• How to Determine Correct Replacement Leaf Springs for 7,000 lb Axle
  I can give you some guidance on how to determine the correct replacement leaf springs, and you are right that replacing all four of them at the same time is a good idea. What you'll need to do for double-eye springs (which is what I assume is on your 2017 Keystone Fuzion) is measure from the center of one eye to the center of the other eye and get a match as close as you can. Just take into account that the springs may have elongated a bit over time. For example, the only double eye...

• Leaf Springs for 8K-Rated Axle
  We do offer both double-eye and slipper-type leaf springs for many axle weight ratings. You can see all of these leaf springs on the page I linked for you.

Both are 2-inches wide. Please note that leaf springs tend to stretch when they are worn so the length of the old spring you remove...

• How to Determine Correct Replacement Springs for a 2019 Keystone Fuzion 424 Toy Hauler with 7K Axles
  I was able to find that your 2019 Keystone Fuzion 424 Toy Hauler has 7K axles and while we do have leaf springs for 7K axles, you'll need to take some measurements of your leaf springs to ensure that you get leaf springs that are the correct length for your application. Height can be a factor as well unless you are swapping out all of your leaf springs on all of your axles. If you are referring to suspension enhancement we have that too. Unfortunately we don't have a way to look up exactly...

• Replacement for Dexter Part Numbers 072-098-00, 011-017-01, and K23-464-00/K23-465-00
  Absolutely, the Dexter leaf spring part 072-098-00 is a double eye spring, designed for 7,000 lb axles, with a 25-1/4" eye to eye measurement. The closest leaf spring we have to that is the Double-Eye Spring part # SP-198275 which is a double eye spring, designed for 7,000 lb axles, with a 24-7/8" eye to eye measurement. The 3/8" difference between the eye to eye measurements will not cause an issue. The Dexter u-bolt part 011-017-01 is a 1/2" diameter bolt, designed for 3" diameter...

• Could Replacing Older Trailer Leaf Springs Gain Additional Height to Trailer
  Most likely your springs are sagging a bit if they are over 10 years old. Since it's a good idea to replace those anyway that's probably a good place to start. In the 7,000 lb capacity we only have one size of 24-7/8 inches as part number # SP-198275. Even going with a new set of 6k springs will be an upgrade. For that we have a few lengths like part # SP-111275 which is 25-1/4 inches long, # SP-053275 which is 26 inches long, or part # SP-221275 which is 25-1/8 inches long.

• Warranty Length and Improvements that Lippert Center Point System Offers to Trailer Installed On
  The Lippert Components Center Point by Trailair Air-Ride Suspension Upgrade # LC1565391 that you bought has a 90 day warranty. This system has only one inflation point which equalizes the pressure between both sides of the trailer so it does not have a way to have more pressure in one side than the other. This system is designed to greatly improve the suspension performance and ride quality of the trailer you install it on but does not necessarily provide additional support although it...

• Leaf Spring Upgrade and Over Under Conversion Kit For Montana Trailer
  When replacing the leaf springs you do want to take into consideration that the leaf springs sag and flatten over time. The best way to measure them is when the suspension is not loaded. To measure for the correct leaf spring length, you should jack up the trailer so that the axle hangs free, then measure straight across from the center of one eye to the center of the other eye. See what your measurement is then to choose the correct length of spring. It is okay to use a higher rated...

  In order to make sure you get the correct replacement parts you will want to take a measurement or two.

You need the eye-to-eye measurement to make sure you get the right length spring for your trailer. It is recommended that new leaf springs should be installed on both sides of the trailer to make sure the suspension is equal and performs well. The leaf double-eye leaf springs...

• Replacement Double Eye Springs for Double Axle Toy Hauler
  We have double eye springs you may be able to use as replacements, but none that are rated for 8,000 lbs. If your 7,000 lbs springs are worn out, you would need to measure from the center of your spring eye to the center of the other spring eye. If that is roughly 24-7/8" (some stretching should be accounted for), there is the 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles # SP-198275. I've added a link to a video review of this spring for you to take a look at as well.

• Can a 7k Rated Leaf Spring be Used on a 6k Rated Trailer Axle
  A 7,000 lb trailer spring can be used on a 6k rated axle but you should note that this will not give you more capacity. A trailer setup is only rated as high as it's weakest component. So while you may have 7k of spring rating with the # SP-198275, you would still only have 6k of axle rating.

