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.

Video Transcript for Timbren Rear Suspension Enhancement System Installation - 2017 Ford F-150

Speaker 1: Today, on our 2017 Ford F-150, we're gonna be taking a look at and showing you how to install the Timbren suspension enhancement system for the rear axle, part number TFRTT1504E. Here's what our Timbrens look like, once we have them installed. They are going to mount in between our frame and our axle, giving us the support that we need whenever we're hauling a heavy load or towing a heavy trailer.They are going to replace the factory jounce stops and provide us a lot more support, not only because they're taller. As you can see here with our factory jounce stop, it is much smaller. These are more designed to prevent us from actually hitting the frame on the axle, and not really provide any support.Our Timbrens are actually going to get more progressively stiff with the more weight we add, but in the beginning, they're going to be nice soft cushion, so we're still going to have nice ride.Our Timbrens are going to work independently from each other, so it's going to help with those off-center loads or if we're taking a very sharp turn. It's going to help a lot with that body roll, and just the back end of the vehicle sagging, as well.

There's not going to be any drilling required. All the brackets and hardware are included, made specifically for our truck, making installation that much easier.One of the best thing about our Timbrens is once we have them installed, there's no maintenance. Unlike . Air springs are going to require us to monitor and possibly change the inflation inside of the bags, these, once they're installed, we can forget about them. They're going to provide us the support and the smooth ride whenever we're driving down the road.As we come up to our bump course, we have our speed bumps.

I can tell you immediately that you really can feel that in the seat. It is a speed bump, but it's definitely resonating a lot more in the back than coming into the seat. It just feels like they truck's kind of floating around, because it has all that weight in the back, and the front really isn't grabbing as well as it should.Now, as I come up to the slalom course and I start going through the turns, it really just doesn't feel as stable as it should because those front tires aren't grabbing as much. That body really just wants to start leaning even before it starts to turn.If you have your truck set up like ours, where you have a ladder rack, maybe some toolboxes, not to mention all the other equipment that we're going to be putting in it, it is going to put a strain on our rear suspension. You can kind of already tell that it's weighing it down already, and we don't even have it full of everything yet.

This is going to cause quite a bit of problems. Not only are we going to get that rear-end sag, which is putting a lot of strain on a rear suspension, but the front of the vehicle is going to lift up a little bit, causing the headlights to be out of alignment, blinding people when we're going down the road. Not to mention that our tires aren't going to have a good as contact on the ground, so they're going to wear out faster and cause some alignment issues.With our Timbrens in place, we can already look at our wheel well area and notice that it is a little bit higher. They are providing us that extra support, and the back end's not sagging down as much. Because of all those things, our truck's going to be right back where it should be, and ride more like it was from the factory.One thing I do want to mention is that our Timbrens are not going to increase the payload of our truck, and you never want to exceed the manufacturer's recommended weight.Now that we've seen what our Timbrens look like and gone over some of the features, let's show you how to get them installed.To begin our installation, you're going to want to raise the back end of your truck up so that the axle can hang freely.

