Constructed of 14-gauge steel box tubing, these subframe connectors significantly increase an F-body's performance and handling capability. Choose between bolt-on or weld-on connectors. The bolt-on version is powdercoated gloss black and utilizes existing mounting points (no holes to drill). The unfinished weld-on design must be painted after installation. Tubing is 2"x2", 1"x1", and 2"x3" with 1/4" steel plates.