• Can I Use Heavier Rated Leaf Springs on Trailer Without Causing Damage
  You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part # SP-198275 measures 24-7/8" eye to eye. The only thing you may notice is that the ride may be a bit stiffer with the heavier rated springs. Please keep in mind upgrading to a 8,000 lb spring may require you to switch over to slipper springs instead of double eye springs. Which...

  The Universal Group 6-Leaf Double-Eye Spring # SP-198275 referenced in your question is designed for 7,000 pound axles like what you have on your trailer.

• 6k Leaf Spring for a Forest River Toy Hauler
  Are you sure you aren't exceeding the capacity of your trailer? Going with higher rated springs will give you additional spring capacity but will not increase the overall capacity of your trailer. The only way going with new leaf springs like part # SP-198275 will fix the sag is if your current 6k springs are worn out. These measure 24-7/8 inches. You would need to unweight your current axle and measure the length. If your current springs are around 25-1/4 inches long these would...

• Replacement Leaf Spring Recommendation for Trailer with 25-1/8 inch Springs and 2k Capacity
  Most likely the measurement is 25-1/8 inch as that is a common size. But in most cases we recommend measuring the spring with it off the trailer and typically there is a bit of stretch to old springs by around 1/2 inch or so. The spring you would want is the part # SP-219275 as it matches the capacity needed closely and it has a length of 25-1/8 inches like you have. When picking out leaf springs priority one is picking out the correct capacity and then finding a spring that is close...

The axle spacing will be 33 inches which is pretty close to the dimension you listed but short by 3-3/4 inches.

• How to Determine Correct Replacement Leaf Spring for 2004 Forest River Toy Hauler Trailer
  Trailer leaf springs will measure differently when under load so its tough to get an accurate eye-to-eye dimension without removing the spring. Also, after years of use a leaf spring can stretch and actually lengthen by as much as 1/2 to 3/4-inch. Since you are seeing some sag and the trailer is a decade old that is likely to be the case unless there is another suspension component that is damaged. I checked the Forest River website for any information on your toy hauler's suspension...

• Recommended Clearance Between Tire and Trailer Frame Rail
  The minimum distance between the inside of a tire and the frame rail depends a lot on the setup of the trailer. But as long as the tire and the frame don't touch you would be fine. It's hard to give an exact figure as trailer setups can vary and some trailers may have more side to side movement which would call for more clearance. If the suspension is good on the trailer and not worn out I would go with at least 1-1/2 inches to be on the safe side. Some might get by with 1 inch but...

• 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 # SP-169275 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"...

This measurement is from center to center of the hangers. Check out the pictures I attached that show

• Typical Hanger Spacings for Tandem Axle Trailer with 3,500 lb Axles
  A lot of it depends on the length of the springs and equalizers that are used. When using Leaf Springs # SP-198275 with the # AP233 Equalizer Kit and the # H248 Hanger Kit, there should be 29-1/2" between the front and center hangers and 29-1/2" between the center and rear hangers. This should achieve a 4-1/2" clearance between the center of the axle and the trailer frame if you have a 3500 lb axle. I've Provided a diagram that should be helpful. I've also provided a link to our trailer...

• How to Measure Spring Length and Determine the Correct Replacement Springs for a Trailer
  Measuring the distance from the center of one eye on your original springs to the center of the other eye will give you a general idea of the length of the new springs you need. Your springs may measure slightly longer due to wear so you will want to select a spring that is slightly shorter and matches the capacity of your trailer axle. Adding springs to your trailer that have a higher capacity than the axle capacity or the capacity of the hub and drum components is not recommended....

  What you have is a little long however still may work. It's hard to give you exact numbers sice we don't currently carry any 27-1/4 inch springs.

All measurments are center on center. Your numbers are fairly close but if they are too long it will decrease the amount of travel in the trailer's...

• How To Find Replacement Slipper Leaf Springs For Older Enclosed Trailer
  The best way to find replacement springs for your trailer is to know the capacity of the axles on your trailer. The axle may have a plate that has the capacity on it. If you are not able to find that information you may be able to tell the capacity by the size of the axle. For a 1000-2000 lb axle the diameter is typically 1-1/2 to 1-3/4 inches. A 3500 lb axle are usually 2-3/8 inches diameter and 6000 to 7200 lb axles are 3 inches diameter. An 8000-lb axle will be 3-1/2 inches diameter....
