Expert Answers about Trailer Leaf Spring Suspension

• Replacing a Broken Leaf Spring on a 2007 Starcraft 2406 Pop Up Trailer
• When replacing a broken leaf spring on your trailer there are a few things to note. The most important part about a leaf spring being compatible with your trailer is that it is rated for at least the same weight capacity as your trailer axle. If it is rated lower you could overload it. A higher rated leaf spring would work but it would also make your trailer suspension stiff. Other than weight capacity you simply need to make sure that it has the correct width, is the same style, and has...

• Replacement Trailer Suspension For Single Axle Boat Trailer
• From the looks of the photo you sent it does not look like you have an OEM suspension system on your boat trailer. I recommend securing the suspension rail to the trailer frame in a more secure manner like drilling and using bolts so that it does not shift. 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...

• Recommended Replacement 3-Leaf Trailer Leaf Spring for 6 x 12 Utility Trailer
• Leaf springs are most often 1-3/4-inches wide but larger widths can also be found, up to 3-inches for very heavy-duty suspensions. We do not offer any leaf springs in a 1-1/2-inch width. It is likely that yours are indeed 1-3/4-inches wide so you might want to double-check. I have linked you to our main page for 1-3/4-inch wide 3-leaf springs. You can click on the filters on the page to narrow the results down to the items with the correct dimensions and capacity for your set up. First,...

• Replacement Leaf Springs and Suspension Parts for 1962 Forester Camper Trailer
• Trailer makers do not maintain specs on items like suspension components but it is not difficult to identify correct replacement suspension parts like leaf springs and shackle straps. It is usually best to remove one of the leaf springs to measure it when it is not under tension. This gives the most accurate eye-to-eye dimension. Also note that a well-worn leaf spring can actually stretch a bit. Leaf springs can easily elongate as much as 1/2-inch, sometimes more, if they are very old...

• How to Measure to Select Correct Replacement Trailer Leaf Springs
• It is difficult to accurately measure the length of a leaf spring when it is still under tension in the suspension system. You will get a more accurate eye-to-eye length measurement if you remove the spring from the suspension. The leaf springs we offer for 3500-lb-rated axles come in several lengths, including the longest at 27-inches. While it is possible for springs to become elongated from use a 3-inch gain in length is not possible. Well-worn springs can become up to 3/4-inch longer...

• Replacement Leaf Springs For Tandem Trailer With 6,000 lb Axles
• If you are bottoming out with your trailer it can be caused by a weak or broken suspension causing the problem. You want to check for all of the components for any signs of obvious damage. Since leaf springs may flatten out a bit over time you will need to measure the center-of-eye-to-center-of-eye to find the right leaf springs. This should be done when the spring is off the trailer or with the trailer raised so there is no weight on the spring. One of the double-eye leaf springs we...

• Replacing/Upgrading The Suspension On A 2007 Colorado Tandem Axle 5th Wheel With LRE Suspension
• It sounds like you are definitely on the right track here. The # MR79ZR is indeed the correct suspension upgrade kit for your 2007 Colorado 5th wheel with LRE suspension. Moryde makes a fantastic suspension upgrade kit. The heavy duty shackles and wet bolts are highly durable and will last a very long time as long as you keep them properly greased. The shear spring # MR79UR is also correct for this setup. The leaf springs might be a bit more tricky, since you are measuring them under a...

• How to Determine Correct Replacement Double-Eye Leaf Springs for EZ-Loader Boat Trailer
• It is tough to determine the actual length of a double-eye leaf spring when it is still installed in the boat trailer's suspension; it is tougher still if the weight of the boat is on the suspension. In fact, when a leaf spring is old and well-worn, it can actually stretch or elongate slightly, meaning that if you pulled it completely out of the suspension and measured its eye-to-eye length the measurement you get could actually be longer than when that spring was brand new! We are usually...

• How to Tell When Travel Trailer Leaf Springs Need to be Replaced
• A leaf spring should be replaced if it is badly rusted, has cracks or breaks in its leaves or if it is sagging. A 14-year-old travel trailer could certainly be in need of new leaf springs. The keys to selecting correct replacement leaf springs are to match your axle capacity, number of leaves and spring size. Most axles will have a plate or sticker that indicates the axle's weight rating. It is best to remove a spring from the suspension to check its eye-to-eye length. A spring that is...

• Replacement Suspension Parts for Tandem Axle Stock Trailer
• You will want to completely remove one of the double-eye leaf springs from your trailer suspension to measure its eye-to-eye length when it is not under any tension. Also, note that if it is very old and very worn the spring may have actually elongated slightly. Well-used leaf springs can stretch from use and it is not unusual to find a very worn spring is as much as 1/2-inch longer than when it was new. You may find that the new matching springs for your axle rating are a little shorter...

• Replacement 6-Leaf, 7,000LB Double Eye Spring For a 2012 Dutchman Voltage 3950 Toy Hauler
• The 6-Leaf Double-Eye Spring # e64SR is currently our only 7,000lb spring we carry. This has an eye to eye measurement of 24-7/8". Since the springs on your 2012 Dutchman Voltage 3950 are likely sagging over the years of use you will want to measure the length of your spring from the center of the eye to the pin in the center of the leaf spring along the radius. If you come up with 13-3/16" this is going to be the correct spring for you. I recommend replacing your shackle straps and bolts...

• Recommended Replacement Leaf Springs for Ranger Boat Trailer with 3000-lb Axles
• It is tough to get a correct eye-to-eye measurement on a double-eye leaf spring when the spring is still installed in the suspension. It is much better to measure for a replacement leaf spring by removing it first. Also, if a spring is very old and well-worn it can actually become longer than it was when new. Years of use can cause a leaf spring to elongate by as much as 1/2 to 3/4-inch. In a 1-3/4-inch wide double-eye spring rated for a 3500-lb axle, we offer the 4-leaf # SP-210275 which...

• Replacing Leaf Springs on Old 1,500 Pound Boat Trailer
• When picking out new trailer leaf springs it is important to closely match their length with your existing sets. Leaf springs will definitely stretch/lengthen a bit over time (around an inch or so at most) but the 20-3/8 inch long 3-Leaf Double-Eye Springs # e84SR that you referenced are likely much too short for your current suspension setup. Using these leaf springs would require you to completely change the suspension, including cutting off the current hangers and welding on new ones...

• Replacement Suspension Parts for Tandem Axle Travel Trailer
• The 3,500 lb axle is the most common size 2-3/8 diameter axle, but it isn't the only one. If you have the odd-ball 2,800 lb axle, then you will have the different bearings, seal, and hubs you referenced because of the spindle dimensions. Each axle is rated individually by the manufacturer and the spindles are in the case the reason for the lower rating. The springs you currently have are not available from our manufacturers in the size. You will need to replace the hangers as well...

• How to Find Replacement Leaf Springs for 2012 Keystone Cougar 27RLS
• The size of the replacement leaf springs on your 2012 Keystone Cougar 27RLS should be the same as what you have now. To be more specific, you need to match the length as well as the axle capacity. Based on the weight of your trailer it looks like you have 3,500 lb axles but I would check the axle tag to be sure. The length is something you will have to measure. The standard is the spring eye to spring eye measurement. You can also use the flat measurement since your leaf springs will...
