Expert Answers about Timbren

  • 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...

  • 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.

To confirm your fit, we have two sets of jounce springs available from Timbren that are confirmed to fit your 2017 Ford F-350 Super Duty.

  • 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...

  • 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.

  • 2005 Ford Excursion Squats when Using Husky Weight Distribution with 9,000 Pound Trailer
  • Let's first look at the numbers. A trailer weighing 9,000 pounds will have a tongue weight in the neighborhood of 900 to 1,350 pounds. But when you calculate tongue weight for weight distribution you also have to factory in the weight of any cargo loaded behind the rear axle of your 2005 Ford Excursion. So for example if your trailer's tongue weight is 1,100 pounds and you have 200 pounds of cargo behind the rear axle of the Excursion the total tongue weight would be 1,300 pounds and...

  • Height of Timbren Helper Springs for a 2017 Ford F-250
  • There are actually just 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. So each of those part numbers appears twice because of the 2-wheel drive and 4-wheel drive categories. The springs in kit # TFR250SDJ are 4-1/2 inches tall and for kit # TFRTT350J they are 3-9/16 inches tall....

  • Timbren Helper Spring Recommendations for a 2017 Ram 3500 4x4 Diesel Short Bed
  • I will be happy to help with some rear helper springs for your 2017 Ram 3500 4x4 diesel short bed. First, for your application (towing a 5th wheel trailer) I do recommend going with Timbren springs rather than air bags since Timbren springs do not require maintenance or for you to add/remove air from air bags. But air bags are superior in other ways including having the ability to level the bed side to side and adjust the ride quality to be more or less stiff. For Timbren springs that...

  • Will the Timbren Silent Ride Suspension System Work with I-Beam Trailer Frames
  • The Timbren Silent Ride Suspension System will not bolt directly onto an i-beam trailer frame. However, as you mentioned, you can absolutely weld a solid plate to the inside of the i-beam frame where the frame brackets sit which will allow the system to work for you. I called Timbren and was able to confirm this. I highly recommend you have a quality and experienced welder perform this task. If you have 2-3/8" diameter trailer axles then you will want to use part # TSR7000T04 but if you...

  • Comparing Timbren Rear Helper Springs for a 2016 Toyota Tacoma 4x4
  • The springs in both Timbren kits for a 2016 Toyota Tacoma 4x4, # TABSOSR, and # TTORTUN4L, are both 3-3/4 inches tall. The difference is that kit # TABSOSR is intended for vehicles without a U-Bolt Flip Kit. And # TTORTUN4L is designed for vehicles with 3 Leaf Springs in the rear suspension. To avoid a stiff ride a better option would be air bags, # F2407. They will allow you to adjust the air pressure in the bags for the best ride quality. I have linked a video review of the Firestone...

  • Comparing the Timbren and Air Lift Suspension Enhancement Kits for a 2008 Toyota Sienna
  • Both the Timbren Rear Suspension Enhancement # TTORSEN04 and the Air Lift 1000 Helper Springs # AL60732 work in conjunction with the rear coil springs of your 2008 Toyota Sienna van. The Timbren system uses 2 Aeon hollow rubber springs that fit inside the Sienna's coil spring. The rubber spring provides additional support by increasing resistance between the upper rubber spring and the lower mount that is attached to rear axle. So, when weight is added to the rear of the van, the Timbren...

  • How Much Travel Distance Is Recommended for Fender Clearance with Timbren Axle-less Suspension?
  • You can absolutely use Timbren Axle-Less Trailer Suspension System on a custom trailer application, however the instructions state that the axle-less systems are not recommended for triple applications. With whatever system you end up using, you will want to leave a minimum of 4-7/8 inches of clearance above the tires for the suspension travel. If you end up using these axles, I recommend the Trailer Hub/Drum Assembly - 5,200-lb to 7,000-lb E-Z Lube Axles - 12" - 8 on 6-1/2 - Galvanized,...

