AST astAST-130-140-61

The AST linear race spring is a single 130mm coilover spring with a 140 N/mm rate and a 61mm inner diameter. Its linear profile preserves a consistent spring rate through travel so tuners can dial predictable handling and ride height on coilover-equipped vehicles. Sold individually as part of AST’s Linear Race range, it offers a focused option for corner-weighting and suspension tuning.
