SKU TJ3011, the ones with the guid plates for alignment. I purchased these even though there going on with CORE4X4 adjustable control arms. CORE arms are set up for factory style lower control arm brackets and they recommended these brackets when asked what was going to work best. SKU TJ3011 for our 03 WRANGLER TJ 4.0 5spd with DANA 30 up front. Laser etching for alignment plate installation on the brackets makes them easy to welding on in position. The brackets fit onto the differential tube flawlessly and are a snap to get into position for welding. My MILLER 140 with .035 wire handled the job with no trouble. These are heavy duty brackets with plenty of protection for the control arm ends. They are not going to colaps or bend like the factory brackets or the light duty less expensive replacement brackets out there.
