Conv Front Spring 11in x 5in 425LB

The Conv Front Spring 11in x 5in 425LB from SWIFT SPRINGS is a heavy-duty conventional coil spring engineered for vehicle suspension systems requiring stable, progressive load support. This front suspension spring is designed for trucks, SUVs, and performance vehicles where consistent ride height and load-carrying capacity are critical. Built to withstand demanding terrain and repeated compression cycles, this spring delivers the predictable performance that serious off-road and tactical vehicle operators demand for reliability in the field.

Manufactured from high-grade steel with a black powder coat finish, this conventional coil spring features an 11-inch free length and 5-inch outer diameter, with a 425 lb/in spring rate that provides firm support without excessive stiffness. The 425-pound-per-inch rate balances load support with ride quality, making it ideal for vehicles carrying tactical gear, communications equipment, or survival supplies. Steel construction ensures durability across temperature extremes, while the black powder coat protects against corrosion and abrasion—critical factors in unpredictable outdoor environments.

This front suspension spring suits operators and vehicle enthusiasts upgrading independent front suspension systems or replacing worn OEM springs. The 425 lb/in rate works best in applications where the vehicle carries moderate to heavy loads consistently, such as expedition vehicles, off-road trucks, and tactical command platforms. Installation requires proper suspension knowledge or professional alignment; paired springs ensure balanced front geometry and safety. Verify your vehicle's suspension design and mounting specifications before purchase to confirm compatibility with your specific platform.
