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: 4-Bolt\u003c\/li\u003e\n\u003cli\u003eLocation: Upper\u003c\/li\u003e\n\u003cli\u003eApplication: GM\u003c\/li\u003e\n\u003cli\u003eCross-reference: K6136\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: 1210-203B\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1975 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1976 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1977 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1978 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1979 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1980 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1981 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1982 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1983 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1984 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1985 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1986 Chevrolet C10\u003c\/li\u003e\n\u003cli\u003e1973 Chevrolet C10 Pickup\u003c\/li\u003e\n\u003cli\u003e1974 Chevrolet C10 Pickup\u003c\/li\u003e\n\u003cli\u003e1973 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1974 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1975 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1976 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1977 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1978 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1979 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1980 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1981 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1982 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1983 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1984 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1985 Chevrolet C10 Suburban\u003c\/li\u003e\n\u003cli\u003e1986 Chevrolet C10 Suburban\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 1210-203B.\u003c\/p\u003e\u003ch5\u003eHow does this ball joint mount?\u003c\/h5\u003e\u003cp\u003eIt uses 4-bolt mounting and installs in the upper control arm location for GM applications.
