When your fifth wheel landing gear stops responding or grinds on the way down, the gearbox is often the culprit. The Lippert 276602 is a direct-replacement aluminum gearbox engineered for universal mount landing gear assemblies used on fifth wheel trailers. It restores full landing gear function without replacing the entire leg assembly -- saving time, money, and shop labor.
The 276602 gearbox slots into Lippert universal mount landing gear systems used across a wide range of fifth wheel brands. If your landing gear is struggling to extend or retract, making grinding noises, or has completely failed, this aluminum gearbox is the serviceable component most likely to restore operation. At just 5 lbs., it ships quickly and installs with basic hand tools.
This part is also cross-referenced by major OEM RV manufacturers under their own part numbers, making it one of the most widely applicable landing gear gearboxes in the fifth wheel segment.
Lightweight yet durable aluminum housing stands up to road vibration, weather, and the repetitive load cycles of daily travel use.
Designed specifically for Lippert universal mount landing gear legs found on hundreds of fifth wheel trailer models from multiple manufacturers.
Also fits select Atwood and Stromberg Carlson electric landing gear assemblies, making it useful for multi-brand service and parts inventory.
Ships ready to install with minimal prep. No specialized tools or machining needed for a standard DIY replacement job.
