The UMI 1" tubular rear sway bar for 1964–1972 GM A‑Body is a Pro‑Tour upgrade that reduces binding and sharpens handling. Designed to clear a wide range of rear ends, it offers three different rate settings and CNC‑machined clamping hardware for secure mounting. Included components such as greaseable polyurethane bushings and a billet hex adjuster support on‑car preload and long service life.
