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.

serve its purpose. just something extra to help with my towing



by:

Made a huge difference - not just in load management when hauling 30 sheets of plywood, but greatly improved the handling & ride in my front-wheel drive work van. I just traded in for a newer model van, so I'm getting the same units again!



by:

These look like they will cure the evils of the heavy load God's. Easy to install and they look like they are quite stout. I will find out in a couple of weeks from now.



by:

Hitch fit great and the instructions were easy to follow.



by:

Install was easy. Raised our Thor Gemini up as product said it would. Great job etrailer!



by:

had this product before. left it on my old truck when I traded. Now I have to replace it, really like what it does for my towing a travel trailer. just have to find time to put it on. speedy delivery arrived undamaged, which is nice.



by:

They definitely reduced sway and lean when driving. But also seems like you really feel every bump and increase road noise?
I assume since vibration from axle can now travel directly to frame?
Might need to upgrade shocks?
Might soften liitle over time?
Might need to get softer onesv
Only have gone 80 miles with them so far.
Will give it another few hundred miles and see what feel then.

Overall pretty happy So far.

Strainer/basket is holding up well after one year of use in our RV, no issues.



by:

Works great on my 2016 town and country for hauling my pop up camper.



by:

Customer service is exceptional and any questions were answered immediately



by:

Good product, I’ve attached a couple photos. The last one is a before and after



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.



by:

Great fitment



by:

Fast Shipping



by:

Very easy to install



by:

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.

  • Recommended Timbren Springs to Help Bottoming Out in 2007 Nissan Xterra
    For your 2007 Nissan Xterra I recommend going with the Timbren Active Off-Road Bumpstops # TABSJRC01 that you referenced. These are really designed for exactly what you're needing them for on your Xterra. They will replace your factory bumpstops and while they won't completely prevent you for bottoming out (no suspension enhancement system will), they are specifically designed to cushion the impact when it does happen so you don't experience that spine-crushing jolt. I actually also called...

  • Rear Helper Springs for a 2014 Nissan Xterra 4x4 Towing a 5,000 Pound Trailer
    For your 2014 Nissan Xterra 4x4 I recommend the Timbren helper springs # TJRC01. Timbren springs get progressively stiffer the more weight is put on them to better support the vehicle when under load. When not loaded or towing a trailer you may experience a little bit of a stiffer ride. I have included a link to our help article on Timbren springs for you.

  • Timbren or RoadActive Suspension Kit Recommendation for 2012 Nissan Xterra
    Overall the RoadActive Suspension kit part # RAS4529-XT will be better. It will give you the additional support you want, it will help make the vehicle handle better, but what really makes it stand out is that it won't make the ride quality as harsh as the Timbren # TJRC01 would.

    For your 1999 Jeep Cherokee, the Timbren Suspension Enhancement System - Rear Axle # TJRC01 and front suspension # TJFC01 are confirmed to fit your vehicle. Both install where your factory bump stops are and help with the stability and load of your Jeep. They help reduce body roll and keep your Jeep from squat under the trailer weight. They are a big help when under load and won't engage unless you hit a big bump when unloaded. They are a firm aeon rubber material, so if you want...

  • Recommended Suspension Enhancement System for Occasional Towing with 2010 Xterra 4x4 on Rough Roads
    I recommend the SumoSprings # SSR-210-40 for your 2010 Xterra 4x4 since you'll be towing and hitting rough roads occasionally. These are specifically designed to provide extra support to your existing springs while maintaining a smooth ride when driving down the highway without additional weight. The Timbren Suspension Enhancement System # TJRC01 is better suited for vehicles that tow heavy loads on a regular basis and they may be a little stiff on rough roads. Please check out the attached...

  • How Tall are Timbren Springs # TJRC01 for a 2014 Nissan Xterra
    The springs in Timbren kit # TJRC01 for your 2014 Nissan Xterra are 3-3/4 inches tall. They also come with 1 inch spacers should you need the additional height. Once installed there should be just a slight gap between the top of the axle and the bottoms of the Timbren springs. I have included a link to the instructions for you.

  • Recommended Timbren Suspension Enhancement for a Lifted 2008 Nissan Xterra
    You can absolutely still use the Timbren Suspension Enhancement System # TJRC01 with your lifted Nissan Xterra however you're going to need to use a spacer # A25723-90AH00 or 1" or # TA25722-90F00 for 1/2". To find out how many spacers you're going to need, you'll need to measure the distance from the underside of your frame where your bump stop sits to the axle directly below where the spring makes contact.

