Product Description

The Whiteline KSB729 Rear Chassis Support Brace is engineered to reinforce the rear frame structure on S197 generation Ford Mustang models from 2005 through 2014. This heavy-duty boxed steel brace replaces the lightweight stamped factory support and dramatically increases rigidity around the rear panhard rod area. By reducing chassis flex and load stress, it helps keep suspension alignment angles consistent under heavy acceleration, braking, and cornering loads, resulting in sharper handling and more predictable vehicle dynamics.

Designed specifically for Mustang coupes and convertibles - including base, V6, GT, Boss 302, Bullitt, Shelby GT, and Shelby GT500 models - the KSB729 provides a simple bolt-on upgrade with no welding or cutting required. It's especially effective when paired with an upgraded heavy-duty panhard bar (e.g., Whiteline KPR037) to further enhance rear suspension stability. Finished in durable powder coating and backed by a 3-year limited performance warranty from Whiteline, this chassis support brace is ideal for street, track, and performance-oriented builds seeking improved rear chassis stiffness and handling feedback.
