Reduced rear axle sag with Timbren suspension enhancement

Whether you're hauling heavy loads in your bed or cargo area or towing a trailer, you will often see the rear of your vehicle sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but also more of the vehicle's weight. Because less weight is on the front axle, the front tires are making less contact with the road. Overall handling - traction, steering, and braking - is negatively affected. But the resistance from Timbren's Suspension Enhancement System works with your factory suspension to keep your vehicle level and improve your driving experience.


Diagram of the Timbren spring installed

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above your rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the leaf spring sits, 1" above the axle. The inch of clearance allows the existing factory suspension to operate normally under light loads and standard terrain, ensuring the smooth, comfortable ride that you are used to.


Action of a standard Timbren rubber spring

Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape increases resistance, stiffening the suspension and keeping your vehicle level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's-side or passenger's-side of your vehicle. This is helpful when you swerve or make sharp turns. Each spring is activated when it is needed, so body roll is greatly reduced. The independent action also works well when you are hauling off-center loads.


Trailer swaying as it is towed behind a truck

Because your vehicle handles better with the springs, less turbulence will be passed along to the trailer and this helps to keep the trailer in line. Your driving comfort is further enhanced if the trailer does begin to sway (from a gust of wind or a passing semi) because the movement from the trailer is not transferred to your vehicle. This also works to make the sway subside more quickly.


An empty truck on a bumpy road without Timbren SES

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. Wear and tear on the factory suspension is also lessened because the rubber springs work to prevent bottoming out on rough roads.


Timbren Suspension Enhancement Compared to the Competition

Timbren's Suspension Enhancement Systems are much easier to install than air springs - there are no air hoses to run, no compressors or gauges to hook up, and no manual adjustments to make. The rubber construction makes Timbren's springs more elastic than similar products constructed of microcellular urethane. And more elasticity allows for a more comfortable ride because the rubber has more travel.

Video Transcript for Timbren Front and Rear Suspension Enhancement Systems Review

Speaker 1: Today we're going to be taking a look at the Timbren line of suspension enhancement systems. Any time that we add weight to our vehicle, it's going to put a lot of strain and stress on the suspension, especially if we're towing a heavy camper, trailer, or we have a heavy load in the back.Tends to have the back end squat down, which again, it's going to put that strain and stress on the rear suspension because not only are we asking it to hold up the weight of the vehicle, but everything else that we add on to it. Which that can arise a lot of different issues. The front end is going to be getting pulled off, which will misalign our headlights, and our tires won't have as much contact, so our steering and braking is going to be diminished.But tat;s where timbrens are going to come into play. They're going to provide us that extra support so that when we do have those heavy loads, the back end doesn't sag down quite as much, and it's not putting so much stress on the back end. By doing that, the front end's not going to rise up, which means our headlights will be in line and our tires will have the correct amount of contact and pressure, so our braking and steering isn't affected.

And they're going to do that all while making our ride more comfortable with that extra load.Our timbrens are going to provide us the support we need by replacing our factory jump stops and mounting in between the frame and the axle. Now, yours may look different, so you want to double check inaudible 00:01:20 fit guide for your specific application.Now, each one of our timbrens is going to feature a steel bracket. They're all going to have black, powder coat finish on them to resist that rust and corrosion or any other kind of chemicals that may be on the road. They're going to have a hollow, rubber ayon 00:01:36 spring that's going to take a lot of that pressure and strain off of the rear suspension.Whenever we do load our vehicle down, the space between our frame and our axle is going to get smaller. That's where our spring is going to make contact with the axle, and it's going to start compressing.

