Spring 9.5in x 5in x 650 Platinum Front

The EIBACH Spring 9.5in x 5in x 650 Platinum Front coil spring is a precision-engineered suspension component designed for front-end applications in performance and heavy-duty vehicles. Built to EIBACH's exacting standards, this coil spring delivers consistent spring rate performance with a 650 lb/in rating, making it ideal for systems requiring substantial load support and controlled compression characteristics. The platinum powder-coat finish provides corrosion resistance and durability in demanding environments.

At 9.5 inches in length with a 5-inch outer diameter, this front coil spring is engineered to fit specific vehicle platforms where OEM or performance suspension geometry demands precise fitment. The 650 lb/in spring constant is the critical specification—this determines how much force is required to compress the spring one inch, directly impacting ride height, load capacity, and suspension response. Heavier spring rates like this one are typically chosen for vehicles carrying sustained loads, towing applications, or performance setups requiring reduced suspension travel. The conventional coil design ensures compatibility with standard suspension mounting points and geometry.

This spring suits mechanics, fabricators, and vehicle owners upgrading or replacing factory suspension on trucks, SUVs, or performance vehicles. It is sold as a single unit, so paired front applications require two springs. The platinum powder coat—a premium EIBACH finish—resists salt spray, UV degradation, and road chemicals better than standard paint, extending service life in corrosive environments. Proper installation requires alignment and suspension geometry verification after replacement.

EIBACH coil springs are recognized in the aftermarket for precision manufacturing and consistent performance across automotive and light-duty truck segments. This Platinum Series front spring is a direct-replacement or upgrade component suitable for suspension tuning where increased spring rates are specified by the vehicle platform or performance build requirements.
