Reduced axle sag with Timbren suspension enhancement

Just like the rear of your GMC Sierra will sag under the weight of a fully loaded bed, the front of your vehicle will sag when under the burden of heavy equipment such as a snowplow. In this case, the front axle is handling not only the weight of the equipment, but also more of the vehicle's weight. Overall GMC Sierra 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.


Install diagrams of Timbren hollow rubber springs

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above your front axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down so that the bottom of each spring touches the axle. Because each spring is making constant contact with the axle, it is always working to cushion and support your factory suspension.


Animation of a standard Timbren rubber spring

Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape increases resistance, stiffening the suspension and keeping your GMC Sierra 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 GMC Sierra. 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're carrying off-center loads.

A snowplow mounted to the front of the truck will require extra suspension support for the front axle.

Timbren's Suspension Enhancement System will help raise the front end of your GMC Sierra when you're using heavy equipment like a snowplow. This ensures that your headlight beams will be pointed in the right direction and tire wear will be reduced. If the plow is off-center or has an extension, the springs will automatically compensate for this as well.

An empty truck on a bumpy road without Timbren

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. 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. More elasticity allows for a more comfortable ride because the rubber has more travel.

Video Transcript for Timbren Vehicle Suspension TGMFK25S Review

Today we're going to review part number TGMFK25S. This is the Timbren Front Suspension Enhancement System. This is a custom fit part number, this is designed to fit the Chevrolet and GMC vehicles starting in 1996. What I would recommend since there's many vehicles it will fit on, I would recommend to go to our website and on the Use Our Fit guide and put your year and model vehicle and that will show you if this part will work for your application. This kit will improve your suspension and handling, prevents body roll with improved weight distribution. It does stabilize the vehicle for better handling of heavy loads. It does adjust progressively to road and the load so you always have a smooth comfortable ride and it does provide additional support as needed.

It does allow the spring ample movement while at the same time providing cushioning for light loads. It does increase the stability and gives you great performance while cornering, swerving or hauling large loads. This does take the brunt of the bumps in the rough loads and it does extend the life of your vehicle's suspension. You do have to make sure, though, it is designed to work with a suspension system that is in good working order and this system does not require any air hoses, compressors or manual adjustments. This part includes everything shown here on the table. It includes these two Aeon hollow rubber springs. It includes these specific brackets and the hardware for simple installation.

When you do install these, it comes with a nice set of instructions that are pretty detailed. These will replace the axle bump stops on your frame, there's no drilling required. The capacity on these is 14,000 pounds but you do need to remember you do not exceed the vehicle's weight carrying capacity. Again, as I mentioned earlier, these are designed to work with a suspension system that is in good working order. This does come with a limited lifetime warranty. That should do it for the review of part number TGMFK25S.

These are the Timbren Front Suspension Enhancement System. .

Timbren SES heavy duty jounce bumpers dramatically improved the ride of my Chevy 2500HD and it drops only a very small amount when I hoist the plow. Less than 1/2" dropbin ride height with the plow raised. Yet the riee is not harsh. Excellent product, wish I knew about it years ago. 165956

this is the 3rd replacement of bump stops for my 99 chevy 3/4 HD 4x4. Two were OEM , and one an after market ( lasted a week ! ). I am impressed that the Timbren bump stops are well made and were a direct fit. The truck sits about an inch higher in the front end and best of all the ride is smoother . the truck also has new up graded shocks and the over all condition of the suspension is very sound. the shocks were installed prior to these new bump stops. I would give 5 stars however I am waiting this out to see what the Timbren bump stops are capable of in a year from know. my truck spends most of its time on road not off road . 254821


Comments

I would buy again . these are worth 5 stars.

