• Dimensions of the Roadmaster Comfort Ride Slipper Spring System
  
• I went out to our warehouse and measured one of the Roadmaster Comfort Ride Slipper Spring System like part # RM-2460-2570 for you. The box is 3-1/4" wide and the opening is 3-3/4" long x 2-3/4" wide. I have attached a photo of these measurements for you as well. According to my contact at Roadmaster, the center leaf spring hanger will need to be between 3" - 3-1/2" from the bottom of the frame to the center of the bolt hole. If the hanger you have will not work with these measurements...

• Trailer Suspension Hangers for Dexter Heavy Duty Suspension Kit # K71-360-00
  
• There are different hangers that you could use with the Dexter heavy duty suspension kit # K71-360-00. To achieve 4-1/2 to 5 inches clearance between the trailer frame and axles you could use 6 of hanger # 28-5. To achieve 3-1/2 to 3-1/4 inches clearance you could use 4 of front/rear hangers # 115917 and 2 of center hanger # 115918 but these are usually found on lower capacity axles. These are going to be the most common set ups and should work well for you.

• Can Mor/Ryde LRE Suspension Hangers Be Replaced by Dexter EZ-Flex
  
• To replace your current Mor Ryde LRE system and go with an EZ-Flex system is possible, but you will need to replace the center hangers as well as the equalizers to do this. To pick out the correct equalizer will require you to measure the distance between the bolt holes from left to right on your current setup so that you can get the correct EZ Flex. If the distance is between 7-1/4 and 8-1/4 inches the part # K71-653-00 would be the correct equalizer. If the distance is between...

• What Happens if I Change the Size of Equalizers on 5th Wheel Camping Trailer
  
• When changing the size of the equalizer that is on a trailer, this will affect the size of hangers needed or the spacing of the hangers. For example, if you were to go with an equalizer that is one inch taller, you could keep the center hanger the same but would need one inch longer end hangers. If you replace your current equalizer with one that is longer, you would have two options. One would be to find shorter springs but the easier option would be to move the spring hangers further...

• Can Trailer be Raised by Installing Longer Hangers
  
• Replacing your trailer's hangers with longer ones will raise it. Using # 28-5, which are 3-1/4 inch hangers, will likely give you the clearance you're looking for. Another option is an over-under kit. This moves the leaf springs over the axle lifting the trailer. It's often referred to as "flipping the axle' although this isn't the acutal process since trailer axles are bowed and cannot be install upside down. We carry two over-under kits depending on your axle size, part # K71-385-00...

• What Would Cause a Trailer Equalizer to Flip Up to One Side
  
• Can you please send me a photo of your equalizer and how it is positioned on the axle? As long as the shackle straps are facing the correct direction (see photo) and the equalizer is not contacting the trailer frame then I don't see an issue. The weight on the trailer could be moreover one axle than the other which would cause the equalizer to flip up or the leaf springs could be a slightly different length. Unfortunately, measuring a trailer leaf spring is not exactly cut and dry. The...

• Will Frame Support the More Centralized Pressure of the Timbren Silent Ride Suspension System?
  
• The Timbren Silent Ride Suspension for Tandem Axle Trailers w/ 2-1/2" Round Axles - 7,000 lbs # TSR7000T06 will actually give you more frame contact than a typical leaf spring system as the hangers like # 28-5 have less contact, but you are correct it will be more centralized. The frame can absolutely handle the weight over the 11-1/2 inch mounting plate. Another thing to note is the pivoting arm that will disperse weight as it comes in contact with the frame when necessary for stabilization....

• Single Axle Trailer, Should the Hanger or Shackle Be on the Front of the Trailer Frame
  
• It sounds like you have a single axle trailer and are curious about whether or not to put the hanger like the part # 28-5 or a shackle in front on the trailer frame. We recommend you put the hanger in the front. The force from the bumps in the road not only pushes up on the suspension but it also pushes the axle to the rear of the trailer. Having the shackle in the rear allows that rearward shock get absorbed better as it allow for slight movement rearward.

• Proper Position of Equalizer and Shackles on Trailer Suspension
  
• I attached a picture that shows the proper position of shackles and equalizers on trailer suspension. Sometimes the shackle will flip up but if you jack up the trailer by the axle that's got the shackle flipped you can usually get it to flip back over.

• Do Hangers Have a Specific Width They Should Be
  
• Although I wouldn't be able to give you the specs for what should be on a Grand Design (that's something only the manufacturer can tell you) I can tell you hangers which fit 1-3/4" leaf springs have an inner width that is close to 1-3/4" such as # 115917 which has a 1-13/16" inner width. There is not an adapter kit but if you are uncomfortable with the hanger and particularly the weld you can replace them with a new Hanger Kit such as # APT5 which uses 3-3/4"" tall hangers with 3" long...

• Trailer Suspension Equalizer Tilted Up At one End
  
• The suspension in general on your trailer looks very worn. I would replace as much as I could on it to get it back to good working order. The problem with the equalizer cocked to one side like that can happen sometimes. It usually fixes itself when a load is put on the trailer. What I recommend though is to jack up the trailer and use a pry bar to get the leaf spring end up above the equalizer so the equalizer is straight and then let the trailer back down. Regarding the tires being...

