UMI Performance’s  adjustable upper controls feature on car adjustability and are supplied  with spherical Roto-Joints. 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  installed 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. The installed delrin race, which lines the spherical  ball, absorbs shock and road noise for a quiet and smooth operation on  any street or track driven vehicle.\u003cbr\u003e\u003cbr\u003eUMI Performance bump steer kits relocate the outer tie rod pivot point which results in decreased toe change during wheel travel. Standard kits include sleeves, rod ends, jam nuts and high quality, direct fit tapered studs. Race kits require drilling of the spindle and include heavy duty 5\/8 bolts. Race kits are recommended for autocross and road race applications while standard kits are indicated for street\/strip use.\u003cbr\u003e\u003cbr\u003e","brand":"UMI Performance","offers":[{"title":"Default Title","offer_id":47862871523586,"sku":"UMI3624-R","price":319.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/00034524a9098728d9a897c5e7e0e750.jpg?v=1785861002","url":"https:\/\/www.lethalperformance.com\/products\/umi-performance-91-96-impala-ss-adjustable-extended-length-upper-control-arms-roto-joints-1","provider":"Lethal Performance","version":"1.0","type":"link"}