You're going to want to make sure that you lift it by the frame. Then we're going to come to right above the axle, and we'll find our factory jounce stop. The very bottom, there's going to be a hole, and a bolt's going to be in there, holding it in place. I'm going to take a 13mm socket and an extension, and we're going to remove the jounce stop. We can go ahead and set it aside, because we're not going to be reinstalling it.Now we can take our bracket. One of them should be labeled "left", so it's going to go on the left side. But if it's not, the easiest way to tell which bracket is which is . The ears here are going to go in the inside, and we want the round part of the bracket facing towards the rear. If we had it over on the other side, we're going to know it's not the right bracket, because the flat part is facing towards the rear.Then we're going to take an M10 bolt. This one's going to be the short one in our kit with no shoulder on it, and we're going to grab a lock washer. The easiest way I've found to put these in is if we take a ratcheting wrench and we put our bolt into the wrench, and then feed it through our bracket. That way we have ahold of it, and we can get the bolt started. Just reach in so we can hold the bolt, and then we can start tightening everything up.Again, you just want to make sure those tabs are on the inside of the frame. Now we're going to grab our rubber spring, and we're going to grab one of the long bolts, it's going to have a rather large shoulder on it, and also a large flat washer. Put the washer on the bolt, and then on the bottom of the spring, there's going to be a large opening. We're going to feed the bolt and the washer inside until it'll come out the top. It can be a little tricky. We just want to work it back and forth until we can get the bolt to come out. You can hold it in place with your finger.Then we're going to take our spacer, put it over the top of our spring, and then just by hand, we're going to get this started. You just want to reach in and turn that bolt a few times so that it'll hold the spring to the bracket. Once we make sure that it's going to hold, we can come back with a 17mm socket and ratchet and tighten it up.Because our spring is so much closer, it'd be easier to use a long socket with no extension. It'll reach right into the spring, and we can tighten it up. Our spring is going to have a lower bracket that's going to sit over the axle, so we're going to drop the U-bolts over the axle. There's going to be a small tab that's going to fit in between the leaf spring U-bolts here. It's going to be pushed up against the leaf spring pack.Now we're going to try to get it somewhat centered on the axle so these loops down here are sitting flat to the curve of the axle, here. This'll give us a nice flat surface for our spring to make contact with.On the bottom side where the U-bolts are coming down, we're going to take our saddle clamp . You want to make sure that curve is facing up, so it's going to contour to the axle. Then we're going to slide it in place, and just hold it with your hand for now. Then we're going to take a 3/8 flat washer, put it over one side of our U-bolts, and then take a 3/8 locknut and just put it in. Hand tight for now. We'll do that for both sides.Now I'm going to make sure that my bracket's nice and level, and the top section is contouring to the axle. Then we're going to tighten up the 3/8 nuts with either a 15mm socket or a 9/16 socket. It's important that you alternate going back and forth so it doesn't get in a bind.Again, with either a 15mm or a 9/16" socket, we're going to torque down the nuts on our U-bolts to the specified amount in the instructions. Again, you just want to do a few turns, go to the other side, so you're tightening down evenly.With this side done, we're going to repeat that same process on the other side. On the driver's side, we are going to have all these lines right by the axle. We want to make sure that these lines aren't going to get pinched in between or start rubbing against our spring itself. Since they're not going to stay on their own being pushed over, just going to take a zip tie. I'm going to go around a few of the lines, and go around this vent tube here, and use a zip tie to just pull it over some. That way they're a little bit farther away, but they still have slack to move with our suspension.That'll finish up your look at the Timbren suspension enhancement system for the rear axle, part number TFRTT1504E, on our 2017 Ford F-150.

I was surprised at how easy the OEM ones were to remove and how incredibly east the new ones were to install. I read the reviews and saw that there was more of a jolt when hitting potholes and rough roads. I believe the clearance between the plate and the buffer is about an inch. I have a 32 foot trailer I haul that holds a sub compact tractor, a mini hay baler, mower, rake and hay spears. I was concerned that the weight would damage the springs. So knowing the rougher ride when on bumpy roads, I felt it was the best option that was in my price range! That you so much!!!!! 628212

Installation was easy- did not require raising the truck as with correct socket extensions it’s doable. Would be nice if components had better paint adhesion. Also the u-bolts/brackets did not have any paint at all!! 572267

This is the second time I purchase and install these, the first was for my 2013 F150 and now on my 2017 F150. I towed my 9600lb bumper pull RV with the new 2017 truck before i ordered this second set, just to see if i noticed the difference. I loved the last set but heck, life is about experiences right? Those of you who have these are laughing right now as you know what I'm going to say. HUGE difference, noticed the absence right away. Got home from that camping trip, straight on my computer to order this latest set. As far as I'm concerned this is the best $200 bucks you'll spend. You have extra cushion when it matters most and it doesn't affect your ride at all when you don't. They are very easily to install and you don't have all the extra equipment etc as with an airbag system. I'm not the kind of guy who works on his truck, I don't consider myself mechanical at all yet i didn't have any problems with the installation. The only "issue" i had was when attaching the stop bumper to the metal mount. The screw is just long enough so i could get the tension i needed to get it threaded (the head of the bolt would drop slightly within the socket). I was able to get it threaded by using my index finger to hold the bolt and my ring finger to turn it, just enough to get it started. After that I was fine. As i mentioned, I'm not mechanical so my tool options were limited. Just bring some patience with you and you'll be fine. The instructions are good. As long as I'll be towing a camper, I'll have a set of these on every truck I own. 400940

