Expert Answers about Trailer Axles


  • Comparing Timbren Axle-Less Suspension Systems to Standard Beam Axles for Off-Road Trailer
  • The 2000-lb-rated Timbren axle-less system # A20RS545 will be fine for your application. Since your trailer will weigh below this 2000-lb maximum there will be no real benefit from moving to a higher-rated system. That might even produce rougher handling when the trailer is unloaded. One of the additional benefits of a Timbren axle-less system is ground clearance. There is no axle beam under the trailer and no leaf springs so you can achieve better ground clearance under the trailer. Timbren...

  • Comparing Leaf Spring Axles, Torsion Axles, Dexter and Hayes/AL-KO
  • I personally would not have any reservations about using a torsion axle. Dexter is a leader in the industry but Hayes/AL-KO are quality as well. It seems to be easier to get parts for Dexter axles and they tend to cost less. On a torsion axle you will want to be cautious not to overload it (of course this goes with leaf spring axles too). The suspension components on leaf spring axles are easier to replace as well but a torsion axle is going to give you good performance provided you keep...

  • Comparing 7K Hydrastar Disc Brake Kits for Tandem and Triple Axle Trailers
  • The Hydrastar Disc Brake Kit w/ Actuator for Tandem Axle Trailers - 7K is part # HSE7K-T1 is for tandem axle trailers and the Hydrastar Disc Brake Kit w/ Actuator for Triple Axle Trailers - 7K is part # HSE7K-TR1 is for triple axle trailers. The only difference between the two is that you'll get an extra hub/rotor with the latter since it's designed for triple axle trailers.

  • Timbren Axle-Less Suspension Comparison & Recommendation For A Custom Overlanding Trailer
  • The difference between the Timbren Axle-Less Trailer Suspension System ASR1200S01 and the Timbren Axle-Less Trailer Suspension System # ASR1200S02 is that ASR1200S01 is designed for off-road tires, and # ASR1200S02 is made for regular tires. The Dexter Trailer Idler Hub Assembly # 8-91-05UC1-EZ is the appropriate hub assembly for ASR1200S01 and # ASR1200S02. The Timbren Axle-Less Trailer Suspension System # A12RS440 is the same as # ASR1200S02, but this system also has hubs included. There...

  • What is the Difference Between the Correct Track Trailer Alignment Kit LC87120 and RR23QX
  • The difference between the Correct Track Trailer Alignment and Lift Kit # LC87120 and the Correct Track Trailer Alignment and Lift Kit # RR23QX is that the # LC87120 is for a single axle trailer and the # RR23QX is for a tandem axle trailer. Since your 2018 Jayco Eagle is a tandem axle trailer you would want to use the # RR23QX tandem axle kit. The # RR23QX will contain all the additional parts needed for a tandem axle application.

  • Difference Between Idler and Braking Axle
  • A brake axle would have brakes, either electric or hydraulic drum or disc brakes while an idler hub would have no brakes. Many times, a tandem axle trailer will have one braking axle and one idler axle. The 3500 lb capacity # 35545I-EZ-89 axle you were looking at comes with idler hubs, but because it has brake mounting flanges, brake assemblies and hub/drums could be added at a later date if necessary. To find a replacement axle, you'd need to measure the hub face to hub face dimension...

  • Comparing Breakaway Kits for 2 Axle and 3 Axle Trailers
  • It honestly just boils down to what the manufacturer has tested and approved for each battery. For example, the Tekonsha Push-To-Test Trailer Breakaway Kit # 50-85-313 is rated for up to 3 axles while the Hopkins Engager Push-To-Test Trailer Breakaway Kit # 20099 is only rated for up to 2 axles. Breakaway kits are designed to stop your trailer in a worst-case scenario. Since this is something that is used for emergencies only I highly recommend swapping out your current system with one...

  • What is the Difference In Electric Trailer Brakes for 5,200, 6,000, and 7,000 Pound Trailer Axles
  • First, a 5,200 pound axle is a de-rated 6,000 pound axle so they take many of the same parts. Some 7,000 pound axles also take the same size parts. The difference is the size or ability of the magnets. Sometimes you will see the same type of magnet for 5,200 or 6,000 pound axle brakes. Some 7K axle brakes will also fit. A brake for a 5,200 or 6,000 pound axle should not be used on a 7K axle (unless it also fits 7K axles of course) because the magnet is not strong enough to provide the proper...

  • What Is The Difference Between Roadmaster Comfort Ride RM-2460-2570 and RM-2460-2580?
  • I would be happy to help! The Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers - Tandem 7K Trailer Axles # RM-2460-2570 is for trailers that have 7000lb tandem axles, and use springs that have a 3500lb capacity each (one spring on each end of the axle). In contrast the # RM-2460-2580 is for trailers with 8000lb tandem axles, and uses springs that have a 4000lb capacity each (one spring on each end of the axle). Now both 7000-8000lb axles are 3" in diameter, but I...

