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.

by:

Works great on my Honda odessey !! Great customer service as always!



by:

Very fast shipping, had product in 2 days! Very easy to install. Hardest part was lifting the RV.



by:

Fast delivery. Disappointed with the instructions. Sense the item was ordered vehicle specific. The instructions said tighten bolts to manufactures specifications.



by:

The product first arrived in a damaged box with one of the washers missing, but ETrailer did resupply that. The hardest part was finding a shop able (needs the right tools to depress coil springs) and willing (a potential liability issue messing with suspension) to replace it for a reasonable cost. Eventually a local tire shop agreed to. This was for a 2014 Honda Odyssey, especially for pulling a pop-up. Took two camping trips last summer, one before and one after installation, and I have been pleased with the added stiffness in the rear suspension. It made about 1 to 1.5 inch of difference in resting position when fully loaded and towing and has helped smooth out bumps and humps in the road - both when towing and not.

Great fitment

BIG difference in handling a load or trailer ... what a great product!!!



by:

Have not driven yet, just installed. Added Monroe coil-overs as well, thanks etrailer.



by:

Excellent quality, good prices and great shipping ! Thanks



by:

Delivery was fast, instal was quick & easy. Later today I will see how they work when I hook up to the 5th wheel. By all indications right now I believe they exceed my expectations.



by:

I put this product on my Trooper. The install was easy is you take the back wheels off. I towed this weekend and I did not bottom out. If they hold up over time, this is a great product.



by:

I would recommend this product to anyone. I pull trailers with a 1/2 ton truck and will never have another one without this product on it.



by:

Price was good compared to other sites. Shipped very fast. Installation was very easy.



by:

Put them on and it is exactly what I need to keep truck level when hauling fifth wheel. Easy to install too



by:

Offers firm suppirt for loads. A little bouncy with no load. Easy to install.



by:

Fit and functions as described. Installation was simple on my '05 Silverado.



by:

It took longer to move the floor jack under the truck then to install them. Maybe 10 minutes total. Thanks Rex



by:

15 mins to install and what a difference…. Went from a few inches of sag in the rear to only an inch and over 1000lbs tongue weight didn’t know the trailer was attached to the truck



by:

This product was delivered quickly and efficiently. The quality of the product is excellent and look forward to seeing how they work when we are towing our trailer.



by:

Holding up good a year after purchase, work great for pulling my camper

  • Does Timbren Suspension Kit Increase Towing Capacity of Vehicle
    Hey Kyoung, so the Timbren suspension kit part # TNRNVHD does provide an additional 6,000 lbs of suspension support but it does not actually increase the vehicle's towing capacity. Instead it basically just beefs up the suspension so that it doesn't sag as much which helps create a safer driving experience when loaded.

  • Recommended Suspension Enhancement For 2020 Nissan NV 2500
    I have another suspension enhancement option for you, but at this time there is not a Firestore or Air Lift Air Helper Spring Kit that is confirmed to fit your 2020 Nissan NV 2500. While you are correct that the 5.6l V8 engine is the same engine used in the Nissan Titan, the suspension is different between the two. For your NV 2500 I recommend the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3614-T as it offers 2000lbs of support for your suspension, but also due to it...

  • Suspension Enhancement Options For 2020 Nissan NV 2500
    Seems like you're needing some suspension enhancement! I recommend using the RoadActive kit # RAS3614-T. This will help your suspension from 0 to 100% travel. It's also adjustable to get the right amount of support. If that's not enough, get some helper springs # SSR-210-47 in the rear, these will only engage when your vehicle sags enough to hit the bump stops. If you're only looking to help the last half of your suspension travel and not hinder your smooth ride when you're not hauling,...

  • Suspension Enhancement that Fits 2014 Nissan NV 2500
    We have suspension enhancement kits that fit your 2014 Nissan NV 2500 like the Timbren part # TNRNVHD but we do not have any air bag kits that fit.

  • Is There An Air Bag And Compressor Available For A 2017 Nissan NV 2500
    Though I may have another option, I checked with Firestone and Air Lift and, unfortunately, neither currently make a kit that will fit a 2017 Nissan NV 2500. With that being said, the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3614-T is a highly recommended product. These do a very good job of helping with squat issues as well body roll and sway. The install is pretty quick and easy, and as long as you can jack your vehicle up by the frame, it is also pretty easy to...

  • Recommended Suspension Enhancement System For 2015 Nissan NV 3500
    The Firestone System, part # F2430 you mentioned is not a fit for your 2015 NV 3500 but i do have a solution that will work for you. I recommend the Timbren Suspension, part # TNRNVHD. This is a simple installation by replacing the bump stops on your vehicle. These do not effect the ride when your Nissan is not under load. As more weight is added these springs act independently to act as a shock absorber and give you a much smoother ride. No drilling is required when adding these springs....
