Bump Stop Spring 2500lb

The Bump Stop Spring 2500lb from Landrum Springs is a precision suspension component engineered to prevent frame-to-axle contact during extreme suspension compression events. Whether you're upgrading a lifted truck, tuning a performance off-road vehicle, or fine-tuning a lowered street machine, this bump stop spring protects your chassis from catastrophic damage while maintaining controlled suspension articulation. Bump stops are critical safety components that absorb final-stage compression loads that coil springs or air suspensions cannot fully manage alone.

Landrum Springs manufactures this unit with a 2500-pound spring rate, delivering progressive resistance as compression nears maximum travel. The compact 2.5 x 2.1 x 2.6-inch profile allows integration into tight mounting locations common in modern suspension geometries, while the lightweight 0.53-pound construction minimizes unsprung weight—a critical factor in suspension tuning. The elastomer and spring combination works together to cushion impacts smoothly, reducing transmitted shock loads to frame mounting points and extending component lifespan during rock crawling, jump landings, or aggressive street driving.

This bump stop spring suits builders and mechanics upgrading suspension systems where standard OEM bump stops prove insufficient for the intended duty cycle. Common applications include lifted 4x4 trucks, prerunners, trail trucks, lowered performance vehicles, and custom off-road rigs where suspension travel exceeds factory specifications. Installation requires proper positioning along the suspension arm or frame—typically mounted to contact the axle housing or frame at full compression. Verify mounting geometry and clearance before installation to ensure the bump stop engages smoothly without binding or creating unintended binding in adjacent components.