  • Suspension Enhancement for 2000 Jeep Cherokee with 1.75 inch Lift
    I have a solution for your, but the Air Lift kit you mentioned can't be installed on lifted vehicles since there isn't a spacer kit that will work with it. Instead you'll want the Timbren kit part # TJRC01 which fits your vehicle and then you'll need to use a spacer on either spring part # A25723-90AH00 and you'd be set. You'll need to provide longer hardware to attach the spacers as that's not included.

  • Recommended Suspension Enhancement for a 2013 Nissa Xterra that Bottoms Out and Sways
    The Timbren # TJRC01 provides the leveling and stabilization you are looking for. These rear axle suspension rubber springs replace your factory original bump stops and require no drilling to install. Typically, we only recommend the front suspension if you are using a snow plow or carrying a front load. I recommend starting with the rear and if that doesn't perform to your desired stiffness, then upgrade the front suspension as well. Adding a more rigid setup to both axles could make...

  • Will Suspension Enhancements for Towing Work On a Lifted 2000 Jeep Cherokee
    The only option we have for suspension support that will fit a lifted 2000 Jeep Cherokee is from Timbren, the Timbren Suspension Enhancement System part # TJRC01. In order to be compatible with the lift you'd need to add spacers to compensate for this, part # A25723-90AH00 is correct and can be stacked. There aren't any spacer options from AirLift or SumoSprings for this vehicle and they won't work as is with a lift.

  • Timbrem Vehicle Suspension Enhancement Recommendation for 1998 Jeep Cherokee with 2 Inch Lift
    The Timbren Heavy-Duty Front or Rear Suspension Enhancement System, # TJRC01, does come with a spacer designed to adjust ride height which will take up some of the space created by the 2 inch lift. However, you will most likely need to use spacers as well. We have 1 inch spacers, # A25723-90AH00. I would recommend using the front kit, # TJFC01, if you plan on carrying a plow on the front or doing some winching, or if you are looking for more stability at the front of the Jeep.

  • Helper Springs for a 2007 Nissan Xterra S-V6 4x2 Towing 4,500 Pound Travel Trailer
    For your 2007 Nissan Xterra I recommend Timbren springs # TJRC01 which is going to help with rear end sag as well as reduce body roll (side to side movement) and overall greater stability and reduced stress on the factory suspension. The StableLoad system, # TLA7311, engages overload springs sooner so the stress is still on the factory suspension. This is a good option if there is something on the vehicle preventing installation of helper springs but for your situation I would go with...

  • Should the Timbren System part # TJRC01 Fit Loosely
    The Timbren System part # TJRC01 that you referenced should not fit tightly. I spoke to my contact at Timbren and he advised me to tell you that you would want to assemble system off of the vehicle on a work bench using vise grips to hold the assembly so that you can get everything torqued down good and tight and then install it on your Nissan Xterra.

  • Will Timbren Springs Eliminate Sag on 2011 Nissan Xterra Towing a Horse Trailer
    Sag caused by the tongue weight of a trailer is best resolved using weight distribution, not suspension enhancement, but if you do not want weight distribution then using Timbren springs would help. And they would likely eliminate most, if not all, of the sag on your 2011 Nissan Xterra. The Timbren springs # TJRC01 are rated for up to 3,000 pounds so they can easily handle the tongue weight of your horse trailer loaded or empty. I have included a link to the installation instructions for you.

  • Which Timbren Spacer Kit is Needed for a Lifted 2014 Nissan Xterra?
    Hey Alex, welcome back! There's a couple of options for spacers depending on how tall of a lift your 2014 Nissan Xterra has. Timbren recommends leaving a 1/2" gap between the item # TJRC01 and where they contact on your Nissan. How big of a gap do you have between your Timbren's and where they contact on your 2014 Nissan Xterra? If you haven't installed them yet you'll want to measure from the bottom of your frame to the top of where they contact and subtract the total height of your...

  • How To Prevent Sag While Towing with a Lifted 2012 Nissan Xterra
    I do have an option for you but the SumoSprings Solo Custom Helper Springs part # SSR-210-47 are not the best option for a lifted vehicle because they don't come with spacers nor are they offered separately. The option to make your own spacers is certainly possible however, if you use the Timbren Suspension Enhancement System part # TJRC01 which is a very similar kit you can use a combination of both part # TA25723-90AD00 and part # TA25722-90F00 until you get the gap down to 1/2"-1-1/2"....