  • Can Axle Weight Rating be Increased with Upgraded Leaf Springs and Hubs
  • To upgrade your axles to a 5,200 lb weight rating you'll have to swap out your 3,500 lb axles for 5,200 lb axles like part # e55SR that comes with electric brakes and has 95" hub-face and 80" spring-center measurements. Unfortunately you have to upgrade everything to get the higher weight rating as the axle tube itself will need to be stronger. And even after you upgrade the axles it doesn't necessarily mean your trailer can handle more as the trailer frame is also a factor when it comes...

  • Comparing 95" Trailer Axle Beam with Easy Grease Spindles and Dexter Trailer Axle Beam with E-Z Lube
  • The Trailer Axle Beam with Easy Grease Spindles part # e68GR is made by Axle Tek and the Dexter Trailer Axle Beam with E-Z Lube Spindles part # 7359765 is made by Dexter. That said, they both have the same specs and features, you'll just save a bit of money with our house brand so that's what I recommend. That said, if you want to stick with the name brand item in Dexter, you won't be disappointed there either.

  • Which Trailer Axle Company is Best, Lippert Dexter or Al Ko
  • I would recommend Dexter Torflex axles the highest for torsion axles. And then put Al Ko and Lippert at about the same in quality. I was searching around online and the common consensus among the trailering forums is that the Dexter axles are definitely the ones to go with if at all possible. Lippert is a great company that does a ton of things really well, but Dexter does axles the best.

  • Comparing Roadmaster Comfort Ride Shock Absorbers for Triple Axle Trailers to Tandem and Add-On Kit
  • You are correct that they are the same thing. The Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers # RM-2460 combined with the Roadmaster Comfort Ride Add-On Kit # RM-2460-50 will have the same parts as the Roadmaster Comfort Ride Shock Absorbers for Triple Axle Trailers # RM-2460-3. So there is no difference aside from that fact that one is for tandem axles with the add-on kit to upgrade for triple axles and the other comes with everything in one kit for a triple axle trailer.

  • Can Two Single Axle Correct Track Kits Be Used in Place of Tandem Axle Kit
  • Yes, you can use two of the Correct Track Trailer Alignment and Lift Kit - Single Axle # LC87120 and it will be the same as the tandem axle kit # RR23QX. The tandem axle kit comes with 8 suspension plates and 16 alignment correction plates along with the hardware. Since the # LC87120 has 4 suspension plates and 8 alignment correction plates it would be the same if you ordered two. For leaf springs, you will want to make sure you match the current capacity and length. The length is measured...

  • Comparing etrailer Tailer Axle # e84YR To Dexter 6047 2,000LB Trailer Axle
  • The etrailer Trailer Axle with Idler Hubs # e84YR is different than the 2,000lb Dexter 6047 axle. This axle is closer to the Dexter # T20BTR-6048 with the 48" spring center to spring center measurement. Both have 60" hub faces with a underslung design. The only difference to the 6047 is going to be the spring center distance.

  • Timbren Axle-Less System vs. Torsion Axles for a Sail Boat Trailer
  • I recommend the Timbren Axle-Less Suspension System # ASR2000S01 over a torsion axle for your trailer for a few reasons. First, the Timbren System increases ground clearance without increasing your trailer height. The Timbren System is also easier to replace as you can replace one spring at a time. They also operate independently of one another to minimize bounce for a smoother ride compared to the torsion axle system. An E-Z lube spindle is included with the system, but a Trailer Hub...

  • What is the Difference Between Dexter 6k and 7k Electric Drum Trailer Brake Assemblies
  • Electric drum brake assemblies for 6k and 7k axles both use the same 5 bolt mounting pattern. The 7k brakes will have a stronger magnet and will provide more braking. If used on a 6k axle a 7k brake assembly can be too aggressive but it could be used. The literature for the trailer should indicate the axle capacity somewhere. There may also be a sticker or plate on the axle with the capacity. It might also be stamped into the metal of the axle. I have included links to the 12 x 2 inch...

  • Comparing Timbren Silent Ride Suspensions for Tandem Axle Trailers with 2" Square Axles
  • The only difference between the Timbren Silent Ride Suspensions for Tandem Axle Trailers with 2" Square Axles is the axle spread, part # T29MR has a 31" spread and part # T43FR has a 33" spread.

  • Replacing Axles Or Replacing Brakes/Bearings On 2006 NuWa Discover America 5th Wheel Trailer
  • I would be happy to go over the replacement brake/bearing and replacement axle option for your 2006 NuWa Discover America 5th Wheel Trailer. Unless your axles are currently damaged, or for some reason use an obsolete bearing combination I would stick with just replacing the brakes and bearings as that will be much more cost effective. To determine which brakes and bearings your axles use we will need to find the axle rating of your axles, and the bearing combination of your spindles. The...

  • Comparing Lippert Bolt On Shock Kit and SumoSprings Trailer Helper Springs For Single Axle Jayco TT
  • I would be happy to help! For your Jayco Single Axle Travel Trailer a shock kit like the Lippert Bolt On Shock Kit # LC281281 will hands down be the best option to prevent side to side rocking of the trailer. The SumoSprings # TSS-107-40 you were looking at do a similar job, but do not do it quite as well as shocks. Now to determine the correct shock kit for your trailer it will come down to the rating of your axle. If you have a 3500lb axle that is 2-3/8" in diameter I recommend the...
