  • Can I Buy Trailer Axles That Come With Spindles and Brakes
  • We do offer trailer axles that already have the spindle and some even come with brakes! I do not recommend modifying the length on any trailer axles, though, because they have been manufactured for a specific purpose and any modification could cause something to be out of balance or uneven. Since 3,500 lb axles are very common, I recommend going with the Trailer Axle # e43SR that comes with electric brakes. To make sure that this axle will fit your trailer you will want to take the spring-center-to-spring-center...

  • Do You Carry Any Replacement Axle Beams For a UFP Torsion Axles?
  • I can only help you find a possible replacement axle system like the Timbren Axle-Less Trailer Suspension w Idler Hubs # A35RS545. We currently do not carry any axle beams or torsion axles. When I reached out to Dexter who acquired UFP axles they were not able to provide me with any information about your axle with the serial number you provided. I would need to know the weight rating for your trailer along with the mounting measurements for the axle and hubs to determine if we have a Timbren...

  • How to Determine Whether or Not You Can Flip the Axles on Your Trailer?
  • There are a couple of things that you'll need to know that will determine whether or not you can flip the axles on your 2017 Keystone Sprinter 5th Wheel. You will need to have round axles with either 2-3/8" or 3" diameter, and your current suspension system must be installed below the axle. You'll want to check the specs on the plate or sticker in the middle of your axle to determine what type of axles you currently have on this trailer to determine if your trailer meets these requirements. If...

  • Availability of Replacement Axles for a 91 Shadow Cruiser 5thWheel Travel Trailer
  • The Timbren Axle-Less Suspension, like # A35RS545E will be the best option in changing out your trailers axles. Unfortunately, we do not carry torsion style axles. The bearings that you supplied shows that your axles look to be rated at 3,500 lbs for each axle.

  • Available Types of 2K-Rated Trailer Axles
  • We do offer standard beam axles for leaf spring suspensions and also Timbren axle-less suspension systems rated for 2K but due to shipping size and weight restrictions we cannot ship torsion axles. A major benefit to the Timbren systems is improved ground clearance under the trailer. Since there is no axle tube you gain additional ground clearance, or you can choose to have a lower trailer deck height if that suits your application. The linked page displays all 2K axle kits. You can...

Links to both types of kit are provided for you. The Timbren systems offer the advantages of providing an independent suspension for each side of the trailer and of providing much better...

  • SumoSprings Trailer Helper Springs Recommendation for OverSlung Trailer Axle
  • Drop axles don't drop the distance between the trailer frame and axle as basically the drop is after the suspension and between the spindle. So the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket # TSS-106-40 would install just fine on a drop axle. But sounds like you have an overslung axle based on the distance between your leaf spring and trailer frame. So for that you'd instead want the part # TSS-107-40.

  • Lift Kit for 5,000 lb Dexter Torsion Axle
  • For your Dexter 5,000 lb Torflex torsion axles the lift kit that will work - so long as your axles are side-mounted #11 Torflex axles - is the Torflex Lift Kit # K71-724-02. Though this kit is meant for tandem axles - there aren't kits available designed for three axles - it will work for your trailer if it had a trio of #11 Torflex axles; you would just need to order two of them in order to get the needed parts for your trailer. I've added a link to a video review of this kit for you...

  • Are Rubber Style Suspension Equalizers Available for a 7,000 lb Tandem Axle Car Trailer
  • It is possible that we have a rubber suspension equalizer that can be added to your 7,000 lb tandem axle trailer. The axle spacing will be needed to determine which rubber equalizers, if any, will work on your trailer. This style of equalizer is designed for trailers with two 3,000 to 8,000 pound axles, depending on which setup is needed. If your axle spacing is 33 inches on center the E-Z Flex Heavy Duty Rubber Suspension System, # K71-652-00, would be the correct equalizer system for...

  • Trailer Axle Wiring for Brake Assemblies at the Axle
  • Sounds like you are describing the brake output circuit wires that came with your new trailer axles. Basically the wires of the axles need to run from the main brake output circuit feed of your trailer wiring to each of the trailer brake assemblies. If you check out the picture I attached you will see how they are typically wired. The brake assembly wires can be used for either ground or power. It doesn't matter which you pick as long as the other wire is connected as well to the opposite...

Kit # K71-384-00 works for a 2-3/8-inch diameter axle and kit # K71-385-00 works with 3-inch diameter axles. Unfortunately we do not have a kit for a 1-3/4-inch diameter axle.

  • Can the Dexter Trailer Axles # T20BTR-EZ-6048 have the Spring Seats Moved to Top of Axle
  • We don't sell the Dexter Trailer Axles # T20BTR-EZ-6048 with the spring seat on top of the axle so that it could be installed overslung. But, what you can do is get the # TRSS175 and then have a qualified welder install this spring seat on the top of the axle so that you could install it in the configuration you need to.

  • Can Straight and Cambered Axle be Used on Tandem Axle Trailer
  • I would recommend sticking to matching axle styles as much as possible. Having a totally straight axle with a cambered one would most likely give you tire wear/alignment issues. The straight axle is not very common at all so best solution for you would probably be to get two new cambered axles.

This feature allows a 4-inch lower deck height for more interior headroom and easier entry. We do offer the axle-less Timbren trailer suspension kits that offer drop. Examples include the 3500-lb-rated Timbren kit # A35RD545E which features electric brakes with 5-on-4-1/2 hub/drums and the idler hub kit # A35RD545. These suspension kits bolt (or weld)...
