Features to know about

Stay Level Under Heavy Loads: 7,000-lb Rear Axle Support

When the bed or trailer weight starts to push the rear down, these hollow rubber springs step in with up to 7,000 lbs of load-leveling capacity. They sit above the rear axle and automatically add support when needed to reduce sag and squat. By keeping your ride height level, steering stays true, braking feels consistent, and the truck handles the way it should even with a full load.

Smooth Out Rough Roads: Rubber Springs That Absorb the Shock

Hauling heavy gear doesn’t have to mean getting beat up by every bump. The Aeon hollow rubber springs soak up road shock so you get a smoother ride under load. The progressive design cushions light loads but stiffens as weight increases, keeping the ride comfortable when empty and stable when loaded.

Tackle Uneven Loads With Confidence: Independent Spring Action

When cargo or trailers shift weight side to side, each spring works on its own to balance that load. This helps cut down on body roll when cornering or swerving, keeping your vehicle planted through turns and crosswinds. It’s also handy for off-center loads where one side needs more help than the other.

Simple Setup That Fits Right: Bolt-On Installation

No need for airlines or compressors—this system bolts straight onto the frame above the rear axle using custom-fit brackets and hardware. There’s no drilling required, and once mounted, it works automatically with your factory suspension. You get reliable support and stability without any manual adjustments or extra parts to maintain.

Built Tough for the Long Haul: Lifetime Warranty Confidence

Made for real work, these heavy-duty springs take on continuous towing and hauling without leaks or maintenance. They extend suspension life by reducing bottoming out and wear on factory components. With a lifetime warranty and satisfaction guarantee, they’re built to last as long as you need them.

Time will tell! Fast and easy install on my 2012 custom flatbed tundra. Hoping this will help when I overload my truck. I have about 900 lbs of extra weight on my truck at all times + Old man Emu heavy duty leaf springs.

I ordered the Timbren system for my Tundra and the slide in pop up camper that I will be getting soon, I'll know more when I get the camper on, but for now they are great.

2019 Toyota Tundra
Install was a breeze. Gonna be taking out 4klb travel trailer this Memorial Day weekend. Will update on how they ride. I'm sure I will be pleased.

Toyota Tundra
This thing is robust. Solid and looks indestructible. Replaced my OEM shocks to Bilstein and together they seem to work well. Installation was easy.
My Tundra does not squat now with heavy loads and the ride is firm not hard.
Thanks for selling a great product.

Still working as well as when I first installed it. Truck stays level when pulling our trailer. Really satisfied.

by:
Great product, be careful of installation , you should make sure that you have some free movement of suspension prior to engaugement / contact with the frame of vehicle ,ride will be much stiffer , worked well for my needs, heavy haul stablizer/ simple lift to rear axle

I put them on my tacoma for a year now, and can say it has worked out way better than airbags, very happy with the function and ride. I would buy them again.
by:
Timbren has always been the leading manufacturer of quality products. I deal with Etrailer because of their excellent friendly service.
by:
2007 Toyota Tundra
These items are built well but don’t mistake them for a cure to overloaded springs. I installed them prior to installing my camper and the truck was overloaded and riding with these against the frame. Rough ride for sure! So while they are built well, they really don’t help in my situation.
by:
Installed before going to trade my small travel trailer in on a bigger/ heavier one, didn’t do to well with the smaller/lighter camper, made the drive very bouncy!! But the ride home with the heavier camper was great, kept the truck level and helped it handle better on the road

2018 Toyota Tacoma
installation was extremely easy (after tangling with that one stubborn u-bolt nut found with any job). Instructions are straight forward and complete. Last time we loaded our ft. 18 camper on my Tacoma (tow capacity 7000 Lbs) I thought I was in the space shuttle at liftoff! Attached camper after installation and had rear end sag,even with bed filled with wood and coolers. Would love to post review after trip to Erie this weekend.
by:
Do exactly as advertised; have no idea why anyone would get air suspension when these do the trick with no hassle and automatically adjust themselves based on the load. Not to mention they are maintenance free.
by:
A friend recommended these, have always run air bags in the past. Price point was rite and install is a breeze, hopefully they work well.

As described

Have not got them installed yet, but the shipping was excellent & I expect this product to do what it is supposed to.

