Bump Stop Spring 1600lb

The Bump Stop Spring 1600lb by SWIFT SPRINGS is a precision suspension component engineered to control and limit suspension travel at the final stages of compression. As a mechanic and vehicle modifier, you understand that controlling bottoming-out is critical to ride quality, component longevity, and handling consistency. This bump stop spring protects your suspension's upper travel limit by absorbing energy that would otherwise transfer directly to frame and chassis mounts, preventing metal-to-metal contact that causes harsh impacts and potential suspension damage during aggressive driving or rough terrain.

Rated at 1600 pounds of spring force, this SWIFT SPRINGS component delivers consistent progressive resistance as suspension compresses into its final range. The engineering behind a bump stop spring is straightforward but essential: progressive spring rate means initial compression is softer (allowing compliance on small bumps), but force increases exponentially as the spring nears solid height, effectively cushioning large impacts. The compact 3.35 x 3.3 x 4.75-inch profile and lightweight 0.67-pound design fit within standard suspension geometries without adding rotating mass or complicating packaging. This particular rate is ideal for street and performance applications where a balance between comfort and protection is required, making it a popular upgrade choice for lowered vehicles, track-focused platforms, and custom suspension builds.

Whether you're running coilover upgrades, air suspension systems, or OEM-plus modifications, the 1600lb bump stop spring is most effective on mid-range lowering setups where stock bump stops no longer provide adequate travel limitation. Installation typically involves removing the existing bump stop or elastomer, then nesting this spring into the strut tower, shock mount, or suspension arm depending on your specific vehicle architecture. SWIFT SPRINGS components are trusted by suspension shops and enthusiasts alike for their durability and repeatable performance across thousands of miles of both street and circuit use.