Installed this on my 2005 Silverado 2500HD with the 8.1l engine. Easy 1.5 hour install with hand tools. Raised front of truck about 1" with constant contact with rubber. I'm installing a Boss V Snow Plow and a Truck bed Camper ( for Summer) and needed the extra weight capacity without the suspension sag. Ride quality degraded some, but is not objectionable. Ride is OK for a truck. This is a better solution than changing to stiffer torsion bars or cranking up the stock bars for my application. 589250

Highly recommend spending the money. My last pickup I bought Sumo Spring rubber stops and they seemed squishy to me, where these are hard and hold up very well. Holds my Boss V-XT 8'2" up where it needs to be. Don't go cheap! You'll regret it! 319272

My 03' Chevy Silverado really benefited from the installation of the Timbren bushings. Shipping was fast the instructions from E-trailer were very helpful and made it easy to DIY. The front end of the truck seemed to be sagging especially when the plow was raised even with 600 lbs of ballast. The front end was raised up about 3/4" after the install and the ride quality is greatly improved overall. I cannot hardly wait to try them with the plow. I would highly recommend Timbren bushings to anybody with a higher mileage vehicle like mine 160,000. 302726

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Great product and installs easily. I did not use the spacer, so this allows the stock suspension about 1-1/2" of travel before contacting the Timbren units. I tow a 16K fifth wheel and the Timbren's handle this load very well. You can see the compression marking on the lower side of the Timbren when the trailer is hooked up to the truck. Just enough contact to keep the truck at a level stance. My stock "bump stops" were starting to fall apart from age and wear/tear. These Timbrens now add an extra level of suspension that makes the truck feel much more in control when pulling the fifth wheel. 574936

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Rear suspension pads work great. Ride is still like factory with no load unless driving over a big bump at high speed. When towing a 32 foot travel trailer the sag in back end of truck is greatly reduced with a lot more control. Easy to install. The downside is when truck is full with passengers and not towing anything the added weight makes the ride rougher. Shipped on time. 575558

My 2015 F-350 dually would always squat when I’d hook up my fifth wheel. Towed it for the first time since purchase and install and the truck is nice and level. The ride is better also and after driving a bit without the camper I don’t really notice them. I love the simplicity of these over airbags and imagine they won’t be needing any maintenance or replacement anytime soon. Great simple solution. Not so easy for an old fat guy to install laying under the truck in the driveway but I managed! 442491


Comments

They work. It is nice towing nice and level now. The ride with the load on is good and smooth and very stable. I am still very happy I went them. Put them on and forget about them, no maintenance and no worries.

Product works great, 100% better when I’m towing. I have absolutely no complaints about the product. The only issue I had was the package was short 2 washers that the instructions called for. I didn’t contact the company, because I have Spare washers and it was a lot easier to use what I have versus contacting them. 574500

Just what the truck asked for... I’m a Farrier, I carry a full workshop in the bed of my truck 24/7. I drive a 2001 Toyota Tacoma 4x4. After a couple months I redid the entire front and rear suspension and added heavy duty rear leafs. After about a year of driving and also adding more tools the truck began to sag a little bit. Ofcourse, the first thing anyone suggested was “airbags” but they didn’t know the use of the truck or where the truck goes from day to day. Being a Farrier, I travel on everything from paved freeways to down and dirty “4lo” back roads. I needed a maintenance and care free system that would allow for over extension and hold the extra weight of my tools and sometimes even a trailer. I did a ton of research and even talked to the Technician Staff at each company. I ultimately decided to go with Timbren SES Kit. It’s easy to install, maintenance free, free floating, and has the best warranty in it’s category. Since I have a custom setup (Ubolt Flip Kit from AllProOffroad) I had to design and build some landing pads to allow for an “interference free” contact with my system. After the first day of working, I am COMPLETELY satisfied with its performance and how my truck feels and drives. As for ”Etrailer” I am very happy with all the information and excellent customer service. I received my parts 2 days before it’s orignal date which makes me super Happy! 570702

