Bump Stop Spring 400lbs

The Bump Stop Spring 400lbs from HYPERCO is a precision suspension component engineered for vehicles requiring controlled compression and impact absorption during suspension travel. Bump stops function as a secondary cushioning system, protecting chassis geometry and drivetrain components when the suspension reaches maximum compression under load, braking events, or rough terrain. This 400 lb/in rated spring is designed for builders and technicians who demand reliable performance in lifted trucks, performance vehicles, and off-road applications where suspension articulation is critical.

Constructed from high-grade steel with a blue powder coat finish, the Bump Stop Spring 400lbs features a 2.4-inch free length and 1.92-inch outer diameter, delivering a spring rate of 400 pounds per inch. This specification ensures progressive resistance as suspension compresses, preventing bottoming-out while maintaining ride comfort and handling response. The robust steel construction and corrosion-resistant powder coating provide durability in harsh environments, whether exposed to road salt, mud, or continuous articulation cycles. The compact geometry allows integration into most modern suspension designs without clearance conflicts.

Off-road enthusiasts, suspension tuners, and OEM restoration specialists benefit most from this bump stop spring, particularly when upgrading lifted suspensions or fine-tuning compression behavior on performance platforms. Installation requires suspension disassembly and proper preload adjustment to achieve optimal ride height and damping characteristics. The 0.6-pound weight makes handling simple, and the compact 4.4 x 4.3 x 7.25-inch footprint ensures compatibility across a wide range of suspension architectures. Pair with matched bump stop components and dampers for complete suspension system performance.
