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.

Shipping was fast, product looks to be well made.

Product does not help rear swag with fifth wheel camper but a half inch. On brand new truck as well. Not happy with product. Called to return them and want me to pay 27.00 shipping and stated in email that was sent to me I couldn’t return if installed. I’m not understanding this ? Do not buy ! I won’t be doing any more business with etrailer . Not helpful at all



by:

Just installed on 2008 Hyundai Entorouge seems to work well. Only problem was that I had buy new hardware because the supplied hardware was standard not metric.

Works like expected. Keeps the truck looking level even under heavy loads.

Installed in about 15 minutes,very easy.I pick up my new truck camper next week so I do not know how it works yet,but looks like it will work like its suppose too

by:

Just what my truck needed to stop the sag when I hook up to my 5th wheel.



by:

Sorry to report that the Timbren package arrived in original box that looked as though it had been ripped open and the carefully taped shut with clear packing tape. I thought at first that shipper had damaged it but all parts were there so I started install. Half way thru I discovered two of the lock nuts were stripped and threads on the right axle pad were burred at the start. We live 14 miles round trip from the closest ace hardware. I used a die to repair the axle pad threads but had to stop for the day to purchase new lock nuts. Feel like I got a used set for new price.



by:

Very quick delivery, earlier than I expected. Easy to install. Just what was needed for rear weight support when pulling a trailer.



by:

Easy to install and does not affect the ride till you have a load, then they help support the load. Good product!



by:

Great Product, arrived quickly and packaged well.

Will be buying from them in the future.

  • Can B&W Gooseneck Trailer Hitch and Air Bags be Installed at the Same Time on a 1999 Dodge Ram
    As long as the air bag mounting brackets do not mount in the same place on the truck frame as the B&W gooseneck brackets then you can install air bags on a 1999 Dodge Ram. Firestone kit # F2071 would not work because it mounts on the outsides of the truck frame rails the same as the gooseneck brackets. Looking through the other air bag options for the truck all of them have upper brackets that would interfere. Another option is a Timbren set up # TDR1525H2. It can be used on a 1500 or...

  • Will Upgrading Rear Anti-Sway Bar Help Reduce Body Roll on a 1999 Dodge Ram Pickup
    Upgrading the rear factory anti-sway bar with # RM-1129-122 will help reduce side to side body roll. This bar fits 2500 and 3500 series 4x4s only. Other option to reduce body roll is to install some suspension helper springs. If you have a 4x4 with standard height (no factory or aftermarket lift) I recommend # TDR1525H4 which will fit a 1500 or 2500 but not a 3500. For a 3500 use # TDR3500 for a 4x4 or # TDR3500B for 2-wheel drive models. For a 1500 with standard height and 2-wheel drive...

  • Suspension Enhancement Options for a 2002 Dodge Ram 2500 With B and W Gooseneck Turnoverball Hitch
    The upper bracket for the Air Lift LoadLifter 5000 Air Helper Springs, # AL57215, that you referenced bolts to the outside of the frame rail where the frame brackets of your B and W Turnoverball currently sit. I spoke with B and W and they told me that it was okay to bolt through their frame brackets if you would like to install this air bag kit. At this time we do not offer air springs for your 2002 Dodge Ram 2500 that mount to the underside of the frame rail, but we do offer rubber...

  • Recommended Suspension Enhancement for a 2002 Dodge Ram 2500 with 5th Wheel
    The Air Lift LoadLifter 5000 Air Helper Springs part # AL57230 will not interfere with most 5th wheel brackets. However, this kit is for a 2002 - 2008 Dodge Ram Pickup 1500 and since you have a 2002 Dodge Ram 2500 it will not work for you. Unfortunately, there is not an airbag kit that will work for your truck and not interfere with 5th wheel brackets but I do still have a solution for you. I recommend using the Timbren Rear Suspension Enhancement System as this will be your next best...

  • Recommended Suspension Enhancement for a 2001 Dodge Ram 2500
    If you are not hauling a 5th wheel trailer or using a gooseneck hitch the top of the line rear suspension enhancement is going to be the Firestone Ride-Rite Air Helper Springs item # F2071. These air bags fit both the 2WD and 4WD 2001 Ram 2500's. This system offers 4,800 lbs in load leveling support. If you are using an in bed hitch your options are limited. You will want to go with one of our Timbren Kits. The Timbren's act as a bump stop and will prevent your suspension from bottoming...

