Spring 9.5in x 5in x 450 Platinum Front

The EIBACH Spring 9.5in x 5in x 450 Platinum Front coil spring (Part Number PF0950.500.0450) is a precision-engineered suspension component designed for front axle applications requiring a 450 lb/in spring rate. Built from high-quality steel and finished with EIBACH's durable platinum powder coat, this conventional coil spring delivers consistent performance in demanding ride-height and load-handling scenarios where spring rate consistency is critical to vehicle dynamics.

With a 9.5-inch free length and 5-inch outer diameter, this spring is engineered to compress and extend predictably under load cycles—essential for street applications, off-road recovery rigs, or suspension tuning where factory spring rates prove insufficient. The 450 lb/in rate sits in the moderate-to-stiff range, suitable for lifted suspensions, reinforced brackets, or vehicles carrying additional cargo weight that would compress softer springs excessively. The platinum powder coat resists corrosion and rust, extending service life in salt-air environments or high-moisture climates where bare steel would degrade rapidly.

This front spring is ideal for suspension builders, off-road enthusiasts, and fleet operators replacing OEM springs with performance or load-rated alternatives. Buyers should verify fitment with their specific vehicle platform and confirm compatibility with existing dampers and chassis geometry before installation. Spring rate selection directly impacts ride comfort, handling response, and load-carrying capacity—choosing the correct rate is essential to avoiding premature wear or handling issues.

EIBACH Platinum Series springs are recognized for consistent manufacturing tolerances and corrosion resistance, making them a preferred choice in suspension shops and restoration projects where reliability and repeatability matter. This coil spring ships individually and requires proper installation by a qualified technician using appropriate tools and safety equipment.
