This Ball Joint is Sold Individually\r\r\r\rThere’s nothing worse than snapping a lower ball joint on your Polaris. Whether you drove it too hot into a curb, smacked a rock, or went full-send mode and landed a jump too aggressively, an OEM ball joint for side-by-sides is prone to failure. Fortunately, Black Ops Machine has the high-quality replacement Heavy Duty Ball Joint to resolve this common issue.\r\r\r\rOur HD ball joints are engineered for the off-road enthusiast who doesn’t have time for broken OEM suspension parts. This heavy-duty ball joint replacement part follows Polaris OEM fitment standards, with upgraded materials and precision manufacturing standards to hold up to constant abuse.\r\r\r\rBlack Ops Machine solves common Polaris ball joint issues by using 4340 chromoly and 300m steel on the housing, support cup, and stud. The dust boots are upgraded with CR/reoprene, with a 6061-aluminum designed adjustment plate cap.\r\r\r\rWhile we strongly prescribe to the "fix it all at the same time" mentality when it comes to replacing ball joints, we sell this product individually. So – to avoid further ball joint failure – replace them all at the same time – cool?
