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 Front and Rear Suspension Enhancement Systems Review

Speaker 1: Today we're going to be taking a look at the Timbren line of suspension enhancement systems. Any time that we add weight to our vehicle, it's going to put a lot of strain and stress on the suspension, especially if we're towing a heavy camper, trailer, or we have a heavy load in the back.Tends to have the back end squat down, which again, it's going to put that strain and stress on the rear suspension because not only are we asking it to hold up the weight of the vehicle, but everything else that we add on to it. Which that can arise a lot of different issues. The front end is going to be getting pulled off, which will misalign our headlights, and our tires won't have as much contact, so our steering and braking is going to be diminished.But tat;s where timbrens are going to come into play. They're going to provide us that extra support so that when we do have those heavy loads, the back end doesn't sag down quite as much, and it's not putting so much stress on the back end. By doing that, the front end's not going to rise up, which means our headlights will be in line and our tires will have the correct amount of contact and pressure, so our braking and steering isn't affected.

And they're going to do that all while making our ride more comfortable with that extra load.Our timbrens are going to provide us the support we need by replacing our factory jump stops and mounting in between the frame and the axle. Now, yours may look different, so you want to double check inaudible 00:01:20 fit guide for your specific application.Now, each one of our timbrens is going to feature a steel bracket. They're all going to have black, powder coat finish on them to resist that rust and corrosion or any other kind of chemicals that may be on the road. They're going to have a hollow, rubber ayon 00:01:36 spring that's going to take a lot of that pressure and strain off of the rear suspension.Whenever we do load our vehicle down, the space between our frame and our axle is going to get smaller. That's where our spring is going to make contact with the axle, and it's going to start compressing.

Now, they are progressively rated, so if we have a small load or a light load, it's going to have a little soft engagement. But the further it gets compressed, the harder and stiffer it becomes, giving us the support we need with those heavy loads.And since they are rubber, they're going to have a lot of give to them, which means they're going to give us the support we need. But at the same time, they're going to give us some more cushion and absorb some of the road shock as we drive. And since the rear ones here aren't in constant contact with our aXle, it is going to provide us the same ride quality when it's unloaded.Our timbrens are going to work independently from each other from side to side. That way, if we have an off center load, it will help compensate for that, but at the same time, if we take an evasive maneuver or a really sharp turn, this is going to help reduce that body roll and some of that sway feeling that we get going on when we have a lot of added weight.Our timbrens for the rear are going to be a good enhancement for any time you're going to be adding weight to the back of your vehicle, whether it be a heavy trailer, a large load in the back or any other situation where you're adding a lot of weight to the back of your vehicle.Now, timbrens on the front are going to be a little bit different.

They're going to provide us that load-leveling support and make sure the front end doesn't get pushed down too far. However, these typically are going to be in contact all the time, which means it's going to give us that support and help reduce on that body roll all the time, all while absorbing that road shock, giving us a smoother ride.Now, some situations where you'd want that extra support on the front of the vehicle to keep it from getting pushed down too much would be if you have a snow plow or winch, if you flat-tow your vehicle, or if you have any other heavy accessory on the front. This is going to make sure that front end stays where it should be, and again, making sure our tires, braking and steering acts how they should.When comparing the timbrens to other suspension enhancement options like airbags, these are going to be a lot easier to install because we're not going to have to worry about running lines, maintaining air pressure, putting in switches or compressors or any of that. Once these are installed, these are going to be completely maintenance free. However, airbags are going to provide us with a lot more adjustability, whereas our timbrens are not going to have that.That'll finish up your look at the timbrens suspension enhancement systems..

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I am dealing with Timbren. The washer for mounting the rubber spring to the mounting plate clearance hole is too small for the bolt diameter. The washer is not something you can get out without damaging in my opinion. The bolt also will not thread completely into the mounting plate because of poor threads ( not tapped correctly). Galling of bolt if you try to tighten. Very poor QC or inspection at Timbren or wherever. Once again, working eith Timbren on this. Maybe you should check you kits at etrailer!! 704185


Comments

I pulled the kits we have in stock and they check out fine. The washer inside the spring had the same diameter as the spring for the bolt. Could you send in a photo of your kit?