Now, they are progressively rated, so if we have a small load or a light load, it's going to have a little soft engagement. But the further it gets compressed, the harder and stiffer it becomes, giving us the support we need with those heavy loads.And since they are rubber, they're going to have a lot of give to them, which means they're going to give us the support we need. But at the same time, they're going to give us some more cushion and absorb some of the road shock as we drive. And since the rear ones here aren't in constant contact with our aXle, it is going to provide us the same ride quality when it's unloaded.Our timbrens are going to work independently from each other from side to side. That way, if we have an off center load, it will help compensate for that, but at the same time, if we take an evasive maneuver or a really sharp turn, this is going to help reduce that body roll and some of that sway feeling that we get going on when we have a lot of added weight.Our timbrens for the rear are going to be a good enhancement for any time you're going to be adding weight to the back of your vehicle, whether it be a heavy trailer, a large load in the back or any other situation where you're adding a lot of weight to the back of your vehicle.Now, timbrens on the front are going to be a little bit different.

They're going to provide us that load-leveling support and make sure the front end doesn't get pushed down too far. However, these typically are going to be in contact all the time, which means it's going to give us that support and help reduce on that body roll all the time, all while absorbing that road shock, giving us a smoother ride.Now, some situations where you'd want that extra support on the front of the vehicle to keep it from getting pushed down too much would be if you have a snow plow or winch, if you flat-tow your vehicle, or if you have any other heavy accessory on the front. This is going to make sure that front end stays where it should be, and again, making sure our tires, braking and steering acts how they should.When comparing the timbrens to other suspension enhancement options like airbags, these are going to be a lot easier to install because we're not going to have to worry about running lines, maintaining air pressure, putting in switches or compressors or any of that. Once these are installed, these are going to be completely maintenance free. However, airbags are going to provide us with a lot more adjustability, whereas our timbrens are not going to have that.That'll finish up your look at the timbrens suspension enhancement systems..

I purchased these to help with the squat on my F-150 when towing my 32--foot travel trailer. I need to tweak the setup on my WDH, but otherwise am very pleased. Without the trailer, you don't even know they're there. 558730

Ford F-150

I was towing my 32 ft travel trailer using standard WdH and sway bar with my f150 and before installing Timbrens, my truck was all over the place forcing me to grip the wheel (white knuckle) and stress out. After installing Timbrens, the rear of the truck feels planted while towing and I can literally tow now with one finger where before, I would have to give my steering wheel the death grip. Added bonus is that I can carry heavier loads in my bed if needed without squat. I can also pull my 32ft Trailer to the dump at State parks without WdH (saves bit of time) while driving slowly. I love the daily drivability and Ecoboost power of my f150 and now it's a towing machine! I'm a happy Timbren customer, as I didn't want to trade for a 250 and now I don't have to. 417589

This system worked out really well on my 2013 F150 XLT Crew Cab v8. I needed to remove the top rubber spacer, but afterwards, I have plenty of suspension travel for normal driving and good suspension control when towing. This reduced the "dolphining" I experienced while towing. Highly recommend this system for towing heavy loads. Also, recommend the Superchips programmer (towing tune) to round out your towing package. 722344

Ordered Sunday, received Friday. Love the service of etrailer and will continue to use them. Put the timbrens on my heavy 1/2T F150 and they went on like a charm. Used the spacer and got 1" of clearance, well within the requirements. This should take the sag out of towing my fifth wheel trailer. 525708

Item: TFR1502D: 2 wheel drive Ford F-150 I haven't used my truck to pull our camper yet ... but soon, weather permitting. The directions for installing this item on are terrible ... I had to make 3 calls to customer service on how to install and place the tabbed mounting bracket to the frame of my truck ... no one I talked to really knew. I see the picture as they are different, but wanted to be sure if I had done my install correctly. I recommend the video on U-Tube ... it has good information and the video will walk you thru the install. Please update the video on this product and include specifically how to assemble and place the brackets to the frame of your vehicle. Thank You 481346

