Ironman 4x4 Rear Coil Springs (Pair) – Constant Load 300kg GVM, 45mm Lift – TOY056C

Ironman 4x4 Rear Coil Springs (Pair) – TOY056C

Built for vehicles that carry heavy loads every day, the Ironman 4x4 TOY056C rear springs provide a 45mm lift and are rated to support a constant rear load of 300kg or more. These heavy-duty springs are intended for professional and industrial applications—construction, forestry, trade tools, permanently installed overland gear, and more.

Important: These springs are not recommended for vehicles without a consistent heavy load. Using them in an unloaded or lightly loaded state may result in reduced comfort, poor handling, and unsafe driving behavior.

With approximately 30% stiffer handling than OEM springs, they deliver robust support and a firm, planted feel. When paired with Ironman 4x4 shock absorbers, they offer reliable suspension performance even in harsh worksite or off-road environments.

Questions & Answers