I owned these for about a year and just recently switched to air bags instead. While the Timbren spring helped level the truck under load, there were other things that I was not satisfied with. One issue was the amount of distance the truck would drop until the Timbren would engage, I would have like to see them take affect sooner. I did not like the ride while empty. When hitting a decent size bump in the road the spring would slam into the stop causing for a very jolting ride. Also while under load and the Timbren was engaged, it made the truck extremely bouncy. Again it did stop the truck from further squatting under heavy load, but the other factors were what made me switch out for air bags, to which I have been very happy with. 565705

Simple install and works very well on my 2015 F150 4x4. The truck feels way more solid while towing and you don't notice the Timbrens while the truck is unloaded unless on a really bumpy road. Overall great product for the price! 538585

I purchased these to help with the poor rear suspension on a 2018 F150 while towing my 27’ camper. They will definitely stiffen up the rear end but in return they make the ride like an Abrams Tank. 663431

Functionally these Timbren Rubber Springs provide additional load capacity and reduce tipping while turning around corners on my F-150 as claimed; however, the set I purchased was overly stiff (I was only hauling 500 additional pounds). Timbren provided a replacement set with lower capacity which helped tremendously; however, it still rides slightly stiff. I wish Timbren or a competitor would provide these rubber springs in different durometers that provide 1000 lb increments to fine tune the suspension - reducing the over stiffness performance. 655944

I have a Ford 150 2015 with trailer package . I put the over loads on because I pull a 20 ft enclosed and a 20 ft open trailers wit Mustangs on . With the enclosed I found that there was a little sag in the rear of the pickup on long travels . Putting the overloads on were a 1 hour job didn't take any thing off the truck just jacked it up and put every thing on . Then found out it rode a little to ruff with out a trailer so I removed the small rubber donut and it rode great . 500030

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Working great. I had read reviews about them being too stiff whem you aren't pulling a trailer, but it seems like they softened up a bit after first putting them on. I felt a few hard jolts going over speed bumps and such the first few days, but now I don't notice them at all when I don't have a trailer attached. They are still improving the ride with a heavy trailer. I'd give 5 stars but my mechanic neighbor had to help me install them because there was something wrong with the bolts that came in the package. It was a year ago and I can't remember the details. Without him I think I could have returned them and gotten a fix and installed them by myself. It's a very simple install when all the parts are in good shape. 549083

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I first put the Timbrens on the rear to help stop bouncing and porpoising on highways and bridge ends when towing. The rears have a gap and do not touch the springs until the truck is loaded, working great and keeping a smooth unloaded ride. The front Timbrens fit snugly and touch all the time. The ride is firm and a bit harsh with my unloaded truck having a snow plow spring option. When my trailer 30 ft trailer is hooked up, the front of the truck is slightly lighter. Towing with the Timbrens is nice and the bounce and rebound porpoising is very controlled. I would like the front Timbrens to be a little softer when the truck is unloaded, but I think these units are a nice add-on for better control, safety, and preventing damages. I had the fronts installed at the shop when rotating tires and a front end alignment. The rears installed easily. 691475

got the product when stated , went on simple enough but used google to really see how things went together. Timbren doesn't give very good instructions with their product wish they would put diagram so as to be able to see how brackets go, but happy so far haven't put load on the truck yet that's coming up with a trip in august with my 30ft camper and truck loaded for trip guess will come back and let you know how the product works after the trip , but etrailer delivered when they said they would thanks will keep you in mind for future purchases. 544811

Over a year, and several heavy loads later, these Timbrens are still going strong. Easily the best addition to the truck and at the lowest cost.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I purchased a used pickup without any jounce bumpers. I ordered these to provide more support rather than going back with stock ones. I pull a 5th wheel and these keep the truck level with less bouncing around and bottoming out when towing. When I'm not towing they sit about an inch or inch and a half about the stops so they do not negatively impact the ride quality. They work as advertised and I'm pleased with them. 653123

After a 3000 mile trip with a 42' fifth wheel on a 2016 Chevrolet single rear wheel short bed 3500HD, I will say they made a difference. They took some of the bounce and the side to side rocking out of the truck. I would definitely put them on my next truck as well. 667565

