• Replacement 26 Inch Leaf Springs, Shackle Straps, And U-Bolts
  
• To give you the correct leaf springs, I would need to know the capacity of your axle or what your Gross Vehicle Weight Rating (GVWR) is not just the weight of the trailer itself. This is the loaded capacity of the trailer. We have a few options for 26 inch leaf springs: 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 26" Long # SP-051275 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 26" Long # SP-124275 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles - 26" Long...

• 25-1/4 inch Long Trailer Leaf Spring Recommendation for 4,000 lb Axle
  
• I attached a page that has all of the double eye springs we carry that are 25-1/4 inches long from eye to eye. For a spring with the same capacity as the one that you referenced the part # SP-220275 would be what you need.

• Replacement Trailer Leaf Springs for 5200-lb Axle
  
• When a trailer leaf spring is well worn it can become elongated. Springs can flatten out and become as much as a 3/4-inch longer, measured eye to eye, than when they were brand new. So the correct replacement spring for your suspension might measure shorter than the worn spring you removed. That said, we do have several 26-inch leaf spring for various axle ratings from 2000- to 6000-lbs. The linked page displays all leaf springs and the filters on the page will let you select the axle...

• Selecting Replacement Leaf Springs for Enclosed Trailer
  
• Leaf springs stretch with use and age and to make sure you match their length, as well as their capacity, you will want to pull one out of the trailer's suspension so you can measure its eye-to-eye length. A well-used spring can stretch as much as 1/2-inch from its original length. If your hanger hole spacing is 25-inches on center then you may well need a 25-1/4-inch like # SP-220275 but the length of your shackles comes into play too. The spring eye dimension should be longer than...

• Correct Leaf Spring for Trailer with Lippert 3,500 lb Axle
  
• Thank you for the photo! I was able to use the serial number on your axle to determine which is the correct replacement leaf spring for your trailer. For this, you are going to want to use the 3-Leaf Double-Eye Spring part # SP-220275 which is a double eye leaf spring that is 1-3/4" wide, has a 4,000 lb total weight capacity, and a 25-1/4" eye to eye measurement. The measurement you provided of 26" long is correct but the leaf spring needs to be measured while unloaded as it will lengthen...

• Replacement Leaf Springs, Equalizers, and U-bolts for ALKO T52 Axles
  
• Those may not be the original springs on your Springdale. According to ALKO the T52 axle would either have a 5 or 6 leaf spring at a length of 26 inches. To be accurate the springs should be measured with no weight on them because they will otherwise flatten out some leading to a longer measurement. ALKO shows the 4-leaf spring for the T52 at a length of 25-1/4 inches. If you measure it at about 25-1/4 inches with no weight on the spring then you can use # SP-218275 for 5K axles. If...

• Recommended Replacement Leaf Springs For Loadmaster Trailer With 3500-Lb Axle
  
• We do have a leaf spring that will work for your trailer but it is designed for a 4,000-lb axle It is part # SP-051275. This is a 4-leaf double eye spring and it measures 26-inches center-of-eye-to-center-of-eye. You may notice a little difference with these springs on your trailer. The ride could be a little stiffer, and when the trailer is empty it may bounce a little more but the length of the springs will work for you. If you are wanting to use a shorter leaf spring you may...

• Bolts Needed To Install Slipper Springs
  
• For the spring eye you would use the Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long # 166079, but slipper springs don't have the second spring eye, so a bolt is not used on the back end. You can also use a wet bolt like # 126B2, for less friction. The Shackle Bolt with Locknut for Double-Eye Springs - 3" Long # 166081 are for use with the spring and shackle straps used with a shackle straps on a tandem setup with an equalizer but it could be used for the springs and the...

• Double Eye 26 inch long 3 Leaf, Leaf Spring Availability
  
• The closest match that we currently have to the leaf spring that you are looking to replace is either part # SP-124275 which is rated for 2,000 lbs or part # SP-051275 which is rated for 4,000 lbs. They both are double eye leaf springs that are 26 inches long but they look like they fall outside of your weight range and they both have 4 leaf springs instead of 3. For a 2,500 lb 3-Leaf Double-Eye Spring we have part # SP-219275 which measures 25-1/8 inches on center. For a 3,500 lb...

