# UMI Performance 99-04 Ford Mustang Upper & Lower Rear Control Arms Kit

The product description includes a complete kit with UMI Performance adjustable lower control arms and fixed length non-adjustable upper control arms. These direct bolt-on replacements are designed to minimize wheel hop, improve cornering, lower ET's, and enhance track consistency. The lower control arms are constructed from DOM mild steel tubing with a 4130 chrome-moly threaded tube adaptor, CNC machined, and TIG welded for exceptional strength. The spherical rod end allows for bind-free operation, while polyurethane bushings provide a quiet and comfortable ride. The upper control arms feature mild steel mounting points, DOM steel tubing, and polyurethane bushings. Both control arms include polyurethane bushings, zinc-plated steel sleeves, and greaseable zerk grease fittings for easy maintenance. Adjustments can be made using high-quality QA1 Teflon lined spherical rod ends for quiet performance. Additionally, the lower control arms feature reinforced spring perches and heavy-duty sway bar mounting points. Installation is easy with bolt-on installation that does not require drilling and uses OEM hardware.
