Swapping an LS engine into a classic GM A-body is nothing new. UMI Performance LSX engine mounts allow the installation of an LS engine directly into your A-body. By retaining the proper angle of the engine, you keep your pinion angles/drivetrain operating smoothly. This is a good reason to get pre-engineered mounts for the swap instead of trying to make something work. These mounts place the engine in the factory location, but also give you the ability to relocate the engine rearward up to 3/4 in. or forward 1/4 in. UMI's LS engine mounts will bolt directly to your car's frame and the LS block without modifications. Their brackets have greasable polyurethane mounts to dampen vibration, but still provide a solid feel and eliminate the need for additional modification when using the LS1 oil pan. New premium mounting hardware is also included. Getting a quality set of mounts designed for your application will definitely make the swap a lot easier

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!
