Keep your RV slide-out room operating smoothly with the correct OEM-spec replacement drive shaft from Lippert. Part number 116656 is a precisely dimensioned shaft measuring 0.625 inches in diameter and 11.75 inches in length, engineered to fit Lippert slide-out drive systems found in a wide range of travel trailers and fifth wheels.
Lippert Components is the dominant supplier of slide-out room mechanisms in the North American RV industry, and many repairs come down to a single worn or damaged drive shaft. Part 116656 restores proper operation without the guesswork of aftermarket substitutions -- the 0.6250-inch diameter and 11.7500-inch length are exact OEM specifications, ensuring correct engagement with the drive gear, rack, and coupling hardware in compatible Lippert assemblies.
Whether your slide-out is slow, grinding, or not extending fully, the drive shaft is a common wear item worth inspecting before replacing larger assemblies. Using the correct replacement shaft maintains proper torque transfer and protects surrounding components from stress caused by a misfit part.
0.625 in. diameter x 11.75 in. length matches Lippert factory specification for compatible slide-out drive assemblies.
Sourced directly from Lippert Components under part number 116656 -- not an aftermarket approximation.
Designed to drop into compatible Lippert slide-out mechanisms without modification to mounting hardware or couplings.
Corrects slide-out extension and retraction issues caused by a worn, bent, or broken drive shaft in the affected assembly.
Lippert slide-out systems use precise shaft-to-gear engagement tolerances. An undersized or oversized diameter -- even by a few thousandths -- can cause premature gear wear, noise, or binding. Using the exact Lippert 116656 shaft preserves those tolerances and protects the motor and rack components downstream.
Lippert manufactures multiple slide-out system types including Schwintek in-wall systems, rack-and-pinion systems, and hydraulic-assist systems. The 116656 shaft applies to specific mechanical drive configurations. Confirm your system type and existing shaft dimensions before ordering. The shaft diameter (0.6250 in.) and length (11.7500 in.) are the key match points.
If the original shaft is already removed or damaged beyond measurement, reference your RV's Lippert slide-out documentation or the tag on the slide-out motor assembly to confirm the correct part number. Installing a shaft of incorrect length can prevent full engagement or cause the slide to bind at the end of travel.
When replacing the drive shaft, inspect the drive coupling, gear housing, and any set screws or roll pins that retain the shaft. Replacing worn retention hardware at the same time prevents a repeat failure and ensures the new shaft seats and locks correctly under load.
