Upgrade Your Ride with Stifflers' '05-'14 Mustang Convertible Rear Chassis Brace!

Check out our all-new '05–'14 Mustang Convertible Rear Chassis Brace! The original OEM brace was weak, prone to rust, and has been discontinued from Ford. Stifflers Convertible Rear Chassis Braces is the smarter and stronger solution that has been engineered to integrate into the lower torque box, making this product a first of its kind in the industry!

Designed with strength, durability, and real-world performance in mind, our brace increases chassis stiffness over the OEM brace—improving ride quality and handling, especially when you’ve got the top down.

Direct integration into the lower control arm torque box for added structural support

Enhanced suspension predictability for a more confident driving experience

Sealed tubing construction—no rust issues like the OEM factory brace

Durable powder-coat finish for long-lasting good looks

This isn’t just an upgrade—it’s a game-changer for every ’05-’14 Mustang Convertible owner.
