Once it collapses, the control arm shifts under load and steering feedback turns mushy right when you need it most. The SuperPro DURO3739K DuroBall bushing set replaces that worn OE rubber with a metal-and-polyurethane hybrid pivot that locks the control arm's geometry in place and keeps the front end tracking exactly where you point it.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDuroBall technology combines a precision metal ball joint with a polyurethane boot for OE-style articulation without the deflection\u003c\/li\u003e\n\u003cli\u003eCorrects the vertical pivot weakness built into the factory rubber bushing design\u003c\/li\u003e\n\u003cli\u003ePolyurethane blend resists oil, grease, and road grime that cause premature rubber failure\u003c\/li\u003e\n\u003cli\u003eSharper, more direct steering response under hard cornering and trail braking\u003c\/li\u003e\n\u003cli\u003eReduces unwanted control arm movement for consistent alignment settings\u003c\/li\u003e\n\u003cli\u003eDirect bolt-in replacement using the factory mounting location\u003c\/li\u003e\n\u003cli\u003eMPN DURO3739K is engineered specifically for the Evo's front lower inner rearward mount, not a universal fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eTrim\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2003-2006\u003c\/td\u003e\n\u003ctd\u003eMitsubishi\u003c\/td\u003e\n\u003ctd\u003eLancer Evolution\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2005-2006\u003c\/td\u003e\n\u003ctd\u003eMitsubishi\u003c\/td\u003e\n\u003ctd\u003eLancer Evolution\u003c\/td\u003e\n\u003ctd\u003eMR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2005-2006\u003c\/td\u003e\n\u003ctd\u003eMitsubishi\u003c\/td\u003e\n\u003ctd\u003eLancer Evolution\u003c\/td\u003e\n\u003ctd\u003eRS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2006\u003c\/td\u003e\n\u003ctd\u003eMitsubishi\u003c\/td\u003e\n\u003ctd\u003eLancer Evolution\u003c\/td\u003e\n\u003ctd\u003eSE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMPN\u003c\/td\u003e\n\u003ctd\u003eDURO3739K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSuperPro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePosition\u003c\/td\u003e\n\u003ctd\u003eFront Lower Inner Rearward\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePolyurethane with metal DuroBall pivot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKit Contents\u003c\/td\u003e\n\u003ctd\u003e3-piece vehicle set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eLifetime warranty on SuperPro polyurethane bushings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003eNot published by manufacturer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1x SuperPro DURO3739K front lower inner rearward DuroBall bushing set (3-piece vehicle kit)\u003c\/li\u003e\n\u003cli\u003ePolyurethane DuroBall bushings with dust boot covers\u003c\/li\u003e\n\u003cli\u003eInstallation hardware included with the kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAbout SuperPro\u003c\/h4\u003e\n\u003cp\u003eSuperPro has manufactured performance polyurethane suspension bushings since the 1970s, engineering replacement components that correct the inherent weaknesses of factory rubber bushings.
