Bump Stop Spring Flat Wire 700

The SWIFT SPRINGS Bump Stop Spring Flat Wire 700 is a heavy-duty suspension component engineered for vehicles requiring progressive spring rates and impact absorption in demanding off-road or high-performance applications. With a 700 lb/in spring rate and flat wire construction, this bump stop delivers controlled compression and ride stability under extreme load conditions.

The 2.25-inch free length and 2.3-inch outer diameter allow precise fitment within constrained suspension packaging. Flat wire geometry distributes load more evenly across the spring's contact surfaces compared to round-wire designs, reducing stress concentration and improving longevity under cyclic loading. The 700 lb/in rate positions this component in the medium-heavy range, making it suitable for vehicles with upgraded suspension geometry or frequent payload changes. Steel construction with a copper powder coat finish provides corrosion resistance in harsh environments while maintaining consistent spring characteristics across temperature variations.

This bump stop spring is designed for builders and technicians upgrading suspension systems on off-road vehicles, lifted trucks, or performance platforms where OEM compliance isn't adequate. Operators in salt-water, mud, or extreme-terrain environments benefit from the copper powder coat's protective properties. The component is sold individually, allowing installers to replace single units or build matched sets for specific suspension architecture needs.

Bump stop springs are critical secondary suspension elements that prevent metal-to-metal contact when primary springs compress fully, protecting the frame and components from impact damage during off-road events, towing, or sudden load shifts. The SWIFT SPRINGS flat wire design outperforms standard round-wire bump stops by offering superior load distribution and fatigue resistance in high-stress applications.
