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..

I have had these installed for a year now and they are great!! Installation was very easy, instructs were clear and easy to follow. I have towed our 5th wheel numerous times and it makes a big difference - the truck handles well and stays level when loaded. No air lines or air pumps to mess with - I don't even know they are there when I am not towing. I would highly recommend these. 282662

Talked to Cathy T who was very friendly and was able to answer my questions and concerns( went into this being skeptical) Cathy assured me that etrailer was a customer orientated company so decided to take a shot, recieved product 1 day earlier than expected which was a nice surprise,as far as installation it was as advertised took less than 30min and was very easy (tip run bolt on open slotted end (back)most of the way in then slide in it will make it easier to tighten bolt) have not towed 5er to see how they actually work did raise the rear of truck 08 ram2500 td did not end up with any clearance but it does say in instructions that medium and heavy duty trucks will stay in contact feel like they will do the job. Will definitely recommend and make further orders from etrailer thanks 222723

Ken have not had a chance to tow 5er on the road yet,I did have to move it in the storage lot from one spot to another and am impressed that my truck stayed level I looked at the timbrens with the 5er hooked up and they were compressed some should have taken pic the tongue weight according to the website is aroond 1800 its a montana 3400rl hope this helps some, will update after towing waiting to mount new tires also bought from etrailer the provider G rated and has an L speed rating tire they are definitely heavy duty trailer tires and just from looking at them and picking up would say they are a good tire after some mileage will be the true test

Easy to install, arrived early got to like that. These units sit approx. 1 inch from the axle so after loading my 5th wheel, Im expecting a front lift of no more that 1 inch compared to the 2.5 I had on my last camping trip. Only giving 4 stars until after I put these to the test. Dave. 652687

I have driven cross country a number of times with my 2003 Dodge Ram 1500 since installing for my 10000GVW gooseneck trailer. Has leveled my truck when pulling. Only drawback is the ride is a little stiffer when unloaded, but is a small sacrifice 633133

Product works. Basically these are axle bump stops with compressability . When installing set the gap to about 1.5 inches. Too small of a gap and you will get a stiff bump when the springs flex to close this gap when lightly loaded. Under heavy load the gap is closed and the Timbrens assist the springs. They are fairly stiff and limit both roll and bounce. Not as good as air bags,but much simpler. I found adding an extra leaf in the spring bundle made a best compliment to the Timbrens as the original rear leaf springs on my 07 Ram wer a bit too flexible for a heavy (1000 lbs tongue) weight. This is the simple solution; if you want total control and variable ride settings between heavy and lighter, then air bags with onboard compressor and in cockpit controller are better (at the cost of $$$ and complications) . Also i think the Timbrens are as good or better in heavy loaded "ROLL" as they are both in contact in heavy loaded conditions and quite stiff. Consider also your rear tire selection when towing heavy (6K+); you should choose "E" rated tires 80 psi max, but run at 50/60 psi lightly loaded. The "E" rated tires will dramatically reduce Sway. 589151

Shipped quickly, installed in approx 1hr. for both sides, didn't have to remove rear wheels. Just jack truck up from frame so axle will drop down and give enough room to remove old bumper stop, and install new springs. Have not tried yet under a load, taking a 3k mi trip in a couple of weeks w/vintage airstream, should know by the time I get back home how they will work. DO PUT SAFETY STANDS UNDER YOUR TRUCK, SINCE YOU WILL BE WORKING BETWEEN THE REAR TIRE AND THE TRUCK BED. 542194

I have a 2005 Dodge 2500 5.7 hemi. I installed these in less then 30 Min. I pull a 36' camper with a hitch weight of 1820 lbs. Without these my truck sagged about 3 to 3.5", now I only see about a 1.5 to 2" sag. Truck is level while pulling. I can take 55 mile corners without feeling steering wheel fatigue. Keeps everything in sync. Love the way it handles the bumps as well. I will not ever have another truck without these!! love them! My son had his company install these in his Ford work van as he carries a lot of weight as well. He also swears by them. 463403

After receiving item in mail all pieces were in the Box. I am by no means mechanically inclined and usually have a lot of problems but had these installed On my 2012 Dodge ram in about 35 minutes. Before hooking up to my 5th wheel RV measured 40 and a 1/2 inches from ground to top a will well in the rear and 38 and a 1/2 inches from ground to top will well in the front. After dropping 5th wheel on to truck remeasured and had 40" in the rear and the front remained the same. Ride was excellent and no bounce. Very very good product and I am very pleased with going with these instead of airbags. Would recommend them to anybody. 460715

