Bump Spring 2IN O.D. x 2.25in 5000lb

The Bump Spring 2IN O.D. x 2.25in 5000lb by Eibach is a precision suspension component engineered to absorb and control vertical chassis movement during extreme articulation, bottoming events, or high-impact terrain. Built for off-road vehicles, racing platforms, and tactical mobility systems, this bump stop spring prevents metal-to-metal contact and chassis damage when suspension reaches full compression. Whether you're operating in desert environments, rock crawling, or managing heavy payload dynamics, this spring isolates critical drivetrain and frame components from shock loads that standard suspension alone cannot manage.

This 2.25-inch free-length spring features a 2-inch outer diameter and delivers a 5000 lb/in spring rate, providing firm progressive resistance without binding or premature engagement. Manufactured from high-grade steel and finished with a durable red powder coat, the Eibach bump spring resists corrosion, UV degradation, and thermal cycling—critical for vehicles exposed to harsh outdoor conditions. The compact 3.4 x 3.4 x 3.7-inch form factor allows installation in tight suspension geometry while maintaining consistent load response across repeated compression cycles. At just 0.82 lbs, weight penalty is minimal, making it ideal for performance-tuned applications where chassis compliance matters.

Vehicle builders, off-road enthusiasts, and suspension engineers rely on Eibach bump springs for predictable control during aggressive driving or heavy-load conditions. Installation typically occurs on coil-over systems, independent front suspension (IFS), or independent rear suspension (IRS) platforms where secondary spring compression is needed. This individual spring allows targeted tuning—stack multiple units to increase bump stop rate or select single-spring configuration for baseline protection. Verify mounting compatibility with your vehicle's suspension architecture and confirm clearance with existing components before installation. For optimal performance, pair with complementary shocks and primary springs matched to your vehicle's weight and intended use profile.
