Swift Springs 3.75" Coil Springs

Swift Springs 3.75” Coil Springs are engineered for enthusiasts who demand the ultimate balance of strength, consistency, and ride quality. Whether you’re racing through desert trails, tackling rock gardens, or fine-tuning a UTV suspension for weekend adventures, Swift Springs delivers unmatched performance and reliability.

Unlike traditional coil springs, Swift uses proprietary H5S.TW material technology, producing a spring that is both lighter and stronger—without sacrificing durability. The result is a coil spring that resists sag, maintains its rate, and provides precise handling with consistent spring performance even under the harshest conditions.
