Yokomo YOKD171G Progressive Drift Springs 1.3 x 9.5 Hard Green (2pcs)  [YOKD171G]

Progressive coil spring to refine drift handling

This progressive R/C drift spring is designed for tuning drift setups and refining suspension feel on model drift cars. Packaged as two springs, the progressive winding provides a soft initial response that increases stiffness on deeper travel, which helps with slide transitions and chassis composure during extended drifts.

They install as a direct replacement in coil-over style shock units that accept internal springs; always fit matched springs, confirm correct seating and preload, and perform break-in checks before running. Incremental testing and tuning of preload or shock valving is recommended rather than relying solely on spring changes.

Choose these springs when you want a smooth initial bite and a predictable ramp-up in resistance for better transitional control without aggressive low-speed feedback. Quantity: 2pcs.
