Bump Stop Cup 2.3in OD Flat Wire

The Bump Stop Cup 2.3in OD Flat Wire by SWIFT SPRINGS is a precision suspension component designed to control and limit suspension travel during extreme compression cycles. This product is ideal for automotive enthusiasts who are building high-performance street machines, preparing for track duty, or engineering custom suspension setups.

Featuring a 2.3-inch outer diameter and a flat wire construction, this bump stop cup optimizes contact surface area and load distribution during compression events. The flat wire design reduces stress concentration points compared to round-wire alternatives, which extends the component's life and provides more progressive engagement as suspension loads increase.

Mechanics and suspension specialists frequently install bump stop cups when upgrading to coilover and lowered suspension systems. This product is particularly beneficial for autocross competitors and daily-driven modified vehicles, ensuring predictable suspension behavior under hard cornering or aggressive acceleration.
