Our Ultimate \"on-car\" adjustable upper control arms for the rear of your GM vehicle have been meticulously designed with the best materials and components available. We have replaced weak areas with aircraft quality 4140 Chrome Moly steel and utilized TIG welded construction for maximum durability. These control arms feature high quality QA1 spherical rod ends for a smooth and quiet operation. The Teflon lined rod ends prevent metal to metal contact, eliminating unwanted noise. The on-car adjustability of our Ultimate Arms makes it easy to make pinion angle adjustments, whether in the garage or at the track. With UMI's unique Chrome Moly on-car adjuster, you can quickly lengthen or shorten the control arm length with just two jam nuts. Pinion angle adjustments are essential for improving track 60-foot times, increasing traction, and reducing wheel hop. The bind-free operation of our rod ends makes them a great upgrade for both track and auto cross driven cars. Trust only the best-QA1 for long lasting performance.\u003c\/p\u003e\n\u003ch3\u003eDescription\u003c\/h3\u003e\n\u003cp\u003eUMI Ultimate rear uppers: adjustable, durable, and precision-engineered.\u003c\/p\u003e\n\u003ch3\u003eShort Description\u003c\/h3\u003e\n\u003cp\u003eUpper Control Arms\u003c\/p\u003e\n\u003ch3\u003eApplication Summary\u003c\/h3\u003e\n\u003cp\u003eUMI designed 3617 to fit 1978-1996 GM B-Body vehicles.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUltimate \"on car\" adjustable upper control arms\u003c\/li\u003e\n\u003cli\u003eMade from aircraft quality 4140 Chrome Moly steel\u003c\/li\u003e\n\u003cli\u003eTIG welded construction\u003c\/li\u003e\n\u003cli\u003eCNC machined 0.250\" mild steel upper control arm mounting points\u003c\/li\u003e\n\u003cli\u003e4140 Chrome Moly tube adaptors\u003c\/li\u003e\n\u003cli\u003eHigh strength 4140 Chrome Moly heat treated 1.000\" solid adjuster\u003c\/li\u003e\n\u003cli\u003eSupplied with high quality QA1 spherical rod ends\u003c\/li\u003e\n\u003cli\u003eAlloy steel, heat treated, hard chrome plated rod ends\u003c\/li\u003e\n\u003cli\u003eTeflon\/Kevlar self lubricating race in rod ends\u003c\/li\u003e\n\u003cli\u003eOn-car adjustability for ease of adjustment\u003c\/li\u003e\n\u003cli\u003ePinion angle adjustments for track performance\u003c\/li\u003e\n\u003cli\u003eSuitable for track and auto cross driven cars\u003c\/li\u003e\n\u003cli\u003eBind free operation for smooth performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Info\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:12px;\"\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e3617-B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:12px;\"\u003ePart Type\u003c\/th\u003e\n\u003ctd\u003eSuspension Control Arm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:12px;\"\u003eHS Code\u003c\/th\u003e\n\u003ctd\u003e8708807000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:12px;\"\u003eCountry of Origin\u003c\/th\u003e\n\u003ctd\u003eUS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eAvailable Packages\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003ePackage\u003c\/th\u003e\n\u003cth style=\"text-align:left;\"\u003eQty\u003c\/th\u003e\n\u003cth style=\"text-align:left;\"\u003eWeight\u003c\/th\u003e\n\u003cth style=\"text-align:left;\"\u003eDimensions\u003c\/th\u003e\n\u003cth style=\"text-align:left;\"\u003eGTIN\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBox\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003ctd\u003e9.0 lb\u003c\/td\u003e\n\u003ctd\u003eL 14.0 x W 6.0 x H 4.0 Inches\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:12px;\"\u003eAdjustable\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:12px;\"\u003eBushing Color\u003c\/th\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:12px;\"\u003eBushing Material\u003c\/th\u003e\n\u003ctd\u003eRod End Bearing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:12px;\"\u003eBushings Included\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:12px;\"\u003eCalifornia Proposition 65\u003c\/th\u003e\n\u003ctd\u003eWARNING: Cancer and Reproductive Harm -
