# RockJock JK Antirock Sway Bar Kit Rear Forged Arms Heavy 1 1/8in Bar

Overlanders and Racers! RockJock heard you and the wait is over! Their heavy bar Antirock Sway Bar Kit for the rear of all Jeep JK Wrangler models features a 1 1/8 in. diameter, 28 spline bar! This heavier bar considerably increases the rate of the rear sway bar for those with racks, roof top tents, camping gear, etc. This heavy bar kit is also applicable to desert racing applications. This kit easily bolts on with hand tools and is designed to directly replace the vehicle's stock rear sway bar. The sway bar is made of 4130 heat treated chromoly for ultimate strength, which is the same quality used in professional off-road competition sway bars. The Antirock rear sway bar, when used in conjunction with a front Antirock sway bar, provides a more stable feeling cabin and balanced performance of front and rear suspension in rugged off-road conditions. Antirocks gives the driver increased traction by balancing and distributing the weight and traction over all four tires.