After a yr of towing with them they have softened a bit. They do cause a little more sway when towing. Normal ride height truck they sit on your bed frame so you will feel evry bump

  • Comparing Timbren and SumoSprings for The Rear Suspension of a 2021 Toyota Tundra
    The main difference when comparing Timbren and SumoSprings for suspension enhancement is going to be the weight capacities. Timbren uses hollow rubber springs that is able to support more weight but they can cause a firmer ride. The SumoSprings are made of a durable microcellular urethane that will progressively increase capacity as the spring is compressed. This will offer a smoother ride as the springs will better absorb the shock but they do not offer the capacity and stability of the...

  • Comparing Timbren and SumoSprings For a 2021 Toyota Tundra
    You are correct that the 7,000lb rating of the Timbren Helper Springs # T62FR and 2,800lb rating of the SumoSprings # SSR-610-54 is pretty different. For your 2021 Toyota Tundra I recommend going with the # SSR-610-54 as they are made out of a softer material so when you are driving the truck unloaded you will not have a stiff and bouncy ride like the Timbrens are notorious for. With that said the 2,800lb rating of the SumoSprings is actually higher than the payload rating of your truck...

  • Timbren Suspension Enhancement that Fits 2013 Toyota Tundra
    For your 2013 Toyota Tundra that is towing a 6,500 lb travel trailer I'd go with the Timbren kit part # TABSOSR to help support the rear of it and reduce sag as this will give you up to an additional 3,600 lbs of support if needed. Other kits provide even more support but they would provide a harsher ride quality. With that said, I think your best option would be the RoadActive Suspension kit part # RAS34FR which provides adjustable support, is easy to install, and also provides the best...

  • Jounce Bumper Helper Spring Options for 2021 Toyota Tacoma
    Some 2021 Tacoma were equipped with 3 leaves in the springs, some with 4, so you'd just need to take a quick peek at what you have to determine which Timbren kit you'll need, as I have no way to look up how your truck is equipped. For a 4WD with 4 leaves in the spring pack, use # TTORTUN4, for 3 leaves use # T72FR. For 2WD vehicles with 4 leaves, use # T62FR or # T72FR for 3 leaves. This being said, the Timbren systems offer much more support than what you'd actually need to counteract...

  • Suspension Enhancement to Help Sag of 2016 Toyota Tundra With Lift
    To help with the sag of your 2016 Toyota Tundra I recommend going with Timbrens, as they are designed to take the brunt of the added weight when you tow. They will engage when needed to counteract both sag and body roll to help level your truck, while also stabilizing it to help combat sway. You'll need spacers as well, but first, the correct fit for Timbrens on a 2016 Toyota Tundra are the following: - Timbren Suspension Enhancement System # T62FR The springs and bracket have a total...

  • Difference Between Timbren and SumoSpring Jounce Springs for a 2021 Toyota Tundra
    The biggest difference between the Timbren and SumoSpring jounce-style springs is that the Timbrens tend to be a bit more stiff which is great for heavier loads but can make the unloaded ride on your 2021 Toyota Tundra a bit more harsh. The SumoSprings tend to have a softer ride which makes them great for occasional cargo loads but they have less of a weight rating. Since suspension enhancement kits just offer support and don't actually increase your weight capacity it basically boils...

  • Best Suspension Enhancement For a 2018 Toyota Tundra When Towing a 2021 Lance Travel Trailer
    The best thing you can install for towing your 2021 Lance travel trailer is a Equal-i-zer Weight Distribution System # EQ37100ET. This will help you to level your 2018 Toyota Tundra and with the addition of sway control it will help keep your trailer tracking straight behind your Tundra. This particular hitch is rated for trailers up to 10,000lbs with a tongue weight of 600-1,000lbs. You will be able to use it with different trucks and trailers so you will not have to get a different suspension...

  • Comparing Timbren Kits for 2022 Toyota Tacoma
    There is an interesting amount of Timbren kits that fit your 2022 Toyota Tacoma long bed. The part # TABSTRFK is a standard duty kit that comes with a U-bolt flip kit helps with ground clearance. # T72FR is a severe service kit for 3 leaf springs which means it's going to be really harsh, # T62FR is same thing but for 4 leaf spring packs. # TABSOSR is a standard duty kit which means it'll give best blend of support and ride quality. This would be what I would recommend.
