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

Progressive drift spring for tuning

This is an R/C-scale progressive drift spring intended for tuning drift setups and fine‑tuning suspension response on model drift cars. Supplied as a pair, the springs use a progressive wind pattern so small wheel movements feel softer while larger deflections increase spring rate, helping manage slide transition and chassis balance during drifting practice.

Installation is a direct swap into compatible coil‑over style shock assemblies that accept internal springs; install in matched pairs and verify spring seating and preload before running. As with any suspension change, test incrementally and adjust preload or shock valving to re‑balance the chassis rather than relying solely on spring changes.

Use these springs when you want a smoother initial bite with a predictable ramp‑up in resistance under deeper compression, useful for dialling in drift angles and transitional control without aggressive low‑speed harshness. Quantity: 2pcs.
