An example of sag on a vehicle's rear axle under a heavy load

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.

Diagram of the Timbren spring installed

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.

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 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.

An example of a trailers swaying

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.

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. And more elasticity allows for a more comfortable ride because the rubber has more travel.

Honda Odyssey

Easy upgrade!
Most helpful tips - put
the Timbrens in the freezer overnight to shrink them for easier install; use a ratchet strap to remove old bumpers; and I was able to use a big C-clamp and lube the Timbrens with simple green to press them in.

I installed these on a 2020 Honda Odyssey. Unloaded the ride was still smooth as factory for small bumps but stiffer for large bumps. Of course minivans always have a varying amount of weight in them.

Then pulling a ~2500 lbs Aliner Expedition with a 220lbs+ tongue weight, the van has plenty of power to pull the camper but there was definitely a lot of sag before installing. Then Timbrens made a big improvement in loaded ride height and quality. Only downside is there is a frequent squeaking noise over bumps but worth it for all the upsides. I do not hear any noises unloaded.

Jonny Z.


All the noise and squeaking has gone away. Still pulling the camper with the van with no issues. I get asked all the time about my camper and towing it with the van and the Timbrens are a must!


Just now installed, and OK overall. Slight increase in bump response unloaded, but valuable rear suspension support when loaded. Jury is out for effect when towing, as I have not yet done that with the Timbrens installed. Useful if you intend to load up your 2018+ Odyssey.

2018 Honda Odyssey

There is not much to it, it’s just a rubber bump stops. They do keep my 2018 Odyssey more leveled under load and make ride stiffer a little and a bit wobbly when under load.
They are very overpriced! The fair price range for the its purpose and performance should be $90-100


Worked great on our 2019 Honda Odyssey Elite to the East coast.Fully loaded with 4 people and a car top carrier,the Timbrens kept the van stable and level.
Sold the 2019 but took the Timbren system out and put them in our new 2022 Elite. Very easy to install, highly recommend.

2023 Honda Odyssey

Installed there is 1" of space between the top of the Timbren and the van frame when empty. It takes just one person in back to lower the frame onto the Timbren. The van rides fine when bottomed out on the stop.

The product installed in about 10 minutes a side. Removing the OEM was simple. Just use one of those cheap Harbor Freight pry bars and twist with it. Spray Armor All as you do it and it'll pop out with a little work. Install was even more simpler. Spray Armor All again on the Timbren and place a 8"+/- long 2x4 above it and lower the jack. I did each side twice even though one side completely seated itself on the first try. I would have preferred air bags as that's what I had on my other minivan but none are designed for a '23 Odyssey.

FYI, etrailer does not ship fast. Not a big deal if you have time but I ordered from our vacation location b/c my headlights were shining to the overpasses on our way there. UPS cheats on the business days shipping count. End result, these Timbrens arrived in FL 3 hrs after we left on our way back home. I had to pay postage to get it back to my house. Nobody would stand behind any of their shipping quote dates because of ridiculas technicalities. Very frustrating.

2018 Honda Odyssey

Installation was a little tricky, I used a ratchet strap, and carefully wrapped it around the tire, and around the stock jounce stop, tightened it up and they easily popped out. The Timbren's however were a little more stubborn, I lubed them up with soap and water, and as I didn't have a short piece of 2x4 or anything of appropriate strength or size, I simply cut the top off of one of the old jounce stops, and used that as a spacer to stack on top of the Timbren's, it took a few tries to get the angles right, but once lined up (keep in mind that the arm moves up at an angle, not straight up and down) and I dropped the jack, they popped right in! Driving has become greatly improved, the handling feels much sportier, the lack of dragging my receiver or drawbar is an absolute plus as well. The pictures don't do it justice, however the before and after pictures were taken from the same exact height from the ground, so you can compare, it is now nearly stock height with a very heavy load in the rear, at least 1.5" higher than before. Also of note, the stock jounce stops were completely smashed into the frame from the weight, whereas these still have a long distance to compress. I haven't driven the van unloaded, but loaded as it is/was, the rear can be slightly bouncier, but you no longer feel that hard bottoming out. I know they can seem pricey, but they are worth every penny and I am going to yell out to the mountaintops for everyone I know to buy these things, highly recommended!!!


Works well for what I intended. Which I carry about an exstra 300-400lbs in my van . With this kit it keeps my van from sagging in the rear. It is a little bit more bouncy when empty, but I have weigh in the van most of the time. So it does what I needed.

