        abstract = {This paper presents the design and analysis of a four-link suspension system incorporating nested helical coil springs for the rear axle of a military truck. Traditional leaf springs were replaced with a coil spring-based suspension to enhance wheel travel and improve off-road mobility. Detailed design calculations were carried out based on SAE spring design manuals and IS standards. A rigid axle of 7-ton capacity was adapted to a four-link suspension with two coil springs per side. The spring dimensions, stiffness, stress values, and fatigue life cycles were determined. Load distribution across suspension components was calculated, and a multi-body dynamic simulation was performed using MSC ADAMS/Car to analyze wheel travel and camber variations. Results demonstrated improved ride comfort, higher roll stiffness, and enhanced mobility in cross-country terrains.},
