The Koni Yellow Shocks and H&R Sport Springs Kit is a matched suspension system engineered to lower vehicle ride height and enhance dynamic handling.

Factory vehicle suspensions prioritize mass market ride comfort, creating excessive wheel gap and elevated center of gravity. Pairing externally adjustable dampening with lowering springs corrects high stock ride height and increases cornering response without the high cost of full coilovers.

  • Koni Yellow shocks featuring knob-adjustable dampening from street to race settings

  • H&R Sport springs engineered for lowered stance and handling performance

  • Matched shock and spring package

Turner Tip: Perform a complete four-wheel chassis alignment immediately following installation to ensure correct suspension geometry and prevent premature tire wear.
