Currie now offers optional machined lightweight aluminum arms 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 machined out of 6061T6 3/4"-thick aluminum, are 18" 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.
