82-02 Fbody UMI Performance On Car Adjustable Panhard w/Roto-Joint


Model Number: 2037
UMI Performance

This tubular on car adjustable panhard bar replaces the flimsy stock stamped panhard bar while adding increased strength and rear end adjustment. This 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. The installed Roto-Joint is a pivot ball lined with a greaseable delrin race designed to offer 28 degrees of total unrestricted movement. The Roto-Joint design improves performance over the factory rubber and aftermarket polyurethane bushings by allowing the suspension to articulate correctly, and provides precision handling. The UMI Roto-Joint allows rear end free movement when high handling, auto cross or road race is a concern while still being a 100% streetable setup. This is an excellent upgrade for any application.

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 chrome moly, hard chrome plated spherical ball which rotates in a delrin race. The 4140 chrome moly 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 chrome moly 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 disassembling 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.

    noticable increase in rear suspension stiffening. wheel hop is gone. 166k miles on the stock suspension and this was a great improvement. also purchased the matching control arms. wish i upgraded earlier
