Reduced rear axle sag with Timbren suspension enhancement

Whether you're hauling heavy loads in your bed or cargo area or 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 your rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the leaf 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.


Action 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.


Trailer swaying as it is towed behind a truck

Because your 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 SES

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.

Very easy to install even though the istructions haven't been updated to the '17-'19 model year Titans. You have to remove the bump stop that is mounted to the top (instructions show it mounted to the leaf spring). To install the bump stops simply pull out, then you remove the mounting plate with a 1/2" socket, then follow the included instructions. I bought this to help my pickup sit more level and to help provide a little extra lateral stability in crosswinds when towing my travel trailer. It certainly helps with being more level, but I haven't towed in the wind yet to see if it helps in that area. I measured the top of the tire to the fender and it is 5.5" in the front, 5.25" in the rear with the travel trailer fully loaded and ready for camping. I gave this four stars because it looked like it was used when it showed up. It doesn't have to be pretty, but I really don't like buying new items and receiving used ones.

The Timbren Aeon Spring System Vehicle Suspension was easy to install on my 2005 Nissan Titan. The only problem I have is that the, per the Timbren instructions, your load is only taken on by the Tembren (rubbers) after the load on your vehicle's leaf springs depressing allows contact with rubbers. Only on my truck the it's the opposite. I'm riding on the rubbers without any extra weight in my bed, causing a very uncomportable ride, and a lot of unnecessary bouncing around. It's great when I'm pulling my 26' travel trailer, or my fully loaded 16' wood hauling utility trailer. They also make the back of my tailgate higher, making it harder to load and unload. After I bring my travel trailer down from my hunting camp the Timbren rubbers are coming off.

I installed the timbren rear suspension system... I have been very happy with the product and would encourage anyone looking to enhance tow capacity of a truck to use this system


Comments
Glad to hear that you are happy with your Timbren suspension kit! Please just keep in mind that while this kit does enhance your vehicle suspension, it will not increase the actual weight capacity of your vehicle. This is the same among all of the suspension enhancement products.

Unhappy with the unloaded ride quality when installed on my Nissan Titan, especially on rough roads! Timbren should have used a much softer rubber spring for this application. I chose to remove these after only one week because I could not tolerate the ride. Unfortunately I didn't experience this product under a loaded condition when pulling my travel trailer. I am going to try the Firestone Workrite product next (I hope it is better), sine I want to stick with an airless helper spring system.

This is the second truck that I own which I have them on. I have them on my Ford diesel truck which I pull a 12000 lb 5th wheel, and now my nissan truck for pulling my boat and 4 wheeled. These are a great cheap investment which I recommend.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I used this on my Isuzu tow truck. The blocks in and of themselves are fine, they support the weight. Here's the problem: They are pre-loaded, meaning that they always touch between the frame and the rear axle. As you load the vehicle this puts more pressure on the frame in this 5" area where the blocks are. The springs have not yet taken as much weight as they normally would. Now, all this upward pinpoint pressure bends the frame. This is what happened to me on my rollback tow truck. After many hours and now double plating the frame all is well again, but a tremendous amount of work. Yes, the blocks are fine, but the result of installing this product resulted in a bent frame. The vehicle was not overloaded and was within the GVWR.

I have reached out to the manufacturer who will be reaching out to you.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Product is high quality, all parts fit well and I didn’t have to force anything. High strength thick steel, and the jounce bumpers are seriously heavy duty. I haven’t had a load on the truck (98 Ram 3500) since install a few days ago, so they haven’t touched the base plates yet. One thing I’m concerned with is the jounce bumpers are touching and are right up against the lift blocks and U bolts. I’m unsure of the longevity these bumpers will have after a heavy load is on them and they are constantly rubbing on the hardware. Also, as the load gets heavier they expand outward as they flatten out so I’m also concerned with if that will push my lift blocks outward and mess with the suspension. I’m prepping for a slide in camper and when I get it I will have to take a look and see what effects that weight has on the suspension, the bumpers, and ride quality.


