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

Progressive spring for precise drift 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 dialing in drift angles and transitional control without aggressive low-speed harshness. Quantity: 2pcs.
