Product Details

Swift Springs Standard Conventional Springs in 5" OD and 8" length are precision-engineered race springs for competitive oval track, stock car, and circle track racing applications. These 5" OD Swift conventional race springs are manufactured in Japan from proprietary H5S.TW high-tensile alloy steel, delivering measurably better traction, weight transfer, and tire temperature consistency compared to standard silicone chrome springs.

Swift Springs has over 90 years of precision spring manufacturing experience, and their conventional race springs are specifically engineered for American racing. With fewer coils and optimized winding, Swift conventional springs reduce unsprung mass and provide faster transient response for a more predictable car through every phase of the corner.

    Great springs

    Swift makes great springs. I haven't put these in yet, running different springs now.

    It's a matter of trial and error to get the car balanced.

    The picture is what is in the car now. The helpers are too soft so I bought assist springs as well.