  • Fit and Compatibility of Timbren Rear Suspension Enhancement on a 2015 Ram 5500 Cab and Chassis
  • I confirmed with Timbren that the # TDR5500 is indeed the correct suspension enhancement spring for your 2015 Ram 5500 Cab and Chassis. The contents of the kit are designed for the stop over the axle as seen in the attached diagram. This kit includes 2 aeon rubber springs. The # TDR5500 can be installed whether you vehicle was equipped with or without factory top overload springs. What it sounds like you are describing is the upper overload springs. The Torklift # TLA7200 is a good...

  • Recommended Timbren Rear Suspension Enhancement for a 2010 Toyota Tacoma With 4WD
  • There are a few different options that we have for you to install a Timbren Rear Suspension Enhancement System on your 2010 Toyota Tacoma that is 4WD. Please keep in mind that any suspension enhancement system will not increase your weight capacity. It is meant to supplement a suspension system that is in good working order. You should never exceed the weight-carrying capacity of your vehicle. If you plan on driving places that might not have a road then I recommend going with the Timbren...

  • Recommended Trailer Suspension Upgrade On 2016 StarCraft 24 RLS
  • For a suspension upgrade on your 1216 StarCraft 24 RLS, I recommend the Timbren Silent Ride Suspension for Tandem Axle Trailers w/ 2-1/2" Round Axles - 7,000 lbs # TSR7000T06. This system replaces leaf spring suspension to provide a stable ride distributing weight evenly between both axles. Rubber springs absorb road shock. This installation requires a 2 inch by 4 inch hollow steel crossmember with 3/16 inch thickness that is not included. If you have 3 inch axles, you will want #...

  • Advice on Towing a Fifth Wheel Trailer With a Short Bed 2017 Ram 2500 With Rambox
  • Thank you for your thoughtful question; let's start with the suspension components for your 2017 Ram 2500 first. I recommend using the Firestone Ride-Rite Air Helper Springs # F2598 over Timbrens for your application. The Ride-Rite air bags have the advantage of being able to adjust individually to guarantee you even load distribution, and are going to be less rigid than the Timbrens. As far as a fifth wheel hitch, you are going to have to use a Sidewinder because you have a Rambox...

  • Will Timbren Helper Springs Cushion Ride of 2018 Chevy Colorado when Towing with Weight Distribution
  • It is possible that the weight distribution system you are using is rated too high for the total tongue weight of the trailer. Total tongue weight is the tongue weight of the trailer when loaded and ready to tow plus the weight of anything loaded behind the rear axle in your 2018 Chevy Colorado. So for example if the trailer tongue weight is 500 pounds and you have 40 pounds of stuff behind the rear axle the total tongue weight would be 540 pounds. The 750 pound Blue Ox systems are rated...

  • Rear Helper Springs for a 2012 Ford F-150 4x4 and Forest River Stealth Model 1913
  • Timbren rear helper springs # TFR1504D for your 2012 Ford F-150 4x4 will definitely help with the sag you are experiencing when towing your Stealth toy hauler. But when not towing or carrying a load in the truck bed you will likely experience a stiffer ride, more jarring on bumps than the stock suspension. For a similar option that features a softer spring style we have SumoSprings # SSR-117-40 rated at 1,000 pounds, or # SSR-117-47 rated at 1,500 pounds. These springs will have more...

Timbren is a little more well-known but we have received feedback from our customers that the SumoSprings offer better ride quality as they aren't as stiff. If you are comparing the rear Timbren # TFRF53A with the rear SuperSprings # SSA41 for the leaf springs then they are comparable when it comes to performance but they work slightly...

These hubs are compatible with the spindles on the Timbren system and their 5 on 4-3/4 inch bolt pattern will fit your existing wheels. Then for hydraulic brake assemblies that will work with these hubs I recommend the etrailer.com # AKUBRK-35R for the Right Side and # AKFBBRK-35L for the Left Side. These particular assemblies...

