Bump Stop Spring 7000lb

The Landrum Springs Bump Stop Spring 7000lb (model ST7000) is a heavy-duty suspension component engineered to control axle movement and absorb impact loads in vehicle chassis applications. With a 7000 lb/in spring rate, this bump stop spring provides firm load support and precise dampening characteristics required in off-road recovery, heavy-duty towing, and performance suspension systems.

Manufactured from steel with a gray powder coat finish, the ST7000 features a 2.125-inch free length and 1.96-inch outer diameter—dimensions that fit standard suspension mounting locations. The 7000 lb/in rate sits in the medium-heavy range, making it suitable for vehicles carrying significant payload or requiring consistent bottoming resistance without excessive harshness. This spring rate prevents frame contact during full compression while maintaining responsive handling characteristics across varied terrain and load conditions.

Bump stop springs are critical for vehicles operating under high-load conditions—whether that's overlanding rigs with extended travel suspension, trucks regularly towing trailers, or performance vehicles with aggressive springs. The ST7000 serves as a secondary spring that engages at the end of suspension travel, preventing metal-to-metal contact and extending component life. The gray powder coat protects against corrosion in varied climates while maintaining a clean appearance. Each unit ships individually, allowing single-spring replacement or matched-pair installation depending on suspension configuration.
