Conventional Spring 20in x 5in x 50lb

The SWIFT SPRINGS Conventional Spring 20in x 5in x 50lb (Model 200-500-050) is a heavy-duty coil spring designed for rear suspension applications requiring a 50 lb/in spring rate. This steel spring features a 5-inch outer diameter and 20-inch length, making it suitable for custom suspension builds, off-road vehicles, and equipment requiring consistent load support and shock absorption in high-demand environments.

The 50 lb/in spring rate determines how much force per inch of compression is required to deflect the spring, a critical specification for load-bearing applications. The 20-inch length and conventional coil design allow for straightforward installation in existing suspension systems, while the black powder coat finish provides corrosion protection in outdoor, marine, or salt-air environments. With a total weight of 7.05 lbs, this spring delivers robust support without excessive mass, making it ideal for balanced suspension geometry in both light-duty and moderate-load applications.

This spring is suited for off-road enthusiasts, vehicle customizers, industrial equipment manufacturers, and anyone requiring a replacement or upgrade rear suspension component with predictable spring characteristics. The conventional design works well in applications where linear load response is necessary, such as trailers, recovery equipment, agricultural machinery, and custom suspension systems. Proper installation requires verification of existing spring rates and load requirements to ensure correct performance.

When selecting a replacement spring, spring rate compatibility is essential—using an incorrect rate can compromise vehicle handling, load capacity, and safety. The SWIFT SPRINGS 200-500-050 specification provides a mid-range spring rate suitable for many custom and replacement applications, though users should verify compatibility with their specific suspension system before installation.
