Spring Cup 5in Short Swivel OD Alignment

The WEHRS MACHINE Spring Cup 5in Short Swivel OD Alignment (Model WM485s) is a precision bolt-on drop bearing assembly designed for high-performance suspension systems requiring reliable upper control arm articulation. Built from steel with a durable black paint finish, this component supports 5-inch springs and delivers the controlled angular compliance needed in demanding vehicle applications where exact alignment geometry directly impacts handling, tire wear, and cornering stability.

At 2 inches in height, the spring cup's compact profile accommodates tight suspension packaging while the swivel OD design enables precise load distribution across the bearing surface. The bolt-on installation method eliminates welding, allowing straightforward integration into existing suspension frames without thermal distortion or metallurgical compromise. Weighing 1.95 lbs, the assembly contributes minimal unsprung mass while maintaining the structural rigidity required for vehicles experiencing sustained lateral loads or multi-axis articulation during off-road travel, high-speed cornering, or racing environments where suspension geometry consistency is non-negotiable.

This component serves fabricators, suspension engineers, and enthusiasts building or refurbishing independent suspension systems—particularly those optimizing upper control arm mounting for drag racing, road racing, rock crawling, or engineered off-road platforms. The 5-inch spring compatibility positions this bearing for mid-travel applications where spring rate and suspension travel balance under varied load conditions. WEHRS MACHINE spring cups are recognized for precision manufacturing tolerances that maintain consistent preload and reduce lateral play, translating directly to predictable suspension response and extended component lifespan in high-cycle environments.
