QA1 79-04 Mustang Rear Sway Bar

Want to increase your vehicle’s grip and improve handling and stability of your Mustang? QA1’s lightweight tubular sway bars are engineered to reduce body roll by evenly distributing the weight of your vehicle across all four tire contact patches during cornering. This upgrade provides improved stiffness for a more predictable and stable driving experience.

Performance Tuned for Your Vehicle

Size matters when it comes to sway bars. QA1 engineers its tubular sway bars specifically for each vehicle application, tuning the diameter and tubing wall thickness to generate the torsional stiffness needed for superior ride control. The rear sway bar is built using solid 1" 4130 chromoly steel for superior stiffness and strength, and features a compact design optimized for space and ground clearance.

Installation Made Simple

QA1 sway bars are designed with both form and function in mind, offering superior performance in an easy-to-install package, often using factory sway bar mounting locations. Some installations may require simple welding, but QA1 provides detailed instructions and expert technical support for all levels of experience.
