Whether you're hauling heavy loads in your bed or cargo area or you're 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.
The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above the rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the 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.
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.
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.
Because the 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.
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.

2019 Ford F-450 Super Duty
For me this last transaction was not very etrailer like. The Timbrens are good.
Before I ordered the Timbren SES on the eTrailer web site I had a few questions so I called eTrailer. A woman answered and really wasn't very knowledgeable about the product but didn't offer to pass me along to someone who was. She instead referred me to Timbren. I was a bit put off and thought why should I buy from etrailer then. I told her "well I'll just buy straight from Timbren then". She was a bit snarky and said they may not sell to the public (which they do, something else she wasn't aware of). I checked the Timbren site. Their price was a tad higher and the delivery would be later so I went back to the eTrailer site and just purchased the Timbrens.
At the time of ordering, the delivery was estimated to be Nov 8. Since I was leaving on a trip on the 11th, this would give me time to get them, install them and test them.
The package didn't arrive until late on the 10th - two days late. The Timbren box was in rough shape. It looked like it had been previously opened and then overly taped back up.
I opened the box and did a quick inventory. Just my luck, it was missing the bolts and shims. I called etrailer to inform them but they couldn't do anything for me quickly. As I was up against a timeline, I went to a local hardware store and bought the needed hardware for just under $5 but what an inconvenience. It should be noted the other components in the box were in good shape. The installation thereafter was a breeze even in the dark.
Since I was leaving on my trip in a few hours I could only hope the Timbrens would work as well on this truck as they did on my 2015 since I didn't get a chance to test them.
While they did credit my card for $5, I received absolutely nothing from Timbren after emailing them with the above information.
The Timbrens are a good product but etrailer fell flat this time.

Great product, it works perfect on my truck. Sometimes I tow up to 30k lbs including my trailer and my truck stays level. No more high beam flashing in my eyes from drivers going in the opposite direction on the road.
by: Kyle09/07/2023
After attempting to install airbags that ultimately had to be returned bc of a Fitment issue, I switched to the Timbrens. Although they make no difference unloaded, they helped settle the rear axle down when towing our 5th wheel. Satisfied with the product, easy to install. The folks at etrailer were helpful with the exchange.
by: Evelio06/15/2021
They are excellent. However, the real excellent part is that the original pair ordered was stolen. Yes, you heard correct and I’ll say it loudly, they were stolen in transit and ups literally delivered an empty box. A box that clearly states 10lbs they actually had the gall to place at my door completely empty. But etrailer stepped up and made it right. That’s the true excellent part etrailer’s service. They are fantastic.

Timbren bushings are great because they are simple to install, have no ancillary systems to rely on like compressors, and self adjust with changing loads. I have used them for years on multiple trucks and only had one bushing break. Timbren replaced it for free under their lifetime warranty! This is a great product.

