When your RV slide-out room stops extending or retracting cleanly, a worn or damaged drive shaft is often the culprit. This genuine Lippert outer X-shaft tube is the OEM-matched replacement -- cut to 72 inches, pre-drilled, and ready to drop into Lippert slide-out systems that use the 1 in. square X-shaft drive configuration.
Lippert slide-out systems are found across hundreds of RV brands and floorplans -- from fifth wheels and travel trailers to Class A and Class C motorhomes. The outer X-shaft is a core component of the horizontal drive assembly, transferring torque from the motor/gearbox through to the slide room rack. This part carries Lippert part number 117630 and matches the factory specification for systems using a 1 in. x 1 in. square-profile shaft at the 72-inch length.
The pre-drilled holes allow for the attachment of drive pins, set collars, or hardware that locks the shaft into the slide mechanism -- preserving the OEM mounting interface so you are not cutting or modifying a raw tube in the field. Using a genuine Lippert shaft means consistent wall thickness, correct material hardness, and confidence that your slide room will cycle reliably for seasons to come.
1 in. x 1 in. square-profile X-shaft matches factory Lippert drive specifications exactly -- no shimming or adapting required.
Factory hole pattern preserves the OEM pin and collar mounting interface, saving significant labor time during installation.
Ships at the full 72 in. working length to fit the widest range of slide-out room widths in this shaft class.
Sourced directly from Lippert. Part number 117630 matches the factory BOM for compatible slide-out drive systems.
In a Lippert electric slide-out system, the X-shaft (also called the outer drive shaft or cross shaft) spans the width of the slide room and is driven by a gearmotor mounted on the room frame. As the motor turns, it rotates the X-shaft, which drives the slide room in or out along its rack or cable system. The "outer" designation refers to the shaft's position in two-piece or telescoping shaft assemblies -- the outer tube receives the inner shaft, allowing the drive assembly to adjust as the room travels.
Because this shaft is under constant rotational and bending load every time the slide cycles, wear, corrosion, or physical damage from road debris or improper storage can cause binding, incomplete travel, or complete drive failure. Replacing the shaft with a correct-spec OEM part restores smooth, full-travel operation.
This shaft is used in Lippert electric slide-out systems across a wide range of OEM RV manufacturers including Forest River, Coachmen, Keystone, Heartland, Jayco, Starcraft, and others that sourced Lippert slide-out hardware. Verify your existing shaft dimensions -- specifically the 1 in. x 1 in. square profile and approximately 72-inch working length -- before ordering.
Shaft replacement typically requires two people -- one to support the slide room and one to work the drive assembly. Retract and block the slide room before beginning. Disconnect motor power before removing any drive components. Transfer all existing collars, pins, and hardware from the old shaft to the new shaft, aligning with the pre-drilled hole pattern. Cycle the room slowly on first use to confirm proper alignment before normal operation.
