Expert Answers about Trailer Leaf Spring Suspension


  • 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...

  • 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 MORRyde Equalizer Upgrade Fit With Slipper Leaf Springs
  • The MORryde Shock Absorbing Suspension Equalizers # MR27ZR are designed for double-eye leaf springs and won't work with slipper springs, so we'll need to find you an alternative suspension upgrade for your application.

  • Is SumoSprings or RoadActive Suspension Better For 2008 Toyota Tundra
  • For your 2008 Toyota Tundra, between the SumoSprings Solo Custom Helper Springs # SSR-610-54 and the RoadActive Suspension (RAS) Custom Leaf Spring Enhancement Kit # RAS4611TD, the better overall system is the RAS # RAS4611TD. The reason for that is the RAS is an active system which continually reinforces your Tundra's original leaf spring suspension. The force normally put on its leaf springs, either when carrying cargo or towing a trailer like you are, gets transferred to the RAS Enhancement...

  • Will the Roadmaster Comfort Ride Leaf Spring Suspension Kit Lift a Trailer?
  • The Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers item # RM-2460-2570 will be a solid upgrade on your 5th wheel trailer. However, the only way it will provide any lift would be if your current set up has your axles above your leaf springs. If your axles are already below your leaf springs the only option to lift your trailer is the Correct Track Trailer Alignment and Lift Kit item # RR23QX. This kit mounts to your spring hangers and moves the attachment point down...

  • Dexter Heavy-Duty Tandem-Axle Trailer Suspension Kit Compatibility With Leaf Springs
  • If you use the Dexter Heavy-Duty Tandem-Axle Trailer Suspension Kit for 1-3/4" Wide Double-Eye Springs, # K71-449-00, you can choose to remove the bushings from the 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/4" Long # e78SR and swap them with the bronze bushings or you can leave the bronze bushings off and use the bushings in the leaf springs. Leaf springs don't come with a warranty to void other than manufacturer defect, so that is a non-issue.

  • Suspension Lift Kit Options For a 2022 7' x 14' Continental Enclosed Cargo Trailer
  • Based on the information I could find on your 7x14 Continental Vulcan series enclosed cargo trailer I do see it does use a leaf spring suspension with 3,500lb axles. If your axles are placed on top of the leaf springs you can use the Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00 to mount each axle under the leaf springs. This will give you a rise of around 3-4" depending on the height of your leaf springs. Another option is the Correct Track Trailer Alignment and Lift...

  • Will the RoadActive Suspension Work on a 2017 GMC Sierra 3500 with Overload Leaf Springs
  • The extra leaf springs you are referring to are called overload leaf springs. The RoadActive Suspension Custom Leaf Spring Enhancement Kit part # RAS3611-HD will not work with overload leaf springs but the RoadActive Suspension Custom Leaf Spring Enhancement Kit part # RAS3611-CHD will as it is designed specifically for this purpose. I have attached a review video for you.

  • Can Heavier Leaf Springs Be Used On Tandem-Axle Boat Trailer
  • You can use heavier-duty leaf springs like part # e44SR on your tandem axle boat trailer. The dimensions of the springs are the same so you will have no problem installing the new springs.The ride may be a bit stiffer with the new springs but they will work just fine on your trailer. Putting heavier springs on your trailer will not increase the weight capacity for the trailer. Since you mentioned you are replacing the suspension I have attached some links to suspension components that...

  • Are Double Eye Leaf Springs Rated For 8,000 lb Axles
  • Thank you for that detailed information and what I can tell you is that when choosing leaf springs, the actual number of leafs isn't the most important thing, the weight rating and center-eye to center-eye measurement is what you need to know. I have added a cut out from the help article on double eye trailer suspension which I highly recommend reading. We do not carry double eye springs rated for 8,000 lb axles and there is no way for us to know the rating of your currently installed...

  • Will RoadActive Suspension Fit a 2019 Toyota Tundra with Iornman 4x4 Foam Cell Pro Suspension
  • I do have an option for you but it looks like all the Iornman 4x4 Foam Cell Pro Suspension Kits for a 2019 Toyota Tundra include new leaf springs. The RoadActive Suspension Custom Leaf Spring Enhancement Kit is designed for factory leaf springs so I cannot confirm fit. Instead, I recommend the SumoSprings Solo Custom Helper Springs part # SSR-610-40 which will provide extra support when towing/hauling and they are great for retaining factory ride quality. I still can't guarantee fit as...
