Upgrade your vehicle's rear suspension with these maintenance-free helper springs. They smooth out bumps, reduce sway, and help keep your vehicle level when towing or hauling. Durable urethane design installs easily with no drilling required.
Whether you're hauling weekend gear or towing a small trailer, these springs adapt to the load. Light cargo compresses them slightly for a soft ride, while heavier loads activate more resistance - keeping your truck level and your drive predictable.
Designed to handle harsh environments, the closed-cell urethane resists road salt, oil, and UV damage. With no air lines or fittings to worry about, its a "set it and forget it" solution built for year-round reliability.
Hit a pothole or a rough stretch of road? These springs act like a cushion between your frame and axle, soaking up impact to reduce jarring and minimize bounce. It's a small upgrade that makes a big difference in comfort.
Carrying a tool chest or cargo that sits off to one side? Each spring works on its own to manage side-to-side movement and reduce body roll during turns, giving you more control on the road.
These springs are manufactured in the United States with high-grade materials and strict quality standards. They're backed by a limited lifetime warranty for confidence that goes the distance.

Hi everybody, Andy here with etrailer.com. Let's take a real quick look at the Sumo Springs Rear Axle Custom Helper Springs. Now this kit has been designed to fit your 2024 and newer Toyota Land Cruiser and Tacomas, and your 2022 and newer Lexus LX600, and your 2023 and newer Toyota Sequoia. On custom fit parts such as this kit, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Simply input the year, make, and model of your vehicle and our fit guide will confirm if these will work for you or if we have something comparable that will work for you. So whether you're hauling weekend gear or towing a small trailer, these springs adapt to that load.
Light cargo is going to compress them slightly for a soft ride, while heavier loads are gonna activate more resistance, keeping your vehicle level and your drive predictable. Now these have a weight capacity of 50% compression of 1400 pounds. But do be aware of the fact that Sumo Springs do not actually increase your vehicle's weight carrying capacity. But these are designed to handle harsh environments. The closed cell urethane is going to do a great job of resisting salt, oil, and UV damage.
And what's nice about this kit is you don't have to worry about any air lines or fittings. This is basically going to be a set it and forget it solution built for year round reliability. If you hit a pothole or a rough stretch of road, these springs are gonna act like a cushion between your frame and axle, soaking up the impact to reduce jarring and minimizing bounce. So it's gonna be a relatively small upgrade that's gonna make a big difference in comfort. So if you're carrying like a tool chest or cargo that sits off to one side, each spring's gonna work on its own to manage side-to-side movement.
That's gonna help reduce body roll during turns, giving you more control on the road. So this includes everything that you see here. You're gonna get the springs, custom fit brackets, hardware, some lock tie here, and then instructions to guide you through the pretty simple, in my opinion, installation process. If you do pick these up, we would love to hear back from you regarding your experience with getting these installed and using them, so you can share your experience with us by dropping a comment or leaving a review on this product page. And if you happen to have any other additional questions, don't hesitate to reach back out to us.
We wanna make sure that you're getting exactly what you want and need. Well, that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
Instruction could be a little more deta iled.
Always great customer service and speedy delivery.
SumoSprings easy to install, no issues.
Always the fastest shipping, outstanding customer service and high quality products.
Very easy to install. Will keep my Tundra from squatting too much when I tow.
Added 2” spacers on each side so the Sumosprings touch my frame. Relatively easy to install, but centering on the frame was a challenge as the directions tell you to touch the wire harness bracket. I elected to be slightly off center so the bracket did touch to prevent movement and wire damage. Also, once initial installation is performed, you must remove to tighten, which is not in the directions. Overall, the ride has not changed at all and it helps eliminate the drop from my trailer. Highly recommend!
Very fast delivery. So far so good.
Very easy to install and worked well.
Easy install. Rides awesome!
Easy to install, so far truck pulls the trailer much better.
Good product unfortunately it did not solve my ride issue but not at fault of the helper springs. Just bad engineering by GM. The helper springs were very easy to put on, less than an hour to put both front and rears on.
Package arrived intact only 5 days after ordering. Contents undamaged and well packed. On my new 2024 Toyota Tundra the installation was very simple, straight-forward and easy. In my garage I raised the rear of the truck with a floor jack, gathered my tools and started about 45 minutes after the package arrived. Took me about 20 minutes on the drivers side because I lacked any previous experience with this product. Only took about 10 minutes for the passenger side because I was more comfortable after doing the drivers side. I didn't even have to remove the rear tires. Keep in mind that I am a very mechanically inclined yet 68 year old guy laying on a creeper underneath a wet truck. The mounting brackets are very heavy-duty and thickly painted. Actually heavier duty than the originals. Bolt holes in the brackets were exact matches for my Tundra. After lowering the rear of the truck back down there is still approx. 3/4" clearance ( previous 6" clearance measured at the original factory bump-stops prior to removal) between the bottom of the Sumo helper and the axle rest. This is about the amount of clearance I was hoping for---make contact at about 5-1/2". Leaves me about 3/4" free travel during everyday, unloaded driving. Without the Sumo's my truck sagged 3" with 575 lbs camper tongue weight. Raining outside so I'm not going to hook up my camper just to measure the difference today. However, if it now sags even 1 to 1-1/2" less than before, I'll be a happy camper (pun intended).
I gave this a 5-star rating because I received everything exactly as advertised. Also because I can see how this product will absolutely make my camper-towing experiences much more pleasant and safe. And the Limited Lifetime Warranty certainly was a factor. I usually don't take time to write reviews but I was so impressed with the overall quality of this particular product and the ordering process that I felt I owe them that much as a tip.
