Product description

The JG451 is a precision-manufactured 8-1/2" plunger replacement for Rotary in-ground lifts, engineered with a 6-inch bolt circle for carriage mounting. This plunger is the primary moving element that converts hydraulic pressure into the lifting force needed to service modern vehicles. Over decades of use, the external surface of a plunger can become scratched or pitted, which leads to hydraulic fluid weeping past the seals and a messy work environment. SVI's replacement is built to exacting tolerances, ensuring a tight fit and smooth travel throughout the lift's entire range of motion. Upgrading to a new plunger during a major lift service restores the factory-spec performance and helps prevent premature wear on other hydraulic components.
