Expert Answers about Trailer Leaf Spring Suspension


  • Does TrailerLegs Tire Saver Stands for Trailers Require Leaf Spring Suspension
  • The TrailerLegs Tire Saver Stands for Trailers w/ Leaf Spring Suspensions # 326-TRLLG-4 were designed to be used with trailers that have leaf spring suspension. They can't be used with torsion axles suspension but if for some reason you had a straight axle with now suspension this could work.

  • Can I Convert My Galvanized Boat Trailer With A Rectangle Axle To Leaf Spring Suspension
  • Hello Robert. It sounds like you are trying to convert your trailer over to leaf spring suspension. Does your trailer currently use a torsion axle? Because leaf spring suspension cannot be added to a torsion axle. If it is just a straight rectangle axle, it is possible to add leaf spring suspension. Spring seats would need to be welded to the axle. We do not offer any spring seats for a square axle, but a spring seat like part # TRSS300 could potentially be modified to fit. You will also...

  • Recommended Leaf Spring Suspension Enhancement for Trailer
  • The SuperSprings Mounting Kit for OEM Leaf Springs Above the Axle # MXKT is designed to be used with a SuperSpring Custom Suspension like the # SSA28 and allows you to mount the springs above the axles instead of below them with the rest of the leaf spring pack. These springs are designed for a truck and not a trailer, so it's really not going to be a solution that would work for you. If you can tell us more about your trailer, like the axle capacity and how many axles there are, we can...

  • Replaced Leaf Springs On Tandem Axle Boat Trailer And The Rear Springs Are Tilting Rear Axle Forward
  • If you do not have the boat on the tandem axle trailer, what you have mentioned is how the trailer suspension will look without a load on it. The equalizer will be up in the rear and the rear spring will be tilting the axle forward. The reason is because the rear tires on your boat trailer are made to scrub when turning and with the suspension set up this way it keeps the majority of the load on the trailer from being put on the rear tires. If the boat is on your trailer and the trailer...

  • Will Installing Timbren Silent Ride Suspension Help Improve the Suspension for 7K Tandem Axles
  • The Timbren Silent Ride Suspension for Tandem Axles, # TSR14KT01, was designed to eliminate the problems that traditional leaf spring trailer suspension encounter on travel and 5th wheel trailers. (The Silent Ride system will bolt right up to the frame of your trailer and allow your tandem 7k axles to connect to the Timbren system. The Silent Ride system uses Aeon rubber springs to supply cushion and absorption of road shock. Tension from the Aeon rubber springs, as well as absorbing shock,...

  • How to Determine if Leaf Springs Will Work on 7,000 lb Trailer Axle
  • We may have an option for you but don't have any way to know the current suspension or leaf springs you have on your current trailer axles. The two leaf springs we carry for a 7,000 lb axle are: - Double-Eye Suspension: 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles - 24-7/8" Long # e64SR - Slipper Spring Suspension: 5-Leaf Slipper Spring w/ Hook End for 7,000-lb Trailer Axles - 26-5/8" Long # e74SR In order to determine if these will fit you will need to measure the length from...

  • Can you Explain Why the Roadmaster Comfort Ride Leaf Spring Kit Does Not Use a Suspension Equalizer?
  • The Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2570 that you are looking at is designed to allow each axle to act independently of the other, similar to the way torsion axles work. While it uses slipper springs to achieve this on your trailer traditional tandem axle slipper springs systems will still offer an Equalizer like # HAP-203-01. I do recommend using equalizers with your leaf spring suspension whether you have double eye springs or slipper springs, as they allow...

  • Will Using Leaf Springs With A Different Amount Of Leaves Be Okay On My 2018 Vanleigh 5TH Wheel?
  • The number of leaves on a leaf spring is not the only determining factory in the amount of weight it can handle. The thickness of each leaf as well as what the leaf is made out of can affect the weight rating and performance of the spring. The Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2570 does use 5 leaves that are 3/8" thick. Each spring is rated for 3,500lbs which is 7,000lbs per axle. This kit upgrades your suspension by allowing the axles to act independently of...

  • 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...

  • 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...

  • Is There Similar Product To Timbren Axless-Less Suspension Compatible With A Triple Axle Setup
  • Axles are there to support the weight of the trailer so increasing the number of axles would not result in a softer ride quality like you're thinking. The suspension, whether it's leaf springs or Timbrens, would be the determining factor in ride quality. There isn't a similar product out there to match Timbren's axle-less suspension that could be used in a triple axle setup. A Timbren Axle-less suspension like # ASR2KHDS03 would be a great option if you were going off-road since leaf...

  • Replacement Leaf Springs for Triple Axle Boat Trailer with 3500-lb Axles
  • The Timbren axle-less suspension systems like # ASR35HDS02 cannot be used in triple-axle configurations so they would not work for you. The linked page displays double-eye leaf springs for 3500-lb axles. These are available in three eye-to-eye lengths, 23-1/8, 25-1/8 and 27-inches. Please note that a well-worn spring tends to elongate, so when you remove the two leaf springs from the axle to measure them keep in mind that those springs, when they were new, could have been shorter than...

  • Will Leaf Springs Flatten Over Time to Cause Trailer Lean
  • The leaning that is occurring in your 2016 Stryker could be a number of issues, and you asked a good question about your leaf springs. Since these do flatten out (essentially elongating) over time, that could very well be the issue, but there is no way to definitively say what the issue is. The problem could also be other suspension components being worn out so the only way to truly determine what is causing the trailer to lean is to take it to a quality trailer repair shop and have them...

  • Recommended Suspension Enhancement For Dog Trailer That Rides Rough
  • Hey Tyler, For a 3,500lb axle SuperSprings International has you covered with their SumoSprings Helper Spring line, you'll just need to see if the axle is above or below the leaf springs. If the axle is below the leaf springs you have an overslung suspension and need part # TSS-107-40. If the axle is above the leaf springs then you have an underslung suspension and need part # TSS-106-40 instead. These jounce springs will provide a night and day difference for your trailer's ride quality...

  • Can Correct Track and Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks Fit Together

  • 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,...

  • Parts Needed to Convert a Single Axle Marine Master Trailer to a Tandem Axle Trailer
  • We do have tandem axle suspension kits, leaf springs and u-bolts to convert a single axle trailer to a tandem axle trailer, but the conversion will be a little more involved than just adding a second axle. To ensure you purchase the correct parts, you will want to look at your current axle and suspension. You will need to know the axle weight capacity, axle diameter and leaf spring dimensions to choose the correct suspension parts for a tandem axle trailer. I have attached a link to all...

  • 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...

  • 2020 Ford F-150 Suspension Upgrade to Help Reduce Sway
  • Whenever you tow a trailer, or put a lot of weight on the rear of your F-150 the leaf springs start to flatten out, and typically the ride geta very stife. Not to mention the sag in the rear end. The back goes down, and the front raises up. Which leads to less traction on the front tires, reduced braking and porpoising. To help the sway and bounce when towing your trailer I recommend the RoadActive Suspension Custom Leaf Spring Enhancement Kit. For 2WD # RAS3611-B, and for 4WD # RAS3611-Y. This...
