19- GM P/U Rear Sway Bar 1-1/8in

The HELLWIG 19-GM P/U Rear Sway Bar 1-1/8in (Part #7780) is a performance-engineered suspension component designed specifically for 2019–2023 GM full-size pickup trucks. This adjustable rear sway bar delivers measurable improvements in cornering stability and body roll control, making it the go-to upgrade for drivers who want tighter handling without compromising ride quality on highway or back road driving.

Built from chromoly steel and finished in gray powder coat, the 1.125-inch diameter bar reduces lateral weight transfer during aggressive cornering and lane changes. The adjustable design allows you to fine-tune suspension compliance to match your driving style and load conditions—whether you're towing, hauling cargo, or running empty. At 52.36 lbs, this sway bar adds minimal unsprung weight while delivering significant stiffness where it counts. The kit includes all necessary brackets and hardware for a direct bolt-on installation with no fabrication required.

This upgrade is ideal for truck owners seeking better handling in curves, reduced body lean during loaded towing, and improved overall chassis balance. Rear sway bars work by resisting the natural tendency of the truck's body to roll outward during cornering, distributing suspension loads more evenly between the rear wheels. The result is more predictable handling, faster steering response, and greater confidence when navigating mountain passes or dodging obstacles at highway speed.

HELLWIG has established a strong reputation for suspension performance in the truck aftermarket. Their adjustable sway bars are engineered to integrate seamlessly with OEM suspension geometry while delivering tunable stiffness for diverse real-world applications. This rear sway bar for 2019–2023 GM pickups represents a straightforward, proven upgrade path for anyone looking to improve handling dynamics without overhauling the entire suspension system.
