Spring 11in x 5.5in x 1150lb Front Spring

The Spring 11in x 5.5in x 1150lb Front Spring by EIBACH is engineered for drivers and mechanics who demand precision suspension geometry and consistent ride quality. This coil spring is the backbone of modern front-end handling, designed to replace worn or sagging OEM springs that compromise alignment and brake balance. Whether you're restoring a vehicle to factory specifications or upgrading suspension performance, this 1150-pound rate spring delivers the stiffness needed to support chassis loads while maintaining predictable body control during acceleration, braking, and cornering.

Built with EIBACH's proven engineering standards, this front spring features an 11-inch free length and 5.5-inch outer diameter, making it compatible with most late-model suspension housings and strut towers. The 1150-pound spring rate strikes a balance between responsive handling and ride comfort—stiff enough to minimize body roll and diving under braking, yet compliant enough to absorb road imperfections without excessive harshness. At 13.62 lbs, the spring's weight distribution improves unsprung mass characteristics, reducing suspension lag and allowing faster weight transfer during dynamic driving. EIBACH's quality construction ensures consistent rate throughout the spring's lifecycle, eliminating the soft spots that develop in lower-grade alternatives.

This front spring suits mechanics and enthusiasts performing full suspension rebuilds, performance upgrades, or preventive maintenance on aging vehicles. Installation pairs best with complementary damping upgrades—fresh struts or shocks matched to this spring rate ensure optimal ride and handling synergy. Always replace springs in pairs (both front or both rear) to maintain balanced load distribution and prevent uneven tire wear, brake pull, or handling inconsistency. Verify compatibility with your specific vehicle platform before ordering; spring geometry varies significantly across chassis generations and wheelbase configurations.
