12in. x 5.5in. x 900# Front Spring

The Landrum Springs 12-inch x 5.5-inch x 900# Front Spring (Model F900) is a conventional coil spring engineered for vehicle suspension systems requiring precise load support and consistent ride control. Built from high-quality steel with black paint finish, this front spring delivers a 900 lb/in spring rate, making it suitable for applications where medium-to-firm suspension stiffness is required to handle payload, towing, or performance demands without excessive compression or bottoming.

The 12-inch length and 5.5-inch outer diameter specifications are designed to fit standard mounting positions on compatible vehicle frames and suspension assemblies. The 900 lb/in spring rate indicates the force required per inch of deflection—a medium-stiffness characteristic that balances load capacity with ride comfort on trucks, trailers, and utility vehicles. Steel construction with protective black paint coating resists rust and corrosion in typical driving environments. Landrum Springs coil springs are manufactured to OEM and aftermarket standards, ensuring dimensional consistency and predictable performance over extended service life.

This front spring is ideal for vehicle owners and technicians replacing worn or damaged suspension components, restoring factory ride height and handling characteristics, or upgrading to a stiffer spring rate for towing or hauling applications. Proper installation requires verification of vehicle compatibility and correct mounting orientation. Sold individually, allowing for single-spring replacement or matching pairs for full-suspension refresh. Verify fitment against your vehicle's original equipment specifications before purchase.

Landrum Springs is recognized in the automotive aftermarket for producing reliable coil and leaf springs for light-duty and heavy-duty applications. The F900 model represents dependable suspension engineering for maintenance and restoration work across a broad range of vehicle types and uses.