• Will Using Longer Suspension Hangers Make a Trailer Ride Higher
  
• The hanger length can affect the trailer height. You would need to change the height of all the hangers equally to keep the geometry of the trailer the same. But at the end of the day there are other ways to get more height on a trailer. Keep in mind that increasing trailer height changes the center of gravity on the trailer and can also change the tongue weight and lead to sway problems. If the springs on your trailer are currently mounted under the axle, you can use an over-under conversion...

• Solution for Raising Trailer to Prevent Lippert Ground Control From Dragging in Driveway Transition
  
• Normally when there's dragging we recommend using a skid wheel to prevent the contact. But for a jack leg that won't work. Is there anyway to approach the driveway at a better angle so that dragging won't occur? Otherwise you'd have to look into raising the trailer. 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...

• Angle Of Shackles On Trailer Appear Wrong When Installing Leaf Springs
  
• Ff the springs you are installing are 25-1/4 inches, you would need to place the hangers between 24-3/4 and 25 inches apart. The shackle should be angled as the drawing shows in the attached helpful article, which should be toward the rear of the trailer. Make sure the trailer is not under load when you are installing the hangers and it never hurts to double check the measurements of the springs and the hanger locations as well.

• Raising the Height of a Tandem Axle Keystone Springdale Clearwater Trailer
  
• Using an over-under conversion kit such as # K71-384-00 or # K71-385-00 raises the height of a trailer which also raises its center of gravity. This makes the trailer more susceptible to sway but doesn't necessarily mean that sway will happen just from raising the trailer height. Its just a possibility. This is a job someone could do at one. But the new spring seats should be tack-welded in place which does require the proper welding equipment. You should not have to worry about realigning...

• Suspension Setup Recommendation for a Camper Trailer that Will be Taken Offroad
  
• Leaf springs aren't any more designed for off-road use than slipper springs. What I would recommend is a Timbren axle-less system as they offer the best ground clearance since they do not have an axle that runs across the trailer. I attached a page that has all of the Timbren systems we offer for you to check out. You will want to pick out the system with enough capacity for the weight of your trailer and the same bolt pattern as your trailer wheels. For even more ground clearance some...

• How to Gain Ground Clearance for a Travel Trailer that Hits the Driveway When Entering or Leaving
  
• There are a couple different ways to raise the ride height of your trailer, but before we choose the best option for you, we will want to take a look at a few things. First, it sounds like you are not towing with your trailer level so you do not hit your ball mount on the driveway. A trailer that is not level can create many problems such as ground clearance and trailer sway. If you have any sway control issues with your trailer, then I would recommend moving your leaf springs above...

• 3,500 lb Leaf Spring and Hanger Kit Recommendation for Homemade Trailer
  
• You have a pretty interesting leaf springs setup on your trailer. It appears as if it is an automobile spring setup based on the length of the springs. That is a pretty small trailer, are you sure you want to go with such heavily rates springs? Going with higher rated springs will only give you additional spring capacity. If the axles or frame of the trailer aren't rated that high you don't effectively increase the capacity of the trailer. For a 3,500 lb spring the part # SP-212275...

• Can a Trailer with Axles Over Leaf Springs Be Lifted
  
• If your axles are already above the leaf springs the only way to increase the height of the trailer is to install taller hangers. You should note that this route isn't going to give you a dramatic lift. The biggest issue your setup has is the tall rims and tires on your trailer. Normally trucks with lifts or large wheels can't tow fifth wheel trailers easily. If you are within a couple inches of being able to tow your trailer level without overhang/bed rail interference you could...

• Will Increasing Spring Shackle Length Allow More Clearance Between Tires and Fenders
  
• Because a suspension is not static but is meant to articulate, going with longer shackle links won't provide the clearance you're looking for. The best course of action would be to raise the fenders to provide the proper clearance. At the very least, you want to see at least 3 inches of clearance between the tire and the underside of the fender with the suspension at full load. A better bet for gaining height would be to go with taller spring hangers. Keep in mind that the amount by...

You will then need to select from the filters which size you need.

• Recommendation for Increasing Axle to Trailer Frame Clearance
  
• Actually, what will solve your axle-to-frame clearance issue you are having the easiest would be to move the axles from being above the leaf springs to below the leaf springs. That will give you a great deal more clearance between the frame and the axle and won't require you to change anything about your current leaf spring hanger setup. 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...

• How to Raise a Trailer for More Ground Clearance
  
• There are a couple of things that you can do to get more ground clearance for your new trailer. First, if the leaf spring stack is attached under the axle then you could use an over/under conversion kit. If the trailer has a 2-3/8 inch diameter round axle use # K71-384-00. If it has a 3 inch diameter round axle use # K71-385-00. This will move the leaf spring stack to the top of the axle and raise the trailer approximately the same amount as the axle diameter. These kits will only...
