Coil Over Spring 2.5in x 12in Barrel 150lbs

The Coil Over Spring 2.5in x 12in Barrel 150lbs from Landrum Springs is a precision coil-over suspension component engineered for builders and enthusiasts seeking fine-tuned ride control and adjustable ride height. This spring delivers the progressive spring rate needed for custom suspension setups, whether you're building a lowered street machine, a track-focused road course car, or a competition-level platform. Landrum Springs has been the trusted name in performance coil springs since 1957, and this 150-pound rate unit is ideal for mid-weight applications and dual-spring configurations.

With a 2.5-inch inside diameter and 12-inch barrel length, this coil-over spring integrates seamlessly into coil-over shock kits and allows independent spring preload adjustment for corner balancing and load transfer tuning. The 150-pound spring rate provides a balanced stiffness curve—stiff enough to minimize body roll during aggressive cornering, yet compliant enough to maintain traction on uneven surfaces. The compact 5.8 x 5.8-inch footprint and 4-pound weight make installation straightforward on custom chassis, and the spring's durability ensures consistent performance across multiple driving seasons without sagging or loss of preload tension.

This spring is best suited for builders running dual-spring setups, adjustable coil-over kits, or applications where a medium spring rate is required to support the vehicle's corner weight and desired ride height. Verify compatibility with your coil-over shock body diameter (typically 2.5-inch ID) and shock collar before ordering. Installation requires proper spring compression tools and suspension knowledge; professional installation is recommended to ensure correct preload settings and safe operation. Pair this spring with quality shocks and a complete alignment for optimal handling characteristics and longevity.
