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...

  • How to Reduce Sway in 2016 Ram 2500 Diesel Laramie Crew Cab with a Truck Bed Slide-On Camper
  • Congratulations on your new truck bed camper! I'm sure you will enjoy it for many years. Sway is a common issue with truck bed campers which can be reduced, but not eliminated. The campers are not particularly aerodynamic and the sway will increase with your speed and high winds. Even though your truck sits level with the camper installed, you could still benefit from a Suspension Enhancement System (SES). I recommend a jounce-style spring system like the Timbren # TDR2500D. These install...

  • Recommended Trailer Axle Kit for Fabricating Off-Road Utility Trailer
  • If you are building your own firewood hauling trailer you might want to consider one of our Timbren axle-less suspension kits. These are available with idler hubs and some also have lifted spindles that can give you better ground clearance (for use in the woods when gathering your firewood). We do have standard beam axle kits too but the Timbrens can be the ideal way to go for fabricators that want an effective but simple installation of their trailer suspension. The linked page will...

  • What would I Need to Upgrade from 3,500 lbs Tandem Axles to 5,000 lbs Tandem Axles
  • We carry the Timbren Axle-Less System rated at 5,200 lbs part # ASR5200S01. The axle-less system mounts to your trailer frame and takes the place of your old axle and springs.# ASR5200S01 is a straight spindle design. Timbren also offers these axles with a 4 inch drop spindle part # ASR5200S04. The Timbren Axle-Less can be mount tandem to repalce your tandem axles. There is no need to install leaf springs, because the Timbren axles have built-in spring system on each axle. However,...

  • Rear Helper Spring Recommendations for a 2016 Ram 3500 with Factory 5th Wheel Prep Package
  • First, Timbren rear helper springs # TDR3500CA will bolt on to the bottoms of the frame on your 2016 Ram 3500 and will not interfere with the factory 5th wheel prep package. The Timbren springs will help with sagging when the truck is loaded/towing and take the strain off of the factory suspension. The ride can be more stiff when the Timbren springs are engaged. For a system that you can adjust to get the ride quality and support to your liking I recommend air bags such as Firestone...

  • Measurements for Timbren Silent Ride 14K Suspension System
  • This particular model of the Silent Ride suspension, # TSR14KT01, is rated for 14,000 pounds and has a 3 inch round axle seat. I have included a picture that shows all of the important measurements for this unit for you as well. Current pricing is available on the product page.

  • 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...

  • 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 Axles For Low Deck Height On Trailer Build
  • We do carry axles and I've linked the page to all of your options. For a low deck height, I recommend using the Timbren Heavy-Duty Axle-Less Trailer Suspension - 4" Drop Spindle - Regular Tires - 2,000 lbs # ASR2KHDS05 or the 3,500 lb 4 inch drop spindles with drum brakes # ASR2KHDS05. The 4 inch drop will give you a lower deck height than a standard axle and will also give you increased ground clearance by using the integrated suspension and smaller crossbar of 2 inches square if...

  • We do have engineering diagrams for the Timbren Axle-Less Trailer Suspension System # A35RD545E that you referenced, and we do show these on our product page. If you scroll down a bit you'll find several measured drawings of this system with dimensions and mounting points. I have also linked one of these images for your review. This kit installs either by welding or bolting to your trailer frame and two sets can be used for a tandem-type application (but not three). Included are built-in...

  • What Stops Porpoising on Tow Vehicle that is Using Weight Distribution with Trailer
  • Most of the time when a tow setup is porpoising with a weight distribution system all you have to do is add a bit more spring bar tension to minimize the porpoising. With an Equalizer system you would need to angle the spring bars down further to add the additional tension. Suspension enhancement like the Timbren part # TGMRCK15S would help but you should be able to solve the problem with the WD system.

  • Will Timbren Axle-Less System Allow Lower Deck Height on Trailer?
  • There is a Timbren Axle-Less Suspension System which will allow you to lower your deck height, though it won't give you quite the amount you are looking for. The Timbren # A35RD545E has a 4 inch drop spindle so it will lower your deck height by that much. This system comes with electric brakes and hubs with a 5 on 4-1/2 bolt pattern. You would be able to use a wheel and tire combination such as the Taskmaster # AC14R45SM which have 14 inch wheels and a total diameter of 26.1 inches. I've...

  • What is the Towing Capacity of a 2007 Ford F-150
  • The maximum towing capacity of your 2007 Ford F-150 will vary depending on cab, wheel size, drive type, engine size, and rear axle ratio. Therefore, the only true way to tell what your trucks towing capacity is would be to find both the Gross Combined Weight Rating (GCWR) and the Gross Vehicle Weight (GVW). These figures can be located on the information tag inside the drivers door jamb. If you subtract the GVW from the GCWR, that will give you the maximum gross trailer weight (GTW) you...

