Bump Spring 2IN O.D. x 2.25in 1750lb

The Bump Spring 2IN O.D. x 2.25in 1750lb by EIBACH is a precision suspension component engineered for vehicles requiring secondary compliance and impact management in their chassis systems. Bump springs, also called helper springs or progressive springs, provide supplementary support during extreme compression events—whether from aggressive off-road terrain, towing applications, or performance driving scenarios. This 1750-pound-rated spring sits between the main spring and frame, activating only when the primary suspension nears full compression, preventing metal-to-metal contact and reducing harshness transmitted to the vehicle structure.

Built to EIBACH's exacting standards, the Bump Spring 2IN O.D. x 2.25in 1750lb features a 2-inch outer diameter and 2.25-inch free length, delivering controlled spring rates optimized for mid-travel to full-compression support. The 1750-pound load rating indicates the spring constant and maximum effective load capacity during bump events, making it ideal for lifted trucks, reinforced suspension builds, and vehicles running coilover systems. EIBACH's manufacturing process ensures consistent wire diameter, coil pitch, and material properties across the entire spring length, guaranteeing repeatable performance and longevity even under repeated heavy compression cycles. The compact footprint (weighing just 0.67 pounds) allows seamless integration into factory or aftermarket suspension architectures without adding excessive unsprung mass.

This bump spring suits mechanics and suspension specialists upgrading trucks, SUVs, and performance vehicles with enhanced ride control and durability requirements. Installation typically pairs the unit with coilover kits, lowering systems, or air suspension setups where progressive spring rates improve comfort during normal driving while maintaining chassis control during extreme articulation or load scenarios. Verify spring seat diameter compatibility and mounting orientation before installation; EIBACH specifications ensure fitment on most modern chassis designs, though custom vehicles may require adapter brackets. For vehicle owners tackling serious terrain or carrying heavy payloads, this component bridges the gap between comfort and protection, extending suspension component lifespan and preventing costly frame damage from bottoming out.
