Expert Answers about Timbren

  • Best Way to Prevent Sagging Suspension When Towing a Trailer
  • For sag from towing a trailer the best recommendation I can make is actually a weight distribution system. Suspension enhancement will help level your truck while towing. But the advantage to a weight distribution system is that it levels the vehicle by distributing the tongue weight of the trailer up to the front axle of the vehicle as well. This will help greatly with handling and braking, especially in an emergency situation. The best way to pick out a weight distribution system is...

  • Replacement Axle Recommendation For Small Popup Camper
  • The axles we offer are available in 3 lengths. They are 60 inch, 72 inch, and 89 inches hub-face to hub-face, but I may have a solution for you. We do offer axle-less systems that are either bolted or welded to the trailer frame. This would replace the axle and suspension system you currently have on your camper. If you are looking for a system that has a 3,500 lb weight capacity, I recommend part # A35RS545. This is a straight spindle and has a 5 on 4-1/2 bolt pattern. For a system...

  • Hand Brake Recommendation for Timbren Axle Less System
  • To use a hand brake like the part # T2385200 with the Timbren system part # ASR35HDS02 that you referenced you will need to use a hydraulic drum brake with a parking brake linkage. Since the recommended hub/drum is the part # 8-201-9UC3-EZ which is a 12 by 2 inch drum the correct left hand brake assembly would be the # T2351300 and the right hand side would be # T2351200. I also attached a help article on adding hydraulic drum brakes to a trailer for you to check out as well.

  • 3,500 lb Timbren Setup Recommendation for Off-Road Wheels and Tires
  • For a wheel and tire that big your best option would be the Timbren kit part # ASR35HDS02 which is set up for wider tires and also has a 4 inch lift built into it. This is the same 3,500 lb capacity though. That being said we can only safely recommend using trailer rated wheels and tires wit this kit. For just a hub without a drum you would want the part # AKIHUB-655-6-K.

  • Drum Brakes with Parking Brake for Timbren Heavy-Duty Axle-Less Trailer Suspension ASR35HDS02
  • With the Timbren axle-less suspension system # ASR35HDS02 you can install 5-bolt electric drum brake assemblies like # 23-112 and # 23-113. These are left- and right-hand brakes with parking brake mechanisms that are rated for a 6K axle system. You can use lock washer # 38LW and nut # 38N to install the brakes. If you need a brake adjustment tool we offer part # W80630.

  • Recommended Axle-Less Suspension And Surge Brakes With Parking Brakes
  • The Timbren axle-less system I recommend is part # TASR5200S03. This system has a 4-inch lift spindle and includes the brake flange. The hub and drum assembly you can use is part # 8-201-5UC3-EZ. This is a 6 on 5-1/2 hub and it has the E-Z Lube feature that makes it easy to keep the bearings lubed. This system includes the bearings, races, seal, lug nuts and grease cap. The brakes I recommend are part # T4203000 for the right hand and part # T4203100-000 for the left hand. These...

  • Suspension Enhancement Recommendation for a 2011 Dodge Ram 1500 Towing a Gooseneck Trailer
  • For occasional towing with your 2011 Dodge Ram 1500, I would go with the Timbren suspension enhancement system. If you do not have a Quad Cab, use # TDR1500DS. If you do have a Quad Cab, use # TDR1500DQ (instructions linked for reference). The Firestone systems are good when you carrying varying sized loads and have to adjust the ride accordingly. But for occasional towing of the same trailer, the Timbren system would be the way to go.

  • Rear Suspension Enhancement Options for a 2004 Cadillac Escalade EXT
  • I may have a solution that will work for you, however, we do not offer replacement air shocks for your 2004 Cadillac Escalade EXT at this time. We do offer coil spring air bag inserts like the AirLift 1000 Air Helper Springs, # AL60769. These air bags fit in the rear coil springs and can be manually inflated for additional support. Another option would be a bump stop replacement like the Timbren Rear Suspension Enhancement System, # TGMRG25C, that you referenced. These are rubber springs...

  • Recommended Compatible Hubs for Use with Timbren Off-Road Suspension System ASR35HDS02
  • In order to use 6-on-5-1/2-inch bolt pattern hubs on a Timbren axle-less suspension system those hubs will have to use the same bearing set as the hubs intended for that system. In the Timbren system # ASR35HDS02, for example, which has 4-inches of lift and is rated for 3500-lbs and off-road tires, the bearing set is inner bearing # 25580 and outer bearing # 15123. We do offer idler hubs and hub/drums in the 6-on-5-1/2-inch bolt pattern that you can see by clicking on the link provided....

