The Bump Spring 2IN O.D. x 2.25in 3500lb from EIBACH is a precision suspension bump stop engineered for vehicles that require controlled compression damping and bottoming resistance. Bump stops serve a critical function in modern suspension systems by preventing metal-to-metal contact when suspension components compress fully, thereby protecting frame, axles, and damper assemblies from shock loads during extreme travel. This specialized spring is ideal for lifted trucks, performance vehicles, and off-road platforms where suspension geometry and travel limits demand reliable progressive resistance.
Constructed from high-grade steel and finished in EIBACH's distinctive red powder coat, this bump spring features a 2-inch outer diameter and 2.25-inch free length, with a robust 3500 lb/in spring rate that provides firm resistance without compromising ride comfort during normal articulation. The 3500 lb/in rate is calibrated to engage progressively as suspension nears full compression, absorbing impact energy efficiently and preventing harsh bottom-out conditions. EIBACH's manufacturing precision ensures consistent load characteristics across the entire compression range, critical for maintaining predictable suspension behavior and protecting sensitive drivetrain components during severe off-road use or dynamic driving conditions.
This bump spring suits suspension builders, off-road enthusiasts, and performance shops upgrading vehicles with extended travel kits or modified geometry. Installation requires integration into the suspension's bump stop assembly, typically mounted between the frame and control arm or shock body, where it provides the final stage of compression travel limiting. Weighing just 0.81 pounds and measuring 3.4 x 3.35 x 3.9 inches, it integrates seamlessly into most aftermarket and OEM suspension platforms. Verify mounting location and clearance with your vehicle's suspension blueprint before installation to ensure proper engagement and maximum component protection.
