Bump Spring 1000lb 1.96in OD

The Landrum Springs Bump Spring 1000lb 1.96in OD (model ST24-1000) is a heavy-duty suspension component engineered to manage extreme compression events in vehicles operating under severe conditions. This steel bump stop spring provides progressive rate control at the end of suspension travel, preventing bottoming-out and protecting frame and chassis components during aggressive off-road use, recovery operations, or high-load driving scenarios where standard suspension geometry reaches its limit.

With a spring rate of 1000 lb/in and a free length of 2.4 inches, this bump spring delivers the resistance needed to control deep suspension compressions without transferring shock directly to the vehicle frame. The 1.96-inch outer diameter fits standard suspension mounting points, while the gray powder coat finish provides corrosion resistance in wet, muddy, and salt-air environments. At 0.44 lbs, the spring adds minimal unsprung weight, critical for maintaining suspension responsiveness and ride quality.

This component is essential for lifted trucks, rock crawlers, and expedition vehicles where suspension travel is maximized and bottoming-out is a real risk during heavy impacts. It's also used in recovery rigs, off-road racing platforms, and vehicles carrying significant payload weight. The ST series from Landrum Springs is recognized for precision engineering and consistent rate characteristics, making it a reliable choice for builders and technicians who demand predictable suspension behavior across multiple compression cycles.

Bump springs serve a distinct role in suspension design—they are not replacement coil springs but supplementary components that activate only at extreme compression. Proper installation requires understanding your vehicle's suspension geometry and load requirements. Each unit is sold individually, so verify your suspension system's configuration and compression limits before ordering.