Easy to install on my 2009Dodge Ram 2500. I bolted the rubber to the bracket then bolted the bracket to the truck. I have one inch of clearance without using the spacer. Truck rides a little rougher. There is a significant reduction in lean when cornering while towing. Good product- recommended. 438958

I have a 5th wheel camper with a pin weight of approx 1800 lbs. It made the rear of my 3/4 ton pickup squat more than I thought it would. After much research, I decided to try these. They have excellent ratings everywhere I look. Guys (and gals) rave about them in the towing forums that I frequent. Delivery from etrailer was fast. I was able to install them in about 20 minutes flat. HINT - I sprayed the nuts and bolts that fastened the original bumps stops to the frame several days before expected delivery with PB Blaster to make removal a breeze. These along with some new heavy duty shocks and my truck is towing the 5th wheel level and like a boss. 436125

Just finished installing my Timbren RSE system. Install was easy and went very well. I had both of them in place in 60 minutes. Would have gone faster if the instructions would have been clearer about assembly of the rubber suspension unit to the mounting plate. The pre-tapped bolt hole in the mounting plate is similar to a lock nut and the bolt does not easily turn, even with a half inch drive. You will have to lock the plate into a vice in order to turn the bolt until it locks. There is a lot of resistance but keep turning until the bolt locks up. Other than that, the unit easily replaces the factory bumpers. Took the truck for a test drive and couldn't believe the ride, and this is without the trailer hooked up. Can't wait to hook up the fiver and check out the new suspension. 347358


Comments

After a full summer of pulling my 5th wheel trailer I can factually say the ride of my truck dramatically improved! My wife noticed the difference too and commented on how much smoother everything feels. Im also convinced the smoother ride will reduce wear and tear on the springs, shocks and axel. The Timbren RSE should be standard on all trucks. Buy this product and you wont be disappointed.

The Timbren set for my 03 Dodge Ram really helped my older suspension, that is also a work truck. I was very satisfied and had great feel when towing our 26' travel trailer.

I put these on a 2003 Ram 2500 4x4 to take the sag out of the rear and smooth out the ride towing my new 5th wheel toy hauler. The Timbrens did just that, made for a lot nicer towing experience. Leveled the truck and took the bounce out. When I'm not towing with only one inch clearence between the Timbrens and the axle you can tell they are there on the rougher roads but most of the time you won't notice any ride difference. etrailer was great, and fast shipping. 223555

Left side went together easy. Right side, not so much. The nut welded to the metal bracket was not perfectly centered on the hole through the bracket, making the bolt want to cross thread. I had to use a dremel to remove some of the bracket material so that the bolt would go in straight. 215789

Bought these as a way of reducing the 3" sag I get when dropping the 3000lb 5th wheel hitch in the back of my 2012 Ram 3500 SRW 2WD Fairly simple job to fit. I am a tall skinny guy so did not need to jack up the truck. Bump stops came off easy. The slots in the Timbren brackets could do with being 1/4" longer, I had the brackets as far forward as they would go and the Timbrens are only just central over the axle. The bolts at the rear of the bracket (the open sloted end) are tricky to get at (need a closed or open ended wrench) and if you have a 5th wheel hitch mounted to the frame close by (like I did) then you have even less room. Tip: Put the rear mounting bolts in first and slide the Timbren bracket in, that way you only have to cinch the bolt up. Did not need the spacer and have about 3/4" clearance unloaded and do not notice any change in the ride unloaded. Have not yet hooked up the trailer so can't yet comment on how much the sag is reduced. 155106

Great Product. Easy install. Only two areas to improve- They should include a few different sizes of spaces to account for variations in suspension height. The included spacer put the rubber too close to the axle and without the space its just a tad bit too far away. It will work though. Also the rear mounting bolt needs to be pit on with a wrench instead of a socket so its hard to properly torque. Other than those minor issues they work great hauling my gooseneck. 80841

Since you have a 4 inch lift most likely you have a suspension lift and you would need a total of 8 of the part # A25723-90AH00 to make up for the additional space. These are 1 inch spacers and you would need 4 for each side. You would need to provide a longer bolt too as we don't carry that. If your lift is a body lift instead then...

  • Which Timbren Rear Axle Suspension Kit Fits 2014 Dodge Ram 2500 Laramie With HD Rear Coil Springs
  • The Timbren Rear Axle Suspension Kit you referenced, part # TDR2500CA, does not come up in our fit guide for your 2014 Ram 2500 Laramie. This kit is specified for Ram 2500s up through the 2013 model year. According to my contact at Timbren the correct kit for your 2500 Laramie is their new kit # TDR2500D. If your application is for a constant load (a camper or welder in the truck at all times) then you could use the # TDRTT3500D.

