An example of sag on a vehicle's rear axle under a heavy load

Whether you're hauling heavy loads in your bed or cargo area or you're 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 the rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the 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.


Animation 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.


An example of a trailers swaying

Because the 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

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall when loaded. 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 when loaded or towing because the rubber has more travel.

  • 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...

  • Do Air Lift AirCell Custom Helper Springs Have a Load Rating
    There is no load rating attached to the Air Lift AirCell Custom Helper Springs Kit AL52218. The note in the linked instructions says that they will not alter the GVWR or payload of your 2013 Ford F-150, so as long as you keep the capacity under those weight limits the kit will provide your F-150 with support from heavy loads. In regards to your second question you would still need to use a weight distribution hitch; the Timbren Rear Suspension Enhancement System # TFR1502D help level your...

  • Can More Than One SumoSprings CSS-1168 be Used at the Same Time
    If the SumoSprings # CSS-1168 is not picking up enough slack on your 2020 Ford Expedition, you can definitely add on to it. I spoke with SumoSprings and they said it is perfectly fine to add on another # CSS-1168 if the first one isn't getting all the sag under control. That being said, as the Timbren # TFR1502D is designed to work on a 2004 to 2014 Ford F-350, I cannot recommend it as a fit. If this does not fix your issue, however, you will most likely need to use a weight distribution...

  • Recommended Suspension Enhancement To Reduce Sag When Towing Trailer With 2012 Ford F-150
    If you have sag at the back of your 2012 F-150 when towing a load that stays pretty consistent then the best way to help with that is by installing suspension enhancement like part # TFR1504D for a 4-wheel drive or part # TFR1502D if you have a 2-wheel drive truck. These are rubber springs that do not effect the ride of your truck when it is not under load but when towing will become more rigid to help add additional support. Air springs like part # F2525 are a better for your truck when...

  • Installation of a Timbren Vehicle Suspension on a 2014 Ford F-150
    Most likely there is a bolt holding the factory bump stop on your 2014 F-150. You simply raise your truck up off the ground and use a 13mm socket to remove the bolt. Take a look at the video I included to see the removal of the bump stop and installation of the suspension, even though it's on a 2010 F-150 and different Timbren suspension # TFR1504D. Once done, you will be ready to install the new Timbren rear suspension enhancement # TFR1502D you referenced. Ideally, the amount of space...

    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...

  • 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...

  • 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...

  • 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.

    The Draw-Tite trailer hitch # 41933 has a tongue weight capacity of 1,000 pounds. But you will want to check the owners manual for your 2006 Ford F-150 to determine its capacity. Whichever is lower, the truck or the hitch, is the capacity you need to go by. In order to be able to carry the motorcycle and the carrier you will need a tongue weight capacity of at least 675 pounds based on the weights you have provided. You will likely see some rear end sag on the truck. To prevent this you...

  • Will Timbren's Work with a B&W Gooseneck Hitch on a 2012 Ford F-150
    Yes, the Timbren Rear Suspension Enhancement System part # TFR1502D for 2WD or part # TFR1504D for 4WD will work with the B&W Turnoverball Underbed Gooseneck Trailer Hitch part # BWGNRK1104 you have installed in your 2012 Ford F-150. The mounting brackets do not interfere with one another as one mounts underneath the frame (Timbren's) and one mounts on the side of the frame (B&W).

  • Will the Timbren Suspension for the Ford F150 Affect Unloaded Ride Height
    When unloaded you will not see a height increase with the Timbren System # TFR1502D installed on your 2010 Ford F150. You should find that when loaded with either cargo in the bed of your truck or towing a trailer that the rear does not sag as much. Bottom line, when unloaded you will not see difference in ride quality or height with the # TFR1502D installed in your vehicle.

  • Can Timbren Helper Springs be Installed on a 2007 Ford F-150 with a Slight Lift
    Yes you can still use Timbren helper springs # TFR1502D on your lifted 2007 Ford F-150. The springs only attach at the top to the truck frame. There are 1 inch spacers included with the kit which you will likely need to use with the lift on your truck. Without the spacers the truck would have to sag more before the springs made contact with the axle.

  • Timbren Rear Suspension Enhancement System for 4WD 2006 Ford F150
    The Timbren Rear Suspension Enhancement System item # TFR1502D you referenced is for 2WD only 2006 Ford F-150s. For your 4WD F-150 I recommend the Timbren Rear Suspension Enhancement System item # TFR150D. This system has a 6,000 lbs weight capacity and will definitely help to address the sagging you are feeling when your truck is loaded down.

    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 treats...

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...

  • Solution for Rear-End Sag in 2012 Ford F-150 Supercab Towing 17-Foot Camper
    Since your F-150 is only 3 years old odds are its spring suspension is still in good shape. For this reason I recommend a weight distribution hitch to correct your rear end sag when towing your camper, rather than a helper spring kit. Helper springs are better for supporting your stock suspension with cargo loads in the truck bed but for your application towing a travel trailer a weight distribution (WD) system is the way to go. You can use the linked page to see all WD systems that also...

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).

  • Solution for Sway of 2016 Ford F150 At 65 mph
    I'm assuming that this isn't happening when you're not towing, correct? When the trailer is hitched up, and the Equal-I-zer weight distribution system is used the trailer is locked into place behind the trailer, more or less forced to track along behind the truck. Ruts or undulations in the pavement can cause the rear truck axle to sway a bit, which causes the yaw you mentioned. Roadmaster offers a rear anti-sway bar, part # RM-1139-177 that will keep the rear truck axle perpendicular...
