1,000-lb Capacity. Upgrade your Chevrolet Tahoe's rear suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.
Features:
Specs:
A heavy rear load can cause sag as your factory suspension compresses under the weight of the load. This means that the rear axle is trying to support not only the extra load but also the weight of your vehicle. And because there is less weight on your front axle, your front tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.
SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The closed-cell urethane material allows for smooth contact between the springs and your vehicle. And the springs act like a shock absorber to dampen road vibration.
The springs can also compress by as much as 80 percent to support a heavy rear load and to help your factory suspension bear up under the load. This evens out the weight, which levels your vehicle and ensures that your front tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.
The springs work independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.
These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).
SumoSprings compress vertically with minimum expansion to the sides, so they won't be damaged by nearby mechanical parts and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.
The helper springs are custom designed to fit your vehicle, and they install easily - no drilling required.

1,000-lb Capacity. Upgrade your vehicle's rear suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.Seems very robust. Looking forward to towing the trailer in the spring! Relatively easy to install, but thanks to a little [online] search, I was able to install them more easily. The steps for installation did not call for any lubrication of the top of the spring in order to get it into place, but it definitely needed it. I took multiple attempts to try and install them without and they simply wouldn't slip into place. I used a little bit of Simple Green in order to provide the lubrication that they needed to slip into place. It worked on the first attempt. OE bump-stops included in the picture next to the new Sumo Springs.
Haven’t got to pull trailer yet, that’s why I bought them, but compared to the old ones, uh there’s no comparison, looking forward to pulling my trailer without worrying about how trailer is towing and not swaying
George, save where need be, This is the side By side for the Stock OEM bump stop on 2008 GMC Yukon XL
And the Sumo`s.
I have installed these on 3 GM products.
1.Great experience on a 2003 Tahoe, this made towing much more enjoyable. Reduced the porpoising of the vehicle driving down a highway. Also the vehicle doesn't drop as much when hooking up the trailer. Much improved towing experience. 5 stars
2. 2011 Suburban LTZ with airsprings. Noticed the difference but not as necessary. I do think it is better on the airsprings though when hooking up as the airsprings don't bottom out without the vehicle running. 5 stars
3. 2007 Escalade Had great difficultly installing. Just could not get them to pop into the socket fully. Wire brushed the sockets with an airtool. The clearance must be smaller, don't know. If this would have been my first install I would not have bought more of these. 1 star
I have a 2014 Yukon XL Denali and tow a 32ft camper trailer. I bought these helper stops as a cheap option to not have to replace my factory air ride system Not only was the price excellent, but the install was super easy(just use little lube and rubber mallet). I have towed our trailer many times since install and no issues, plus the existing air ride can still help level the load. Very please and would recommend this before expensive suspension upgrades
Ok, why didn't I buy these a few years ago?
They have no real impact at all on the ride of the truck unloaded, they go in place of the bump stops (if yours are more than five years old they're probably worthless anyway) and they really, REALLY stop the "squat" with a load on the ball - or in the back.
In addition, being that they take that load right on the frame essentially right where the springs do, there's no batter place to do that in terms of the original suspension and frame design.
I like 'em, assuming they hold up well.
Great love that the rear suspension doses not bottoms
I've ordered twice from this site and they are on it. Instant confirmation upon purchase as well as tracking info. Couldn't ask for a more seemless process.
My Chevy Tahoe does not sag as much when towing since installing these.
Rather difficult install. Not complicated, really, just a pain in the butt. Make sure you clean the housings, where the old ones are, after removal and before you put the new ones in. Really well.
The product seemed to work, but it would have been better if the product enguaged sooner instead of simply replacing the existing stop block.
easy to install, solved my dragging problem, was everything they promised awesome product, great price.
