Bump Stop Spring 500lb

The Bump Stop Spring 500lb from SWIFT SPRINGS is a precision suspension component engineered for tactical and military vehicles requiring controlled suspension articulation and impact absorption. This round-wire bump stop spring is designed for operators who demand reliability under extreme conditions—whether in law enforcement mobile operations, military field deployment, or specialized tactical transport. The 500 lb/in spring rate makes this component ideal for applications requiring firm damping without sacrificing ride control or chassis stability during high-stress maneuvers.

Built from high-grade steel with a durable copper powder coat finish, the Bump Stop Spring 500lb resists corrosion and environmental degradation—critical for vehicles operating in harsh terrain or extended field conditions. The component features a 2-inch outside diameter, 2.25-inch free length, and the precisely calibrated 500 lb/in spring rate provides predictable load response and energy dissipation. The round-wire construction distributes stress evenly across the coil, extending service life and preventing premature failure under repeated compression cycles. This spring rate is specifically tuned for medium-duty suspension systems where adequate bump travel control is essential without over-stiffening the ride.

Military and law enforcement mechanics will recognize this bump stop spring as a replacement or upgrade component for suspension systems on purpose-built tactical platforms and armored transport vehicles. The compact 0.4 lb weight and 3.3 x 3.3 x 4.85-inch footprint make installation straightforward in confined engine compartments and undercarriage locations. Installation requires proper alignment with existing suspension mounts and should be paired with compatible shock absorbers to achieve optimal suspension geometry. Check your vehicle's service manual for exact spring specifications before ordering to ensure correct mounting compatibility.
