JK ALUMINUM Mid Arm Kit - REAR ONLY

The Artec JK Aluminum Mid Arm Kit — Rear replaces the rear control arms on a Jeep Wrangler JK with 7075-T6 polished aluminum links: 2.0-inch OD lowers and 1.5-inch OD uppers. For the past several years Artec has run 7075-T6 aluminum links in its ARTECON test rig to prove they can survive both extreme rock crawling and daily driving, while shedding significant weight compared to standard steel tubing.
