The Fabtech 6-inch RTS raised torsion suspension system for 2011–2019 GM 2500HD with DLSS shocks uses a patent-pending bracket system to retain torsion bars in stock position and improve ground clearance. The kit includes unitized bracketry, heavy-duty crossmembers, and skid protection to resist front suspension impacts, and is intended for off-road durability while maintaining proper suspension geometry and highway manners.
