  • Will the Timbren Axle-Less Trailer Suspension Systems Work With An I-Beam Trailer Frame
  • The Timbren Axle-Less Trailer Suspension System part # A35RS545E will work just fine on an i-beam trailer frame so long as you box in the side of the frame that the bracket for the system attaches to. This essentially means you will have to weld a steel plate on the i-beam frame where the bracket for the above system would install. If you are able to do this then you will have no issue with installation. This part of the process is also somewhat covered in the installation manual as well.

  • Is Suspension Enhancement Required with Trailer Hitch for 2013 Ford Taurus
  • Not necessarily, installing a trailer hitch on your 2013 Ford Taurus like the Draw Tite part # 36492 would be fine without suspension enhancement, but adding it wouldn't be a bad idea if you plan to tow near the vehicle's capacity. For the suspension you'd then want the Air Lift kit part # AL60821 which would give you more suspension support to help level the vehicle.

  • Upgrading Trailer Bushings Greasable Bolts and Equalizer Suspension Parts on a Alpenlite 5th Wheel
  • Installing brass bushings of the proper inner and outer diameter and length is possible. In my experience brass bushings do not last any longer than nylon bushings and they are much harder to find in the correct size. At this time we do not carry brass or bronze bushings properly sized for double eye leaf springs. Upgrading to wet shackle bolts would be a good idea and would increase the life of the suspension components, no matter the construction. You will need to match the length and...

  • Should Trailer Suspension Shackle Bolts Be Torqued
  • When installing suspension components on your trailer there is not going to be a torque setting for the hanger bolts because they really only get tightened down to hand-tight. Going more than hand-tight can pinch the hangers closed and prevent the suspension from being able to move, which will eliminate the support a suspension provides. A standard shackle bolt like part # 9163B uses a mechanical lock nut like # TRFA916DLNZ to prevent it from backing off and would need to be tighten until...

  • If Trailer Is Lifted Off the Ground Will the Timbren Axle-Less Trailer Suspension System Come Apart
  • That should not be able to happen because the rubber spring is attached to the 2 parts. So unless it was already taken apart or something was broken the lower part should not be able to separate from the upper part of the Timbren Axle-Less Trailer Suspension System, # ASR3500S04.

  • Should Loctite be Used when Install Trailer Suspension Parts
  • I would not use any Loctite when installing suspension components on a trailer since the suspension components need to be able to move relatively freely. I would be afraid of getting the thread locker on bolt or something away from the threads. If you were to use a thread locker then use the blue kind. The red is way too strong. The blue will allow nuts and bolts to be removed with hand tools. Maybe I'm just paranoid but for me, I wouldn't use it.

  • When Replacing Trailer Suspension Components does Axle or Frame Need to be Jacked Up
  • To replace suspension components like the Dexter EZ Flex Equalizers # K71-656-00 that you referenced you will need to jack up the frame and not the axle. Lifting the frame allows the suspension components to unweight which gives you ability to unbolt the components without them being under tension and without risk of the suspension falling apart and dropping the frame on the ground. For a jack we have the # ALL620471. Wheel chocks like the part # 337WC24483 wouldn't be a bad idea either.

  • Suspension Won't Settle After Installing the Dexter Heavy Duty Suspension Kit
  • This is a very common issue when installing the Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers part # K71-359-00. What happens is that the shackle is likely flipped on one side. Typically what I do is hook it up and travel at about 5 mph and engage the brake controller if present. If no brake controller then place a short 4x4 in front of the tires and roll forward as they flex over it they will settle in. This should be done after fully greasing the system.

  • How to Set Up a Weight Distribution System on a Ford Expedition with an Automatic Suspension System
  • Yes, a weight distribution system is useful on a vehicle with automatic suspension systems such as your Ford Expedition. Automatic suspensions systems will adjust to ensure that the load is level, but they do not help distribute the weight so that the weight is distributed to all axles on the truck and trailer. I spoke with our contact at Reese and suggested that the best way to utilize the weight distribution system and an automatic suspension system simultaneously is to first, start...

  • How To Determine Correct Leaf Spring Hanger Spacing for the Dexter Heavy Duty Suspension Kit
  • In order to determine the correct leaf spring hanger locations on a trailer you first need to position the axles correctly. I have attached a help article on this part of the process for you. Then, once the axles are correctly positioned you can then mock up the suspension using the equalizers, shackle straps, and leaf spring. The mock up should then give you a good idea where your leaf spring hangers will sit but I cannot provide specific measurements on the Dexter Heavy Duty Suspension...

  • Does Installation of Timbren Silent Ride Suspension for Single Axle Require 2 Inch Square Bar?
  • The Timbren Silent Ride Suspension for Single Axle Trailers w/ 3" Round Axles - 5,000 lbs # TSR5KS02 does not need a cross brace like the Timbren Axle-Less Trailer Suspension System w Electric Brake Hubs - Straight Spindle - 3,500 lbs # A35RS545E for example. On certain trailers, because the Axle-Less spindles aren't connected by a thru-axle may need that additional support and has integrated holes. I reached out to my contact at Timbren and the Timbren Silent Ride Suspension does not...

  • Can You Mix 3,500 Lb and 5,200 Lb Timbren Axle-Less Trailer Suspension Systems
  • The Timbren Axle-Less Trailer Suspension System part # ASR3500S05 is indeed an excellent option to either replace an existing trailer axle or upgrading from single to tandem axles. If you were upgrading, using two axle-less kits would indeed be a walk in the park when compared to welding on new leaf springs hangers. That said, you will need to use two kits with the same weight capacity as the dimension and durometer of the rubber is not the same for different weight capacities. It's better...

  • How to Trailer Suspension Hangers Attach to a Trailer
  • Suspension hangers for trailers like the part # 115917 need to be welded on. There are no options for bolt on hangers so your best option would be to have a qualified welder/fabricator move your current ones. The goal should be for axle place that when the trailer is loaded it would have 10-15 percent of the total weight of the trailer as tongue weight.
