Bump Spring Cup

The Bump Spring Cup from SWIFT SPRINGS is a precision-engineered suspension component designed to support and stabilize bump stop assemblies in vehicle suspension systems. This single-spring cup serves as a critical interface between the bump stop spring and the vehicle frame or suspension arm, absorbing compression forces and controlling vertical chassis movement. The bump spring cup is essential for off-road vehicles, trucks, and performance-oriented builds where suspension geometry demands reliable spring seating and load distribution.

Manufactured from aluminum and finished with black anodizing, the Bump Spring Cup delivers corrosion resistance and durability in harsh operating environments. The component features a 2.000-inch outer diameter with a precisely machined 0.500-inch thru-hole, allowing for secure fastening and proper spring centering. Black anodized aluminum construction reduces weight while maintaining structural integrity, and the anodized finish provides extended service life against rust and oxidation. This compact, lightweight design integrates seamlessly into existing suspension architectures without compromising clearance or performance.

Builders and suspension technicians rely on SWIFT SPRINGS bump spring cups for lift kit installations, suspension upgrades, and chassis modifications on trucks and off-road vehicles. The 0.500-inch thru-hole accommodates standard suspension bolts and fasteners, simplifying installation and ensuring repeatable alignment. Whether upgrading factory suspension or engineering a custom build, this single-cup design provides the precise geometry needed for consistent bump stop performance. Sold individually, multiple units may be required depending on suspension configuration and vehicle platform.
