Description: This kit includes a set of rear lower control arms and a on car adjustable panhard bar. These items feature polyurethane bushings on one end and UMI's spherical Roto-Joint on the other end. This set up is designed for street performance and street enthusiast. The polyurethane bushing end is designed to be bolted to the vehicle chassis side while the Roto-Joint attaches to the rear end side. Since the polyurethane bushings are softer they are designed to absorb more road noise and shock before it enters the passenger compartment of the vehicle. The Roto-Joint design is a pivot ball lined with a greaseable delrin race designed to offer 28 degrees of total unrestricted movement, more than adequate for a bind free, low friction operation UMI 203337-R 82-02 F-Body Lower Arms & Panhard Bar Roto, Red Sku # 185203337R Mfr.

These items feature polyurethane bushings on one end and UMI's spherical Roto-Joint on the other end. This set up is designed for street performance and street enthusiast. The polyurethane bushing end is designed to be bolted to the vehicle chassis side while the Roto-Joint attaches to the rear end side. Since the polyurethane bushings are softer they are designed to absorb more road noise and shock before it enters the passenger compartment of the vehicle. The Roto-Joint design is a pivot ball lined with a greaseable delrin race designed to offer 28 degrees of total unrestricted movement, more than adequate for a bind free, low friction operation. The Roto-Joint design improves performance over the factory rubber and aftermarket polyurethane bushings by allowing the suspension to articulate correctly, and provide precision handling. The included panhard bar is a must for rear end centering after vehicle lowering, as well as clearance for running larger tires. The supplied CNC machined double adjuster features left and right hand threads for quick and easy on car adjustments by simply loosening two jam nuts, the panhard bar does not require removal to adjust. The spherical Roto-Joint/polyurethane bushing combination eliminates most rear end bind while not sacrificing ride quality making this is an excellent improvement on any street or drag application. All bushing ends and Roto-Joints are greaseable and low maintenance making an excellent street setup for your cruiser! Features: Constructed of DOM mild steel tubing Spherical Roto-Joints installed 4140 chromoly, heat treaded on car adjuster Energy Suspension greaseable polyurethane bushings Kit is fully TIG welded Shipped fully assembled and ready to install Uses OEM hardware Brilliant and durable powder coat finish More about Roto-Joint Technology: UMI's Roto-Joint, short for Rotational Joint, allows 28 degrees of total rotation and unrestricted movement throughout the vehicles suspension. The Roto-Joint is designed to work like a spherical rod end while maintaining streetable qualities of a softer bushing. The Roto-Joint is designed to articulate and prevent suspension bind, and since the installed delrin race does not deflect like softer bushings, there is an improvement in traction and a significant reduction in wheel hop. The construction of the Roto-Joint features a 4140 chromoly, hard chrome plated spherical ball which rotates in a delrin race. The 4140 chromoly material and hard chrome plating are designed for extensive wear resistance against hard driving and accumulated miles. The spherical ball rotates in the CNC machined delrin bushing, which is contoured for the spherical ball to allow unrestricted movement as the ball rotates. Delrin is the bushing material of choice due to its high resistance against wear, great tensile strength, and ability to maintain its physical properties. The housing of the Roto-Joint features 4140 chromoly threads, and a CNC machined bushing holder TIG welded together for the utmost in strength and durability. The UMI Roto-Joint is adjustable and 100% rebuildable. This means as the delrin race wears the adjuster ring can be tightened using the optional spanner wrench to apply tension to the ball. If the delrin race would ever wear completely it can be replaced easily. Spanner Wrench: This spanner wrench is used for adjusting and disassemble of Roto-Joints used in all UMI Performance products. Over time if the delrin race inside the Roto-Joint would wear the spanner wrench is used to tighten the adjusting ring applying more pressure to the delrin inside. The spanner wrench is also used to disassemble the Roto-Joint for cleaning, inspection and rebuilding.
