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...

  • 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,...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • Recommendation to Upgrade Axle and Hubs on Northern Hardware Trailer
  • To upgrade the axle and hubs on your Northern Hardware Trailer, I recommend looking at an Axle-Less System like the Timbren # A20RS545. This suspension system will provide you with a smooth, quiet, and safe ride and can completely eliminate the need for an axle. It is designed to fit any frame width and features straight, EZ Lube spindles for easy bearing lubrication. This particular system is rated for 2,000 pounds and includes idler hubs with a 5 on 4-1/2 inch bolt pattern. They will...

  • 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...

  • 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...

  • 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...

  • Replacing 3500-lb Axles with 5200-lb Axles on Enclosed Cargo Trailer
  • You can change out the 3500-lb axles on your enclosed trailer with higher-capacity 5200-lb axles but this will not necessarily increase the weight capacity of the trailer. The trailer manufacturer should be consulted (giving them your trailer's VIN) to allow them to determine if the other components in it, such as its frame, have the capacity to allow you to benefit from increasing the axle rating. Also, it will likely be necessary to change your hubs to ones that are higher rated to...

  • Recommended Timbren 3,500 Axle-Less System with 4 Inch Lift Spindle for Lance Trailer
  • The only real difference between the Timbren Heavy-Duty Axle-Less Trailer Suspension with 4" Lift Spindle - 3,500 # ASR35HDS05 and the standard Timbren # ASR3500S06 is that the Heavy-Duty model features a larger spindle that would accommodate larger hubs and wheels. I am not sure why Timbren would have suggested the Heavy-Duty model for your application but the standard Timbren # ASR3500S06 features the capacity you need, the lift you are wanting, and would allow you to retain the use...

  • 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.

  • What Is The Tow Capacity Of A 2001 Chevrolet Suburban
  • The 2001 Chevrolet Suburban has a towing capacity ranging from 5,900 to 8,800 lbs depending on equipped features. You should consult your owner's manual for the exact specification. 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,...

  • Recommended Suspension Enhancement for 2016 Ford F-150 Crew Cab 4x4
  • The Timbren Suspension Enhancement System # TFRTT1504E is a confirmed fit for your truck. With a 1,100 lb tongue weight trailer, this system will help to keep the rear end from squat and your headlights from being too high to see the road as intended. These will act as a shock absorber as well as helping to stabilize your truck when under load. These spring are made for severe service vehicles like tow trucks so I don't recommend then for your truck as they can actually cause your truck...

  • 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...

  • 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...

  • Idler Hub Compatible With Timbren Axle-Less Suspension System
  • 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

  • Which Hubs Fit the Timbren Heavy-Duty Axle-Less Trailer Suspension # TASR35HDS06 with 2" Lift
  • The hubs that fit the Timbren Heavy-Duty Axle-Less Trailer Suspension # TASR35HDS06 use inner bearing # 25580, outer bearing # 15123, and a grease seal with a 2-1/4" inner diameter. For regular hub use part # AKIHUB-655-6-EZ-K but if you are wanting to incorporate brakes then you want hub and drum part # AKHD-655-6-EZ-K with the brakes # AKEBRK-7-SA for electric or # AKFBBRK-7 for hydraulic. I have attached some installation videos that you can reference as well.

  • 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.

  • Timbren or SumoSprings Recommendation for a 2015 Chevy Silverado 2500
  • Because the Timbrens like part # TGMRCK25D that you referenced have a reputation as having kind of a harsh unloaded ride quality I would recommend the SumoSprings part # SSR-207-47 since you will get the same support without as harsh of a ride when the vehicle is unloaded. I attached an FAQ on Timbrens for you to check out as well.

  • Removing Factory Suspension Bump Stops on 2011 Chevy Silverado to Install Timbren Rubber Springs
  • The bump stops are compression fit into the cups on the truck frame, therefore they aren't designed to come out easily. I have spoken with one of my contacts at Timbren, who tells me that the bump stop can be removed with a pair of channel lock-type pliers. Grasp the bump stop with the pliers and pull down on it while twisting back and forth. In case you do not have them handy, I have provided a link to the install instructions.

This is a 3,500 lb axle setup that has a 4 inch lift built into it and is spaced out for off-road tires. For an idler hub that fits it with a 6 on 5-1/2 inch bolt pattern we have the part # AKIHUB-655-6-K.

  • 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...

  • What is Recommended Distance between Timbren Spring and Axle
  • You will want to have the rubber spring of the Timbren part # TFR1502D sit close to the axle but not touching it when unloaded. There isn't an exact dimension for what will work best as people have different preferences and some vehicle suspensions move more in general. Timbren likes to recommend 1 inch between the axle and the Timbren when the truck is unloaded. We have found that this works the best.
