This genuine Valley gearbox is built by Valley in the USA.  The gearbox provides superior quality and performance and has an industry leading reputation for reliability. Each unit is factory tested.

• Large capacity rubber diaphragm to allow expansion with heat and pressure to minimize water condensation.
• Input and Output bearings are American made and case hardened to provide the highest quality and load rating available in the industry to insure long trouble free life.
• Worm gear is high strength ductile iron to provide significantly longer wear life than steel when combined with a cast iron bull gear.
• Tooth design is industry exclusive 25 degree tooth angle which provides 40% longer life and better reliability in tough conditions compared to normal 14.5 degree tooth designs.
• Largest bull gear neck and keyway for strength
• Expansion chamber cap made of non-corrosive cast aluminium; rubber diaphragm allows oil to expand and contract during operation. Vented cap prevents pressure build-up which helps prevent seal leaks.
• Threaded endcap allows accurate bearing preload, to increase bearing life.
• 52:1 gear ratio, full recessed tooth design keeps lubricate engaged between gears.
• Bull gear, high strength cast iron provides the highest load capacity in the industry and longest life.
• Strongest gearbox housing, more material in high stress areas. Designed to distribute loads more evenly.
• Supplied with Valley Xtreme lube, a lubricate designed to support the long life of your pivot gearbox
• Longest output shaft (steel), exclusive to Valley gearboxes. Provides extra clearance between the gearbox and wheel flange, reducing mud build-up, resulting in reduced seal damage and supporting extended gearbox life.
