Steeda's S550/S650 Mustang Extreme G-Trac Brace (k-member brace) for 2015+ Mustang GT, EcoBoost, and V6 is a direct bolt-on addition to your Mustang and provides greatly improved front chassis bracing.

Steeda's S550 Mustang Extreme G-Trac Brace for 2015+ Mustang GT, EcoBoost, and V6 mounts close to the control arm mounts, and helps strengthen the connection between the control arm mounts, and the rear of the subframe. This makes the load path more direct, and gives much more effective stiffening, so the suspension geometry does not change during high cornering/chassis loads. Manufactured from super strong chrome moly, alloy steel tube, making it over twice as strong as any mild steel offering.

Note: This brace does not fit 2018 and newer EcoBoost with A10 auto trans or GT350. GT350 owners should purchase 555-5533 and 2018+ Ecoboost owners should purchase 555 5534.