Comments
I am not sure when I will be able to have a load on it to confirm, as I do not have a camper just yet. I am currently working on upgrading the suspension in preparation for one. Is there an alternative similar solution, other than airbags - as I dont want those, that can be run? With a similar weight capacity? Kind of interesting Timbren hasnt run into this issue before with the older Ram 3500s. Wonder if this is somehow unique to my truck? All the rear components are original OEM, so it seems kind of strange.

Comments
You mentioned that the jounce bumpers were touching up against the lift blocks without a load in the truck and I wondered if you could send a picture of the installation?
-- Etrailer Expert Jenny N - 01/05/2022

Comments
I do have additional questions for you. Is the top picture showing how the springs look with a loaded weight? Have you already installed your slide in camper? I wanted to see if the top bracket were touching as well? The manufacturer is trying to determine if a smaller diameter spring would help or not
-- Etrailer Expert Jenny N - 01/05/2022

Comments
Both pictures are right after installation with a completely unloaded bed. Since installation, I have not had weight in the bed, so I can not 100 say if the top brackets would touch the U bolts or leaf springs. But from looking at it just now, it appears the top bracket would just barely touch the U bolts with a loaded bed, and would definitely touch if there was side to side movement with a loaded bed like going over a speed bump, pot holes, or uneven terrain.
-- comment by: Jimmy - 01/05/2022

Comments
I did hear back from Timbren. Currently there is not a bracket that would be narrower that they can offer. When loaded if the brackets interfere with the smaller spring, then it may be advisable to return the kit.

I was researching if I had an alternative and I realized that I needed to confirm your set up. Do you have the 3500 cab and chassis - if yes was it always a cab and chassis - or do you have the 3500 pickup? I am under the impression that you have the pick up since you want to use a slide in camper however, I wanted to be sure.
-- Etrailer Expert Jenny N - 01/05/2022

It is the 3500 pickup. Thanks!
-- Etrailer Expert Jimmy - 01/05/2022

Comments
I believe I now know what happened and I should have asked about the truck before now. The TDRTT3500 that was ordered is used for the cab and chassis model versus the pickup and this is leading to the fitment issues you have seen. I do have two options to offer for the 1998 Dodge Ram 3500 pickup including a different Timbren application. They are part # TDR3500

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


First, this is the third truck have have put Timbren SES on, so I am a big fan of this option for a pickup truck. There is no impact to the ride when the bed is empty, when loaded it is a big improvement keeping the truck is a level position, reduced sway.. I would have given this 5 stars, except the lower bracket is rusting. All the other parts are painted black except this one part - see picture... This is after one year, truck is parked in a garage in NC (not a high snow/salt state)...


Comments
I continue to be a fan, on my 1019 f150, I used the 1 in spacer, works perfect ! I have dumped 2200 lbs of stone in the bed a few times, no problem.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Installed on 98 Ram 3500 pickup. Haven't put a load on it yet, but it installed very easily and fits well. Driver's side spring brackets were a bit harder to install than the passenger side, but still overall easy. One con was the powder coat finish was worn off in spots right after opening the box. Not sure if the packaging is to blame or what, but in general the packaging never seems to be that great on the etrailer products I've ordered (just brown packing paper).

Highly recommend for anyone towing. Leaf springs were flattened out prior to install. Swapped the bump stops out for Timbrens in a campground before making a 1000+ mile trip home. They work amazing leveled the truck out while towing and absorb the bad bumps.

