When a trailer or heavy gear pushes down on the rear suspension, the Hellwig EZ-550 Helper Springs add up to 500 lbs of load-leveling capacity to keep your truck sitting level. Mounted above the factory leaf springs, they prevent sagging and help maintain proper braking and steering response under light towing or hauling. The extra support also helps extend the life of your original suspension, tires, and brakes.
Rough roads and uneven loads can make the ride unstable. These helper springs flex with your existing leaf pack to minimize bounce and reduce body roll so the truck stays steady through turns and over bumps. You’ll notice less sway when hauling gear or pulling a small trailer, which makes every mile feel more controlled.
Every haul is different, and these springs let you fine-tune for each one. The included U-bolts can be adjusted to match varying weight or uneven cargo from side to side. You can set each spring independently so both sides of the truck carry their share, keeping the bed level whether you’re loaded evenly or not.
There’s no need for complicated fabrication or shop time. The EZ-550 bolts above your factory leaf springs using zinc-plated hardware that resists corrosion. With its simple bolt-on design, you can install it in your own driveway using basic hand tools and be ready to tow or haul with better stability in short order.
Work trucks take a beating, so construction matters. These helper springs are made from strong steel with a silver vein hammer tone powder coat finish that stands up to rust and wear. They’re built for long-term performance so you can count on consistent support season after season.

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at this Hellwig EZ-550 Above Axle Helper Springs for the small GM trucks. Now, this is a custom fit part. It is designed to fit the 2015 and newer Chevrolet Colorado and GMC Canyon trucks. And on a custom fit part like this, I do like to recommend for you go to our website, use the fit guide, put in your year and model of vehicle, and it'll show if this a work for your application.
Now, these are light duty custom helper springs that upgrade your factory leaf springs to reduce any sway and body roll. These will prevent sagging when you're towing or hauling light loads, and it helps extend the life of your factory suspension, tires and brakes. Now, these will flex with your leaf springs to limit bouncing, while providing optimal stability. And the U-bolts, if we zoom in on those. You can see these U-bolts here, they can be adjusted to suit different loads.
And also, the drivers and passenger sides can be adjusted independently for uneven loads. Now, this is a very easy install. It'll bolt above your factory leaf springs. All the mounting hardware, as you can see, is included. Comes with a nice set of instructions.
It is a durable steel construction, ensures long-lasting performance. And I just also wanna zoom in on the finish on these. If you look real close, it uses a silver vein hammer toned powder coat finish to resist rust and corrosion, plus give it a good look. Now, these parts are made in the USA. Weight capacity on this is 500 pounds.
One thing I do wanna mention is Hellwig Helper Springs will not increase your vehicle's weight carrying capacity. But that should do it for the review on the Hellwig EZ-550 Above Axle Helper Springs for the small GM trucks.

Glad to hear they are helping, Thomas! Looks like you have a pretty good amount of weight back there as well, so that's quite the compliment! ^___^ What kind of bike is that? Couldn't tell from the picture.
