A direct OEM-spec replacement hydraulic cylinder for the 2016 Alpine Ram slideout system. Built with an aluminum body, 1.5 inch bore, and a 2200 PSI pressure rating, this cylinder delivers the force and durability needed to extend and retract heavy slideout rooms reliably. If your current cylinder is leaking, bent, or failing to hold position, this is the exact-fit replacement Lippert specifies for this application.
Lippert hydraulic slideout systems use dedicated cylinders matched to the stroke length and bore diameter required by each slideout room's geometry and load. Swapping in the wrong bore size or stroke length results in incomplete extension, uneven room movement, or hydraulic system overpressure. Part number 339031 is spec'd specifically for the 2016 Alpine Ram -- no adapters, no modifications.
The 1.5 inch bore provides the cross-sectional area needed to generate sufficient force under Lippert's standard hydraulic operating pressure. The aluminum body keeps weight down compared to steel alternatives while still handling the 2200 PSI system pressure rating without distortion or leakage over time.
Designed specifically for the 2016 Alpine Ram slideout -- matches OEM mounting points, stroke length, and porting without modification.
Handles the full operating pressure of Lippert hydraulic slideout systems without risk of seal failure or cylinder distortion.
Lightweight aluminum construction with a 1.5 inch bore delivers strong extension and retraction force while minimizing added weight on the chassis.
Full 24 inch stroke matches the slide travel distance of the specified Alpine Ram room -- critical for complete extension and flush retraction.
Hydraulic slideout cylinders are not universal. The stroke determines how far the room travels, and the bore determines how much force the cylinder can produce at a given system pressure. Installing a cylinder with a shorter stroke leaves the room partially extended. A larger or smaller bore changes the force balance and can cause the room to rack or move unevenly if multiple cylinders are used in tandem.
Always replace with the exact stroke and bore specified for your slideout. For the 2016 Alpine Ram, that is the 24 inch stroke, 1.5 inch bore cylinder -- which is exactly what part 339031 delivers.
Replacement of a Lippert hydraulic slideout cylinder is a straightforward mechanical job for a competent DIYer with basic hydraulic experience. The general process involves relieving system pressure, disconnecting hydraulic lines at the cylinder ports, unbolting the cylinder from its mounting brackets, installing the new cylinder, reconnecting lines, and bleeding the system. Torque hydraulic fittings to Lippert specifications to prevent seepage.
