What is the benefit of an adjustable rear sway bar?

An adjustable rear sway bar allows you to fine-tune your truck's handling characteristics. By changing the position, you can adjust how much the bar resists body roll, helping to reduce understeer or oversteer and achieve a more balanced feel during cornering.

Yes, this UMI Performance rear sway bar kit includes all the necessary mounting hardware. However, be aware that minor drilling may be required for installation on some vehicle applications.

Product Details

If you're looking to significantly improve the cornering performance and stability of your classic GM C10 squarebody truck, this adjustable rear sway bar from UMI Performance is a solid choice. Designed for trucks from 1973 through 1987, this sway bar helps reduce body roll, allowing your truck to handle much flatter through turns. It's a popular upgrade for those who want a more connected feel to the road, whether you're cruising daily or participating in events like Power Tour.

This bar is constructed from a stout 1-inch diameter steel, offering a strong foundation for improved handling. What really sets it apart is the three-position adjustability, which lets you fine-tune the sway bar's stiffness to match your driving style and the specific setup of your truck. This adjustability is key to dialing in the perfect balance, especially when paired with a front sway bar like UMI's 6440 model. UMI Performance builds these bars in the USA, and they include all the necessary mounting hardware to get them installed. While most of the installation is straightforward, be aware that minor drilling may be required for some applications.

This rear sway bar is a well-built component that can make a notable difference in how your C10 feels on the road. It's designed to be a direct fit for a wide range of GM C10 and GMC C1500 models from the mid-70s to the late 80s, including popular examples like the 1975-1986 Chevrolet C10 and the 1987 GMC R1500. All the mounting hardware you'll need is included in the box, making it a complete package for upgrading your truck's suspension.
