When towing or hauling pushes your truck past what the factory suspension can comfortably manage, rear-end sag and instability quickly become a problem. Hellwig Pro Series Helper Springs are designed to solve that issue for 2019–2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks by adding real load support without sacrificing everyday drivability.
Built for light-duty trucks that work hard, these helper springs help maintain proper ride height under load, which directly improves control, braking confidence, and overall stability.
Why the GM 1500 Platform Benefits from Helper Springs
The Silverado 1500 and Sierra 1500 are well-known for strong performance and reliability, but like most half-ton trucks, they rely on a single rear leaf spring pack across all trims and configurations. When weight is added—whether from a trailer, bed cargo, or equipment—the factory springs can struggle to keep the truck level.
Hellwig Pro Series Helper Springs add supplemental rear support, helping the suspension carry weight more effectively without replacing the factory leaf pack.
What Makes Hellwig Pro Series Helper Springs Different
The Pro Series Helper Springs (P/N 61917) replace earlier designs and are now compatible with all trim levels of the 2019–2020 Silverado 1500 and Sierra 1500. This updated design gives drivers more flexibility and more control over how their truck handles weight.
- Rated for up to 2,500 lbs of load-leveling support
- Two-leaf helper spring pack for adjustable spring rate
- Allows tuning based on the weight being towed or hauled
- Silent ride bushings for quiet operation under load
- Independent side-to-side adjustment for uneven loads
This adjustability is especially useful for trucks that see varying loads, letting drivers dial in support instead of relying on a one-size-fits-all solution.
Real-World Benefits You Can Feel
Keeping the truck level isn’t just about appearance. Proper ride height plays a major role in how a truck handles when loaded.
- Improved stability when towing or hauling
- More consistent steering and braking response
- Reduced rear-end sag under load
- Better tire contact and more even tire wear
- Less stress on factory suspension components
By supporting the rear suspension, Hellwig helper springs help the truck stay controlled instead of feeling overloaded or unsettled.
Installation and Build Quality
Hellwig Pro Series Helper Springs are designed for straightforward installation using basic hand tools. Each kit includes all required hardware and mounts directly to the factory suspension without permanent modification.
Manufactured in the USA, Hellwig helper springs are built from high-quality steel and backed by a lifetime warranty on all steel components. This makes them a solid long-term solution for trucks that regularly tow or haul.
A Smart Upgrade for Working GM 1500 Trucks
If your Silverado 1500 or Sierra 1500 is frequently tasked with towing trailers or carrying heavy cargo, Hellwig Pro Series Helper Springs provide a practical way to improve load control and stability. They deliver the extra rear support these trucks need to stay level, predictable, and confident under real-world conditions.
