8in. x 5in. x 400# Front Spring

The 8in. x 5in. x 400# Front Spring from Landrum Springs is a precision-engineered coil spring designed for vehicle suspension tuning and performance modifications. Built for mechanics and enthusiasts who demand reliability during weight transfer, acceleration, and handling adjustments, this front spring delivers consistent load support for street cars, weekend warriors, and track-focused builds. The 400 lb/in spring rate provides a measured balance between ride comfort and responsive chassis control, making it ideal for both street and strip applications where spring stiffness directly influences vehicle dynamics.

Constructed from high-quality steel and finished with a durable gold powder coat, this conventional coil spring features a 5-inch outer diameter and 8-inch compressed length, engineered to handle front-end load distribution without premature sagging or loss of preload. The 400 lb/in rate means every inch of suspension travel requires 400 pounds of force—critical data for calculating ride height changes, chassis geometry modifications, and weight transfer characteristics. Landrum Springs' Gold Series classification indicates this spring meets strict manufacturing tolerances and material consistency standards, ensuring predictable spring behavior across multiple heat cycles and long-term durability for serious enthusiasts who track their vehicles or demand precision in every component.

This front spring is ideal for builders upgrading independent front suspension systems, lowering kits, and performance suspension packages where OEM springs fall short of handling increased loads or aggressive driving inputs. Mechanics often pair springs at this stiffness with complementary dampers, sway bars, and geometry corrections to optimize cornering response and brake dive control. Verify frame design, vehicle weight, and intended suspension geometry before installation—spring rates are application-specific, and pairing this 8in. x 5in. x 400# front spring with compatible shock absorbers ensures the suspension system works as a tuned unit rather than mismatched components.
