An example of sag on a truck's rear axle under a heavy load. The Timbren Suspension Enhancement System levels the vehicle.

When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the vehicle sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but more of the vehicle's weight as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall vehicle handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the vehicle's factory suspension to keep the vehicle level and improve your driving performance.

Diagram of the Timbren spring installed

The Timbren system has a vehicle-specific bracket that will be 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 one inch 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 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 provides increased resistance, stiffening the suspension and keeping the vehicle level.

Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's or passenger's side of the 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 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 helping 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 passing of a semi) because the movement from the trailer is not transferred to the vehicle. This also works to make the sway subside quicker.

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 as the rubber springs work to prevent bottoming out on rough roads.

Compared to the competition:

Timbren's suspension enhancement systems are much easier to maintain than air springs - no air hoses are needed to be run, no compressors or gauges to hook up, and no manual adjustments necessary. The rubber construction causes Timbren's springs to be more elastic than similar products constructed of micro-cellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

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.


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!!

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!

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.


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.


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.

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.

2020 Honda Odyssey

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

Product still works great? No Squat.. No .. No Bouncy.. Better stability when cornering.
Clark G - 07/19/2021


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. 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.

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!!!

2020 Honda Odyssey

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


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


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

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.


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.

2019 Honda Odyssey

These worked great for my family and I in our 2019 Honda Odyssey. Our last trip was to Myrtle beach and we were loaded to capacity, our van handled the extra weight just great! I also towed a small car on a dolly to my home, about 15 miles and our van composed greatly. Sadly our van is gone but the experience of Timbren will always be with me!


Installation is OK. But the ride is very tough for a minivan. This product is more for the truck I think.


Love these Timbrens on my minivan. Had these in a previous van and now our 2020 Honda Odyssey. It helps with stiffening the rear up in what is otherwise a very squishy rear suspension. Installation is very easy. It was harder to pry off and out the old ones than to install these. Just a little petroleum jelly, work one end in and apply some leverage on the top to have the otherside pop right in.


Good product. It was not too hard to install. It reduced the amount of sag or squat when the van is loaded full. It didn't affect the ride quality.


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.

Honda Odyssey

I have not fully loaded my Odyssey yet BUT compare to original “pacifiers” which are made from kinda tough popcorn, those timbers are looking reliable.

2022 Honda Odyssey

Thanks you, really good service….


Fast shipping, easy install! Will be ordering more soon!

  • 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.

  • Does Draw Tite Hitch for 2019 Honda Odyssey Have Capacity for Motorcycle Carrier
    When the tongue weight capacity of a hitch is determined the manufacturer factors in the typical ride quality issues like you mentioned.