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Ordered these (6,000 lb Kit) to cure getting too nose high when towing after installing a Bilstein 5100 Level Kit on my 2016 F150 SuperCrew 4x4 (front struts set on max 2.10" setting sitting nearly perfectly level). Tow a 29' overall length travel trailer (~5,500 lbs) and for work we use a 20'x8' enclosed trailer (~9,000 lbs when loaded). Use a WD hitch, but still get the nose up when pulling both. Install was easy. Read through the instructions and watched a video before they came in. Crawled underneath and installed in about 30 minutes after I received them. Didn't remove the spare or the heat shield like the video I watched showed. A lift would have made it easier of course, but can be done in the driveway if you like doing stuff yourself. Used the included spacer and have about a 1" gap, which falls in the advised .5" to 1.5" range from the instructions. I haven't gotten to use them with the work trailer, but I have pulled the travel trailer and they do exactly as advertised, cures the sag, and nose doesn't go up at all. May be slight nose up with the work trailer, but I wouldn't believe it will be like before. Driving while hooked up feels smoother, too, with less body roll/lean in turns. So, overall satisfied with the purchase. The only reason this is getting 4 stars is that, like others have stated, the parts that were painted left a lot to be desired. Very sloppy with some areas that were already flaking off and one part had a spot that was completely missed by paint. The piece that goes underneath the axle to secure the contact plate is not even painted, it's just raw metal. So, I'm curious about what that will look like after one salty winter here in MO. I may find some time before the winter hits and take everything off and do some painting myself, but for $215 you'd kind of think that wouldn't be something to worry about doing with a brand new part. 543563

After 1 year, I’m still very satisfied. Have towed many times with them and the truck stays right at level. This will be something I order for every truck I get in the future. Improves towing without the cost of airbags. I didn’t have to wait more than a few weeks for the rust to appear, though. Had to take everything off and apply a couple coats with some industrial grade Rust-o-leum paint and have been doing good so far. Frustrating to have to do that, but at least I know to do it every time in the future.

Not really happy. They do provide some additional support. However, they interfere significantly with the factory hydraulic self leveling suspension system called Automatic Height Control. Most definitely will not purchase again! 676582

Simple install. It takes longer to put the jack away then install the springs. It would take longer to make toast. The ride after is better than factory new. Great produt and as always great cust. service from etrailer. 350417

this is the second set of Timbren springs I have purchased, the first set was on my Ford Raptor, they took all of the sag and sway out of pulling my boat. I have this set on my 2015 GMC Denali 2500HD, I pull a 42 ft. 5th wheel and the Timbren's take all of the sag and sway out, these are in my opinion the best product I have purchased for my truck. 683687

Works as advertised. Really helps my Lexus GX when towing 6500lbs camper. Especially when going over bumps. Does not effect ride when not towing. 662538

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


TOTALLY AWESOME PRODUCT.....Though I wished I had them when we trailered the hot rod out to New Hampshire last month. We received this item late as it was on back order for far too long. I did get a chance though to put the levelers through their paces when using our 18' lo-boy to haul large limbs, branches and other brush to compost site. The truck did NOT flinch and inch downward as it did WITHOUT the levelers. I liked too that the installation was basically pretty easy. I highly suggest going this way and leaving the air bags for the big truckers. Don't have to fuss with filling or deflating bags or dealing with leaky bags. This is a presto zippo installation and you can play "immediately". 550307


Comments

I couldnt be more happier with this product. Truck is still remaining relatively level, even with the hot rod in the enclosed trailer. Hot rod weighs in at 2200 pounds and nary a between truck and trailer. As in my earlier review, I HIGHLY recommend this product over air bags...so much LESS hassle .

Product was purchased based on mechanics recommendation for a friends F250 being used to tow a thirty foot gooseneck 3 horse trailer with living quarters. Post installation performance was all we hoped for. Service from etrailer, before and after the sale, is what every mail order company should strive to achieve. I will not hesitate to utilize etrailer in the future. They are flagged in my favorites. 324435

2012 Ford F-250, no overload springs. Loaded 24,000 lbs on a 32' gooseneck. Pickup would squat too far. Installed Timbrem rear suspension enhancement and pickup runs almost level and rides great!! All I needed to handle the load. Great product!! Would recommend to anyone looking for overload springs. Installed in 30 minutes!! 165636

