Our multi pitch TRS springs are a beutiful thing!  This bowling pin style design not only looks cool but it reduces weight, helps spring stability, and is coiled in one continues piece.  This saves a tremendous amount of mechanical bind and shock body wear that you get in conventional multiple spring and transition collar designs.  These springs work on many different applications and are a nice replacement for straight rate designs found on most oem sleds.  These springs are 12.0" in length with the standard 1.90" inside diameter and have a max working travel of 7.0" and come with a coat of liquid black powdercoat!
