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.

  • Recommended 5th Wheel Hitch for a 2016 Nissan Titan XD SL
    To add a 5th wheel hitch to your 2016 Nissan Titan XD you will first need the Demco 5th Wheel Rail Adapter for Nissan Titan XD OEM 5th Wheel Towing Prep Package item # DM6200. This adapter attaches to the integrated gooseneck hitch that come from the factory on your Titan and will provide you with a set of industry standard rails. For a 5th wheel hitch, I recommend the Curt A16 5th Wheel Trailer Hitch w/ R16 Slider item # C16521. This sliding 5th wheel hitch has a 16,000 lbs capacity....

  • Will Timbrens Cause Pogoing On a 2017 Nissan Titan XD
    The Timbren Suspension Enhancement System part # TNRTTNA is a great option for a 2017 Nissan Titan XD. It should engage fully with that amount of tongue weight so there should not be any pogoing but then again, this is not something that we can really arcuately predict. In order to provide support you must stiffen the suspension so a decrease in ride quality in inevitable. If you are concerned with pogoing, the best option would be something that engages right away like air bags, the Air...

  • Will the Timbren Suspension Enhancement System Fit a 2016 Nissan Titan XD with 3 Inch Lift
    Yes, you can install the Timbren Suspension Enhancement System part # TNRTTNA on your 2016 Nissan Titan XD with a 3" lift. However, you need to also install multiple Timbren Spacers part # A25723-90AH00 equal to the height of your actual lift in order to compensate for this.

  • Does Installation of TNRTTNA on 2018 Nissan Titan xD Require Removal of Axle U Bolts
    When installing the Timbren # TNRTTNA you should only need to loosen the axle U-bolts, and not completely remove them. I can't say that it would be the worst idea to replace a bolt that was likely torqued to install, but it's not something we carry. Most likely these would be specific to your 2018 Nissan Titan xD so you would need to source those from an auto parts store or your Nissan dealer. From what I was able to find from my research it looks like those bolts are designed to be torqued...

  • Timbren Suspension Enhancement For 2017 Nissan Titan XD With 6 Inch Lift
    Yes you can use the Timbren Suspension Enhancement on your 2017 Nissan Titan XD with a 6 inch lift. I would go with four additional 1" spacers on each side, so a total of eight. What you will need is the following: - Timbren Suspension Enhancement System # TNRTTNA - Timbren 1" Spacer # TA25723-90AD00

  • Rear Suspension Enhancement Kit Recommendation for 2017 Nissan Titan XD 2WD
    I am looking at their online fitguide and they call out the fit of the part # TNRTTNA for your 2017 Nissan Titan XD if it is a 4 wheel drive which also matches the fit info they gave us when we listed this part number as a fit for your truck. Since you have a 2 wheel drive truck a much better option that is a confirmed fit is the # RAS3611. With this kit you get better support than the Timbren plus a better ride quality overall.

  • Can I use the RoadActive Suspension Kit With The Timbren Rubber Springs?
    Since the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611 uses a different mounting system then the Timbren Suspension Enhancement System # TNRTTNA you will be able to mount both of them on your 2018 Nissan Titan XD. You may need to temporarily loosen and possibly remove the RoadActive system from the mount on the U-bolts to install the Timbren Springs below the U-bolts on the leaf springs. Remember these systems will not increase your maximum payload or towing. They...

  • Timbren Springs or Air Bags for 2016 Nissan Titan XD Pulling 5th Wheel Trailer
    For the type of weight that a 5th wheel trailer will be putting on the rear axle of your 2016 Nissan Titan XD I like the capacity and durability of the Timbren Jounce-Style Springs # TNRTTNA. Unlike air springs these also won't require any adjustments or maintenance after the initial installation so you can simply hook a trailer up, load the bed up, or head out on a Sunday drive without having to worry about making the appropriate adjustments on the springs. It also looks like all of...