  • 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...

  • Comparing The Timbren Axle-Less Trailer Suspension System To The FlexiRide Half Torsion Axle System
  • For an off road overland trailer, I recommend you go with the Timbren Axle-Less Trailer Suspension System with Hubs - 5 on 4-1/2 - Off-Road Tires - 1,200 lbs # A12WS545 and not just because we carry them...as I know seems like a conflict of interest. The Flexiride system even with a 1,400 lb capacity is not made for off road and the suspension is a torsion system with rubber cartridge on each side. The Timbren system uses more of a jounce style bumper that the company is known for regarding...

  • Comparing Timbren Axle-Less Suspension for Standard Tires and Wide Tire Applications
  • The Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange - Regular Tires - 2,000 lbs # ASR2000S02 is a suspension system integrated into a spindle that can use a 2 inch square bar to created an axle of whatever length needed. The Timbren Heavy-Duty Axle-Less Trailer Suspension - Straight Spindle - Wide Tires - 2,000 lbs # ASR2KHDS02 is basically the same system with a wider base prior to the brake flange and spindle to account for a wider tire. It will give you 8-1/2 inches...

  • 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. The link provided will take you to our page showing all of these products. The...

  • 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...

  • 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...

  • Converting Military Surplus M101A3 Trailer Surge Brakes to Electric or EOH Brakes
  • It is possible to install electric trailer brakes or an electric-over-hydraulic (EOH) braking system on a trailer that has surge brakes, like your M101A3 single-axle trailer. Installing electric drum brakes will be simpler and less costly that going with an EOH system. The linked articles explain the process for each option: electric, EOH drum and EOH discs. EOH disc brakes will give you the best stopping power but this option is also the most involved and carries the highest price tag....

  • Which Spindle Height of Timbren Axle-Less Trailer Suspension for Car Trailer
  • The drop spindle model you mentioned, part # A35RD545E would be used over the straight spindle model, part # A35RS545E if you wanted a lower deck height on your car trailer. Since you are most likely already using ramps, I cannot see how you would benefit from further lowering the trailer deck height. The straight spindle model would place your spindle center about 4 inches below the mounting surface of the unloaded trailer. The drop spindle model would place the spindle center about 1/4...

  • Can a 2008 Chevy Silverado 2500HD Tow a 16,500 Pound 5th Wheel Trailer
  • The GVWR of a vehicle is set in stone. There is nothing you can do to increase the capacity short of replacing the axle, suspension, and other load bearing and drive train components. What suspension enhancement like # TGMRCK25S does is help support the load and keep the rear end from sagging. Since you have a 3/4 ton truck, you are going to be able to tow just about anything. Consult the vehicle owners manual for the towing capacities of the truck. The gross COMBINED vehicle weight...

  • Which Timbren Suspension Kit for 2017 Ford F-250
  • There are 2 Timbren helper spring kits for the 2017 Ford F-250. First we have # TFR250SDJ which has an 8,600 pound capacity and fits 2- and 4-wheel drive models. And second we have # TFRTT350J which is rated for 8,000 pounds and also fits 2- and 4-wheel drive models. The higher weight capacity and the fact it's not as popular as the lower rated kit is why there is a price difference. I prefer to recommend the lower capacity kit as it will give you a smoother unloaded ride quality.

  • 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.

  • I can get you a hub assembly that fits, but the Idler Hub Assembly # 84655UC1-EZ will NOT work with the Timbren Heavy-Duty Axle-Less Trailer Suspension # TASR35HDS06. Instead, you're going to need a hub and drum assembly with this suspension and the correct fit is Hub and Drum Assembly # AKHD-655-6-EZ-K. This assembly is compatible with the Timbren's EZ Lube spindle and uses the correct inner bearing # 25580, outer bearing # 15123 and grease seal # GS-2250DL

  • What Type of Tires to Use on Home-Built Off-Road Trailer
  • The term regular tires when used in the context of Timbren axle-less suspension systems like # A20RS545 distinguishes this kit from one that can be used with off-road trailer wheels/tires, such as kit # ASR1THDS03. Do please note that for a fabricated trailer you will want to use only trailer wheels and special trailer tires. Passenger vehicle wheels and tires are built differently and are not suitable for use on a trailer. Trailer wheels usually have different offset (the distance they...

As long as the mobile home trailer does not exceed your max tow rating, yes you can safely tow the 32' trailer. Depending on how frequently you will be towing the mobile home, I recommend the use of either suspension enhancements or a weight distribution system. If you will be frequently towing this trailer,...

The lighter duty SumoSprings is what I recommended as it will still give support but it would have a minimal affect on ride harshness. There a guy that works here who has had both installed on his truck and he...