Makes a huge difference in carrying heavy loads. I could tell an immediate difference when I had a full bed, gooseneck load, or a bumper pull load. Highly recommended. I considered air suspension, but did not want to tackle that installation. Literally can install this with a torque wrench and impact wrench. 725228

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


We just took our first trp (towing) with the "Timbrens", today. Our Travel Trailer is about 8,000 lbs so I'm sure that they engaged fully. They have smoothed out the ride considerably and there is a definite lowering of the front end of the truck. I noticed that when just my wife and I ride in the truck, there is no noticeable difference; as they are not engaged. Add 2 more people in the back and now the ride gets a whole lot stiffer, as they probably engage even with this "little" extra weight. It appears that the real gain is when I add a full load of the trailer, extra fuel and other things packed into the bed of the truck. I believe that we made the right decision having these put in, in place of the OEM rubbers. It was a good decision. I recommend them highly if you're going to tow something heavy. 523578

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

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 .

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

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

I put the Timbrens on a 1997 k2500 I haul 2 mobility scooters and travel trailer. With just the scooters and no Timbrens the truck set down about 3/4-1 inch so I installed mine with the 1/2 inch space left. With just scooters it rides firm but not harsh if on dirt road or hitting a hole you will know it with trailer attached it rides great no more rear end of truck bouncing up and down when going over a bridge. Also helps on truck lean when going in curves has been a great product for me 513079

I have installed and used the Timbrens on my 2015 F350 dually with my 5th wheel Keystone Fusion RV for a year now. i have to say that the Timrens are not only easy to install but make the ride of my truck excellent not only on the highway but back roads as well that includes very twisty turns. Timbrens keep my truck level and i don't have to ever worry about airbag air pressure. i have owned airbags before and never again will i ever buy or use them. When you don't have a load in the bed or your RV hooked up the Timbrens ride above then axles.. Best investment for towing period! 264475

I am impressed with the timkens. Got a 2009 GMC 2500 hd and Western 8.5' v plow. Nose dive was an understatement before. However I put a 2" leveling kit and installed the timkens at the same time. One of them made my truck ride horrible. Probably the leveling kit from the torsion bars being turned in. I do notice tho that empty going over a jarring bump you can feel the timkens hitting hard. But with a plow on the truck it is the way to go. After this winter I'm gonna take them off and put stok back on for the summer. It's one bolt to replace them install was a piece of cake. 592401

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

It was very easy to order this item from Etrailer. The item was delivered earlier than expected in strong packaging. Now for the Springs. I chose these because of the no drill install and reading a lot of reviews. I placed the springs on the rear axle of my 2018 Georgetown GT5 on the Ford F53 20,500lb chassis. It took around 20 min on my back but was easier than expected and I am 74. I have driven 1200 miles on the springs and I am more than happy with them, worth every penny. Side wind and passing trucks was almost eliminated, almost. 643899

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Have not towed our fifth wheel with these installed yet which was the main reason for the purchase. Towed a dump trailer and the added stability was definitely noted. With my truck loaded as usual with several hundreds of pounds of gear (two tool boxes, wood dunnage for leveling camper, ladder, B&W Companion fifth wheel hitch/Turnover ball, floor jack, tire inflator, jumper cables, screw gun kit, two traffic cones, brooms, squeegee - you get the idea!) the Timbrens are in contact with the bumper bars on the axle setup. Was hoping that the springs would not be in contact during normal daily driving but the stiffening of the ride is more than tolerable. I did not install the additional spacers as I could tell it would just add more weight to the Timbrens when loaded for daily driving. I'm sure if my truck bed was truly empty I would be off of the Timbrens. As for the five star rating without using these for the primary purpose I must say that is all on etrailer. They were great to deal with, answered a question I had very well and the shipping was extremely fast. 421213

Received the product promptly. Exactly what I needed .... decided on this instead of air bags since I only tow a boat. 37180

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.

