Specifically designed to replace the JG437 reference, this plunger features an 83-3\/8\" overall length, providing the necessary stroke for a full range of vehicle service. Over years of operation, plungers can develop scoring or pitting that leads to hydraulic leaks and inconsistent lifting speed. This SVI International replacement is manufactured with a precision-ground surface to ensure a perfect seal with the packing glands, restoring smooth and reliable lifting power to your bay. It is a fundamental component for shops looking to rebuild their Rotary in-ground lifts to original performance levels.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Performance Lifting:\u003c\/strong\u003e Engineered for maximum hydraulic efficiency and load-bearing capacity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Ground Surface:\u003c\/strong\u003e Features a smooth, durable finish to minimize friction and extend seal life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-Duty Construction:\u003c\/strong\u003e Built from high-grade steel to resist bending and structural fatigue under load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExact OEM Dimensions:\u003c\/strong\u003e Matches the JG437 specifications perfectly for a drop-in installation during lift rebuilds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliable Longevity:\u003c\/strong\u003e Designed to withstand the high-cycle demands of a busy commercial service department.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Reference:\u003c\/strong\u003e JG437\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 8-1\/2\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length:\u003c\/strong\u003e 83-3\/8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSVI Part Number:\u003c\/strong\u003e BH-9770-50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eDirect replacement models\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotary:\u003c\/strong\u003e JG437\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSVI International:\u003c\/strong\u003e BH-9770-50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Models:\u003c\/strong\u003e Compatible with Rotary AC60E, AC60H, AP50E, and AP50H in-ground lift models requiring a JG437 plunger.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThis item can be found in:\u003c\/strong\u003e Rotary AC60E, Rotary AC60H, Rotary AP50E, Rotary AP50H\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eYou will receive the same product or an OEM-Equivalent that meets the highest standard of the OEM with warranty that will be a direct-fit.
