This kit is not yet a full production run kit, so all components are not our signature blue anodized color. It is precision CNC machined from solid aluminum billet however, and looks very professional and fits very well. The kit includes everything necessary to complete the installation including all hardware, the correct size drill bit, name brand thread lock compound, a full warning placard set, and clear installation instructions.
 
All of our interlock kits are proudly made in the USA!