• How to Determine the Correct Replacement Double-Eye Trailer Leaf Spring for a Boat Trailer
  
• A trailer leaf spring will wear out over time and the wear will likely lengthen the spring. Therefore, the correct replacement leaf spring will likely be shorter than the leaf spring you have on your trailer now depending on the amount of wear that has occured. If the leaf springs you have on your trailer now are 26-1/2" long from the center of each eyelet, I recommend using a 26" long leaf spring like part # SP-124275 for 2,000 lb, part # SP-051275 for 4,000 lbs, part # SP-256275...

• 26 Inch Leaf Springs for Axles Rated at 5,200 lbs
  
• We do have a solution for you although we don't carry a leaf spring for a 5,200 lb axle that has the same dimensions as Leaf Spring # SP-051275. What does have the same dimensions is the 26" Double-Eye Spring for 6,000-lb Trailer Axles # SP-053275 which will work for you despite being rated for more than your axle's capacity; they are rated close enough to your 5,200 lb axles that you won't have to worry about the springs causing a stiff ride.

• Replacement Spring for Boat Trailer
  
• Thank you for the information. When it comes to replacement springs, the eye-to-eye distance and weight capacity are the most important factors. Springs flatten - or stretch - over time, so your 26-3/4 inch springs were likely 26 inches. There are two possible four-leaf options for you, and the right one will depend on your axle's weight capacity. Spring # SP-051275 is for an axle with a capacity of 4,000 lbs. The other spring is # SP-124275, which is for an axle with a capacity of...

• How to Pick Out Replacement Leaf Springs for Boat Trailer
  
• When replacing trailer leaf springs we strongly recommend you replace them in pairs. I would urge you to get a set of matching properly rated springs for your trailer as soon as possible. If you look on the frame of your trailer there should be a plate with the trailer VIN number and the axle capacities of the trailer. You will want to pick leaf springs that are as close to the axle capacity as possible. You will want to also measure the distance from eye to eye of your old leaf springs...

• Tips for Picking Out Travel Trailer Leaf Springs to Replace 20 Year Old Springs that Measure 26 in
  
• Leaf springs do have a tendency to stretch as they age. With springs 20 years old I'd imagine they've stretched a decent amount. Most likely you'd need a spring in the 25-1/8 inch to 25-1/4 inch range but we also need to determine capacity axles you have so that we can pick you out the correct rated spring. Due to the age of your trailer suspension it would be a great idea for you to replace all the springs now too. If you aren't sure of the axle capacity let me know the diameter of the...

• Spacing Measurements for Tandem-Axle Trailer Hanger Kit APT5 & Spring SP-051275
  
• When setting up a new trailer suspension it is best to do a mock-up (by clamping or tack welding the parts in place) to allow you to see how the system functions. There are so many variables that is best to test. Typical spacing dimensions for 25-1/8-inch springs are shown in the chart on the page for # APT5. Since the springs you intend to use, 4-Leaf Double-Eye Spring # SP-051275, are 7/8-inch longer than those listed in the chart, you will want to increase the hanger spacing approximately...

• How to Replace 26-1/2 inch Leaf Springs on Trailer
  
• Since old springs tend to stretch out about 1/2 inch you would want a 26 inch spring to replace what you have. Which we carry several. See the attached link. You would need to select the filter on the page that has the axle capacity that matches your trailer and it would be the correct fit. The part # SP-051275 that you referenced is for 4,000 lb axles.

• Will these leaf springs work SP-051275
  
• There a few more measurements that are needed off of your current leaf springs to guarantee that you will find the correct replacement leaf spring. I have attach a diagram that will show the other measurements that are needed. You have the first measurement with the eye-to-eye distance. To find the correct replacement you will also need the spring height, measured from top of the center of the spring to the center of the eye. Also needed is the distance from the spring center to the...

• Replacing Slipper Springs With Double-Eye Springs
  
• There are no U-bolts to attach the slipper part, I recommend replacing your slipper springs with double eye springs. In order to do this you need to know the weight rating of your axle as well as the length from center eye to center eye so you can properly place your hangers. For example, the 4-Leaf Double-Eye Spring # SP-051275 measures 26 inches from center of spring eye to center of spring eye and has a 4,000 lb capacity; you will need to find springs that match your trailer's capacity...

• Recommended 26 Inch Leaf Springs for 3750 lb Tandem Axle Boat Trailer
  
• The 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 26" Long # SP-051275 will be the closest fit for your 3750 lb axle. Having leaf springs rated slightly higher is normal because you will be limited in capacity by the weakest component on your trailer and normally you want that to be your axle. These springs will not be too strong for that axle as to cause too firm a ride.

