Conventional Spring 11in x 5.5in x 400lb 110-550-400

A stiff 400 lb/in spring rate gives you the responsive rear-end geometry you need for consistent cornering and load transfer under hard driving. This conventional coil spring delivers predictable suspension behavior without the complexity of adjustable systems, making it ideal for track-focused builds where reliability matters as much as performance. At 11 inches long with a 5.5-inch OD, it's engineered to fit proven rear suspension platforms and handle repeated high-g cycles.
