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.\u003c\/p\u003e\u003cp\u003eThis product may expose you to chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.\u003c\/p\u003e","brand":"UMI PERFORMANCE","offers":[{"title":"Default Title","offer_id":51782476661048,"sku":"U01C 4036-B","price":232.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-362220-5873033-square.webp?v=1779237847","url":"https:\/\/store.motormia.co\/products\/umi-performance-68-72-a-body-non-adjustable-upper-control-arms-w-roto-joint-1","provider":"MOTORMIA","version":"1.0","type":"link"}
