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

Tunable progressive spring for drift setups

This R/C-scale progressive drift spring is built for tuning drift setups and adjusting suspension response on dedicated drift models. Sold as a pair, the progressive coil profile delivers softer reactions for small displacements and ramps up stiffness under larger compressions to aid slide control and chassis balance.

Fitting is a straightforward swap into coil-over style shocks that accept internal springs; always install both sides as a matched set and check that springs seat correctly and preload is even before track use. Make incremental changes and retune shock valving if needed to restore balance.

Ideal when you want a gentler initial bite that increases predictably with travel, helping you hold drift angles and manage transitions without harsh low-speed feedback. Quantity: 2pcs.