  • Suspension Enhancement for 2001 Dodge Ram 2500 with B&W Gooseneck Hitch Installed
    I do have an option for you, however we do not have a rear air bag system available that is compatible with an in-bed hitch like the B&W Turnoverball Gooseneck on your 2001 Ram 2500. The mounting brackets for all of the air bag systems will use the same space on the truck frame that is needed for your gooseneck brackets. With this in mind the best solution will be a jounce-style spring that simply replaces the factory bump stop on your Dodge Ram like the Timbren Rear Suspension Enhancement...

  • Correct Timbren Rear Suspension Enhancement System for a 1995 Dodge Ram 2500
    I checked with Timbren and the correct Timbren Rear Suspension Enhancement System for a 1995 Dodge Ram 2500 is part # TDR1525H2 for 2WD models or part # TDR1525H4 for 4WD models. These both offer a bolt-on fit that will provide additional support when towing or hauling. They are very cost effective and one of the most popular options for suspension enhancement.

  • Timbren Front Suspension Enhancement for 2011 Ram 1500 Crew Cab with Snow Plow
    Rubber jounce springs like the Timbren # TDR1525H2 that you referenced help support your suspension when it is under load, but otherwise do not affect ride quality (a good thing). They do not add height to your suspension. Do please note that the kit you referenced is a rear suspension kit for Ram trucks, but it does not fit your 2011 Ram 1500 Crew Cab. If you need a front hitch for your truck to accept a snow plow we offer # 65062 from Draw-Tite. The installation of this item on your...

  • Suspension Enhancement Recommendation for 2001 Dodge Ram 2500 with B and W Gooseneck Hitch
    I have a suspension solution that will work well for you, but due to how the air bag kits install they are not compatible with fifth wheel hitch rails like what you have in your 2001 Dodge Ram 2500. Instead the Timbren kits will work great. If you have a 4 wheel drive vehicle the kit you would need is the part # TDR1525H4. If you have a 2 wheel drive model you instead would want the part # TDR1525H2.

  • Suspension Enhancement Recommendation for a 2011 Dodge Ram 1500 Quad Cab Short Bed
    Basically, the truck is only rated for a certain amount and adding suspension enhancement will not increase the towing capacity or payload. Adding suspension enhancement will just help with ride quality, leveling the vehicle when under load, and it will help protect the suspension. Suspension enhancement is still a good idea for the reasons I have listed above. Since you will be towing a 5th wheel trailer which is a load that does not shift and has a constant weight more or less, I would...

  • Suspension Enhancement Recommendation for 1999 Dodge Ram 1500 with Fifth Wheel Hitch
    The suspension kit you need for your 1999 Dodge Ram will actually have to be a Timbren like the part # TDR1525H2 as the air bag kit brackets are not compatible with the frame brackets of the fifth wheel kits. The Timbren kit I mentioned will provide up to 6,000 lbs of suspension support when needed and won't require any air bag pressure maintenance so in a lot of ways it's a better option than air bags.

  • Air Suspension Enhancement For 1999 Dodge Ram 2500 Truck With Gooseneck Hitch Installed
    We do not offer an air bag helper spring system that will work with your gooseneck hitch installed on your 1999 Dodge Ram pickup truck but I do have a solution for you. If you have a 2WD truck I recommend the Timbren Rear Suspension Enhancement System, part # TDR1525H2. This replaces the bump stop on your truck and helps when carrying a heavy load. This system does not affect the empty ride of your Ram. This is designed to work with a suspension system that is in good working order and...

  • Suspension Enhancement Recommendation for 2000 Dodge Ram 2500 with Gooseneck Hitch Installed
    The only suspension system we can safely recommend as a fit for your 2000 Dodge Ram with a gooseneck hitch installed is a Timbren kit part # TDR1525H2 which is a confirmed fit. The air bag kits all install in the same area as your gooseneck hitch rails so the two can't be used at the same time.

  • Are Timbren Vehicle Suspension Enhancement Springs Needed for 5th Wheel Towing, 1995 Dodge Ram 1500
    The vertical pin weight of a 5th wheel trailer should be between 15 and 20 percent. On an 8,000 pound trailer, that equates to 1,200 to 1,600 pounds pressing down on the bed of the 1995 Dodge Ram 1500. This is a fair amount of weight and will most likely cause some sag at the rear and suspension enhancement can help. The addition of springs like the Timbren Vehicle Suspension, # TDR1525H2, will help keep the truck level and absorb road shock when towing your 5th wheel trailer. They will...
