If using a front 1 ton swap kit, you'll need to extend your frame side trackbar bracket forward to clear that larger axle. This bracket makes this easy by keeping most of the stock bracket and just trimming some of it rather than removing it completely.
Features include:

• 3/16 inch mild steel. Precision CNC cut and bent for great fitment.
• Designed from 3D files directly from Jeep for a precision fit around frame and existing trackbar bracket
• Needed for 1 ton swaps in JL and JT

Notes:

• This kit requires general welding and fabrication skills. Welding should only be done by a competent welder. Artec Industries implies no guarantees or warranties and is not liable for improper installation.
• Some grinding and fitment may be required when installing this kit. Every axle varies slightly and some fabrication may be required.
