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. 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.

This is the way to go when u need extra support, it has been a great help when towing heavy



by:

We would not be without the product and will go to the site. It is wonderful!



by:

Great product. Huge improvement over stock and easy to install. I have put them on my last several trucks.



by:

I received this item which I thought was new but someone had been through my item its an open box. SO I don't know if this came directly from etrailer or Timbrem its for sure an open box I should send it back just because. I am not happy getting an open box item someone has been through.



by:

bought a couple things from your site and i could not be more pleased--everything about my experience was first class--i will be looking to buy from you in the future



by:

Does the job and easy to install. Does make for a little rougher ride while towing but I’m used to it now



by:

Easy to install



by:

Didn't have all the hardware, I have to go buy all the nuts.(Didn't want to just say I have no nuts). But the product looks great and was a very easy install.



by:

Works great. Still looks like new after a year and we use it hard.



by:

this fit perfectly on my 2016 nv2500. It really helped with my sag. would not hesitate to buy again.



by:

Working really well, should have bought this first. Very easy to install.

by:

This is my second vehicle with the Timbren system. Simple to install and they work Awesome.



by:

These have helped with squat and swaying but definitely rough the ride.



by:

Install was a snap. Works as anticipated. Leveled out our 2014 F-250 very well when loaded vs without.



by:

I love the product, usps keep pushing back my delivery date, so you should give yourself plenty of time ordering them before you need them. Other than that. Awesome.



by:

Pricey, but effective. The ride is unaffected when not towing. While towing, there is a bit more bounce on uneven rough pavement. Great on smooth even pavement.



by:

Very easy to install and they worked as indicated keeping the back of the truck level.



by:

Big difference in sway , ride quality is good.



by:

Gave alot better support and ride without having to deal with adding air. Hook and go.

  • Is There A Spacer Available For A SumoSprings Solo Helper Spring On A 2019 Nissan Titan
    As you mentioned your 2019 Nissan Titan being a work truck there will be another option, but there is no spacer available for the SumoSprings Solo Custom Helper Springs # SS95GR, unfortunately. With that said, as the # SS95GR is rated to 1,500 pounds of capacity, you may want to go with a higher rated product, like the Timbren Rear Suspension Enhancement System # TNRTTN. This will have a 6,000 pound capacity and will do a better job for getting rid of the sag, but I do have to mention...

  • Recommended Timbren Suspension Enhancement System for 2010 Nissan Titan
    Since you are towing a travel trailer, you are going to want to use a Timbren system that enhances your rear suspension. Should your 2010 Nissan Titan be a 4 wheel drive model you would want # TNRTTN, and for 2 wheel drive models you'd want # TTORTUN4. This system is going to level out your ride and help reduce sag when hauling heavier loads. They install without requiring drilling and replace your axle's bump stops. I've included a photo showing what a Timbren looks like installed on...

  • Does Timbren for 2019 Nissan Titan Install On Bump Stop Bracket or Leaf Spring
    The Timbren install pictures you saw might have been from a different vehicle as the # TNRTTN that you referenced installs by attaching to the bottom of the bump stop bracket that you found.

  • Is the 1/2" Spacer # TA25722-90P00 Compatible with the Timbren # TNRTTN on a 2017 Nissan Titan
    Yes, the Timbren 1/2" Spacer # TA25722-90P00 is compatible with the Timbren Rear Suspension Enhancement System # TNRTTN for your 2017 Nissan Titan. Please note that per the linked instructions for the suspension kit Timbren says that there should be a 1/2" - 1-1/2" gap between the rubber spring and contact point when there is no load in the vehicle. If you installed this kit and you have 1/2" of space then you actually won't need the spacer.

  • Will Timbren Kit for 2017 Nissan Titan Provide Support Even with Weight Distribution
    The Timbren kit part # TNRTTN is a confirmed fit for your 2017 Nissan Titan and is going to provide you with additional suspension support when towing. Typically you don't need a kit like this if you already have weight distribution but if you are near the capacity of the truck additional suspension support will help so this would be a solid choice for you.

  • Recommendation for a Rear Suspension Enhancement for a 2004 Nissan Titan Pickup
    I have a solution that is the confirmed fit for your 2004 Nissan Titan. Unfortunately, the Air Lift AirCell Helper Springs that you asked about will not fit a 2004 Nissan Titan. These helper springs will only fit full-size Ford pickups. For your Nissan, I recommend the Timbren Rear Enhancement System, # TTORTUN4 for 2-wheel dive or # TNRTTN for the 4-wheel drive model Titan. The Timbren system will improve the suspension and handling of your loaded Nissan Titan. The Aeon rubber springs...

