Skyjacker 4-inch suspension system for 1973–1987 GM three‑quarter‑ton trucks with 56‑inch springs provides lift and improved clearance while aiming to preserve a controlled ride. The components come with mounting hardware and installation instructions to aid fitment and are designed for typical on‑ and off‑road use; some setups will require additional parts to complete the full suspension conversion.