These are an awesome suspension up grade. Great for beefing up a half ton. I installed front and rear timbrens on my 02 tundra and im carrying 2000 lbs. Level, no suspension sag and have had 2800 lbs on still handled ok with no droop. Down side is they ride really rough if you do alot of dirt road / off-road driving. I don't recommend those load weiights with 6 ply tires move up to 10 ply. 573504

They have performed as described. When hooked to my gooseneck trailer truck squat is minimal, and best part is hassle free install and forget. I have been driving empty and unhooked without any notice to ride difference unless I hit a bad pothole. I would recommend them to anyone looking into option of airbags. 573990

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


A year ago, I added Timbrens to my '09 F350 to help carry a '09 Lance 915 camper. Since my truck is a CC LB diesel model, the truck payload and loaded weight of my camper are similar. I found the Timbrens a cost effective way to limit the suspension sag and improve truck/camper sway. When unloaded, I rarely notice the Timbrens as they are ~1.5" away from the spring pack stop and only engage on large bumps. I also like the maintenance free aspect of Timbrens. To further enhance the loaded ride, I am replacing the thin factory contact pads on my overload springs with larger ones. I found that adding the Timbrens limited suspension travel such that it prevented adequate overload spring engagement with the factory pads. The replacement overload pads from Torklift and Supersprings are 3" (too much IMO as they contact the overload spring nearly all the time making for a rough ride). I am cutting down a set of Superstops to ~1.5 - 2" for the right amount of overload spring contact and Timbren engagement but still maintaining unloaded ride quality. 570372

Great quality products at a great price. Fast shipping and delivery. Easy installation with the included instructIon sheets. The Timbren SES provides a much smoother ride with regular shocks than the previous setup of coil over shocks alone. The 7 and 4 pole trailer connector provides the flexibilty to pull my teardrop trailer which has brakes and a 7-way plug or my utility trailer which has a flat 4-way plug without adapters. Fantastic customer service. Etrailer.com has a great selection of products for your vehicle and traveling needs. 570293

STILL GREAT! Been on 2 road trips totaling 35,000 miles, to include The Dalton Highway to the North Slope and Deadhorse and across the plains states at 90 MPH and they have worked beautifully. Best investment I have made for my truck. P.S. Have a truck camper so all the weight is on the truck, not just the tongue weight.

Very easy to install. Works great. Didn’t seem to affect my ride. Levels up my rig when I put the camper on or hook up to a trailer or piece of equipment. Love it and would highly recommend it. 570299


Comments

Timbren suspension systems wont have a whole lot of effect on vehicle ride except during cornering or when the vehicle is under load. Once a load is applied to the suspension, either from cargo or from the tongue or pin weight of a trailer, the suspension will compress enough for the Timbren Aeon springs to contact the axle.

The Timbrens are great. I have not had the truck with a full load yet but I anticipate they will help bring the truck back to level. The install went well but we were not able to use the additional spacer even with the longer bolts. We were not able to put enough pressure on the bolt to get the nut started. I don’t believe I will need the spacers so it should be ok. The directions didn’t include the amount of torque that was needed so I sent e-trailer an email. They checked with Timbren and the torque is 1/4 turn after they are tight. Ive attached some pictures of the completed install. 566262

Caveat: I just installed these and have only road-tested unloaded. 1. As usual, etrailer filled my order quickly and accurately. 2. Installation was as easy as advertised. I did not have use of a lift and did it in my driveway. I did not remove the tires. I lifted one side at a time, blocked all other wheels and used a jack stand to back up my bottle jack. Hint #1: the higher you lift the truck, the more clearance you will have to work over the tire and insert your socket into the jounce stop and Aeron spring. Hint#2: The hole in the bottom of the factory jounce stop is small. Use a 3/8" drive 10mm socket. My 1/2" 10mm socket wouldn't go in the hole. 3. Installed, I ended up with a little more than 3/4" clearance. My road-test showed me that the Timbren SES has NO influence on unloaded ride unless you drive like an eedjit and hit speed bumps too fast (which I purposefully did.) Once you eliminate the 3/4" clearance between the SES and the axle you'll feel the extra stiffness right away, but it was not a shocking hit. I'd describe it as "authoritative." I'm happy. 566992

