This 1" solid rear sway bar from UMI targets 1964–1972 A‑Body cars to cut body roll and improve cornering balance. Constructed from heat‑treated 4140 chromoly and formed as a single piece, the bar resists deformation and ships with new Grade 8 hardware. Offered in red or black powder coat, it’s a focused upgrade for stability and control; check Ford 9" aftermarket housings for potential drain‑plug guard interference.
