For 1997-2006 Jeep TJ's and Unlimited's. The Currie Antirock® Sway Bar Kit with aluminum arm option provides balanced performance of front and rear suspension for rugged off-road conditions as well as a light weight, trick looking aluminum arms. It gives the driver increased traction by balancing and distributing the weight and traction over all four tires. The Antirock® Off Road Sway Bar is designed to directly replace the stock Jeep sway bar and is an easy bolt on installation. The sway bar is made of SAE 4130 Heat-treated steel for ultimate strength. This is the same quality used in professional off-road competition sway bars. The Currie Antirock® Sway Bar does not need to be disconnected for off-road use. CAUTION: Jeeps will have more body roll than stock. This sway bar may be used on the street however, it will not provide the same performance as the stock setup.
