Bump Stop Spring 700lb

The Landrum Springs Bump Stop Spring 700lb (model ST700) is a precision-engineered suspension component designed to limit suspension travel and absorb impact energy in high-performance automotive applications. With a spring rate of 700 lb/in and a 2.125-inch free length, this bump stop spring provides controlled compression when a vehicle's suspension reaches maximum droop or rebound, preventing damage to suspension components and frame structure during extreme articulation or heavy impact scenarios.

Constructed from steel and finished with a gray powder coat, the ST700 measures 1.96 inches in outer diameter and is rated for 700 lb/in spring rate—a specification that determines how much force is required to compress the spring by one inch. This stiffness level is critical for vehicles that experience frequent bottom-out scenarios, such as off-road recovery operations, heavy towing, or competition suspension setups. The powder coat finish provides corrosion resistance in harsh environmental conditions, extending service life in both wet and dust-laden environments.

This bump stop spring is suited for builders and technicians upgrading or repairing suspension systems on trucks, off-road vehicles, and performance platforms where suspension geometry and travel limits must be precisely managed. Landrum Springs components are widely used in fabrication shops, restoration projects, and custom suspension builds where OEM or aftermarket bump stop replacement is required. The ST700's compact 0.38 lb weight and standard dimensions make it a direct replacement or upgrade component for applications requiring this specific spring rate and geometry.
