UMI Performance Rear Control Arms and Panhard Bar Kits
UMI Performance Rear control arms and panhard bars are direct bolt-on replacements designed to minimize wheel hop and improve cornering and track consistency, while lowering ETs. The control arms are constructed from a DOM mild steel tubing 1.375 in. o.d. x 0.095 in. wall and are completely CNC-machined and fully TIG-welded for outstanding strength. The adjustable models feature spherical rod ends that allow for "bind-free" operation, making them great upgrades for both your track and autocross-driven vehicles. The Roto-Joint equipped models are designed to work like a spherical rod end while maintaining the qualities of a softer bushing. Roto-Joints feature a 4140 chromoly ball that rotates in a Delrin race. Additional features include: * Control arms are 1.375 in. x 0.095 in. mild steel tubing * 4130 chromoly threaded tube adapter (adjustable models only) * 3/4 in. hard chrome plated PTFE/KEVLAR® self-lubricating race rod end * TIG-welded construction * CNC-machined 6061 aluminum step bushings with zinc plated steel sleeves (where applicable) * Polyurethane greasable bushings * On car grease fittings (except rod ends) * Use OEM hardware

UMI Performance On-Car Single Adjustable Panhard Bars
UMI Performance on-car single adjustable panhard bars control the side-to-side movement of the rear-end under the vehicle. The flex and bushing deflection found with the factory panhard bar lead to erratic handling and tire rubbing under hard loads. UMI Performance on-car single adjustable panhard bars use polyurethane bushings and a heavy-duty spherical rod end and are constructed from large 1.250 in. diameter tubing. Adjustable panhard bars are a must for rear-end centering after vehicle lowering, as well as clearance for running larger tires. The supplied rod end allows for adjustments on the car to quickly lengthen or shorten the panhard bars--they do not need to be removed to make adjustments. The spherical rod end/polyurethane bushing combination eliminates most rear-end bind, while not sacrificing your ride quality. These panhard bars are an excellent improvement for your street or drag application and they are also lighter then the factory panhard bars!

UMI Performance control arm torque box reinforcements will take care of those cracked torque boxes. If you have raced your Mustang aggressively, on slicks, or even on the street, and especially if your car is a 5-speed, you may have cracked torque boxes. Fox bodies don't have the best chassis to begin with; combine them with a V8 and some torque, and you are going to have problems. That is why control arm reinforcements or torque box reinforcements were designed to reinforce weak and cracked torque boxes.
