Bump Spring Cup

The Bump Spring Cup from SWIFT SPRINGS is a precision suspension component engineered for vehicle builders and mechanics who demand reliability in their suspension systems. This compact cup serves as a critical interface within bump stop assemblies, controlling compression travel and preventing damage to suspension geometry during full-stroke articulation. Whether you're upgrading a daily driver or fine-tuning a lifted truck, the bump spring cup protects your investment by absorbing lateral and vertical loads at the end of suspension travel.

Designed with precision tolerances, the SWIFT SPRINGS bump spring cup maintains consistent load rates and prevents metal-to-metal contact that can cause clunking or suspension damage. The compact 2 x 0.5 x 6 inch profile and lightweight 0.079 lb construction allow for seamless integration into OEM and aftermarket suspensions without adding unsprung weight. This component works in conjunction with elastomer bump stops and spring assemblies to create a progressive resistance curve, extending the lifespan of shocks, struts, and lower control arms by controlling impact forces at full compression.

Mechanics and suspension specialists rely on SWIFT SPRINGS bump spring cups for rebuild kits, suspension upgrades, and collision repairs where factory components need replacement. This part is essential when servicing worn suspension systems, particularly on lifted vehicles, performance applications, or trucks subjected to heavy articulation. Installation typically requires basic hand tools and knowledge of your vehicle's suspension architecture—verify compatibility with your specific make, model, and suspension configuration before ordering.
