Specs:
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'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.

Today on the 2001 Ford Ranger we are going to install part number TFRR0504A from Timbren. Before we started we actually did a few test runs. We did it fully loaded, halfway loaded, and empty. Now we will go ahead and install the Timbren kit and then we will go ahead and try it again.
The suspension enhancement actually replaces the factory bump stop right here. What is going to happen is we have got to take off this factory bump stop, it comes off there is usually a bolt on top, and there is a part that comes down here that gets clamped onto the axle and replaces the bump stop here on the bottom. Lets go ahead and take this off first.
We will go ahead and start the sub assembly. Whats going to happen is this screw will go on the inside. So just take it and put it into the end of the socket, and there is a little washer inside so you have to work it inside the washer. And it is going to bolt on to the top of this bracket here. And this bracket will actually get bolted onto the bottom of the truck. All right when you tighten these down you want to get these about hand tight. All right we will go ahead and install this part on the bottom of the frame now.
Go ahead and slide our lower bracket into place. Take care, stay away from any brake lines or any other components. Line it up straight. And then what happens is the clamp goes on the bottom and the two bolts will go through and hold it into place. When you tighten down the bolts you want to do them evenly on both sides. With one complete we will go ahead and move to the other side and start on that one.
On the one completed side you can see that we have about one inch of space between the rubber bushing and the bracket below it. When you get loaded up it is going to take up that space. The more load on it the harder it works. Here we go again, after the install we will show you how we can reduce the body roll in it with the heavy, light load, and no load. With a few simple steps and a couple simple hand tools we have our suspension enhancement installed. And there you have it for part number TFRR0504A from Timbren.

3,000-lb Capacity. These hollow rubber springs sit above the rear axle to help stabilize and level your vehicle. They also provide a more comfortable ride by absorbing road shock and improving roll stability. Easy to install and use.I have an 18 year old Ranger that I put a snow plow on a couple of years ago. To avoid the extra strain on the suspension I put Timbrens on the front. Last year I started pulling a trailer so decided to put Timbrens on the rear as well. My truck is more stable and handles the extra weight on both ends much better. They are a great investment in an old truck that I really like.
Excellent add on my Mazda B4000, 2002. After 9 years, my rear supension needed a lift-up and that was the perfect solution. Easy to install and cheap with significant improvement when taking corner, stop and acceleration. Everything hold on tight. At the beginning the Timbren was very stiff and hard, even too much when driving empty but now it did soft-up and I got use to it. The big difference is when the trunck is loaded... WOW. Very good purchase.
Works great on my ranger pickup.
Easy install took about 20 minutes on my 2017 Ram 3500 SRW. Had about 1/2 inch clearance as recommended. Loaded up my 5th wheel (2350 hitch weight) and about 200 lbs of gear in the bed. Just got back from a 800 mile camping trip through mountains of TN. You can really feel the difference around those sharp corners and uneven surfaces. The truck felt firm and controlled not hard and jarring as some have mentioned. Going over those overpasses with the wonderfully smooth (Not) joists was greatly improved. The truck would squat and rebound again, with a firm controlled response. Driving without a load felt the same as before without them. I would highly recommend these! Ordering from etrailer continues to be my go to option!
The product came very fast. I already installed it the same day on my 2009 Dodge Ram pickup. It looks like it should do a fantastic job. I'll know better when I hitch up my travel trailer.
Took about 45 minutes to install. But that was 2 trips into the house cause my deep drive sockets were buried. F-350 gasser with 8’ box, Fiberglas cap, 200lb wooden storage drawers and estimated 400lbs in tools. I tow a 14k bumper pull dump that squats the truck. I installed the spacer with the timbrens and it sits on the original axle stop. Ride quality is unknown as I haven’t driven it yet.
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.
Installation was a breeze, removed old bump stops installed Timbrens in about 30 minutes. Haven’t put a load on them yet so I’ll update later. Installed on a 2008 Silverado 2500HD..
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.
Out of the box fit !!
Only issue I had was keeping the wedge from moving during installation
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.
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.
After successfully using air shocks with on board compressor on our 2001 F250 for years, I almost automatically put the same setup on our new 2022 F250. We tow an 11k lbs travel trailer. Then I read reviews on Timbren Suspension Solution & thought, worse case I’ll end up with both solutions. After spending 20 minutes installing Timbren and towing the trailer a few miles, it became obvious I didn’t need air shocks, or anything else. The truck & trailer drive as one. Our rig is level and rides great. When the trailer is unhitched, the Timbren’s aren’t engaged - just a normal F250 ride.