After reading all the great reviews about how great this company is and how this product will level my truck with a heavy load, I ordered. I installed the product and the ride was an unbearably jarring. I emailed customer service with my concerns and let them know that I thought it would be fair to contact them prior to writing a review to try to come up with a solution. Wayne called me back and as we discussed the issues, it came down to him identifying four things that I consider non-solutions. 1. I cannot return the product. 2. He let me know that if I had more weight in my truck the ride would probably be better. 3. I could sell them on Craigslist. 4. I could add a set of air-bags. Airbags? These were suppose to be better than airbags. What a waste of money. 400179

I purchased the Timbren rear kit for my 2010 F150. I occasionally haul two motorcycles and wanted to get rid of the sag. The install could not be any easier. My truck required the extra bushings that are included, this gave me the recommended space between the axle and the bushing. Perfect fit, no issues. Great service from etrailer, ordered on sunday and package arrived Wednesday using the free shipping option. 7744

  • Suspension Enhancement Recommendation for 2014 Ford F-150 with 2 inch Drop
    We have suspension enhancement that is a fit for your 2014 Ford F-150 and is also designed for vehicles that have between a 2 inch and 6 inch drop like what you have, but there aren't any solutions from Timbren for that. Instead you'd want the Air Lift SlamAir kit part # AL59210. This gives you a way to provide additional suspension support that's adjustable.

  • Rear Suspension Enhancement for 2008 Ford F-150 to Reduce Suspension Sag When Towing
    The amount of tongue weight you have at 965 lbs it probably higher than what your F-150 is rated to tow which is why you are experiencing sag even with a weight distribution system. Suspension enhancement can help give you more support but if you are above the weight capacity of your vehicle suspension enhancement would not be enough to allow you to safely tow beyond that. The SumoSprings kit part # SSR-108-40 would give you an additional 1,000 lbs of support when towing though and...

  • Would Using an Air Bag System to Raise a Vehicle 1-1/2 Inches Cause Harsh Ride Quality
    If you want to raise the ride height of a vehicle by 1-1/2 inches you would have to use quite a bit of air pressure. Enough pressure to cause a much noticeable rougher ride. The best overall solution I could recommend for you would be to contact the lowering kit manufacturer you used and see why your truck dropped more than the kit was advertised for. You may have done something wrong or they sent you the wrong parts as typically lowering kits are not off by almost 1-1/2 inches.

  • Weight Distribution System Recommendation for a 2013 Ford F-150 Towing 8500 lb Trailer
    Actually for towing a trailer as heavy as yours I have a better solution than suspension enhancement. Instead you would want a weight distribution system. Not only will weight distribution help prevent rear suspension sag like the suspension enhancement, but it will also move part of the tongue weight of the trailer up to the front axle of the trailer which will help with braking and handling unlike suspension enhancement. The best way to pick out a weight distribution system is to base...

Second, the tongue weight from a coupled trailer can cause sag. The ways to deal with the sag are different.

  • Will the Timbren Suspension for the Ford F150 Affect Unloaded Ride Height

    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...

  • Selecting WD Hitch for Travel Trailer Towed by GMC Sierra 1500 Crew Cab
    We recommend towing a travel trailer with a weight distribution hitch (WDH) when the trailer weighs more than half of the tow vehicle's weight. The hitch evens out the trailer tongue weight (TW) load across both truck axles and it also works to control or prevent trailer sway. The linked article and video will give you good background on these systems. The way to select a WD system is to determine the actual loaded trailer TW, with all of your usual gear and supplies in place and with...

  • Will Exceeding Truck's Towing or Payload Capacity Damage Suspension Components
    Failed suspension components like what you described on the F-150 you perform work on can certainly be from exceeding its payload or tongue weight capacity from an overloaded bed and trailer. It's hard to say for certain that this is the culprit as I'm not sure exactly how heavy a trailer he tows with the truck but the fact that it keeps happening (and way sooner than it should) after repairs indicates that something is indeed being overloaded. Based on my research the 2005 Ford F-150...

