Spring Conv Front 5.5in OD x 9.5in Elite 850lbs

The Spring Conv Front 5.5in OD x 9.5in Elite 850lbs from LANDRUM SPRINGS is a premium coil spring engineered for front-end suspension systems on high-performance and heavy-duty vehicles. Designed for builders and enthusiasts who demand precision handling and load-bearing capability, this convolution-style spring delivers consistent spring rate performance across a wide range of driving conditions. Whether you're upgrading a truck suspension, building a modified street rod, or enhancing a performance vehicle's geometry, this elite-grade spring provides the foundation for responsive, controlled suspension dynamics.

This front coil spring features a 5.5-inch outer diameter and 9.5-inch compressed length, with an 850-pound spring rate that ensures stable load support without excessive stiffness or harshness. The convolution design—characteristic of LANDRUM's Elite series—allows for controlled deflection while minimizing coil bind and maintaining consistent force delivery throughout the suspension travel range. At 9.65 lbs, the spring's mass is optimized for reduced unsprung weight, improving ride quality and steering responsiveness. The durable steel construction withstands repeated cycling and shock loads, making it ideal for both street and light off-road applications where reliability and predictable handling are non-negotiable.

Mechanics and suspension technicians specify LANDRUM Springs for front-end replacement and custom suspension builds on trucks, muscle cars, and modified vehicles requiring precise spring rates. The 850-lb rate suits mid-size trucks and performance vehicles with moderate to heavy spring requirements; verify your vehicle's original spring rate and load capacity before installation to ensure proper suspension geometry and ride height. This spring pairs seamlessly with quality shocks and struts; always replace springs in pairs or complete sets to maintain balanced front-end performance and prevent uneven wear or handling issues.