After one year the Timbren Rear Suspension Enhancement System has performed as advertised. My 2016 F-250 does NOT squat with the fifth wheel trailer attached and the ride quality with trailer attached has also improved. Springs arrived quickly and took about 30-40 minutes to install. Excellent Product for towing!!! 449153

I own a 2006 GMC Yukon. We purchased a brand new 2017 32' Keystone Hideout Travel Trailer. The travel trailer remained well within our tow capacity when fully loaded. We also purchased and installed a weight distribution system. With all of these steps in place, the rear of our vehicle would sag. I purchased the Timbren SES Rear Suspension Enhancement System (Model TGMRG25C) from etrailer. The order arrived quickly within a few days. I was able to install myself in about 30 minutes. We just took the travel trailer out this past weekend. From the moment we hitched the trailer on, the difference was remarkable. No rear end sag at all. I would highly recommend this product. 433738

A year later and the suspension enhancement system is working flawlessly.

  • Timbren does offer a suspension kit for the rear of your 2001 Ford F-53 Class A Motor Home. It is the Timbren Rear Suspension Enhancement System, part # TFRF53A. It will install in place of the bump stops on the vehicle. They are designed to work with a suspension system that is in good working order. They are not designed to be used as the main suspension system on your vehicle. It works by being installed on the vehicles frame rail one inch above the rear axle. The one inch clearance...

  • Rear-End Sag in 2004 Silverado 2500 4X4 Crewcab With Weight Distribution System Installed
  • The best way to fix rear-end sag when towing your 7500-lb trailer with your truck is to use a weight distribution (WD) system. Rear axle suspension helper kits, such as Timbren jounce springs or air bag kits, are better for times when you are carrying a heavy cargo load in the truck bed. These will not give you the same benefits as a properly-tuned WD system when towing a trailer. In fact, if jounce springs or air bags are used along with WD, then they can sometimes interfere with each...

  • Timbren Front Axle Suspension Kit # TGMFK25S for 2006 GMC Sierra 1500 SLT
  • The Timbren front-axle jounce spring suspension kit you referenced, part # TGMFK25S, is a fit for both 2WD and 4WD versions of the 2004 Sierra 1500 SLT. These bolt-on without any drilling required (using included hardware) and replace the factory bump stops now on your truck. These and all other suspension enhancement products we offer are designed for use in vehicles whose suspension system is in good order. They are not intended to be an alternative to replacing a worn or damaged suspension....

  • Front Suspension Enhancement Recommendation for 2006 GMC Sierra 3500
  • The Timbren kit part # TGMFK25S that you referenced is a confirmed fit for your 2006 GMC Sierra 3500 but it's for severe duty applications so for you it would be very harsh. It would give you the support you want but at the cost of a very harsh ride quality. A better option would be the Air Lift AirCell part # AL52212 which gives you the support you would need but isn't as stiff so it wouldn't be nearly as harsh riding. This spring is 3.15 inches tall. There is also a small wedge as...

  • Will Timbren Suspension Enhancement System Allow 2006 Chevrolet Truck To Sit Higher w/ Plow
  • The Timbren Suspension Enhancement System, part # TGMFK25S, will prevent the front end of your 2006 Chevrolet Silverado truck from sagging so low when a plow is mounted to the front of the truck. This system is designed to work with suspensions that are in good working order. I have linked and FAQ and instructions for the Timbren Suspension Enhancement System, part # TGMFK25S. I have also linked a video installation of another model of the Timbren Suspension System, on a different vehicle...

