UMI’s 1" solid rear sway bar for 1964–1972 GM A‑Body vehicles reduces body roll and understeer for improved cornering and launch stability. Made from heat‑treated 4140 CrMo and formed as one piece to retain shape and memory, it ships with Grade 8 hardware and is available in bright red or gloss black powder coat. Note: aftermarket Ford 9" installations may face a drain‑plug guard fitment issue.