  • Will Timbren Suspension Enhancement System Increase Payload of 2012 Nissan Titan Pro 4X?
    Adding suspension enhancement like the Timbren # TNRTTN you referenced does substantially help with load support and reducing sag, however it does not increase the payload capacity of your truck. Your 2012 Nissan Titan Pro 4X will have the same 1850 lbs of payload but the system will assist with stability by reducing squat, reducing body roll, and assisting with shock absorption. It will assist far better than adding a leaf spring as that will change the ride of your truck when not...

  • Which Timbren SES System for 2017 Nissan Titan SL
    For your 2017 Nissan Titan SL you will actually need the # TNRTTN and not the # TNRTTNB, which is only designed to fit on the 2017 Nissan Titan Pro-4x. The difference isn't the ride height, but the available mounting spots for on the two trucks are slightly different. This system will install on your rear axle and provide you with a great system to help reduce vehicle sag when towing or carrying heavy payloads.

  • Will the Timberens part # TNRTTN Work on my 2018 Nissan Titan with an Equalizer Weight Distribution
    Great news! The Timbren Rear Suspension Enhancement System part # TNRTTN will work out great with your 2018 Nissan Titan and will work perfectly in conjunction with your weight distribution system.. With your equalizer system as part of the equation I recommend after installing the Timbrens that you re check the system per the instructions to ensure that the system is still optimized and does not need fine tuning.

  • Towing Fifth Wheel Trailer With 2006 Nissan Titan
    From what you describe, your trailer isn't very heavy. Pin weight can range from 15-20 percent of the trailer weight, or up to 25 percent for some larger toy haulers. Worst case scenario, you're looking at about 1500 lbs or so of pin weight which is pretty minimal. To determine the towing capacity of your truck, take a look at the sticker on the driver's door jamb. Look for the GCWR, the gross combined weight rating. This represents the maximum amount the trailer and truck can weigh....

  • Do Firestone Ride-Rite Rear Air Springs, Part # F2355, Fit 2010 Nissan Titan with a 5th Wheel Hitch
    My contact at Firestone does not have a confirmed fit for this air spring kit, part # F2355, on the 2010 Nissan Titan when it is equipped with the mounting hardware for a 5th wheel. This does not necessarily mean there will be a fit issue, only that the combination is untested. The compatibility of this air spring kit with your 5th-wheel-equipped Titan will be a function of the type of base rail installation kit you have and where on the vehicle frame that hardware is mounted. If it mounts...

  • Can Timbren Suspension Enhancement Be Used With Weight Distribution System On 2005 Nissan Titan
    You can use a Timbren Rear Suspension Enhancement System, part # TNRTTN on your 2005 Titan with a weight distribution system. The Timbren system is designed to help increase stability and reduce sag when weight is added to the back of a truck. I would recommend adjusting the weight distribution system after installing the Timbren system to make sure it is set up correctly for your camper and any of the load you put in the bed of your truck. The Timbren system will not affect the ride...

  • Comparing The Timbren # TNRTTNB And # TNRTTN For A 2024 Nissan Titan SV
    Hey Mitchell, The Timbren Suspension Enhancement System # TNRTTNB is designed specifically for Pro 4x models so it wouldn't be the right fit for your SV. Both the # TNRTTNB and # TNRTTN (which would be a fit for your SV) have 5" tall springs. The # TNRTTNB uses HCS M8 x 50 x 1.25 Grade 8.8 zinc coated bolts and the # TNRTTN uses HCS M10 x 40 x 1.5 Grade 8.8 zinc coated bolts. These both have a 6,000lb capacity and will make a significant difference to your unloaded ride quality. I personally...

  • Suspension Enhancement Recommendation for 2006 Nissan Titan That Will fit with 5th Wheel Rails
    It looks like the Firestone kit part # F2355 could fit on your vehicle with fifth wheel rails # C16470-204, but since it hasn't been tested we really can't say for certain. The safe bet would be the Timbrens that we know will fit. Such as the Timbren kit # TTORTUN4 for 2-wheel-drive Titans (or part # TNRTTN for 4-wheel drive models). Since these springs install in place of the OEM axle bump stops there is no conflict with 5th wheel mounting hardware. Also, since these springs do not...

  • Rear Suspension Enhancement Recommendation for 2010 Nissan Titan with 1 inch Lift
    A shackle lift is considered a suspension lift since it raises the frame of the vehicle away from the axle. So you would need lift spacers to use a suspension enhancement kit. I have a very similar solution, but the Work Rite kits don't have lift spacers available. You would want the very similar Timbren part # TNRTTN and then the 1 inch lift spacer # A25723-90AH00 and you would be set.