  • Recommended Front Suspension Enhancement for 2007 Chevy 2500 with Snow Plow
  • For your heavy snowplow, I recommend the Timbren Front Suspension Enhancement System # TGMFK25S over the Air Lift AirCell Custom Helper Springs Kit - Front Axle # AL52212. The Timbren Aeon Rubber springs are simply stronger and they work in the same way as the helper springs, yet offer more support on the front end, so that first inch gets support.

  • Is there a 12-Volt Accessory Circuit on the 7-way of a 2011 Ford F53 RV
  • Yes, there is a 12 volt power source on the 7-way that is on your 2011 Ford F-53 RV. It will be on the 11:00 position of the connector as you look at the front of it. Check out the picture I attached that has a picture with all of the terminals of a 7-way labeled with their functions. You might want to test for voltage on this circuit with a Circuit Tester # 3808 as well just to be sure. I also attached an FAQ article on trailer wiring that you might find informative.

  • Recommended Front Suspension Enhancement for 2002 Chevy Suburban 2WD 1500
  • For the front suspension of your 2002 Suburban, I'd recommend the Timbren Aeon Springs, part # TGMFK25S. Installation is straightforward. You'd remove existing bump stops, and use the hardware and existing holes to instal the rubber Aeon spring. The springs get progressively stiffer as more weight is added to them, they typically come into play when a plow or some other very heavy piece of equipment is installed on the front of the vehicle. I'll link you to the installation instructions.

  • Timbren Suspension Kits for 2000 Chevy Silverado 1500
  • We have both front axle and rear axle Timbren rubber spring suspension enhancement kits for your 2000 Chevy Silverado 1500 that are displayed on the linked page. You can also see other kit options including air bags. For a rear axle Timbren kit you can use # TGMRCK15S which fits both 2WD and 4WD models. If you are interested in a front axle kit too, in case you use a snowplow for example, you can use Timbren kit # TGMFK25S for 2WD or kit # TGMFK15A for 4WD (if the truck is a 2-door model).

  • Timbren Recommendation for 2008 Chevy Silverado 3500HD Towing Heavy Fifth Wheel
  • The Timbren system I would recommend recommend would be the part # TGMRCK35S. It's the lighter duty of the two kits but the heavier duty part # TGMFK25S but it's going to provide a very stiff ride. The # TGMRTT35S still provides the 8,600 lbs of support which will work great. The HD is really needed only in very extreme situations like tow trucks.

  • Rear Suspension Enhancement Recommendation for 2003 GMC Sierra with Quadrasteer
  • I spoke with my contact at Firestone about whether or not the Ride-Rite Air Helper Springs, # F2190, will fit your 2003 GMC Sierra with Quadrasteer. He stated that none of the Ride-Rite kits would work on your specific vehicle. But not to worry, there is another option. I then spoke with my contact at Timbren, another maker of suspension kits. He stated that there was a kit available for your truck. Take a look at Timbren Rear Suspension Enhancement System, # TGMFK25S. These are an...

  • Suspension Enhancement System Recommendation for 2003 GMC Yukon 2 Wheel Drive
  • When it comes to a suspension enhancement system for your 2 wheel drive 2003 GMC Yukon, you will want to go with the Timbren # TGMFK25S. This system uses hollow rubber springs to absorb the brunt of the force on the front of your vehicle which helps to reduce sag and sway for better handling, traction, and a smoother ride. Part # TGMFK25S, for 2 wheel drive, and part # TGMFK15A, for 4 wheel drive, differ in design and installation. The 2 wheel drive version is a bolt-on kit where as...

  • Recommended Suspension Enhancement Kits for 2001 Suburban 2500 with AutoRide Leveling System
  • The AutoRide self-leveling and damping suspension system in your 2001 Suburban 2500 uses various sensors in the vehicle to control a compressor pump that continuously varies shock damping while driving. This system cannot be defeated and aftermarket air springs like the Firestone Ride-Rite cannot be installed on the vehicle according to my contact at Firestone. However, you can install a set of rubber jounce spring such as the Timbren front-axle kit # TGMFK25S and rear-axle kit # TGMRSB4S....