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I had trouble with my browser called and spoke with Karen. She took my order. Then turns out I had two orders of the same thing. Karen took the time to call my home and ask is I really wanted two of the same thing. Great company, great customer service. How many companies in today's world would have made the extra effort. This is the second pair of Timbren I have bought. I love them. Used them on a 2010 Silverado, and now on a 2014 Express Van. Not only help the 'bottoming out' effect, but great for stability during towing and when fully loaded. 146117


Comments

After a year I still like them for heavy loads. I have found the bottoming out when hitting a bump with no load painful and uncomfortable. I actually cut two coil off them to allow the normal suspension to work when having no load. They still work for heavy loads. They are not the panacea for suspensions, but they definitely work when you have a heavy load.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I installed these on my 2012 Ford F250 because I have two friends who have them on their trucks and they pull a travel trailer and a fifth wheel camper. I was impressed with the difference it made compared to my truck and camper Parked next to theirs'. I am mechanic and I see no reason why anyone would have trouble installing these them selves. Clean off the Nut and end of bolts before trying to loosen. Spray some WD-40 on the threads. Put on some gloves and use a 15mm wrench to loosen factory nut. Be sure to hold up on the factory bump stop because it has a line up pin that keeps it from turning as you loosen the nut. The driver side is a little more aggravating to get to because of wiring harness but there's plenty of room to use a wrench first then a 3/8" drive rachet and short extension with a good 6point 15mm standard depth socket will speed up removal. Then installing the new parts is a breeze. Just follow directions or etrailer videos on YouTube. Took longer to remove factory bump stomps than to install new ones. Maybe 45 mins total on original ones maybe. Then after preassembly of new ones, it took maybe 20 mins to install completely. Give yourself 1:30 hrs of time and enjoy your truck not sagging around town when loaded. 654107

Fairly simple to install. Did not have to Jack up my 18 f150, but would have probably made it easier. Install was pretty straight forward bolt on operation. I Haven't pulled my 28 ft camper yet. The bump stops I removed were 1/3 the size of the new ones. They should work real well. No noticeable ride difference with no load. Thanks. 641299

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Best available for Kia I wish I would have known about this product sooner. I have a Kia Sedona and there are only 2 suspension aids available. I previously had the Firestone airbags and don't recommend. The bags and compression fittings leak and installations complicated. This was the only other option so I gave it a try. Very glad I did. They do exactly what they say they do. The Sedona doesn't dip nearly as much when I put the trailer on. In fact I had to go to my lower rise hitch so it would sit flat. Ride is solid, but not jarring. I don't really know about the reliability as I've only had them about a week, but it's a very simple concept so I can't imagine problems. They are basically oversized flexible bump stops and have no moving pieces. They seem expensive for what they are, BUT installation is MUCH cheaper than the airbags. It cost me just a bit over a hundred bucks to have them installed at a local service chain (Tuffy). They also are very discrete so your warranty likely won't be called into question. 3579

Product came securely packaged and complete and quick. Took about 45 mins to install. I bought this to try to reduce the 3 1/2 inch sag at the hitch of my Lexus GX460. It did that well. I now only sag 2 inches that I feel is acceptable. The trailer has about 484 lbs weight. The ride doesn't seem affected and towing bounce(porpoising) is gone. Thank you etrailer. 560925

Timbren are working fine. Towing is much more controlled. I am glad i purchased them. I don’t notice any ride difference when running empty.

  • Timbren Suspension Kit Recommendation for 2016 Ford F-150 4x4

  • Things To Consider When Changing from a 3/4 Ton to 1/2 Ton Tow Vehicle
  • There are a few things you need to consider when switching from a 3/4 ton like your 2008 Chevrolet Silverado 2500 to a 1/2 ton like a 2018 Ford F-150. For starters, the 3/4 ton is going to have a stiffer suspension than the 1/2 ton. This means that although the 3/4 ton did not squat while towing your trailer, that's not to say that the 1/2 won't even though it may still have a higher towing capacity. Also, the 3/4 ton will be more geared towards towing while means it likely has upgraded...

  • How To Fix Trailer Bounce When Towing and Suspension Enhancement For 2018 Ford F-150
  • The suspension enhancement options for the 2018 Ford F-150 may help with the porpoising effect that you are experiencing. However, usually porpoising is caused by the trailer weight not being properly distributed. If there is too much weight in the back of the trailer the weight could cause the trailer to bounce.
