AST astAST-150-340-61

The AST linear race spring is a single 150 mm coil spring with a 340 N/mm rate and a 61 mm inner diameter, designed for coilover-style suspension when extremely high spring rates are required to change ride height and stiffness. Sold individually, it supports focused tuning with heavy damping choices; make sure the 61 mm inner diameter fits your coilover assembly before ordering.
