Housing Narrow Dbl Shear Birdcage

The WEHRS MACHINE Housing Narrow Double Shear Birdcage (model WM200-1NDS) is a precision-engineered shaft housing designed for high-performance driveline applications where compact envelope and extreme durability are non-negotiable. Built with a 3.000-inch inner diameter and double-shear design, this component is engineered to handle significant load transfer while maintaining tight tolerances critical to off-road performance, racing, and specialty vehicle platforms.

Construction is 4140 alloy steel finished in black oxide, a time-proven surface treatment that resists corrosion while maintaining precise dimensional stability under extreme temperatures and shock loads. The housing ships complete with ring clamps and integrated bearing surfaces, eliminating the need for sourcing additional components. The double-shear architecture distributes stress across dual load paths, reducing single-point failure risk—a critical advantage in vehicles operating at the edge of mechanical capability. At 5.18 lbs and compact 6.5-inch cubic dimensions, the unit delivers serious structural capacity without adding unnecessary weight or packaging complexity to tight installations.

This housing is the choice for fabricators, race shops, and off-road builders demanding OEM-quality components with the durability to outlast routine maintenance cycles. Whether for high-horsepower transmission upgrades, custom driveline builds, or replacement during overhauls, the WEHRS MACHINE birdcage housing delivers engineering integrity that justifies the investment. The included ring clamps and bearings mean installation crews can move forward without hunting for matching components or worrying about specification mismatches.
