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

Adjustable progressive spring designed for drift control

This R/C-scale progressive drift spring is intended for tuning drift setups and tailoring suspension response on model drift cars. Supplied in pairs, the progressive wind pattern keeps small deflections pliant while adding rate under greater compression to aid slide management and chassis equilibrium during practice.

They are a direct swap into coil-over type shock assemblies that accept internal springs; fit both springs together and check seating and preload prior to running. As with any suspension modification, proceed in small steps and adjust damping or preload to maintain balance rather than relying purely on springs.

These springs give a gentler initial bite with predictable ramping in resistance for improved drift angle control and smoother transitions without harsh low-speed behavior. Quantity: 2pcs.
