The Yokomo B9-SLF270A front linear shock spring, co-developed with AXON for the BD9 series, features an equal pitch coil that sharpens steering and refines cornering control. Its linear characteristics reduce understeer compared with factory progressive springs, helping drivers hit tighter lines with confidence.
Because it is 1.5mm shorter than earlier models, this spring avoids the need to modify shock ends when altering vehicle height. It is versatile enough for front or rear use depending on tyre selection and track surface, offering a practical upgrade for competitive setups.