  • Recommended Timbren Rear Suspension Enhancement System for a Lifted 2011 Ford F-150
    The Timbren Rear Suspension Enhancement System part # TFR1504D is for 4 wheel drive models, part # TFR1502D is for 2 wheel drive models, and part # TFR1504D-P3 is for 4 wheel drive models that have been lifted 4". The weight capacities are different for the 4 wheel and 2 wheel drives models because 4 wheel drive models are heavier and require stiffer springs than 2 wheel drive models. For your 2011 Ford F-150, I recommend using part # TFR1502D if your truck is 2 wheel drive or part #...

  • Suspension Enhancement Recommendation for a Lowered 2005 Ford F-150
    We do have a suspension enhancement kit that will work with a lowered 2005 Ford F-150, but it is an Air Lift kit. Take a look at the Air Lift SlamAir springs for lowered trucks, # AL59210. This kit was designed for trucks that have been lowered 2 to 6 inches. Since you are at 2 to 3 inches this kit would be perfect for you. You can fill these air bags up if you have a compressor at home or by using a gas station air compressor or you can add an on-board unit like # AL25592. It will allow...

  • Rear End of 2011 Ford F-150 Still Sags Even with Weight Distribution
    The problem that you are experiencing is a common issue with 1/2 ton trucks like your 2011 Ford F-150. The rear suspension on 1/2 ton trucks will still allow some sag even when using weight distribution. While making some adjustments to the set up of the weight distribution system might help ultimately you will likely need some rear helper springs to eliminate the sag. The helper springs don't have to be air bags. You could use Timbren Rear Suspension Enhancement System Item # TFR1504D...

  • Selecting Timbren Rear Axle Jounce Spring Kit for 2013 Ford F-150 Ecoboost
    The Timbren rear axle jounce spring kits we have for your 2013 Ford F-150 Ecoboost are shown on the linked page. In your application I suggest the 6K-rated kit # TFR1502D if you have a 2WD truck.

  • Helper Springs for a 2014 Ford F-150 with Full Truck Bed and towing 7,000 Pound Trailer
    Even with the bed on your 2014 Ford F-150 loaded and towing a 7,000 pound trailer the weight on the actual rear axle of the truck is still well under 6,000 pounds so going with the 6K rated Timbren springs, # TFR1504D for 4x4s or # TFR1502D for 2-wheel drive models will work well. The 7K kits are designed for severe service vehicles only.

  • Can Timbren Rear Suspension Enhancements Be Used With Weight Distribution On 2008 Ford F-150
    The use of rear suspension enhancement along with a weight distribution kit is not recommended. They will tend to work against one another. If sag on your 2008 Ford F-150 is caused by a load or a fifth wheel or gooseneck trailer then suspension enhancement is the way to go If your F-150 is a 2-wheel drive I recommend part # TFR1502D. This system helps provide additional support to give you a smooth, comfortable ride and will not affect the ride when your truck is empty. It will become...

  • Timbren Rear Helper Springs for a 2013 Ford F-150 Crew Cab with Heavy Duty Payload Package
    The Timbren helper springs are going to be an excellent choice and what I recommend for loads/cargo carried in the bed of the truck. For your 2013 Ford F-150 there are a few options depending on how the truck is configured. If it is a 4x4 with stock ride height (no factory or aftermarket lift) and not an SVT Raptor then use # TFR1504D. If it is 2-wheel drive, stock height, not a Raptor use # TFR1502D. If it was a 4x4 Raptor with stock height you would need # TFR1504R. And if it...

  • Suspension Enhancement for a 2013 Ford F-150 with Draw-Tite Gooseneck Trailer Hitch Installed
    Firestone Ride-Rite kit # F2542 is designed to work ONLY on trucks that have a B and W hitch installed. Since you have a Draw-Tite hitch we can scratch this one off and look at kit # F2525. Kit # F2525 has brackets that mount to the outsides, bottoms, and a little on the insides of the truck frame rails on your 2013 Ford F-150. The Draw-Tite gooseneck hitch for your truck also has brackets that mount to the outsides of the frame so kit F2525 will not work with the hitch installed. A...
