Kings Springs use high quality, high stress X5K spring steel. This new generation steel allows King Springs to further improve many of their existing designs by reducing the amount of steel required in a spring, making it substantially lighter (by approximately 30%) and reducing the solid height therefore increasing travel.
These King Spring lowering kits will lower all listed models 30mm both Front and Rear.
Note: For i30 PD models, King Spring recommend trimming the bump stops 20mm