  • Rubber Jounce Spring Suspension Kit for 2006 Chevrolet 3500 2WD Flat Bed Work Truck
  • If you want a suspension helper spring kit that avoids the complication of air springs, then I suggest a rubber jounce spring kit from Timbren. We offer both front- and rear-axle kits for your 2006 Silverado 3500 2WD flat bed work truck. The rear axle kit I recommend is the Timbren # TGMRTT35C which is intended for heavy-duty vehicles. This is a bolt-on kit that requires no drilling. If you want a front-axle kit I suggest Timbren # TGMFK25S, also a no-drill install. The linked article...

  • Timbren Rear Suspension Enhancement For a 1999 Chevrolet 3500 2WD Dually
  • The Timbren Suspension Enhancement Springs, # TGMFK25S, that you referenced will fit your 1999 Chevrolet 3500 2WD dually, but these springs were designed for service vehicles such as tow trucks. Keep in mind, these springs are designed for the front axle, not the rear. It would be better to use Timbren springs on your rear axle when carrying your camper. For your truck, I recommend the Timbren Rear Suspension Enhancement Springs, # TGMRCK35. Adding a set of Timbren springs to your truck...

  • Spacer Recommendation for a 2006 Chevy 2500HD with a 2 in Lift Installing Timbrens
  • What you would want to use is a Timbren Spacer for Raised vehicles # A25723-90AH00. This spacer is 1 inch thick so you would want to use two of them since you have a 2 inch lift. For the rear you would want the Timbren Rear Suspension System # TGMRCK25S, for the front you would want the Timbren Front Suspension System # TGMFK25S. Since you will need 2 spacers per Timbren and you plan on putting them on the front and rear axles is looks like you would need a total of 8 spacers.

  • Recommended Suspension Enhancement for 2002 GMC Sierra 2500HD With Snow Plow
  • For your 2002 GMC Sierra 2500HD, I recommend the Timbren Front Suspension Enhancement System # TGMFK25S to help prevent the sag you are experiencing when the snow plow is attached. These springs have a 14,000 lb capacity and are going to do a great job of providing you with the support you need on the front of your Sierra. The Timbren system will help bear the brunt of the load when your plow is attached so you can stay level. They are also remarkably well-reviewed by our customers who...

  • Front Timbren Kit Availability for a 2001 Chevy Suburban 4x4
  • The part # TGMFK15A that you referenced will fit a 2001 Chevy Suburban 1500 4x4. If instead you have a 2500 model you would want the part # TGMFK25S. By nature these Timbren kits will not stiffen up the front suspension unless you have a decent load on the front of the truck. Unloaded you shouldn't notice them installed.

  • For your 2004 GMC Yukon XL we have the Timbren suspension kit part # TGMFK25S which fits the front suspension and then the part # TGMRSB4S which fits the rear. Both of these kits act like bump stops except are much larger to make contact sooner than the standard bump stop so that they can provide additional suspension support.

A coworker of mine installed these on his vehicle and said that along with the suspension support he was surprised by how well these worked as an anti-sway device.

  • Best Brake Controller, Suspension Enhancement, and WD System for a 2004 GMC Yukon Towing 7K Trailer
  • It looks like your 2004 GMC Yukon Denali has a towing weight capacity of 8,000 lbs. You will want to verify this in your owner's manual, but if this is the case and your loaded trailer weighs 7K then you should be good to go. If the 7K weight is without the trailer loaded then this could get a bit tricky and you will be pushing the weight limits of your vehicle. Adding a brake controller, weight distribution (WD), and some suspension enhancement will definitely help to make your towing...

If you'll be using the hitch to support a heavy load such as a snowplow or cargo carrier, you might want to consider some front-end suspension support.
