Poly bushings reduce deflection, while reinforced sway bar mounts add strength. Bolt-on arms minimize wheel hop, improve cornering.\u003c\/p\u003e\n\u003ch3\u003eDetails\u003c\/h3\u003e\n\u003cp\u003eRear control arms are essential suspension upgrades for GM vehicles. Stock control arms are prone to bushing deflection and rusting, leading to traction loss and poor handling. Our boxed control arms offer improved performance for both weekend cruising and track use. The included polyurethane bushings outperform OEM rubber, enhancing ride quality and reducing traction loss. These direct bolt-on control arms minimize wheel hop, enhance cornering, and promote track consistency. They are designed with provisions for both stock and aftermarket sway bars, with reinforced sway bar holes for added durability. Constructed with 0.120\" wall thickness rectangular tubing, CNC machined bushing holders, and MIG welded end caps for protection against road debris. Installation is straightforward, using OEM hardware and taking approximately 1 hour. Detailed installation instructions are included for convenience.\u003c\/p\u003e\n\u003ch3\u003eDescription\u003c\/h3\u003e\n\u003cp\u003eBoxed rear control arms boost handling, traction, and durability.\u003c\/p\u003e\n\u003ch3\u003eShort Description\u003c\/h3\u003e\n\u003cp\u003eControl Arms\u003c\/p\u003e\n\u003ch3\u003eApplication Summary\u003c\/h3\u003e\n\u003cp\u003eUMI designed 3021 to fit 1978-1988 GM G-Body\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt with 0.120\" Wall Thickness Rectangular Mild Steel Tubing\u003c\/li\u003e\n\u003cli\u003eCNC Machined for Precision Tolerances and Accuracy\u003c\/li\u003e\n\u003cli\u003eMIG Welded DOM Steel Bushing Holders\u003c\/li\u003e\n\u003cli\u003eGrease-able High Quality Bushings with Grease Fittings\u003c\/li\u003e\n\u003cli\u003eDurable Long Lasting Powder Coat finish\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\u003e3021-R\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 Trailing 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\u003eEach\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003ctd\u003e16.0 lb\u003c\/td\u003e\n\u003ctd\u003eL 24.0 x W 6.0 x H 6.0 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\u003eNo\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\u003eRed\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\u003ePolyurethane\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 -
