What is the main benefit of upgrading the rear sway bar?

Upgrading to a larger, stiffer rear sway bar like this one from Progress Technology significantly reduces body lean during cornering. This helps keep your tires in better contact with the road, improving grip and driver confidence.

What material is the sway bar made from?

The sway bar is constructed from alloy steel. It is a solid bar, not hollow, and features polyurethane bushings for improved stiffness over stock rubber components.

Does this sway bar come with all the necessary hardware for installation?

This product includes the adjustable rear sway bar itself. Installation typically involves reusing some stock hardware, but it's always best to consult the manufacturer's installation guide for a complete list of required components and tools.

Subaru Impreza 2004-2007

Product Details

When you're looking to get a better feel for your 2004-2007 Subaru Impreza on the road, this rear sway bar from Progress Technology is a solid option. It's designed to replace the stock bar and its softer rubber bushings with a larger diameter alloy steel bar and harder polyurethane bushings. This setup adds more roll stiffness to your suspension, which means less body lean when you're cornering. Less lean helps keep your tires flatter and more connected to the pavement, giving you more grip and better control.

This sway bar is 22mm in diameter and is adjustable, allowing you to fine-tune how your car handles. Progress Technology makes these bars in-house using CNC bending equipment, and the ends are precisely welded for a good fit. By upgrading your rear sway bar, you can help reduce the understeer that many modern cars experience, leading to a more balanced and confident driving experience.