  • How to Choose the Correct Timbren Rear Suspension Enhancement for a 2012 Ram 1500
  • The Timbren Rear Suspension Enhancement part # TDR1500DQ is an excellent option for your 2012 Ram 1500 as long it is not a regular cab. If you do have a regular cab then you will want to use the Timbren Rear Suspension Enhancement System part # TDR1500DS. The higher the weight capacity the spring is rated for, the stiffer the spring will be. A softer spring will result in a better ride quality but a stronger spring will give you more support. For your 10,000 lb car trailer, I recommend...

  • Recommended Timbren Springs to Help Bottoming Out in 2007 Nissan Xterra
  • For your 2007 Nissan Xterra I recommend going with the Timbren Active Off-Road Bumpstops # TABSJRC01 that you referenced. These are really designed for exactly what you're needing them for on your Xterra. They will replace your factory bumpstops and while they won't completely prevent you for bottoming out (no suspension enhancement system will), they are specifically designed to cushion the impact when it does happen so you don't experience that spine-crushing jolt. I actually also called...

  • Comparing the Timbren Rear Suspension Enhancements and Air Lift AirCell Custom Helper Springs
  • The main difference between the Air Lift AirCell Custom Helper Springs Kit part # AL52205 and the Timbren Rear Suspension Enhancement System part # TDR1500DQ is the hardness of material. The Timbren's are made of a much harder material than the AirCell's. This means that the Timbren's will provide more support but they may also have a rougher ride. Please note that the quality of the ride would only be affected while loaded. I personally like the Timbren's better and they have a much...

  • Hello, I will be happy to help you select some helper springs to improve the ride and level out the truck when you are towing. Timbren springs are an easy install but they will make the ride stiffer when you are not towing. The similar SumoSprings Solo # SSR-207-47 will also level out the truck but will not be as stiff when not towing compared to the Timbren springs. Another option to consider is Roadmaster Active Suspension # RAS3611-HD. Installation is easy with this kit as...

  • Suspension Enhancement Recommendation for 2018 Mercedes-Benz Sprinter 3500 Motorhome
  • For your motorhome built on a 2018 Mercedes-Benz Sprinter 3500 we have great suspension enhancement kits available but none that use air bags. Instead the kit I would recommend is the SumoSprings kit part # SSF-106-47 which is similar to the Timbren but won't be as harsh of a ride. This will help brace the rear suspension which will help the vehicle ride better and not have quite as much body roll. If you haven't driven the motorhome yet I'd recommend doing so first. There's no rule...

  • Should 3,500 lb or 5,200 lb Timbren Axle-Less System be Used for over 3,600 lbs of Loaded Trailer
  • Since your axle will ultimately be under the weight of your trailer and it's contents you definitely need to make sure that it is rated for more than what you will be carrying. You need to go with the 5,200 lb weight capacity. For this we have the Straight Spindle # ASR5200S01, 4" Lift Spindle # TASR5200S03, and 4" Drop Spindle # ASR5200S04. This is compatible with the idler hub # 8-213-5UC1-EZ or the hub and drum assembly # 8-201-5UC3-EZ. I recommend going with the hub and drum assembly...

  • The difference in harshness between the Timbren kits part # TFR350SDF and # TFRTT350F would be very noticeable. Especially when unloaded. Your truck is already going to have a rough ride as that is the nature of 1 ton trucks but the 12k Timbren kit will make for a very harsh ride when unloaded. I really wouldn't recommend that unless the truck is going to be loaded to near it's max capacity most of the time it will be on the road. For what you are looking to do I would go with the lower...

If you want to upgrade from your 3,500 lb axles to larger capacity axles, you can use the Timbren Silent Ride Suspension for Tandem Axle Trailers w/ 3" Round Axles - 14,000 lbs # TSR14KT01 but you will want to make sure your other trailer components can handle that additional capacity. You will be limited by the weakest component of your entire system. If you just want to keep...
