The RockJock 4x4 Antirock Sway Bar Kit provides balanced performance of front and rear suspension for rugged off-road conditions. It gives the driver increased traction by balancing and distributing the weight over all four tires. The Anitrock Off Road Sway Bar is designed to replace the stock Jeep sway bar. 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.
