More Ground Clearance if my Axles are Already Converted Under the Springs
  From that point the only option you will have to raise your camper would be to add longer spring hangers. Depending on your setup you can get a couple of inches out of these. Measure yours from the frame to the bolt hole and get longer ones like the Front/Center/Rear Hanger for Double-Eye Springs part # 28-5 that is 3-1/4" tall. The Tandem-Axle Trailer Hanger Kit for Double-Eye Springs Kit part # APT4 is also a great way to achieve this and refresh all of the other suspension components.

• Getting More Ground Clearance on a 2012 Lance 1575 Travel Trailer or Other Trailers
  I have a couple of options that will give you more ground clearance depending on how your 2012 Lance travel trailer is set up. First, if the trailer uses double-eye leaf spring suspension AND the axles are on top of the leaf spring stack, AND if you have a 2-3/8 inch diameter round axle, you can use over/under conversion kit # K71-384-00 to move the leaf spring stack to the tops of the axles. For a 3 inch diameter axle use # K71-385-00. If the trailer does not fit the criteria above then...

• How Much Should Wet Bolts be Tightened Down for Hanger Kit # APT4
  When installing the wet bolts, like what comes with the Hanger Kit # APT4 that you referenced, we recommend tightening them down so that the knurls are no longer visible and then backing them off just a little bit. There is no torque rating for wet bolts and you are correct that if you tighten them down too much then it will "lock up" your suspension some. If you follow the procedure highlighted above you will have them tightened correctly.

• Is It Possible to Move Square Axles Below Leaf Springs
  Based on the picture you submitted that shows a square axle welded to a mount which is then welded to a leaf spring you would need to have someone qualified use a cutting torch to remove the mount from the spring so that you could then use a u-bolt style of mounting kit to attach the spring on top of the axle. To do this you will need to know the dimensions of the axle. We have kits for square axles that range from 1-1/2 inch square axles up to 2 inch axles. Once you determine the size...