2020 Honda Odyssey

Mounted these on Honda Odyssey 2020 to firm up ride when loaded and pulling small cargo trailer. No more bouncy bouncy.

Clark G.


Product still works great? No Squat.. No .. No Bouncy.. Better stability when cornering.

2018 Honda Odyssey

Way to expensive for what you get from it. Very hard to install as it is not as rigid as it looks, replaced brakes and shocks and installing this was the hardest part of it all. There is literally nothing else in the market that would replace worn stoppers other than replace the whole control arm which is discontinued, so $XXX for a $XX bushing it is...

Honda Odyssey

I installed these in our 2022 Honda Odyssey prior to a 2 week camping trip. With a medium load the ride in the back was a little rough but when we really loaded the van down the ride was much better. Glad I installed these.

Removing the old bump stops was easy using small ratchet straps around the tire. Installing the timbrens was even easier using a little piece of 2x4 and lowering the jack to seat them.



A year and 2 heavily loaded road trips later these bump stops are doing great!


Installed them on a 2018 Honda Odyssey, was very simple to install, removed the rear tire and old bump stop, used a bottle jack to put the new ones in place, installed 22” rims on the van and no rubbing at all so far


They are great. They keep the van level and it does not bottom out. Great Product!!!

2023 Honda Odyssey

Very easy to install on a 2023 Honda Odyssey after watching videos online. I used a very large flathead screwdriver to pop the old ones out which required a lot of force. I soaked the new ones in ice water and sprayed with soapy water when installing using a couple pieces of scrap wood and a jack. The whole process took about 20 minutes with most of the effort getting the oem ones out. So far the ride unloaded is unaffected and the extra support is nice when the back is weighted down.


I'm grateful for these Suspension Enhancements, it really helps because I have a electric chair lift on the back of my mini van. Thank you so much!!

2019 Honda Odyssey

Shipping was fast and packaged well. This Timbren is a hard rubber that feels very durable that can withstand heavy loads, not unlike the stock. It took me 4 tries with the use of some 2x4s and a spray of WD-40 before the Timbren snugged in place. I haven't tested this yet loading my van at full capacity but it looks like it can handle the task!

Honda Odyssey

Definitely helps with the squat factor in our Honda Odyssey. Honda advertised 7-8 passenger seating but, once loaded, the van squats badly and is bottomed out. The Timbren spring bump-stops help tremendously.


We notice a significant difference in the minivan's handling when changing lanes and when hitting large bumps. Without these, the van's weight was too light on the front wheels. This product replaced the factory installed axle bump stops. Glad etrailer made these available.


I have not had time to install these but they look good and delivery was on time. I have installed the wiring harness and it is god and as advertised. it worked with no problem.


Made a huge difference from the factory bumpers! This keeps the wheel below the top of the wheel well when full loaded or pulling a trailer.

2020 Honda Odyssey

I love it, while replacing it in the driveway is little bit of a challenge, it’s definitely worth it.


2020 Honda odyssey. Install was a breeze shipping was fast. Day and night difference once the timbren were installed. Handles so more better and no more worries on the rear sagging under load.


Excellent suspension enhancement, greatly reduces excessive sag with a heavy 4 bike rack attached or loaded van. Highly recommended!


It really helps! I loaded a trailer with pebble stones to fill my garden, over 1,500 lbs of stones and could tell the difference before the Timbren, it held the weight and the car was not sagging. Before, a 350 lbs wheelchair mounted in the back made the wheelchair carrier scrape the pavement.

2018 Honda Odyssey

Along with my tow bar, I received a used suspension piece, that was strangely more expensive than the entire tow bar. Looked like it had been rode hard and put away harder. Would love it if I received new, unreturned parts when I’m paying full price. If you want to resell returned parts, they should be so advertised and cheaper than new.


These work great but TOO stiff for my application (2019 Honda Odyssey hauling about 600 lbs more than normal). Write up says 2000 lbs but when you look them up on Timbren web site, it says 3500 lbs. I contacted Timbren and they replaced them with a "softer" spring that works just fine.

  • Will the Timbrens for a 2019 Honda Odyssey Raise Ground Clearance
    The Timbren Rear Suspension Enhancement System part # T26FR which is a fit for a 2018 Honda Odyssey is not designed to lift the vehicle, rather reduce sag which in a way can be viewed as lifting. In other words, if you are loaded with cargo and the vehicle sags or squats then installing the Timbrens can raise the ride height. It however would not raise the ride height unloaded.

    When the tongue weight capacity of a hitch is determined the manufacturer factors in the typical ride quality issues like you mentioned.