  • Comparing The Air Lift LoadLifter vs Timbren Rear Suspension Enhancement Systems
  • For your 2012 Ram 2500, you are correct that either suspension enhancement system will work. However there are major differences between them functionally. The Timbren system # TDR2500CA is a very solid jounce spring. It is a strong Aeon hollow rubber spring that is a very easy installation. It is not adjustable, and there is no maintenance. The only down side to these is that they can engage on large bumps when the truck is unloaded. This gives you a decent kick because the springs...

  • Suspension Enhancement for a 2004 Dodge Ram 2500 4x4 and In-Bed Camper
  • You would benefit from some suspension enhancement on your 2004 Dodge Ram and in-bed camper. However, you would not need 2 separate systems. One would be sufficient. Since a camper is pretty much a static load (does not vary greatly in size or shape) going with rubber springs or leaf springs would be the way to go. My top choice is a Timbren system, # TDR2500CA. These springs are going to help stabilize and level the truck, reduce road shock and side to side roll. They have a high 6,000...

  • Which Timbren Kit for 2004 Dodge Ram 2500 Towing 12.5k Trailer
  • For your 2004 Dodge Ram 2500 I would recommend the Timbren kit part # TDR2500CA which will provide you with an additional 6,000 lbs of support to the rear suspension. The heavy duty kit part # TDRTT3500D that you also referenced is a fit for your truck but it's going to be overkill for your truck and would give you a harsh ride. This kit should really only be used on trucks that will be at their towing capacity most of the time. The additional support of the lighter duty kit will be...

  • Is it Safe to Use Timbren Suspension Kit on a 2004 Dodge Ram 4x4 when Towing a 5th Wheel Trailer
  • Using the Timbren rear suspension enhancement system on your 2004 Dodge Ram 1500 4x4 would definitely be safe and would be a good idea to help the suspension of your truck perform better and last longer. The Timbren springs will also help keep the back of your truck from sagging as much which will help with stopping and tire wear. For your specific truck the correct Timbren kit is # TDR2500CA. The kit you referenced is for newer Dodge trucks and is not designed for the 2004 model. I...

  • Recommendation for Suspesion Enhancement Compatible with a Gooseneck Trailer Hitch, 2006 Dodge Ram
  • In order to determine if the Timbren Vehicle Suspension, # TDR2500CA, and the B and W gooseneck hitch you have installed will interfere with each other, you will need to take a look at the installation details, linked below, and the video showing installation on a similar truck to see if any of the same attachment points are used. Based on the video and instructions, to me it seems unlikely but possible that the two will interfere with each other. Also, these springs are designed for...

  • Recommended Timbren Rear Suspension Enhancement System for a 2008 Dodge Ram 1500 Quad Cab
  • For the rear of your 2008 Dodge Ram 1500 two wheel drive quad cab, the Timbren Rear Suspension Enhancement System part # TDR1525H4 would be correct for you. However, if you have the mega cab model then you would want part # TDR2500CA. Both the mega cab and quad cab models have 4 doors but the mega cab model has about 12" of extra cab space behind the rear doors whereas the quad cab models do not have the added space.

  • What Front Axle Suspension Kit Fits 2006 Dodge Ram 1500 2 X 4 Mega Cab
  • The SuperCoils Custom Heavy-Duty Front-End Suspension Coils you referenced, part # SSC-22, fit a range of model years of the Ram 2500 and 3500 series, but not the 1500. For your 2006 Ram 1500 2 X 4 Mega Cab we do offer one front axle kit from Timbren, part # TDDF974A. This kit consists of two Aeon hollow rubber springs that sit above the axle. These help to stabilize and level the truck and provide a more comfortable ride by absorbing road shock. They provide progressive resistance...

  • Recommended Suspension Enhancement to Improve Ride and Sag on 2012 Ram 2500
  • Since one of your goals is to reduce sag I suggest the Timbren system. The TorkLift StableLoad # TLA7311 is mainly for creating smoother ride and to avoid sway and body roll. The Timbren springs will help with sag while towing and won't affect the ride of your 2012 Ram 2500 when it's not loaded. They become more rigid as the load increases to help prevent the truck from sagging. They also work independently to help with uneven loads that improves the overall ride and helps body roll,...

  • Which Timbren Rear Suspension Enhancement for 2008 Dodge Ram 1500 Quad Cab 2WD
  • Mega Cab is how Dodge/Ram refers to its largest 4 door cab. Because the bed is different, certain accessories won't work with the Mega Cab vehicles. All this can get pretty confusing. For a 1500 series Mega Cab 2 WD, you'd use part # TDR2500CA For a 1500 series Crew Cab or Quad Cab 2 WD, you'd use part # TDR1525H4 I've provided you with a photo showing the different cab sizes, hopefully that will make things a bit clearer for you. I'm sorry for the confusion.

