Bump Stop Spring Flat Wire 600

The Bump Stop Spring Flat Wire 600 by Swift Springs is engineered to control suspension geometry and prevent chassis bottoming in performance-oriented vehicles and heavily modified trucks. This bump stop spring serves as a secondary suspension element, engaging only at extreme compression travel to protect drivetrain components, frame, and suspension hardware from shock loads that exceed primary spring compression limits. Built for enthusiasts who demand precise suspension tuning, the Bump Stop Spring Flat Wire 600 is ideal for lifted vehicles, lowered cars with aggressive geometry, and any platform where bump stop compliance directly impacts handling safety and component longevity.

Designed with flat wire construction, this 600-rate spring delivers consistent, progressive resistance through its compression stroke while maintaining a compact form factor that fits modern suspension packaging constraints. The flat wire design reduces material stress concentration and provides superior damping characteristics compared to round-wire alternatives, translating to smoother bump absorption and reduced vibration transmission to the chassis. Swift Springs engineered this unit to integrate seamlessly with both OEM and aftermarket coil-over systems, offering a 600 lb/in spring rate that balances impact absorption with controlled energy return, ensuring suspension doesn't exceed design limits during extreme off-road travel, track duty, or street performance applications.

Mechanics and suspension shops specify the Bump Stop Spring Flat Wire 600 when building coil-over platforms, custom lowered vehicles, or high-articulation off-road rigs where bottoming prevention is critical. Installation requires proper spring preload measurement and clearance verification to ensure the bump stop engages only under maximum compression; improper installation can create binding or allow frame contact. This spring is compatible with most aftermarket coil-over kits and OEM suspension upgrades that accept flat-wire secondary springs in the 600 lb/in rate category. Verify compatibility with your specific suspension architecture before purchase, as bump stop integration varies across platform-specific suspension designs.
