Steeda Mustang Extreme G-Trac Brace
The Extreme G-Trac brace links the rear of the front subframe to points close to the control-arm mounts. This more direct load path reduces flex and helps maintain suspension geometry under cornering loads. It uses chrome-moly alloy-steel tubing, which Steeda describes as more than twice as strong as mild steel.
The kit includes the brace and installation hardware. Bolt-on construction clears long-tube headers. Updated part 555-5536 replaces 555-5532, which is still shown in some product videos.