  • Suspension Enhancement for a 2014 Ram 2500 with Rear Coil Springs
  • Air Lift suspension enhancement kit # AL88289 will fit your 2014 Ram 2500 with coil spring rear suspension. You can also use Timbren springs, # TDR2500CA. I have linked a video showing installation of this kit for you, a link to the instructions, and a link to our help article on Timbren springs for you to view. The great thing about Timbren springs is that you do not have to add or remove air all the time, there is no maintenance, and they still work independently side to side.

  • Parts Included in Timbren Rear Suspension Enhancement System TDR2500CA
  • The Timbren Rear Suspension Enhancement System # TDR2500CA includes the jounce springs, mounting brackets, hardware and two 1-inch spacers as shown in the linked photo. Please note this kit is NOT a fit for your 2016 Ram 2500; it fits various Ram pickups up to the 2013 model year. I did go to the warehouse to measure the springs themselves; they are 5-inches tall and 3-inches in diameter at the top and bottom. For your 2016 Ram 2500 the Timbren rear-axle kits we offer are shown on the...

  • Recommended Suspension System For 2006 Dodge Ram 2500 With 2 Inch Lift
  • When installing a suspension enhancement kit like part # TDR2500CA on the rear of your truck you need between 1/2 to 1-1/2 inches gap between the spring and the contact point on the axle. There are two 1-inch spacers included with the # TDR2500CA if needed. If additional spacers are needed you can use part # A25723-90AH00. These are sold separately. For your 2-wheel drive the front suspension system you need is part # TDDF974A. The suspension enhancement system you came from, part...

  • Timbren Rear Suspension Enhancement System for a 2012 Ram 2WD Regular Cab
  • If your 2012 Ram is a 1500 model, I recommend the Timbren Rear Suspension Enhancement, # TDR1500DS. These springs have a 6,000 lb weight capacity and can be installed on trucks with or without overload springs and you do not need to install spacers. The weight capacity of these springs is more than enough to support your veterinary box in your bed. These springs work well with consistent loads. The Timbren springs, # TDR1500DQ, that you referenced were designed for the crew and quad...

  • Recommended Suspension Enhancement System For 2006 Dodge Ram Pickup
  • The helper bags are usually installed in place of the jounce bumpers on a vehicle and do not feature the air bags that require inflating. They become more rigid as weight is added to the vehicle and do not affect the ride of the vehicle when no load is added. If you are always carrying the same type load these would be more economical and maybe a better fit for you. An air suspension system is designed to allow you to adjust the amount of air you put in the air bags depending on the...

  • Does Timbren Kit for 2004 Dodge Ram Increase Towing Capacity
  • The Timbren kit part # TDR2500CA which you referenced has a capacity of 6,000 lbs as a pair. They are not rated at 6,000 lbs per spring. This does not increase your truck's overall towing capacity. Basically it gives you more suspension support to allow you to carry the capacity of your truck in a safer way. Towing capacities are more than just suspension. You also have to consider the engine's power, transmission strength, frame strength, braking power etc.

If you have the Power Wagon version then the maximum towing capacity is 10,200 lbs.

  • Fifth Wheel Trailer Hitch and Suspension Enhancement for a 2012 Dodge Ram SLT Crew Cab Short Bed
  • For a 5th wheel hitch I recommend going with a 16K Reese round tube slider, # RP30075. The round tube slider offers the most travel, 12 inches, for more clearance when making tight turns. For an installation kit, you can use # RP30035-186. The Firestone air spring system, # F2299, that you referenced installs on the bottom and inside of the frame rails, so there should be no interference issues with a 5th wheel installation kit.

  • There are a few things to consider when purchasing suspension enhancement for towing a fifth wheel trailer. The Bilstein shocks will certainly help, but it also does not hurt to add suspension enhancement like Timbren springs or Firestone air bags either. They will reduce sag, improve stability and prolong the life of your stock suspension. Timbren and Firestone make excellent products. We use Timbren springs on our Ram 2500 when towing our fifth wheel trailer and they do an excellent...

  • Timbren Suspension Enhancement Recommendation for 2005 Dodge Ram 2500
  • I really like the Timbrens and they have a better warranty than the SumoSprings so for your 2005 Dodge Ram 2500 the part # TDR2500CA would be a great option. If the leveling kit you have was a body lift you would be fine with just the Timbren. If instead it is a suspension lift you would want the # A25723-90AH00 for inch of a lift that you have. So you would need a total of 4 of these.
