The Yokomo YOKYS2DLH is a 2mm long shock spring intended for drift RC setups, supplied in green and produced by Swift. It is a straightforward tuning part that changes suspension response by altering spring rate and preload behavior without modifying shock oil or pistons.
Use this spring as a replacement or tuning option on compatible drift shock assemblies. Swapping springs is a common way to fine-tune how quickly a car rolls into and recovers from slides; softer springs increase body roll and absorb weight transfer, while stiffer springs reduce roll and speed up recovery.
Installation is standard: remove the shock from the car, disassemble the shock cap and shaft as required by your shock design, slide the spring onto the shock body or shaft retaining cup, and reassemble. Verify clearance with spring retainers and end caps before final reinstallation. Always test on a safe surface after changes and adjust other suspension elements as needed to re-balance handling.
Compatibility notes: this part is specified for drift use and functions as an aftermarket spring option. Confirm fitment with your shock length and retainer style before purchase, since spring seat height and inner diameter vary by shock maker.
