King Springs Unrivaled Reputation.

Engineered and manufactured to the highest standards at their state of the art facility in Australia. King Springs are the longest running and most trusted spring on the market for Subaru’s. The advanced manufacturing produces a spring with better load capacity, increased comfort and off road capability.

Reduces sway and body roll.

Improves your vehicles handling capability, especially after you raise your cars center of gravity from lifting it.

Designed for street and off-road use.

King Springs are slightly stiffer than your stock springs but won’t create a harsh ride. This is paramount for towing or when equipped with roof top or bumper mounted accessories. Examples include tents, bikes, kayaks, spare tires, gas can, etc. The springs will help the car from bottoming out.
