That is why we have taken the  time to develop the Ultimate \"on car\" adjustable upper control  arms for the rear on your GM  vehicle. There were no short  cuts when manufacturing these  arms, only the best materials  and components money can buy  were used to build our \"Ultimate Arms\". Well known  weak areas where other  manufactures use mild steel have  been replaced with aircraft  quality 4140 chromoly steel  featuring a TIG welded  construction. The upper control  arm mounting points feature CNC  machined 0.250\" mild steel, 4140  Chrome-Moly tube adaptors and a  high strength 4140 chromoly  heat treated 1.000\" solid  adjuster; truly overkill for  any application!\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":47862860939522,"sku":"UMI3017-R","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/3017-r.jpg?v=1784962600","url":"https:\/\/www.lethalperformance.com\/products\/umi-performance-78-87-gm-g-body-adjustable-upper-control-arms-ultimate-arms-1","provider":"Lethal Performance","version":"1.0","type":"link"}
