16in Coil Over Spring Progressive

The Landrum Springs 16-inch coil over spring progressive is a precision suspension component designed for vehicle builders, performance mechanics, and enthusiasts seeking tunable ride control without the complexity of full coil-over systems. This spring strikes a balance between stock compliance and competition-grade handling, making it suitable for street-driven builds, autocross platforms, and restorations where variable damping is essential as load and speed conditions change.

The progressive spring design incorporates multiple coil rates within a single unit, with tighter windings engaging progressively as compression increases. This feature provides a softer initial response for bump absorption while increasing stiffness under hard cornering or braking loads. The non-linear rate curve minimizes harshness and prevents bottoming-out, offering a significant advantage over linear springs that may either ride too soft or transmit every road imperfection.

Landrum Springs are commonly specified by professional mechanics for vehicles undergoing independent double-A-arm or strut conversions, particularly in street rod, classic car, and modern performance platforms where OEM springs may not meet handling requirements. This spring integrates seamlessly into compact mounting applications where space is limited, and its progressive geometry extends usable suspension travel, which is crucial for performance vehicles with lower ride heights.
