UMI boxed weld‑in subframe connectors for 1982–1992 GM F‑Body models are a heavy‑duty chassis upgrade for hardtop, T‑top and convertible cars, built to minimize flex during racing or hard driving. Using 2.000" x 1.250" x 0.120" rectangular mild steel and CNC‑machined 0.188" mounting points, the three‑piece design creates six major weld locations for extreme stiffness. Precision MIG welded and powder coated, the weld‑in kit installs permanently and includes hardware and instructions.
