Bump Stop Spring 800lb

The Bump Stop Spring 800lb from SWIFT SPRINGS is a precision-engineered suspension component designed for custom vehicle builds, drag racing, and performance suspension tuning. This round wire bump stop spring provides progressive load support at the end of suspension travel, protecting critical drivetrain and chassis components from hard impacts during extreme acceleration, launch, or rough terrain encounters. It's an essential upgrade for builders who demand reliability and controlled energy dissipation when standard suspension limits are exceeded.

Engineered with an 800 lb/in spring rate, this bump stop delivers firm resistance across its 2.25 inch free length and 2 inch outer diameter, ensuring consistent engagement without excessive bottoming. The steel construction features a copper powder coat finish that resists corrosion and oxidation in harsh underbody environments while maintaining consistent performance across temperature ranges. The round wire design distributes load evenly, preventing stress concentration points that could lead to premature failure or unwanted vibration transfer to the chassis.

This bump stop spring is ideal for drag racers, off-road enthusiasts, and suspension specialists building custom vehicles where predictable compliance at the end of travel is critical. Installation requires mounting within the suspension geometry to contact the axle housing, frame, or suspension arm at full compression, ensuring it activates only when needed. The compact 0.51 lb weight minimizes unsprung mass while the durable copper powder coat ensures longevity even in salt spray or wet climates. Perfect as a replacement component or part of a complete suspension overhaul where precise spring rates are specified by chassis design engineers.