by: John Z04/19/2023
I know it will be lovely when loaded or the trailer on. However,it rides like a wagon empty with brand new premium shocks and struts empty. Thud thud thud. You really cannot feel the shocks or suspension. Found exact same item plentiful for 60 bucks on eBay after I bought these for 250. I may cut these in half or put air bag on. I do not like the ride empty. No hard feelings. It is a good product maybe just not for me.
by: Shaughn10/21/2022
About a 1/2 inch difference in gap at the bump stop perch but still within parameters. Truck sits perfect with trailer attached. Haven’t towed yet. After towing if they perform like they should will upgrade to a 5 star. Easy to install, definitely needed 2x4 and jack. 2011 Silverado ext cab with 30 ft Genisis 5th wheel.
by: Michael03/12/2023
Was able to install these with a 15mm flex head ratchet wrench and lifted the rear of the truck to make it easier. 30 minutes to take off 4 nuts and put em back on. 2 minutes assembling the timbrens with the added spacer. I have a f350 with a salter and plow. Loaded with salt the lights shoot up and in the snow ?? it’s like hitting hyper drive and you’re blinded. These helped big time. Very happy so far.
by: Paul10/20/2022
Haven’t had it on long, but so far so good. 1999 F350 dually. Bolted up nicely. Total job took 10 minutes. Have hauled two gooseneck loads of hay and truck drives SO much better. Nice and level. Money well spent so far.
by: Tim03/17/2023
The pro: The longer, heavier bump stops worked great when hauling my mustang home from Chicago. The truck stayed level and handled great.
The con: I had to remove the bump stops for everyday use. They limited my suspension travel causing a stiffer ride.
by: OmarG03/08/2023
I am so glad I bought these for my truck. I was able to install them myself using a jack and jackstands. The ride is bit rougher now; but the suspension is totally awesome compared to before. I am able to haul a bit more weight when needed.
by: Francis02/20/2023
very good product ,received just in time and fit perfectly on my GMC savana 2000 .Be sure to clean the two receptacle thats help.
très bon produit , reçu dans les délais et s'ajuste parfaitement . Assurez-vous de nettoyer le receptacle cela facilite l'installation.
by: Jeffery08/03/2022
The timbrens actually did what they were suppose to do. However, once I starter driving out west I notice the timbrens were riding on the axle which cause the speedometer to jump around depending on the road. I would recommend them if you are hauling or towing a camper or RV. I was going to contact etrailer about maybe removing a spacer for one set however the other set came as one unit. The bottom line is the Timbrens does stabilize your load for safe travels. I will be contacting etrailer soon to assist in correcting the problem...Road trip from Idaho,Colorado,Wyoming,and Utah were beautiful... Thank you etrailer
by: Raymond04/04/2024
Definitely a must have when towing..stiff without a load but night and day difference while towing my travel trailer, better traction, steering and braking. Easy quick install..only issue I had was with the long bolts they sent with the spacer kit (optional for lift) the bolt diameter was too wide to fit through the holes on the bracket..but a trip to the local hardware store took care of that.
by: Jesse03/20/2024
Pros: Cheaper and easier to install than airbags, do the job when load is enough to compress the shock, with added weight or towing, then it stiffens the rear very nicely.
Cons: Doesn't do anything until there is 2-3cm of compressed shock. It sits above the contact point, doesn't touch. Under normal driving, there is no benefit/improved stiffness/anti sway in rear or a leveling of the factory rear sag in a 2022 or newer Toyota Tundra.
If had it to do over, would have put some kind of spacer in between product and upper included bracket, the supplied bolt is long enough to accommodate, to eliminate the gap, and lift the rear 1-2 cm. Should do it anyway, maybe when swapping to summer wheels next month.
by: Little Doc11/29/2022
I’d seen similar products rated in the 4,000 lb ratings but I went with these. I’m not a mechanic but I removed the factory bump stops and installed both these in 30 minutes or less. I used my rolling jack and lifted from the drop hitch and easily removed the old ones and soapy water and 1/4 twist and these were on. Placed a block of wood in the space between these coils and lowered the jacks then pressed it with my tractor to confirm full engagement. I carry a lot of tools on a 2020 Chevy 2500 I do feel a bit of butt bounce on large bumps but other than that I’m very pleased.
by: Phil 04/18/2023
The order with Will at etrailer was great. He was very helpful and knowledgeable, Installation was not easy but not too bad, The hardest part was removing the factory pieces I removed them from below which was a blind nut removal operation. This is on a 2017 Mercedes Sprinter motorhome. After removal of the factory pieces I discovered that access is much easier on top between the tire and the mud flap, I turned the front wheels inward and they didn't have to be removed. The front of the motorhome had to be raised quite a bit to get the Timbren piece jnserted. Also I learned to tighten the bolt and nut in the Timbren bumper as much as possible before installation because there is no access to the bolt head when tightening the top nut to keep the bolt from turning, preventing tightening the nut.
by: Mark05/09/2024
First off the product was beat up with paint/power coating missing in several places on both. I was putting on a brand new truck with less than 800 miles on it so I elected to touch up before install. I’ve hear a lot about Timbren but never had them. I had airbags on my F350 but when I switched to a new Tundra I went with Timbrens. I’m a bit disappointed in the ride. Feels like I can feel a “bump” in the truck from the rubber pick hitting the axle when I go on a bumpy road. Thinking I should have went with airbags. As far as having a load on the truck and helping with the squat, they do as they are advertised.
by: Henry 05/12/2023
They do exactly what I wanted them to do. They support my boat trailer and when not towing, they don’t touch the bumpers everything’s great.

- 2024 Ford F-450 Super Duty Timbren Suspension Enhancement Kit RecommendationI recommend going with the Timbren Suspension Enhancement System # TFRSDJ for your 2024 Ford F-450 Super Duty because it's designed better for pickup truck-type applications. The other Timbren kit # TFRTT350J is designed more for Severe Service vehicles like that will have more constant heavy loads in them (like a slide-in camper, salt spreader, or crane) so if your F-450 is only going to be used like a pickup then the first kit is what you want to use. We've actually had the opportunity...
view full answer... - Non-Airbag Suspension Upgrade Option for a 2019 Ford F-450If you are asking for a suspension upgrade kit that has adjustable bags that do not use air, I am not aware of any that exist. If you are just asking for a suspension upgrade kit that does not use air, then we have the Timbren Suspension Enhancement System # TFRSDJ. This system installs directly onto the frame of your F-450 and works independently for side-to-side load leveling. It becomes more rigid as more weight is added and acts as a shock absorber.

If you are looking for a Air Lift brand kit, you can use the Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88349, but these have a weight capacity of only 5,000 lbs.

view full answer... - Is Timbren Suspension Enhancement for 2021 Ford F-450 Super Duty 4WD Compatible With 5th Wheel HitchThat's a good question, and I can confirm for you that the Timbrens which fit your 2021 Ford F-450 Super Duty 4WD, the Timbren Suspension Enhancement System # TFRSDJ are 100 percent compatible with a 5th wheel hitch. They install between the frame and your axle, so they will not interfere with 5th wheel (or gooseneck) brackets. The Timbrens are a really good choice for your F-450 because when you have additional weight at the rear of your truck - like when you are towing - the added weight...