  • Rear Axle Suspension Kit Recommendation for 2013 Ram 1500 Quad Cab with Coil Springs
  • The Timbren rear axle jounce spring kit you referenced, part # TDR1500DQ, is a fit for your 2013 Ram 1500 Quad Cab. This rear axle kit fits both 2WD and 4WD models. There are several types of rear axle kits available for your Ram 1500. These include rubber jounce springs like the Timbrens, air bag kits from AirLift and Firestone, and coil springs such as the SuperSprings Sumo urethane coil helper springs.

  • Timbren Axle-Less Trailer Suspension System Recommendation for a 1977 13 ft Scamp Trailer
  • Converting a torsion axle trailer to a trailer with a Timbren Axle-Less Trailer Suspension System has been done before and most people who have done this really prefer the smoother ride and increased ground clearance. Timbren Axle-Less trailer suspension system is a great alternative to torsion axles. While both systems allow either side of the trailer's suspension to operate independently, only Axle-Less suspensions are actually separate units. Torsion axles still require a bar that...

  • Reducing Rear End Squat when Towing Trailer with 2014 Ram 1500 Crew Cab 2x4
  • Normally weight distribution is the best option when squat is caused by a coupled trailer. But since the manufacturer of the trailer specifically said not to use it the next best option would be suspension enhancement for your 2014 Ram 1500. I do recommend the Timbren springs # TDR1500DQ because they do work well. They may allow the suspension to travel some before they engage but the squat should be reduced if not eliminated. I have included a link to a video showing installation of...

  • Tips for Reducing Sway When Towing Ice Castle Fish House RV Trailer
  • I looked up pictures of the coupler setup of your trailer and it would not be compatible with a weight distribution system since it basically uses a pole tongue and has a pipe that runs on top of the pole tongue as well. What you can do to fight sway is make sure that you have the trailer setting as level as possible when you are towing. (See help article on how to pick out the correct ball mount to allow this). Most sway is due to not having enough tongue weight relative to the...

  • Off Road Axle Recommendation for Trailer for 8 on 6-1/2 inch Bolt Pattern Hub
  • The Timbren Heavy-Duty Axle-Less Trailer Suspension # ASR35HDS02 will be perfect for you. It's got a 4 inch lift built into it and is set up for wider tires so it's ideal for off-road applications. And then for a hub with the 8 lug pattern that you need you would want the part # 42865-KIT that you referenced.

  • Recommended Timbren Axle-Less Trailer Suspension for 5 on 5 inch Jeep Wrangler Tire
  • The Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange # ASR2000S02 does have the ability to incorporate a hub that has a 5 on 5 bolt pattern. If you would like just the hub it is part # AKIHUB-550-35-K and if you would like to have brakes you will need the Hub and Drum # AKHD-550-35-EZ-K, Right Hand (passenger's side) Brake Assembly # 23-48, and Left Hand (driver's side) Brake Assembly # 23-47. With that being said, we highly recommend using trailer tires on a trailer...

  • How to Decrease Sag on 2016 Ram 1500 When Towing
  • A Timbren Rear Suspension Enhancement System is a great way to reduce sag on your 2016 Ram 1500. They're easy to install without any drilling by replacing the factory bump stop. If your Ram is a Regular Cab, you will need # TDR1500DS. If you have the Crew or Quad cab, then you'll need # TDR1500DQ. I've included an installation video on a 2014 Ram which is a very similar process to yours. The best way to reduce sag is with a weight distribution system. A weight distribution system...

  • Recommended Hub/Drum and Idler Hub for Timbren Axle-Less Suspension # ASR35HDS02
  • For a brake drum hub, Timbren recommends the # 8-201-9UC3-EZ from Dexter Axle, which features a 6 on 5-1/2 bolt circle. For an idler hub, go with the # 42655UC1-EZ. Both hubs use the # 25580 inner and # 15123 outer bearing, which is compatible with the spindle used by the Timbren # ASR35HDS02 axle-less suspension you referred to. If you go with the hub/drum, you'll also need a brake assembly. I'd recommend going with a Nev-R-Adjust assembly, like # 23-459 for the right side and #...

