This patented, self-lubricating design is exclusive to QA1 and is 100 percent owner rebuildable, with all internal parts replaceable at economical prices. Multiple stud lengths allow easy geometry changes, and infinite preload adjustment lets breakaway torque be set as low as 0 ft-lbs for smooth, bind-free operation. Precision tolerance ball-to-race conformity distributes load evenly for strong wear resistance, and a precision-ground 52100 bearing steel race delivers long life and smooth movement. The ball joint can be adjusted without removing it from the vehicle, which makes roll center tuning simple.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: QA1 Ultimate Ball Joint (adjustable, owner rebuildable)\u003c\/li\u003e\n\u003cli\u003eMounting style: Screw-In\u003c\/li\u003e\n\u003cli\u003eLocation: Upper\u003c\/li\u003e\n\u003cli\u003eApplication: Mopar\/NASCAR\u003c\/li\u003e\n\u003cli\u003eStud offset: -0.500in\u003c\/li\u003e\n\u003cli\u003eInternal race: precision-ground 52100 bearing steel\u003c\/li\u003e\n\u003cli\u003ePreload: infinite adjustment, breakaway torque from 0 ft-lbs\u003c\/li\u003e\n\u003cli\u003eDesign: patented, self-lubricating, 100 percent owner rebuildable\u003c\/li\u003e\n\u003cli\u003ePart number: 1210-300S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat is the QA1 part number for this ball joint?\u003c\/h5\u003e\u003cp\u003eThis listing is QA1 part number 1210-300S.\u003c\/p\u003e\u003ch5\u003eHow does this ball joint mount?\u003c\/h5\u003e\u003cp\u003eIt uses screw-in mounting and installs in the upper control arm location for Mopar\/NASCAR applications.\u003c\/p\u003e\u003ch5\u003eIs this QA1 ball joint rebuildable?\u003c\/h5\u003e\u003cp\u003eYes.
