UMI Performance Rear Adjustable Lower and Double Adjustable Upper Control Arm Kits

UMI Performance adjustable lower and double adjustable upper control arms are direct bolt-on replacements designed to minimize wheel hop. UMI Performance double adjustable upper control arms feature on-car adjustability, allowing for quick and easy pinion angle adjustment, and yes, it's as simple as loosening two nuts! The spherical rod end allows for a "bind-free" operation, making them great upgrades for both your track and autocross-driven vehicles. The polyurethane bushings are designed to be bolted to the chassis for quiet, comfortable operation. UMI Performance adjustable lower control arms are constructed from DOM mild steel tubing with a 1.500 in. o.d. x 0.120 in. wall and a 4130 chromoly threaded tube adapter. They are completely CNC-machined and fully TIG-welded for outstanding strength. The lower control arms also feature reinforced spring perches and heavy-duty sway bar mounting points. The upper control arms feature 0.250 in. mild steel mounting points, a 4130 chromoly tube adapter, and a 4140 chromoly heat-treated 1.120 in. solid adjuster--truly overkill. These control arms feature polyurethane bushings, zinc plated steel sleeves, and "on-car" greasable Zerk fittings. Adjustments can be made using the high-quality, PTFE-lined spherical rod ends for quiet, bind-free performance. Additional features include: * QA1 3/4 in. hard chrome plated, PTFE/KEVLAR® self-lubricating race rod end * CNC-machined 6061 aluminum step bushings with zinc plated steel sleeves * Powdercoated finish * Use OEM hardware Show Less