The Timbren rear suspension bump stops are the best by far. I installed this unit on a 3rd gen Toyota Tacoma which became an essential item for safety towing purposes.
The main reason for purchasing this product was for aided support for towing. This is essential for those who tow boats, tear drop trailers or medium sized campers.
The stock bump stops are relatively small in size which is standard for other vehicle manufacturers however Timbren's bump stop are made with such high quality material and craftsmanship.
This also helps in preventing in stressing the front suspension from becoming raised which can affect your steering when your towing. The Timbren bump stops also helps in preventing your rear suspension from the "sagging effect" which can cause stress to your tires.
I recommend that when you install the bumps stops, check the lugs every quarter or depending on frequent you tow, to include tightening the lugs with a torque wrench to ensure it's torue specification(s).
This product has given me peace of mind when traveling long distances and when camping off the grid. Timbren also has good customer support service however etrailer has paramount customer service as well.
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.
Caution,these parts did not fit my 2008 Suburban 1500 as advertised. Also FYI, Amazon also says they will fit. After some alterations I got them to finally seat. Tha original bump stops have a groove cut into them about a 1/2" from the top to accept 6 pertrusions that are stamped in the bump stop cup. After several attempts to press the Timbrens into place they wanted to pop out or were very easily removed with little pressure.I ended up cutting in 6 notches with a utility knife. Photos attached. I used markings on the old bump stops to determine spacing. I marked the Timbren with chalk to illustrate approximately where I notched them.Caution, cutting hard rubber with a utility knife is dangerous if you are not used to using a utility knife. I believe Timbren makes a spacer with a groove cut in them. That would make installation a lot easier. I cannot fault etrailer because they probably are following Timbren specks. Also I am not sure all Suburbans of this era have the same bump stop cup. I would recommend checking your old bump stops before ordering. Hope this helps.
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.
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.
I just installed Timbrens in our 2024 Sequoia Capstone. It has 22" wheels so I was able to slide under the rear axel and swap out the factory parts without jacking or removing the the wheels. It took me about 20 minutes to do both sides. With no load I can fit almost two fingers between the axel and the bottom of the Timbren. I tow a 29' boat that has about 600-700 lbs of tounge weight. The Sequoia sits pretty level and rides great. I had a 2010 Sequoia before this one that I installed manual rear coil airbags that worked well. I like the Timbrens as there is no pumping every time I tow.
I was able to pull my RV with 550lbs tongue weight without the excessive rear end squat. I did notice however that I can feel them engage during normal unloaded driving when I drive over dumpy parts of a road where before there was more spring travel. It’s not bad but a stock 97 f150 does have a smooth ride. These will take some not, all of that away. But the up side is well worth limited ride change.
The last two things I bought from E-trailer looked like they were used. This one at least had all of the fasteners, although they didn’t seem to be the ones in the directions. These had Allen heads and I had to buy a socket that had an Allen key. The directions included aren’t very clear. I had to find some YouTube videos to make sense of the install unloaded I can’t tell any difference, which is great. Hoping this fixes my backend squat with the boat trailer attached which is so severe I can’t flip down the trailer jack. Fingers crossed. Get a jack under the hitch and really unload the axle from the frame. Once I got enough clearance it was truly a 30 minute job.
A year after installing these and many miles old towing I heartily recommend them. F150 is totally level while towing a 7000 lb fifth wheel. Great economical solution to sag!
Super simple to install. My 2018 f150xl would almost hit the bump stops when I hooked up my 7x16 enclosed trailer. Now, it almost rides level. Much safer feeling ride also. Without the trailer, it rides like an unloaded dump truck. It is what it is. I'm happy with them.
Absolutely fantastic! So easy to install. These have completely change the ride quality while hauling our truck camper. The truck now rides better loaded than unloaded. The gap under the SES is small, less than an inch. So unloaded ride is a bit ruff since it bottoms out super easy on the smallest bump.
But if I wanted to I could take them off since they go on so easy.
I still wouldn’t pass up having these. I can’t say enough how great they are. And I ordered a used set which were in new condition. Less money, same awesome outcome. Can’t go wrong!
