Whether your vehicle is set up for everyday street driving, weekend racing at the track, or strictly for show, the Skunk2 Racing adjustable coilover kit is your solution. Each kit comes complete with hard-anodized CNC-machined threaded aluminum sleeves, CNC-wound SAE 9254 racing springs, and mounting hardware that allows up to a 3" drop (sometimes more). Our dual-locking perch design has proven to be the most reliable method for securing the spring perches. The key to the coilover's performance and unsurpassed ride quality is the advanced spring design technology that allows the use of higher spring rates with minimal compromise to ride quality.
