Here is the boot lift cylinders (also called rams), all of our lift cylinders are completely new and are made as exact replacements for your car. We do not sell 'universal' or rebuilt rams, all of our cylinders are backed with a 3 year warranty when not used with brake fluid. We also have a page under the 'TECH HELP' button with everything you need to know about hydraulic convertible top systems, it is a must read if you are replacing your top cylinders, lines or pump. This cylinder fits 1956-62 Corvette convertible car. This is the cylinder for the boot, not the cylinder for the convertible top. One needed per car.
