Curious why not dual rate springs on all 4 corners?
We do offer a dual rate setup. The front end of the XP doesn't benefit from the dual rate, as much as the rear. And with a properly setup front shock (valving/springrate) and little preload, you see an extremely smooth, consistent stroke with the single rate. All of our race cars ran a single rate front end last year as well. But whether you want single rate, dual rate, upgraded shocks etc... we CAN do that
Feel free to PM me with any questions or to order.
