This Fabtech 1.5‑inch lift Ball Joint UCA system for 2019–2020 GM K1500 trucks pairs Dirt Logic 2.5 front coilovers with Dirt Logic 2.25 rear shocks to improve off‑road suspension performance while preserving a compliant highway ride. The kit uses ball‑joint upper control arms to retain proper ESC operation and ground clearance, simplifies installation, and balances front and rear damping for better handling and ride quality on varied terrain.