The product worked great and was very easy to install. The delivery took a little bit longer than I had hoped for, however everything worked out fine. I would highly recommend this product for towing, or if you're putting your vehicle under any kind of a load. E Trailer was fantastic! 561603

  • Availability of Air Helper Springs on a 2014 Ford F-350 Cap and Chassis 4X4
  • We carry a couple different options for suspension enhancement for your 2014 Ford F-350 Cab and Chassis. Unfortunately, none of them are of the air spring variety. For your model, I recommend the Timbren Rear Enhancement System. Timbren offers two different weight capacities for the this vehicle. A standard duty model, # TUR350, and a heavy duty model, # TFR350TTCC. The standard duty springs,# TUR350, are rated up to 6,000 lbs and are of the jounce bump style. The Timbren system...

  • Suspension Enhancement Recommendation for 1999 Ford F-350 with Curt Gooseneck
  • We have suspension enhancement that fits your 1999 Ford F-350 but none of the air bag kits will work since none of them will fit with an in-bed mounted fifth wheel rail kit. The most popular option will be the Timbren kit part # TUR350 which will work with the Curt hitch part # C60720.

  • Suspension Enhancement for a 2010 Ford F-350 with 6 Inch Lift
  • Since there are no 6 inch spacers to use with the Timbren springs # TUR350 using them on a truck with a 6 inch lift like your 2010 Ford F-350 would render the springs useless. There are other options though. You could use Firestone Ride-Rite Air Helper Springs # F2550 if your custom 5th wheel brackets have the hole in the center of them (above the centerline of the factory bump stops). Otherwise that hole will have to be drilled which is generally not an accepted practice because it voids...

  • Timbren Suspension Enhancement Recommendation for 2000 Chevy Express 3500 Van
  • Timbrens do not make ride qualities softer unless the vehicle is bottoming out it's suspension. You said it's hard hitting so that makes me think that the suspension is bottom out and a Timbren would help give more support to prevent that. For that you would want the Timbren part # TUR350 for your 2000 Chevy Express 3500 van.

  • Recommended 5th Wheel Hitch and Rear Suspension Enhancements for a 1999 Ford F-350
  • For a 5th wheel hitch compatible with your 1999 Ford F-350 I recommend going with the Demco Hijacker UMS Double Pivot 5th Wheel Trailer Hitch part # DM8550032 in addition to the Underbed Rail and Installation Kit for Demco Hijacker UMS 5th Wheel and Gooseneck Trailer Hitches part # DM8551000. The Demco Hijacker is an excellent 5th wheel hitch rated for weight capacities up to 21,000 lbs. The rail free designed allows for full access to truck bed when the hitch is removed. The wraparound...

  • Recommended Suspension Enhancement for 1998 Dodge 3500 Dually with Flat Bed
  • I can't give you the specific number of inches from the bed to the top of the tire, but I don't suggest having the flatbed lower than the top of the frame at the wheel well. To minimize squat and keep your wheels from impact with the flat bed, I recommend the Timbren Rear Suspension Enhancement System # TUR350. These springs will give you load support and minimize body roll. They will help your truck when under load from your 5th wheel or any other load.

  • Timbren Rear Suspension for 2006 Chevy Express Van
  • It actually really depends on what type of bumpstops you have on your 2006 Chevy Express 3500. You can simply choose from the following: Van 3,600 lb Capacity - # TGMRG35 Motorhome 3,600 lb with 1-Bolt Bracket - # TGMRG30 Motorhome 6,000 lb with 1-Bolt Bracket - # TGMRG30LB Motorhome 6,000 lb with 2-Bolt Bracket - # TGMRG30PL The part # TUR350 that you mentioned is a universal kit which will fit but it isn't a custom fit like the other options so I recommend using one of the custom...

  • Suspension Enhancement That Fits 2001 Dodge Ram 3500 that Has B and W Gooseneck Hitch
  • I have a great suspension enhancement solution for your 2001 Dodge Ram 3500 that has a B and W Turnoverball gooseneck hitch # BWGNRK1394 installed but none of the air bag kits fit since the brackets interfere with the gooseneck hitch. So instead your best option is the Timbren kit part # TUR350 which fits your truck, gives you the same support as the air bag kits, and requires less maintenance since you install it once and it never needs to be monitored or adjusted. It's a much simpler...
