Product description

The front plunger is the heart of your in-ground lift's power, and this 8-1/2" diameter unit is built to deliver heavy-duty performance for Rotary systems. 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.
