The Yokomo YOKYS2DLH is a 2mm long shock spring intended for drift RC setups, supplied in green and produced by Swift. It serves as a basic tuning item to alter suspension response by adjusting spring rate and preload without changing shock oil or piston options.
Fit this spring as either a replacement part or a tuning upgrade on compatible drift shock assemblies. Changing springs is a standard tuning approach to influence how the car rolls and exits slides: softer springs promote roll and absorb transfers, while firmer springs limit roll and speed up recovery.
Installation is conventional: remove the shock from the model, disassemble the cap and shaft per your shock type, slide the spring onto the shock body or shaft retainer cup, then reassemble. Check spring retainer and end cap clearances prior to refitting and carry out cautious testing after adjustments.
Compatibility notes: this product is an aftermarket spring for drift use. Always confirm fitment with your shock's seat height and inner diameter before buying, as these vary by manufacturer.
