Free Shipping in the United States and Canada After many years of refining the Cygnus Performance X-1 Classic Edition we firmly believe that this is the best affordable coilover set on the market. European style digressive valving provides both ride quality and handling similar to options that cost twice as much or more. Exceptionally high quality first world manufactured pistons, shims, shafts, seals, bearings and oil ensure consistency, silent operation and long service life. Every shock is built in the USA and thoroughly dyno tested. Available proprietary Hyperco springs are similar to what you will find on the most expensive suspension in the world. To learn more about this product please feel free to either contact us or scroll down to the main description where we will go over the coilovers as well as every optional upgrade in great detail.   Please Note: These are custom coilovers that are built to order. We build custom coilovers more efficiently than anyone else in the world which means our typical turnaround time is only one week. However, sometimes components go out of stock and must be reordered. If lead time is absolutely critical please contact us prior to ordering for a current and accurate ETA.
