This kit is for the serious enthusiast, it includes UMI’s Roto-Joints on all ends for maximum performance, extreme handling and no bushing deflection. The installed Roto-Joint design improves performance over the factory rubber and aftermarket polyurethane bushings by allowing the suspension to articulate correctly. 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 installed delrin race, which lines the spherical ball, absorbs shock and road noise for a quiet and smooth operation working well on the street and at the track. The included panhard bar is a must for rear end centering after vehicle lowering, as well as clearance for running larger tires. It features on car adjustability using left and right hand threaded Roto-Joints. Adjustment of the panhard bar is made by simply loosing two jam nuts and turning the bar to shorten or lengthen it. This double adjustable panhard bar features chrome moly tube adapters TIG welding into place for the utmost in strength and thread durability. All bushing ends and Roto-Joints are greaseable and low maintenance making an excellent street setup for your cruiser!

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 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.