  • Electric Trailer Brakes and Hub/Drum Assemblies for Timbren Axle-Less Suspension Kit
  • If you have a 2K-rated Timbren axle-less suspension kit # ASR2KHDS03, which includes brake flanges but not hub/drums, you can add brakes and hub/drum assemblies. For the hub use part # 84546UC3-EZ. This has the matching bearings and 5-on-4-1/2 wheel bolt pattern. For compatible self-adjusting 10-inch electric drum brakes use kit # AKEBRK-35-SA, which is a pair of left- and right-hand brakes rated for 3500-lbs.

  • Hubs, Brake Assemblies and Brake Controller to Use with Timbren Axle Less System ASR2KHDS03
  • The Timbren Axle Less System part # ASR2KHDS03 that you referenced will weld or bolt on to the trailer frame. Hardware for that is not provided. For hub/drums to fit the included spindles you would want the part # 84546UC3-EZ and then for brake assemblies you would want the part # 23-27 for the right hand side and part # 23-26 for the left hand side. The hubs are for a 5 on 4-1/2 inch bolt pattern. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885....

  • Hub/Drum Recommendation with 8 on 6.5 Bolt Pattern for Use with Timbren Axle Less ASR35HDS02
  • For a hub/drum that fits the Timbren Kit part # ASR35HDS02 and will give you an 8 on 6-1/2 inch bolt pattern we have the part # 8-219-4UC3-EZ which will work well. These are sold individually so you need a quantity of 4 of these. These are EZ lube hubs. For brake assemblies you need 2 of the # AKEBRK-7R-SA for the right hand side and 2 of the # AKEBRK-7L-SA for the left hand side.

  • Methods of Improving Sway Control on 31 Foot Rockwood Camper towed Behind Ford F-150
  • The Timbren Rear Suspension Enhancement System you mentioned, # TFR1502D is primarily designed to suspend the load of cargo stored in the bed of your truck, and will not have much if any effect on trailer sway. First and foremost, if the trailer has insufficient tongue weight, it will be more susceptible to sway. The tongue weight of the trailer should be at least 10 percent of the weight of the trailer. If it is less, try moving some of the gear stowed in the trailer forward of the...

  • Is the Timbren Axle-Less Trailer Suspension System a Good Choice for a Motorcycle Trailer
  • The Timbren suspension system, like # A20RS440, is designed to be toe-in when there is no load on it. So when the load is placed on it it will push the tire out so that it is riding straight on the ground. Provided the trailer is not overloaded and the tires are trailer tires and inflated to the maximum psi as indicated on the tire, then you should not see excessive wear and get more than just a few thousand miles out of a set. A regular axle has a bow in it. That bow should be pointed...

  • Suspension Enhancement or Weight Distribution for 2012 Dodge Grand Caravan Towing 21 ft Camper
  • The Timbren Rear Suspension Enhancement System you mention is primarily meant to suspend weight carried in the cargo area of the vehicle itself, but it would not necessarily be the best choice to act against the sag caused when the trailer is hitched to the vehicle. While the tongue weight does compress the rear suspension of the vehicle, it also unloads the front suspension which will reduce braking and steering performance. As you can see from the video I have linked you to, the Timbren...

  • Recommended Axle-less Trailer Suspension To Replace Tandem Torsion Axles
  • We don't carry the complete torsion axle you are looking for, however, I recommend the Timbren Heavy-Duty Axle-Less Trailer Suspension - 4" Lift Spindle - Wide Tires - 2,000 lbs # ASR2KHDS03 that will fit your trailer and will also give you more clearance underneath your trailer. It uses just a 2 inch square tubing between the axles and gives you the suspension you need in the axle-less suspension. This axle-less system can be used for tandem applications.

  • Timbren Suspension Kit Recommendation for 2016 Ford F-150 4x4
  • Both of the kits you mentioned are a fit for your 2016 Ford F-150. The difference is that the part # TFR1504E has a 6,000 lb capacity and the part # TFRTT1504E has a 7,000 lb capacity. You would want to go with the lower rated spring as it will be a smoother ride quality. The higher capacity will be harsher. A 13 mm socket will be used to remove the bolt that holds your current bump stop in place. You basically will then need to use the attached diagram to assemble all of the Timbren...

  • Timbren Axle-Less Trailer Suspension for Off-Road Trailer Fabrication Project

Timbren kit # ASR2KHDS03 is rated for 2000-lbs and has spindles with 4-inches of lift. It is intended...