• 25-1/4 inch Leaf Spring Recommendation for Travel Trailer with Tandem Axles
  
• 20 year old leaf springs on a trailer could easily stretch 3/4 of an inch. Going with a 25-1/4 inch spring like you mentioned would be great. Since your springs are 3 inch in diameter that would indicate that most likely you have a 5,200 lb axle as that's a very common rating for that size. For a 25-1/4 inch length spring we have the part # SP-218275 which has a 5,000 lb capacity. # SP-220275 which has a 4,000 lb capacity, and # SP-115275 which has a 6,000 lb capacity.

• Recommendation For Hanger And Shackle Spacing For 26 Inch Leaf Springs
  
• I contacted the manufacturer to confirm what you need to do for installation of the 4-Leaf Double-Eye Springs, Item # SP-051275. The hangers should be spaced at approximately 30-1/4 inches for 26 inch leaf springs. The shackle point from the bottom of the equalizer should be pointing upward for the front and back at about 60-70 degrees. Please contact us if you have other questions.

• Can Boat Trailer Replace Slipper Springs With Double Eye Springs?
  
• Yes, you can replace your slipper springs with double eye springs. The Double-Eye Spring # SP-051275 measure 26 inches from center of spring eye to center of spring eye and would work for you; these have a 2,000 lb capacity each though you will need to find springs that match your trailer's capacity as closely as possible. The other thing you would need is a hanger kit such as # APS3, which has 1-1/2" tall front hangers, 1-1/4" tall rear hangers, and 3-1/8" shackle straps. The correct...

• Replacing 4-Leaf Double Eye Springs with 6-Leaf Double Eye Springs on 4,400 Pound Axle
  
• Installing slightly over-rated leaf springs on a trailer shouldn't cause any damage to the axle or other suspension components. There is no reason to replace the axle on your trailer with a higher-rated unit so that it matches the springs. Over-rated leaf springs may cause a bit of a rougher ride but I suspect that the "springy" experience you described has more to do with the noticeable difference between old worn-out springs and brand new ones that are in good condition. The difference...

• Hanger Placement for Trailer Using Both Double Eye and Slipper Spring Leaf Springs
  
• Normally you don't see double eye and slipper springs on the same trailer but if you don't want to change springs then we will have to work with what you have. The only issue is that most modern trailer double eye springs are 1-3/4 inches wide so a 2 inch hanger would allow for too much play unless that slack is taken up. To determine the spring hanger placement we first need to figure out where the center point between the 2 axles needs to be. To do that take a look at the picture I...

• Clearance Requirements Between Trailer Tires and Fenders and How to Calculate Tandem Axle Positions
  
• As far as clearance between the tops of the tires and the bottoms of the fenders look for at least 3 inches to account for the suspension travel. As far as the placement of the axles it all depends. Take a look at the picture I have included that shows how to calculate axle position. You might have to do some estimating but it will at least get you close to the ideal positioning.

• Replacement Trailer Leaf Spring Recommendation for Trailer with 26-1/2 inch long Springs
  
• Since trailer leaf springs tend to stretch out over time when you pick out a new one you want to go with one that measures just slightly shorter than what came off the trailer. Since yours is 26-1/2 inches a 26 inch long spring like the # SP-051275 would work well if you need a 4k rated leaf spring. If you need a different axle capacity you would need to check out the link I attached that has all of the 26 inch long springs we carry.

• Leaf Spring Recommendation for 10k Trailer with 26-1/4 inch Springs
  
• Your 10k trailer with dual axles is going to have two 5k rated axles (most likely). The only double eye spring we have that would match that capacity is the part # SP-218275 but it would be about an inch too short as it measures 25-1/4 inches. You should note that old springs typically stretch out around 1/4-1/2 inch as they flatten over time. Dimensionally the correct spring we have would be the part # SP-051275 as it is right at 26 inches. This is for a 4k axle though. Best...

• How to Get Clearance for Slipper Spring Compressing on Top of Wheel Well
  
• To answer your first question a double-eye spring would not compress less than your current 4-Leaf Slipper Spring w/ Open Eye End # SP-264275 and I do not recommend going with a higher-rated spring than what your trailer is rated for as that will make your ride very stiff and unpleasant. The only real options you have to get more clearance are to raise the fender if you can or add one that has more height (I have linked our selection of fenders for you to check out) or to cut off your...
