The XRAY 372190 front coil springs are intended to give X12 drivers more control over suspension behaviour. Designed for 4mm kingpin axles, the set spans a range of spring rates to help you adjust handling for different track conditions. The powder-coated finish makes each spring easy to distinguish at a glance.
Changes in wire diameter and coil count alter spring stiffness, represented by the "C" number. Incremental steps let you refine front weight transfer and steering response without guessing.
Powder-coated colours provide instant recognition of each rate, helping you keep consistent runs and reducing time spent searching for the right part during pit sessions.
