Conventional Spring 20in x 5in x 125lb

The SWIFT SPRINGS Conventional Spring 20in x 5in x 125lb (Model 200-500-125) is a precision coil spring engineered for rear suspension applications where consistent load support and predictable spring rate performance are critical. With a 125 lb/in spring constant and 5-inch outside diameter, this spring delivers controlled compression and extension cycles essential for vehicle suspension tuning, automotive restoration projects, and equipment stabilization in demanding field conditions.

Constructed from steel with a black powder coat finish, this conventional spring combines corrosion resistance with durability in outdoor and high-moisture environments. The 20-inch length provides substantial travel capability while the 125 lb/in rate ensures the spring neither under-compresses under load nor over-extends during unloaded cycles. The 5.7 x 5.4 x 20.5-inch dimensions and 8.16-pound weight make this spring suitable for mid-to-heavy-duty rear suspension configurations where weight distribution and load capacity matter for safety and handling predictability.

This coil spring is designed for users who need OEM-quality replacement springs, custom suspension builders tuning rear-end geometry, and fleet maintenance professionals working on truck and trailer systems. The powder-coated steel construction resists rust and oxidation, making it practical for off-road recovery platforms, agricultural equipment, and vehicles operated in salt-air or high-humidity conditions. Each spring is sold individually, allowing builders to replace springs selectively or complete full rear-suspension upgrades one component at a time.
