Product Details
Swift Springs Standard Conventional Front Springs in 5.5" OD and 11" length are precision-engineered front position race springs for competitive oval track and stock car racing. These 5.5" OD Swift front race springs are manufactured in Japan from proprietary H5S.TW high-tensile alloy steel, providing the additional free length and stroke needed for front suspension setups that require more travel than the standard 9.5" length.
With over 90 years of spring manufacturing expertise, Swift Springs delivers measurably better traction, weight transfer, and tire temperature consistency than standard silicone chrome springs. All Swift Springs conventional front springs use H5S.TW alloy for superior fatigue resistance.

- H5S.TW alloy steel provides superior fatigue life and rate consistency
- Designed for front suspension positions requiring additional travel
- Fewer coils reduce unsprung weight for improved mechanical grip
- Faster transient response for better traction on rough track surfaces
- Lower tire temperatures through improved weight transfer
- Swift Springs are made in Japan with precision grinding for even perch seating
