RockJock Antirock rear sway bar kit for JK Wrangler 2-door models uses an SAE 4130 heat-treated steel bar sized for two-door applications and is a direct bolt-on replacement for the stock rear sway bar. When used with a front Antirock bar it helps balance traction and weight distribution across all four tires. The kit installs without the need to disconnect for off-road use.
