Upper Spring Cup 5in OD Spring 10pk

The Upper Spring Cup 5in OD Spring 10pk from ALLSTAR PERFORMANCE is a precision suspension component engineered for high-performance vehicles requiring robust spring locating and support. This bolt-on upper spring cup assembly is essential for maintaining proper spring geometry and load distribution in demanding applications—whether you're building a track vehicle, off-road rig, or upgrading factory suspension. The ten-pack format makes this solution ideal for fleet maintenance, shop inventory, or multi-vehicle builds where consistency and reliability across all installations matter.

Constructed from steel with a durable black powder coat finish, the Upper Spring Cup 5in OD Spring 10pk accommodates 5-inch outer diameter springs and stands 3.25 inches tall—dimensions engineered to work within standard suspension architecture while maintaining proper preload and ride height. The bolt-on design eliminates welding requirements, allowing rapid installation and replacement without permanent modification to chassis components. Black powder coating provides corrosion resistance and extends service life in harsh weather, salt, and high-vibration environments typical of tactical, military, and heavy-use vehicles. Each cup is precision-manufactured to exacting tolerances, ensuring uniform spring seat surfaces that prevent binding and uneven wear.

Operators and technicians managing custom suspension systems, military vehicle fleets, or high-duty-cycle platforms benefit most from stocking this ten-pack configuration. The bulk packaging reduces per-unit cost while ensuring availability for ongoing maintenance schedules. Installation is straightforward: bolt the cup to the existing spring perch, verify alignment, and torque fasteners to manufacturer specification. Compatibility spans most independent and coil-over suspension designs accepting standard 5-inch diameter springs; confirm mounting surface dimensions and bolt hole pattern against your specific platform before ordering.
