Aluminum Mid Arm Kit (Front 3-Link) for Jeep Wrangler JK 2007-2018

This version of Artec's JK Aluminum Mid Arm Kit covers the whole Jeep with the front set up as a three-link: machined 7075-T6 aerospace-grade aluminum links replace the heavy steel arms on a 2007-2018 Jeep Wrangler JK or JKU, cutting meaningful unsprung and rotating weight while keeping the strength to survive hard rock crawling. A single upper up front frees packaging and articulation compared to the factory dual-upper layout, and every link threads onto a rebuildable Rock Krawler Krawler Joint so caster, pinion angle, and axle centering stay adjustable on the vehicle.

Features

• Four 2.0" OD 7075-T6 polished aluminum lower links
• Front converted to a single-upper 3-link; one LH Rock Krawler 7/8" UCA U-bracket with stud included
• Rock Krawler Krawler Joints: 1.25"-12 tpi x 9/16" on the lowers (4 RH, 4 LH), 7/8"-14 tpi x 9/16" on the uppers (3 RH, 2 LH), all with jam nuts
• Wrench flats and threaded ends for on-vehicle length adjustment
• Direct replacement for factory-style steel Rock Krawler mid-arm links
• Rust-proof aluminum skips the repaint cycle bare steel links need
• Field-tested for years in the ARTECON under crawling and daily driving

Designed to run with Artec's 1-ton axle swap and factory-style 4-link geometry using Daystar or Johnny Joint bushings. To finish the front 3-link conversion, plan on the JK HD Crossmember with Link Mounts, the JK Front 3-Link Frame Mount Bracket, and an Adjustable Truss Upper Link Mount, all sold separately.