I would absolutely buy the Timbren SES again if I didn’t already have them. No issues after a year.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I have a 2018 GMC Sierra 1500 pick up truck (elevation package) in which I added a 3.5 inch ROUGH COUNTRY KNUCKLE LIFT KIT with Front Struts. The rear distance between the bump stop's metal cup just under the frame and the the rear axle is 8.25 inches with an empty truck bed and a quarter tank of gas. I gave the professional this information on my truck and what I needed; they e mailed back the kit with only 1.5 additional spacers on each side of the truck, Ok. I still came up with 2.25 inch space with an empty truck bed on both sides. I feel More TIMBREN PRODUCTS WOULD be SOLD if websites carried information All together for the average people to buy at their finger tips. It would have been easier for me if the following were all grouped together for my truck : TIMBREN Rear Suspension Enhancement System TGMRCK15S (that has 3/8 bushing) which is actual about 4.5 inches not 5inches in height. FOR TRUCKS with LIFT KITS spacers are required with the same 3/8 bushings 1 inch spacer (that has 3/8 bushing) A25723-90AHOO 1/2 inch spacer (that has a 3/8 bushing) TA25722-90POO I required an additional 1 inch spacer on both sides than I was e mailed. It would also be easier if I could buy the additional bolts grouped with my additional 2.5 spacing on both sides of my truck on the web site, than going to the hardware store. I would pay the additional cost. So all together for my 3.5 ROUGH COUNTRY LIFT, I required 2.5 inch spacers on both sides with the 4.5 height kit which = 7 inches . I haul my 4 wheeler in the bed and broke a level spring years ago. On other occasions I place fire wood in the truck bed. TIMBREN is the way to go, it will be there when I put weight in the bed of truck; be it a 4 wheeler or wood. Friends of mine have air bag systems that leak over time and are much more in price. You can not go wrong with TIMBREN. When installing, remove salt and sand near top of original bump stop bolt, apply PB blast wait 10 minutes use a breaker bar with easy removal. Go to the hardware store to get longer bolts. When installing have to jack up the back of the truck under the towing package to get space to use tools to add new TIMBREN PRODUCTS.

This Rear Suspension Enhancement kit were so easy to install, I was almost sure I missed something. They installed in less than an hour. I was able to place my floor jack under the ball mount to raise the rear end enough to remove the old mounts and simply install the new ones. Hooked up my 28' rv to my Silverado 1500 and they worked as advertised. No front end sag and I feel safer towing it. Customer service helped me find the right product I needed without dishing out a lot of cash!

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Never mess with airbags again on your truck. These Timbren bump stops are the only way to go. Installation took a total of 10 minutes and they work amazing. No messing with airlines, filling or deflating air bags with complicated installation. I’m towing a 44ft trailer and these Timbren bumps stops are a must. Great product but a little pricey for what they are.


Comments
After a year of towing some kind of trailer every week, the bump stops are showing some wear from riding on the bump stop pad on the axle. That being said, they are still working as intended and as good as the day I installed them. After a lot of miles, the only draw back is driving around with no trailer. Normal driving the ride isn’t effected but when you hit a bump in the road you really feel it hit the bump stop. You loose a fair amount of rear suspension travel with these but I’m used to it now.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I really like these Timbren bump stops. I think the best thing about them is the simplicity, both how they work and how easy the install was. I bought these when I added a dump insert (similar to a salt spreader) into my 2019 F-250. I have loaded this truck heavy before with dirt and the truck sagged tremendously and had a lot of body roll. To prevent this with the now added dump insert, I installed these. Super easy to install! Took maybe 30 min. It reduces body roll and seems to improve the ride depending on how loaded the truck is. One unfortunate consequence to the install is that the Timbrens brought to light that I have a weak leaf spring on my passenger side, which was suspect previously. Overall, I'm very pleased with this purchase and would buy again!

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I just installed the Timbren Rear Suspension Enhancement System on my 2019 Ford F-150 4x4. The install was pretty straight forward, but I will say that the written instructions were pretty vague. Reviewing the Video on the e-trailer site was helpful. Also the markings for Left and Right could be improved. The marking “L” was very small and baring readable and the “R” appeared to be under some scratch marks so it was not legible at all. I think this product will help considerably. I have attached photos. The clearance between the rubber spring and the bottom plate is approx 1”. I also previously installed the Equalizer weight distribution & 4 way anti sway system to tow my 30’ Travel Trailer. The Timbren is to prevent any slight squat may occur.

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...

  • Recommendation for Squatting 2017 Nissan Titan 2WD While Towing with a Weight Distribution System
    Thank you for all of the information regarding your towing setup. While we do have suspension enhancement for your 2017 Nissan Titan, you are going to see the most direct benefit by ensuring that your trailer has a tongue weight (TW) that is 10-15% of the weight of the loaded trailer and that your weight distribution (WD) system is set up properly. I recommend using a scale like part # 5780 for the tongue weight and then seeing if bolt-on brackets like the Curt # C17005 or Reese # RP58305...

  • 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.

  • 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...

  • 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....
