JK ALUMINUM Mid Arm Kit - Lowers Only

The Artec JK Aluminum Mid Arm Kit — Lowers Only swaps the factory lower control arms on the Jeep Wrangler JK for polished 7075-T6 aluminum links with RockKrawler joints. It adds style and articulation on a budget, using aluminum that Artec proved out over roughly five years of ARTECON rock crawling and daily-driver testing.

Key Features

• Four 2.0" OD 7075-T6 polished aluminum lower links
• Eight RockKrawler joints: 4 RH and 4 LH, 1.25"-12 tpi with a 9/16" hole
• Eight matching 1.25"-12 tpi jam nuts (4 RH, 4 LH)
• 7075-T6 aluminum for a strong link that saves weight over steel tubing
• Validated through years of ARTECON race and trail abuse

Fitment & Compatibility

Fits the Jeep Wrangler JK and JKU (2007-2018), two-door and four-door. This kit covers the lower control arms only; the upper arms are retained. The links replace the OEM lowers and bolt to the factory frame and axle mounting points.

Frequently Asked Questions

What does "lowers only" include?
The four lower control arm links (front and rear) with RockKrawler joints and jam nuts. The upper arms are not part of this kit.

Which Jeep does it fit?
The Jeep Wrangler JK and JKU (2007-2018), both two-door and four-door, using the factory lower control arm mounts.

Why 7075 aluminum?
7075-T6 is a high-strength aerospace alloy that trims weight versus steel tubing while taking rock-crawling abuse, which Artec validated in the ARTECON.

Can I adjust the arm length?
Yes — the RockKrawler joints thread onto the 1.25"-12 tpi links and lock with the supplied jam nuts for setup.
