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...

  • 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...

  • 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.

  • Comparing Timbren's and SumoSprings for a 2017 Chevy Silverado 3500
  • Yes, the Timbren Rear Suspension Enhancement System part # TGMRCK25D and the SumoSprings Solo Custom Helper Springs part # SSR-207-47 are confirmed to fit your 2017 Chevy Silverado 3500. Both products will help to reduce sag, improve stability, and increase the existing suspensions wear life. Generally speaking, Timbrens are going to give you more support but SumoSprings will have a smoother ride. Of these two options, I recommend using the Timbren's as these will be more inline with...

  • Comparing Timbren Helper Springs for a 2015 Chevy Silverado 3500
  • Timbren helper springs # TGMRCK25D and # TGMRTT35D have different designs. The springs for kit # TGMRCK25D are double-convoluted. For optimal balance between softness and toughness, fabricators choose the double-convoluted rubber spring. Taller than the single donuts, these springs are engineered to deliver superior ride quality and significant load capacity. The springs in kit # TGMRTT35D are single-convoluted. When space is limited or extra stability is required, fabricators and engineers...

  • Dimensions for the Springs in the Timbren Suspension Enhancement Kits for a 2013 Chevy 3500HD Diesel
  • Once installed, the double convoluted springs from the Timbren SES Kit, # TGMRCK25D, will sit 5-3/16 inches below the jounce bumper holder on the frame. The outer diameter of these springs is 4-5/16 inches. The single convoluted springs from the Timbren SES Kit, # TGMRTT35D, are only 3-9/16 inches tall, but this kit also includes a 1 inch spacer, so it will sit 4-9/16 inches below the jounce bumper holder on the frame (see photos). The outer diameter of these springs is 4-1/4 inches.

  • Suspension Enhancement Recommendation for 2016 GMC Sierra 3500 for Smoother Ride Unloaded
  • We have found that the Timbren setups affect the unloaded ride quality of a vehicle more than the other suspension enhancement solutions. For a similar solution that we have found to be a bit less harsh the Firestone Work-Rite kit part # F8632 would be a great option.

  • Timbren Suspension Enhancement for the Front and Rear Axles of a 2015 Chevy Silverado 4WD
  • The Timbren System part # TGMFK25D that you referenced is just for the front axle of your 2015 Chevy Silverado 2500. Each side of the front axle takes 2 of the rubber springs. For the rear axle you would want the # TGMRCK25D as well.

  • Can Spacers be Added to Timbren Helper Springs for a Lifted 2012 Chevy Silverado
  • Timbren does have spacers, # A25723-90AH00, that you could use. You would need a total of 4 of them since each is 1 inch tall and because you have a 2 inch lift. I have included a couple of video links for you. One is an installation of kit # TGMRCK25D. The other is an installation that uses the spacers.

  • Which Timbren Suspension Kit Fits Rear Axle of 2015 Chevy Silverado 2500HD
  • The part # TGMFK25D can only be used on the front axle of a vehicle. It is a fit for your vehicle though but you would need all 4 pieces. For rear Timbrens confirmed as a fit for your 2015 Chevy Silverado 2500HD we have the # TGMRCK25D which would be what you need. I attached an install video for this kit for you to check out as well.

  • Recommended Rear Axle Suspension Kit for 2015 GMC Sierra 2500 Towing Trailers
  • The type of rear axle suspension enhancement kit that will do what you're looking for - provide support when your suspension is under load from the trailer, but not otherwise change anything in terms of ride quality - is a Timbren jounce spring kit. Timbren kit # TGMRCK25D that you referenced will do this while offering an easier installation than almost all other kits. The Timbrens provide progressive resistance as the load increases. It is also a zero-maintenance item that you can...

  • Recommended Timbren Suspension Enhancement For Slide In Camper On 2016 Chevrolet 3500 4WD
  • I definitely recommend the Timbren springs over the Stableloads. I reached out to my contact at Timbren about the differences between the rear suspension models for your 2016 Chevrolet 3500 4WD and he said that the Timbren Rear Suspension Enhancement System # TGMRTT35D are definitely what you want for your Lance 950s application. He said that these rear springs are made specifically for slide in campers. They are designed to have more coverage than the # TGMRCK25D, and even though they...

  • Can Timbren Front Axle Helper Springs be Used with Torsion Keys on a 2013 Chevy Silverado 2500HD
  • The Timbren springs # TGMFK25D for your 2013 Chevy Silverado 2500HD fit in place of the factory bump stops at the front of the truck. Provided the torsion keys you are using are not in this same area then the 2 products can be used together. I have included a link to the installation instructions and a video review to the right that should clarify the installation location.

  • Adding Trailer Brakes to a Timbren Axle-Less Trailer Suspension System
  • Yes, it is possible to add brakes Timren Axel-Less Trailer Suspension System. The Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/Flange - Off-Road Tires - 2.2K, # ASR1THDS03, that you were looking at has the brake flange mounted, so it is ready to add brake assembly and hubs to.

  • 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...

  • 2015 Ford F-150 Sags at the Back When Coupled to Trailer with 550 Pounds Tongue Weight
  • Sag at the rear of a vehicle such as your 2015 Ford F-150 can happen from 1 of 2 ways. First, weight in the actual truck bed can cause sag. Second, the tongue weight from a coupled trailer can cause sag. The ways to deal with the sag are different. When sag is caused by a trailer the recommended solution is weight distribution, not helper springs. Weight distribution will more evenly distribution the force of the tongue weight to all of the axles on the tow vehicle and trailer so it...

  • Replacement Axle Recommendation For Small Popup Camper

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...

  • 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...

  • 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...

  • 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....

  • 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...

  • 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.

  • Hub Recommendation for Timbren Axle-Less System ASR1THDS03 with Jeep Bolt Pattern
  • Typically the Jeep wheel bolt pattern is 5 on 5 inch. For an idler hub that will fit the spindles of the part # ASR1THDS03 and have the correct bolt pattern we have the # AKIHUB-550-35-K. This is a 3,500 lb trailer hub. The # ASR1THDS03 has a 4 inch lift built into it so it would work well for you since your Jeep is also lifted.

  • 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...
