12in. x 5.5in. x 800# Front Spring

The Landrum Springs 12-inch x 5.5-inch x 800# Front Spring (F800) is a conventional coil spring engineered for front suspension applications requiring robust load support and consistent spring rate performance. With an 800 lb/in spring rate, this Landrum front spring delivers predictable suspension response in a durable steel construction finished in black paint for corrosion resistance and longevity in demanding conditions.

Specification details matter in suspension design: the 5.5-inch outside diameter and 12-inch length are precise dimensions that fit OEM and aftermarket front suspension systems where the 800 lb/in rate is the design match. This spring rate determines how much weight and force the spring compresses per inch of travel—critical for maintaining proper ride height, load distribution, and suspension geometry under load. The steel construction and black paint protect against road salt, moisture, and thermal cycling that degrade suspension components in high-mileage and heavy-use vehicles.

Front springs are core structural components for trucks, SUVs, sedans, and commercial vehicles experiencing suspension wear, sagging, or failure. Replacement springs restore proper ride height, correct body lean during cornering, and eliminate the bottoming-out conditions that signal weakened or broken original springs. Landrum Springs is recognized in the aftermarket suspension industry for manufacturing replacement coil springs that meet or exceed OEM specifications across domestic and import platforms.

This single front spring (sold individually) is a direct replacement component—verify your vehicle's original spring rate, outer diameter, and length before ordering to ensure proper fitment and suspension balance. Suspension work should be performed by qualified technicians who can align the vehicle and verify that both front springs are matched in rate and condition for safe, level handling.
