RockJock offers optional machined lightweight billet aluminum arms for Antirock sway bar kits for the hardcore rock crawling crowd. These arms are modified for use on the front of the Jeep TJ Wrangler and LJ Unlimited when using our CE-9900 Antirock sway bar kit. Arms are CNC machined from 3/4 in. thick 6061T6 aluminum, are 18 in. in length, and weigh just 1.5 pounds compared to the 3.5 pound weight of the standard steel arms. The aluminum arms feature the same 5 adjustable link mounting holes that the steel arms feature. Price above is for a pair of aluminum Antirock arms.
