Product description

The JG447 is a heavy-duty 8-1/2" plunger assembly designed for Rotary in-ground lifts, featuring a specific 4-inch hole pattern for secure carriage mounting. As the moving heart of the hydraulic cylinder, the plunger is responsible for carrying the entire weight of the vehicle during operation. A damaged or scored plunger can cause significant seal wear and lead to internal hydraulic leaks that affect lifting capacity. This SVI replacement plunger is manufactured from high-strength steel and features a precision-ground surface to ensure smooth travel and a perfect seal interface. Replacing a worn plunger restores the mechanical stability of your lift and ensures that the vehicle remains level and secure throughout the lifting cycle.
