Single action truck. Used on single action plates like the Cyclone, Cyclone NTS, Invader and Magnum plates. Many people will upgrade to the newer DA45 truck but we still offer the single-action format here. Will require the use of a nylon washer between the kingpin head and the truck casting. If you are needing these please reach out to us before or after ordering. Sold as a set of 4 and listing is for truck and axle only.
