When you’re towing a camper or hauling a full bed of gear, rear-end sag can throw off your handling and braking. The Hellwig EZ-550 Helper Springs add 500 lbs of load-leveling capacity above your factory leaf springs to keep your ride level and steady. They prevent sagging when towing or carrying light loads so your steering feels solid and your headlights stay aimed where they should.
Heavy loads can make a truck sway or bounce over bumps. These custom helper springs flex with your factory leaf springs to reduce body roll and limit bounce while maintaining stability. The U-bolts are adjustable so you can fine-tune the setup for different loads and driving conditions, keeping the truck planted when roads get rough or uneven.
Uneven cargo can make one side of your vehicle squat lower than the other. Each Hellwig EZ-550 Helper Spring can be adjusted separately on the driver and passenger sides to level things out. That means better control, even when hauling gear that’s off-center in the bed or trailer tongue weight that pulls harder on one side.
Installing suspension support shouldn’t require a lift or special tools. These helper springs bolt directly above your rear factory leaf springs using the included zinc-plated mounting hardware. The bolt-on design makes for an easy install in your driveway with basic tools—no drilling or cutting needed.
When you depend on your suspension every day, reliability matters. The EZ-550 Helper Springs are built from durable steel with a silver vein hammer tone powder coat finish that resists corrosion. This setup extends the life of your factory suspension, tires, and brakes so you can keep hauling without worrying about wear or rust down the road.

The Hellwig EZ-550 Helper Springs didnt work out for me. When my 2021 Tacoma wasnt loaded the ride was to stiff and the bed sat to high. I have since installed SUMO Springs and they have worked well for my occasional haulingtowing and do not affect normal unloaded driving.

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.
