A smart suspension upgrade project shouldn't stop after coilovers or lowering springs.

Sway bars are a perfect compliment, and a must for any good suspension upgrade project. 

ST suspension is a sister company of KW.

All of their products are engineered and manufactured to the same high standards as KW.

Made of high tensile strength spring steel.

ST sway bars reduce body roll and improve road grip and cornering.

Precision engineered to provide the best performance possible, ST sway bars are cold formed then powder coated for lifetime durability.

Kits come complete with new urethane sway bar bushings and any necessary hardware for a quick and easy installation.
